\`configure' configures this package to adapt to many kinds of systems.
 
Usage: $0 [OPTION]... [VAR=VALUE]...
 
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
 
Defaults for the options are specified in brackets.
 
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']
 
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
 
By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
 
For better control, use the options below.
 
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]

The C library used through out +this manual is @code{newlib}. Newlib is a ANSI conforming C library +developed by Cygnus Support. Libgloss could easily be made to +support other C libraries, and it can be used standalone as well. The +standalone configuration is typically used when bringing up new +hardware, or on small systems. + +For a long time, these details were part of newlib. This approach worked +well when a complete tool chain only had to support one system. A tool +chain refers to the series of compiler passes required to produce a +binary file that will run on an embedded system. For C, the passes are +cpp, gcc, gas, ld. Cpp is the preprocessor, which process all the header +files and macros. Gcc is the compiler, which produces assembler from the +processed C files. Gas assembles the code into object files, and then ld +combines the object files and binds the code to addresses and produces +the final executable image. + +Most of the time a tool chain does only have to support one target +execution environment. An example of this would be a tool chain for the +AMD 29k processor family. All of the execution environments for this +processor are have the same interface, the same memory map, and the same +I/O code. In this case all of the support code is in newlib/sys/FIXME. +Libgloss's creation was forced initially be the @code{cpu32} processor +family. There are many different execution environments for this line, +and they vary wildly. newlib itself has only has a few dependencies that +it needs for each target. These are explained later in this doc. The +hardware dependent part of newlib was reorganized into a separate +directory structure within newlib called the stub dirs. It was initially +called this because most of the routines newlib needs for a target were +simple stubs that do nothing, but return a value to the application. They +only exist so the linker can produce a final executable image. This work +was done during the early part of 1993. + +After a while it became apparent that this approach of isolating the +hardware and systems files together made sense. Around this same time +the stub dirs were made to run standalone, mostly so it could also be +used to support GDB's remote debugging needs. At this time it was +decided to move the stub dirs out of newlib and into it's own separate +library so it could be used standalone, and be included in various other +GNU tools without having to bring in all of newlib, which is large. The +new library is called Libgloss, for Gnu Low-level OS support. + +@menu +* Supported targets:: What targets libgloss currently + supports. +* Building libgloss:: How to configure and built libgloss + for a target. +* Board support:: How to add support for a new board. +@end menu + +@node Supported targets, Building libgloss, Libgloss, Libgloss +@section Supported Targets +Currently libgloss is being used for the following targets: + +@menu +* Sparclite:: Fujitsu's sparclite. +* CPU32:: Various m68k based targets. +* Mips:: Mips code based targets. +* PA-RISC:: Precision Risc Organization.. +@end menu + +@node Sparclite, CPU32, , Supported targets +@subsection Sparclite Targets Supported +@c FIXME: put links to the docs in etc/targetdoc +This is for the Fujitsu Sparclite family of processors. Currently this +covers the ex930, ex931, ex932, ex933, and the ex934. In addition to the +I/O code a startup file, this has a GDB debug-stub that gets linked into +your application. This is an exception handler style debug stub. For +more info, see the section on Porting GDB. @ref{GDB,,Porting GDB}. + +The Fujitsu eval boards use a host based terminal program to load and +execute programs on the target. This program, @code{pciuh} is relatively +new (in 1994) and it replaced the previous ROM monitor which had the +shell in the ROM. GDB uses the the GDB remote protocol, the relevant +source files from the gdb sources are remote-sparcl.c. The debug stub is +part of libgloss and is called sparcl-stub.c. + +@node CPU32, Mips, Sparclite, Supported targets +@subsection Motorola CPU32 Targets supported +This refers to Motorola's m68k based CPU32 processor family. The crt0.S +startup file should be usable with any target environment, and it's +mostly just the I/O code and linker scripts that vary. Currently there +is support for the Motorola MVME line of 6U VME boards and IDP +line of eval boards. All of the +Motorola VME boards run @code{Bug}, a ROM based debug monitor. +This monitor has the feature of using user level traps to do I/O, so +this code should be portable to other MVME boards with little if any +change. The startup file also can remain unchanged. About the only thing +that varies is the address for where the text section begins. This can +be accomplished either in the linker script, or on the command line +using the @samp{-Ttext [address]}. + +@c FIXME: Intermetrics or ISI wrote rom68k ? +There is also support for the @code{rom68k} monitor as shipped on +Motorola's IDP eval board line. This code should be portable across the +range of CPU's the board supports. There is also GDB support for this +target environment in the GDB source tree. The relevant files are +gdb/monitor.c, monitor.h, and rom58k-rom.c. The usage of these files is +discussed in the GDB section. + +@node Mips, PA-RISC, CPU32, Supported targets +@subsection Mips core Targets Supported +The Crt0 startup file should run on any mips target that doesn't require +additional hardware initialization. The I/O code so far only supports a +custom LSI33k based RAID disk controller board. It should easy to +change to support the IDT line of eval boards. Currently the two +debugging protocols supported by GDB for mips targets is IDT's mips +debug protocol, and a customized hybrid of the standard GDB remote +protocol and GDB's standard ROM monitor support. Included here is the +debug stub for the hybrid monitor. This supports the LSI33k processor, +and only has support for the GDB protocol commands @code{g}, @code{G}, +@code{m}, @code{M}, which basically only supports the register and +memory reading and writing commands. This is part of libgloss and is +called lsi33k-stub.c. + +The crt0.S should also work on the IDT line of eval boards, but has only +been run on the LSI33k for now. There is no I/O support for the IDT eval +board at this time. The current I/O code is for a customized version of +LSI's @code{pmon} ROM monitor. This uses entry points into the monitor, +and should easily port to other versions of the pmon monitor. Pmon is +distributed in source by LSI. + +@node PA-RISC, , Mips, Supported targets +@subsection PA-RISC Targets Supported +This supports the various boards manufactured by the HP-PRO consortium. +This is a group of companies all making variations on the PA-RISC +processor. Currently supported are ports to the WinBond @samp{Cougar} +board based around their w89k version of the PA. Also supported is the +Oki op50n processor. + +There is also included, but never built an unfinished port to the HP 743 +board. This board is the main CPU board for the HP700 line of industrial +computers. This target isn't exactly an embedded system, in fact it's +really only designed to load and run HP-UX. Still, the crt0.S and I/O +code are fully working. It is included mostly because their is a barely +functioning exception handler GDB debug stub, and I hope somebody could +use it. The other PRO targets all use GDB's ability to talk to ROM +monitors directly, so it doesn't need a debug stub. There is also a +utility that will produce a bootable file by HP's ROM monitor. This is +all included in the hopes somebody else will finish it. :-) + +Both the WinBond board and the Oki board download srecords. The WinBond +board also has support for loading the SOM files as produced by the +native compiler on HP-UX. WinBond supplies a set of DOS programs that +will allow the loading of files via a bidirectional parallel port. This +has never been tested with the output of GNU SOM, as this manual is +mostly for Unix based systems. + +@node Building libgloss, Board support, Supported targets, Libgloss +@section Configuring and building libgloss. + +Libgloss uses an autoconf based script to configure. Autoconf scripts +are portable shell scripts that are generated from a configure.in file. +Configure input scripts are based themselves on m4. Most configure +scripts run a series of tests to determine features the various +supported features of the target. For features that can't be determined +by a feature test, a makefile fragment is merged in. The configure +process leaves creates a Makefile in the build directory. For libgloss, +there are only a few configure options of importance. These are --target +and --srcdir. + +Typically libgloss is built in a separate tree just for objects. In this +manner, it's possible to have a single source tree, and multiple object +trees. If you only need to configure for a single target environment, +then you can configure in the source tree. The argument for --target is +a config string. It's usually safest to use the full canonical opposed +to the target alias. So, to configure for a CPU32 (m68k) with a separate +source tree, use: + +@smallexample +../src/libgloss/configure --verbose --target m68k-coff +@end smallexample + +The configure script is in the source tree. When configure is invoked +it will determine it's own source tree, so the --srcdir is would be +redundant here. + +Once libgloss is configured, @code{make} is sufficient to build it. The +default values for @code{Makefiles} are typically correct for all +supported systems. The test cases in the testsuite will also built +automatically as opposed to a @code{make check}, where test binaries +aren't built till test time. This is mostly cause the libgloss +testsuites are the last thing built when building the entire GNU source +tree, so it's a good test of all the other compilation passes. + +The default values for the Makefiles are set in the Makefile fragment +merged in during configuration. This fragment typically has rules like + +@smallexample +CC_FOR_TARGET = `if [ -f $$@{OBJROOT@}/gcc/xgcc ] ; \ + then echo $@{OBJROOT@}/gcc/xgcc -B$@{OBJROOT@}/gcc/ ; \ + else t='$@{program_transform_name@}'; echo gcc | sed -e '' $$t ; fi` +@end smallexample + +Basically this is a runtime test to determine whether there are freshly +built executables for the other main passes of the GNU tools. If there +isn't an executable built in the same object tree, then +@emph{transformed}the generic tool name (like gcc) is transformed to the +name typically used in GNU cross compilers. The names are +typically based on the target's canonical name, so if you've configured +for @code{m68k-coff} the transformed name is @code{m68k-coff-gcc} in +this case. If you install with aliases or rename the tools, this won't +work, and it will always look for tools in the path. You can force the a +different name to work by reconfiguring with the +@code{--program-transform-name} option to configure. This option takes a +sed script like this @code{-e s,^,m68k-coff-,} which produces tools +using the standard names (at least here at Cygnus). + +The search for the other GNU development tools is exactly the same idea. +This technique gets messier when build options like @code{-msoft-float} +support are used. The Makefile fragments set the @code{MUTILIB} +variable, and if it is set, the search path is modified. If the linking +is done with an installed cross compiler, then none of this needs to be +used. This is done so libgloss will build automatically with a fresh, +and uninstalled object tree. It also makes it easier to debug the other +tools using libgloss's test suites. + +@node Board support, , Building libgloss, Libgloss +@section Adding Support for a New Board + +This section explains how to add support for a new board to libgloss. +In order to add support for a board, you must already have developed a +toolchain for the target architecture. + +All of the changes you will make will be in the subdirectory named +after the architecture used by your board. For example, if you are +developing support for a new ColdFire board, you will modify files in +the @file{m68k} subdirectory, as that subdirectory contains support +for all 68K devices, including architecture variants like ColdFire. + +In general, you will be adding three components: a @file{crt0.S} file +(@pxref{Crt0}), a linker script (@pxref{Linker Scripts}), and a +hardware support library. Each should be prefixed with the name of +your board. For example, if you ard adding support for a new Surf +board, then you will be adding the assembly @file{surf-crt0.S} (which +will be assembled into @file{surf-crt0.o}), the linker script +@file{surf.ld}, and other C and assembly files which will be combined +into the hardware support library @file{libsurf.a}. + +You should modify @file{Makefile.in} to define new variables +corresponding to your board. Although there is some variation between +architectures, the general convention is to use the following format: + +@example +# The name of the crt0.o file. +SURF_CRT0 = surf-crt0.o +# The name of the linker script. +SURF_SCRIPTS = surf.ld +# The name of the hardware support library. +SURF_BSP = libsurf.a +# The object files that make up the hardware support library. +SURF_OBJS = surf-file1.o surf-file2.o +# The name of the Makefile target to use for installation. +SURF_INSTALL = install-surf +@end example + +Then, you should create the @code{$@{SURF_BSP@}} and +@code{$@{SURF_INSTALL@}} make targets. Add @code{$@{SURF_CRT0@}} to +the dependencies for the @code{all} target and add +@code{$@{SURF_INSTALL@}} to the dependencies for the @code{install} +target. Now, when libgloss is built and installed, support for your +BSP will be installed as well. + +@node GCC, Libraries, Libgloss, Top +@chapter Porting GCC + +Porting GCC requires two things, neither of which has anything to do +with GCC. If GCC already supports a processor type, then all the work in +porting GCC is really a linker issue. All GCC has to do is produce +assembler output in the proper syntax. Most of the work is done by the +linker, which is described elsewhere. + +Mostly all GCC does is format the command line for the linker pass. The +command line for GCC is set in the various config subdirectories of gcc. +The options of interest to us are @code{CPP_SPEC} and +@code{STARTFILE_SPEC}. CPP_SPEC sets the builtin defines for your +environment. If you support multiple environments with the same +processor, then OS specific defines will need to be elsewhere. +@c FIXME: Check these names + +@code{STARTFILE_SPEC} + +Once you have linker support, GCC will be able to produce a fully linked +executable image. The only @emph{part} of GCC that the linker wants is a +crt0.o, and a memory map. If you plan on running any programs that do +I/O of any kind, you'll need to write support for the C library, which +is described elsewhere. + +@menu +* Overview:: An overview as to the compilation passes. +* Options:: Useful GCC options for embedded systems. +@end menu + +@node Overview, Options, , GCC +@section Compilation passes + +GCC by itself only compiles the C or C++ code into assembler. Typically +GCC invokes all the passes required for you. These passes are cpp, cc1, +gas, ld. @code{cpp} is the C preprocessor. This will merge in the +include files, expand all macros definitions, and process all the +@code{#ifdef} sections. To see the output of ccp, invoke gcc with the +@code{-E} option, and the preprocessed file will be printed on the +stdout. cc1 is the actual compiler pass that produces the assembler for +the processed file. GCC is actually only a driver program for all the +compiler passes. It will format command line options for the other passes. +The usual command line GCC uses for the final link phase will have LD +link in the startup code and additional libraries by default. + +GNU AS started it's life to only function as a compiler pass, but +these days it can also be used as a source level assembler. When used as +a source level assembler, it has a companion assembler preprocessor +called @code{gasp}. This has a syntax similar to most other assembler +macros packages. GAS emits a relocatable object file from the assembler +source. The object file contains the executable part of the application, +and debug symbols. + +LD is responsible for resolving the addresses and symbols to something +that will be fully self-contained. Some RTOS's use relocatable object +file formats like @code{a.out}, but more commonly the final image will +only use absolute addresses for symbols. This enables code to be burned +into PROMS as well. Although LD can produce an executable image, there +is usually a hidden object file called @code{crt0.o} that is required as +startup code. With this startup code and a memory map, the executable +image will actually run on the target environment. @ref{Crt0,,Startup +Files}. + +The startup code usually defines a special symbol like @code{_start} +that is the default base address for the application, and the first +symbol in the executable image. If you plan to use any routines from the +standard C library, you'll also need to implement the functions that +this library is dependent on. @ref{Libraries,,Porting Newlib}. + +@node Options, , Overview, GCC +@c FIXME: Need stuff here about -fpic, -Ttext, etc... + +Options for the various development tools are covered in more detail +elsewhere. Still, the amount of options can be an overwhelming amount of +stuff, so the options most suited to embedded systems are summarized +here. If you use GCC as the main driver for all the passes, most of the +linker options can be passed directly to the compiler.

The initial piece of startup code is +called a crt0. (C RunTime 0) This is usually written in assembler, and +it's object gets linked in first, and bootstraps the rest of the +application when executed. This file needs to do the following things. + +@enumerate +@item +Initialize anything that needs it. This init section varies. If you are +developing an application that gets download to a ROM monitor, then +there is usually no need for any special initialization. The ROM monitor +handles it for you. + +If you plan to burn your code in a ROM, then the crt0 typically has to +do all the hardware initialization that is required to run an +application. This can include things like initializing serial ports or +run a memory check. It all depends on the hardware. + +@item +Zero the BSS section. This is for uninitialized data. All the addresses in +this section need to be initialized to zero so that programs that forget +to check new variables default value will get unpredictable results. + +@item +Call main() +This is what basically starts things running. If your ROM monitor +supports it, then first setup argc and argv for command line arguments +and an environment pointer. Then branch to main(). For G++ the the main +routine gets a branch to __main inserted by the code generator at the +very top. __main() is used by G++ to initialize it's internal tables. +__main() then returns back to your original main() and your code gets +executed. + +@item +Call exit() +After main() has returned, you need to cleanup things and return control +of the hardware from the application. On some hardware, there is nothing +to return to, especially if your program is in ROM.

Open & close +don't need to be fully supported unless you have a filesystems, so +typically they are stubbed out. Kill is also a stub, since you can't do +process control on an embedded system. + +Sbrk() is only needed by applications that do dynamic memory +allocation. It's uses the symbol @code{_end} that is setup in the linker +script. It also requires a compile time option to set the upper size +limit on the heap space.

Commonly more than one kind of GDB interface is used to cober +a wide variety of development needs. + +The most common style of GDB backend is an exception handler for +breakpoints. This is also called a @emph{gdb stub}, and is requires the +two additional lines of init code in your @code{main()} routine. The GDB +stubs all use the GDB @emph{remote protocol}. When the application gets a +breakpoint exception, it communicates to GDB on the host. + +Another common style of interfacing GDB to a target is by using an +existing ROM monitor. These break down into two main kinds, a similar +protocol to the GDB remote protocol, and an interface that uses the ROM +monitor directly. This kind has GDB simulating a human operator, and all +GDB does is work as a command formatter and parser. + +@menu +* GNU remote protocol:: The standard remote protocol. +* Exception handler:: A linked in exception handler. +* ROM monitors:: Using a ROM monitor as a backend. +* Other remote protocols:: Adding support for new protocols. +@end menu + +@node GNU remote protocol, Exception handler, ,GDB +@section The standard remote protocol + +The standard remote protocol is a simple, packet based scheme.

If @emph{} starts with two characters +followed by @code{:}, then the existing stubs interpret this as a +sequence number. For example, the command @code{g} is used to read the +values of the registers. So, a packet to do this would look like + +@smallexample + $g#67 +@end smallexample + +@emph{CSUM1} and @emph{CSUM2} are an ascii representation in hex of an +8-bit checksum of @emph{}, the most significant nibble is sent first. +the hex digits 0-9,a-f are used. + +A simple protocol is used when communicating with the target. This is +mainly to give a degree of error handling over the serial cable. For +each packet transmitted successfully, the target responds with a +@code{+} (@code{ACK}). If there was a transmission error, then the target +responds with a @code{-} (@code{NAK}). An error is determined when the +checksum doesn't match the calculated checksum for that data record. +Upon reciept of the @code{ACK}, @code{GDB} can then transmit the next +packet. + +Here is a list of the main functions that need to be supported. Each data +packet is a command with a set number of bytes in the command packet. +Most commands either return data, or respond with a @code{NAK}. Commands +that don't return data respond with an @code{ACK}. All data values are +ascii hex digits. Every byte needs two hex digits to represent t. This +means that a byte with the value @samp{7} becomes @samp{07}. On a 32 bit +machine this works out to 8 characters per word. All of the bytes in a +word are stored in the target byte order. When writing the host side of +the GDB protocol, be careful of byte order, and make sure that the code +will run on both big and little endian hosts and produce the same answers. + +These functions are the minimum required to make a GDB backend work.

The exception handler needs +to communicate to GDB on the host whenever there is a breakpoint +exception. When GDB starts a program running on the target, it's polling +the serial port during execution looking for any debug packets. So when +a breakpoint occurs, the exception handler needs to save state, and send +a GDB remote protocol packet to GDB on the host. GDB takes any output +that isn't a debug command packet and displays it in the command window. + +Support for the exception handler varies between processors, but the +minimum supported functions are those needed by GDB. These are functions +to support the reading and writing of registers, the reading and writing +of memory, start execution at an address, single step, and last signal. +Sometimes other functions for adjusting the baud rate, or resetting the +hardware are implemented. + +Once GDB gets the command packet from the breakpoint, it will read a few +registers and memory locations an then wait for the user. When the user +types @code{run} or @code{continue} a @code{continue} command is issued +to the backend, and control returns from the breakpoint routine to the +application. + +@node ROM monitors, Other remote protocols, Exception handler, GDB +@section Using a ROM monitor as a backend +GDB also can mimic a human user and use a ROM monitors normal debug +commands as a backend. This consists mostly of sending and parsing +@code{ASCII} strings. All the ROM monitor interfaces share a common set +of routines in @code{gdb/monitor.c}. This supports adding new ROM +monitor interfaces by filling in a structure with the common commands +GDB needs. GDb already supports several command ROM monitors, including +Motorola's @code{Bug} monitor for their VME boards, and the Rom68k +monitor by Integrated Systems, Inc. for various m68k based boards. GDB +also supports the custom ROM monitors on the WinBond and Oki PA based +targets. There is builtin support for loading files to ROM monitors +specifically. GDB can convert a binary into an srecord and then load it +as an ascii file, or using @code{xmodem}. + +@c FIXME: do I need trademark somethings here ?
