2003-02-27 Nick Garnett <nickg@calivar.com>
* include/mips-stub.h: Disabled option that makes MIPS32 targets
use 64 bit registers in GDB protocol. The standard GDB does not
support this, only MIPS own version.
2003-01-31 Mark Salter <msalter@redhat.com>
* src/hal_syscall.c (hal_syscall_handler): Let generic syscall code
handle exit.
2003-01-09 Tim Michals <t.michals@attbi.com>
* src/hal_misc.c (hal_delay_us): Use HAL_CLOCK_READ instead of inline
asm, to allow for variant/platform HAL packages overriding.
2002-12-12 Bart Veer <bartv@ecoscentric.com>
* include/hal_cache.h: allow for cache flushes etc. where the base
address is not aligned to a cacheline boundary.
2002-08-02 Andrew Lunn <Andrew.Lunn@ascom.ch>
* cdl/hal_mips.cdl: Redboot exec command can now be disabled
by CDL
2002-05-17 Jesper Skov <jskov@redhat.com>
* include/hal_intr.h: Fix CYGNUM_HAL_EXCEPTION_MIN definition so
it reflects the FPU configuration.
2002-04-30 Jesper Skov <jskov@redhat.com>
* include/hal_intr.h: Only define decoded FPU vectors if these are
actually used. This allows tests to check for capabilities and do
N/A when appropriate.
2002-04-15 Jonathan Larmour <jlarmour@redhat.com>
* src/hal_syscall.c (hal_syscall_handler): Add extra sig argument to
__do_syscall.
2002-03-21 Nick Garnett <nickg@redhat.com>
* include/hal_cache.h: Added macros to adjust the size argument to
some of the cache macros to a whole multiple of the cache line
size. Otherwise, for some values of the arguments, we can miss the
last line.
2001-12-17 Jesper Skov <jskov@redhat.com>
* include/hal_arch.h (CYGARC_HAL_GET_RETURN_ADDRESS,
(CYGARC_HAL_GET_RETURN_ADDRESS_BACKUP): Added dummy arguments.
* src/hal_misc.c (cyg_hal_exception_handler): Fix warning.
2001-12-04 Nick Garnett <nickg@redhat.com>
* src/hal_misc.c: Added hal_arch_program_new_stack() to support
running user programs on a new stack placed at the top of RAM.
* src/vectors.S: Added hal_program_new_stack function to support
hal_arch_program_new_stack(). This does the actual stack
switching.
* include/mips-stub.h (NUMREGS):
* include/mips-regs.h (NUM_REGS):
Added test to correctly define these when the target expects the
CP0 registers to be reported to GDB
* include/hal_arch.h: Added support for fetching CP0 registers in
MIPS64 platforms for GDB. Reorganized the code slightly.
* cdl/hal_mips.cdl:
Added define_proc to define HAL_ARCH_PROGRAM_NEW_STACK.
2001-11-16 Nick Garnett <nickg@redhat.com>
* src/hal_misc.c (hal_msbit_index): Fixed this function so that it
actually works!
2001-10-24 Nick Garnett <nickg@redhat.com>
* src/vectors.S:
Change behaviour of __default_exception_vsr to only switch to
interrupt stack if we are not already on it. This is now similar
to the way the interrupt VSR operates. This is necessary since it
is possible to take exceptions (such as TLB miss or address error)
while running in the GDB stubs.
* src/hal_misc.c (cyg_hal_exception_handler): Ensure that PC
planted when catching stub exceptions gets sign extended where
necessary in 64 bit platforms.
2001-10-05 Jesper Skov <jskov@redhat.com>
* include/hal_arch.h: Provide CYGARC_CACHED_ADDRESS() and friends
without casting for use in assembler files.
2001-09-17 Nick Garnett <nickg@redhat.com>
* src/hal_misc.c (hal_delay_us): Rewrote this routine to work
correctly in higher speed CPUs. The counter register counts at
half CPU clock speed. The original ticks calculation could
overflow very easily. For example in a 133MHz CPU, it overflowed
with any argument greater than 32! This is another of those "how
did it ever work?" things.
* include/hal_arch.h: Added casts to CYGARC_PHYSICAL_ADDRESS() and
friends.
2001-09-07 Nick Garnett <nickg@redhat.com>
* include/mips-stub.h: Returned target_register_t to long long
type for VR4300 target. This is the only platform that does 64bit
register saves/restores, and the GDB registers must be full sized.
* include/arch.inc: Added option to select correct initial SR
value when the startup is ROMRAM.
Disabled setting of status and config registers when using a ROM
monitor. The monitor should have already set these to appropriate
values.
2001-08-22 Gary Thomas <gthomas@redhat.com>
* src/redboot_linux_exec.c:
printf() is no longer a part of RedBoot. Thus all programs
must use diag_printf() and related functions instead.
2001-08-01 Hugo Tyson <hmt@redhat.com>
* src/vectors.S (restore_state): (see the change below 2001-07-03)
Make the code to keep SR IM bits from the ISR conditional on a CDL
interface so that it is selected on a per-platform or variant basis.
* cdl/hal_mips.cdl (CYGINT_HAL_MIPS_INTERRUPT_RETURN_KEEP_SR_IM):
New interface to control conditional code.
* include/hal_intr.h (HAL_ENABLE_INTERRUPTS): Make this (et al)
conditional on CYGHWR_HAL_INTERRUPT_ENABLE_DISABLE_RESTORE_DEFINED
so that the variant HAL can define these insead, in the usual
manner.
2001-07-20 Jonathan Larmour <jlarmour@redhat.com>
* src/redboot_linux_exec.c: Adjust below change by getting baud
rate, thus allowing for runtime baud rate changes, and no
dependency on platform CDL defines.
2001-07-19 Gary Thomas <gthomas@redhat.com>
* src/redboot_linux_exec.c: Define DEFAULT_BAUD. The supporting
CDL differs from platform to platform, so this define is used to
ameliorate the differences.
2001-07-17 David Woodhouse <dwmw2@redhat.com>
* src/redboot_linux_exec.c: Add environment stuff to the 'exec'
command, also make it use the entry point from the last 'load'
command if there is one.
Also add '-w' delay option.
2001-07-09 David Woodhouse <dwmw2@redhat.com>
* src/redboot_linux_exec.c: New 'exec' command for RedBoot, mostly
copied from the SH version, hacked to pass arguments in argc/argv
form as that seems to be what most Linux/MIPS kernels expect to
receive from PMON.
* cdl/hal_mips.cdl: Add necessary magic for the above.
2001-07-03 Hugo Tyson <hmt@redhat.com>
* src/vectors.S (restore_state): When restoring the CPU status
register right at the end of interrupt processing, keep the
current settings of the IM[7:0] bits within the status register.
Depending on platform, these may be used as interrupt masks, so if
an ISR or DSR masks interrupts they must be preserved. If they
are not used, then this does no harm.
#ifdef'd out for CYG_HAL_MIPS_R3900 anyway 'cos the TX39 does not
use these bits at all.
2001-06-27 Mark Salter <msalter@redhat.com>
* src/vectors.S (_start): Add code to switch from KSEG1 to KSEG0 if
CYGARC_START_FUNC_UNCACHED.
2001-06-27 Hugo Tyson <hmt@redhat.com>
* src/hal_misc.c: Include <cyg/hal/hal_if.h> for definition of
hal_ctrlc_isr() and hence warnings reduced.
2001-06-19 Mark Salter <msalter@redhat.com>
* include/hal_arch.h: Support saving/restoring CP0 registers for GDB.
* include/mips-stub.h (NUMREGS): Use different value for mips32.
2001-06-08 Jesper Skov <jskov@redhat.com>
* include/mips.inc (FUNC_START): Added .noreorder.
2001-06-05 Hugo Tyson <hmt@redhat.com>
* include/mips-stub.h: Configuration messing to avoid the need to
add a platform-specific clause for every new 32-as-64-to-GDB
target that we make. The header can now pick REGSIZE,
target_register_t and so on according to a generic define as well
as specific platform defs.
* cdl/hal_mips.cdl: Provide interface for the above, so targets
can implement it. CYGINT_HAL_MIPS_STUB_REPRESENT_32BIT_AS_64BIT
2001-02-27 Chris Morrow <cmorrow@YottaYotta.com>
* src/vectors.S (hal_zero_bss): Oops, allow for bss being multiple
of block size. And add delay slot.
2001-02-26 Chris Morrow <cmorrow@YottaYotta.com>
* src/vectors.S (hal_zero_bss): Implemented in assembler for speed.
* src/hal_misc.c (hal_zero_bss): Delete.
2001-02-15 Nick Garnett <nickg@cygnus.co.uk>
* src/hal_misc.c: Added option to call hal_ctrlc_isr() in default
ISR when in RedBoot.
2001-02-12 Nick Garnett <nickg@cygnus.co.uk>
* include/mips.inc: Added some extra CP0 register names.
2001-02-09 Jesper Skov <jskov@redhat.com>
* src/vectors.S: Small tweak of comments to work around tools problem
with mipsisa32 tools.
2001-01-31 Nick Garnett <nickg@cygnus.co.uk>
* include/mips-stub.h: Added prototypes for __is_bsp_syscall() and
hal_syscall_handler().
* include/hal_arch.h:
Reorganized HAL_SavedRegisters structure to work properly with a
64 bit processor. Fields are now correctly sized, and aligned on
the right boundaries.
* include/arch.inc:
Added option for variant and platform to supply extra bits to be
added to INITIAL_SR.
Reorganized register save area layout to match changes in
hal_arch.h.
Added macros sva, lva, mvatc0, mvafc0 to transfer 64 bit items to
and from memory/CP0 (*va* is used because most such values are
(virtual) addresses).
* src/vectors.S: Added use of *va* macros where appropriate.
* src/mips-stub.c: Added __is_bsp_syscall() function.
* src/hal_syscall.c: Added this file to support GNUPro system
calls in RedBoot.
* cdl/hal_mips.cdl: Added hal_syscall.c to compile list.
2001-01-26 Jesper Skov <jskov@redhat.com>
* include/hal_intr.h: Added extern for hal_delay_us.
2001-01-26 Jesper Skov <jskov@redhat.com>
* include/variant.inc: Make hal_intc_decode macro mask the cause
register with the status (interrupt mask) register.
2001-01-25 Jesper Skov <jskov@redhat.com>
* include/arch.inc: Allow hal_intc_decode to be defined by variant
or platform.
2000-12-06 Jesper Skov <jskov@redhat.com>
* include/hal_intr.h (HAL_DELAY_US): Added.
* src/hal_misc.c (hal_delay_us): Added. And fixed to work with an
incrementer that ticks at the pipeline clock rate.
* include/mips-stub.h: RM7000 is also a 64bit CPU.
2000-12-05 Jonathan Larmour <jlarmour@redhat.com>
* include/hal_cache.h: IWAY->_IWAY, DWAY->_DWAY for namespace
cleanliness
2000-12-05 Jesper Skov <jskov@redhat.com>

* src/hal_misc.c (cyg_hal_exception_handler): Undid below change.
* src/hal_misc.c (cyg_hal_exception_handler): Base vector
calculation on cause register, not the provided vector value.
2000-09-12 Jesper Skov <jskov@redhat.com>
* include/hal_intr.h: Added definition for decoded FPU
exceptions.
* src/hal_misc.c (cyg_hal_exception_handler): Decode FPU
exceptions.
2000-09-07 Jesper Skov <jskov@redhat.com>
* include/basetype.h: Removed change from yesterday.
* include/hal_intr.h (CYGNUM_HAL_EXCEPTION_FPU): Associated to FPE
exceptions.
2000-09-06 Jesper Skov <jskov@redhat.com>
* include/basetype.h: Override the alignment macros for the MIPS
architecture. The MIPS compiler only alows a maximum of 4 bytes
of alignment where as the default is 8
* include/hal_cache.h (_HAL_ASM_DCACHE_ALL_WAYS): Force d-cache
selection.
2000-09-01 Jonathan Larmour <jlarmour@redhat.com>
* include/mips-stub.h: No longer need to define
CYGARC_REGSIZE_DIFFERS_FROM_TARGET_REGISTER_T
(CYGARC_SIGN_EXTEND_REGISTERS):
* include/mips-stub.h: Change vr4300 register sizes to use 32-bit
target_register_t, and tell the generic stub to use sign extension.
Ditto for tx49
* include/hal_cache.h (_HAL_ASM_SET_MIPS_ISA): Don't use pasting
when it doesn't result in a preprocessing token. Just use string
concatenation.
2000-07-21 Drew Moseley <dmoseley@redhat.com>
* src/vectors.S: Only jump uncached to _start if
CYGARC_START_FUNC_UNCACHED is defined.
2000-07-20 Drew Moseley <dmoseley@redhat.com>
* include/mips-stub.h: Define CYGARC_REGSIZE_DIFFERS_FROM_TARGET_REGISTER_T
for the MIPS32 targets since GDB needs 64 bit registers regardless of
what size we are really storing.
2000-07-19 Drew Moseley <dmoseley@redhat.com>
* include/mips-stub.h (CYGARC_SIGN_EXTEND_REGISTERS): Make sure
the stub sign-extends the registers before returning them to GDB.
2000-07-14 Drew Moseley <dmoseley@redhat.com>

corruption. Added breakpoint support in the HAL.
2000-07-14 Drew Moseley <dmoseley@redhat.com>
* include/arch.inc: Support for mips3264.
* include/mips-stub.h: Ditto.
2000-06-21 Nick Garnett <nickg@cygnus.co.uk>
* src/mips-stub.c: Removed use of CYG_LABEL_NAME() and added

2000-06-08 Jesper Skov <jskov@redhat.com>
* src/hal_misc.c (hal_arch_default_isr): Removed what's now a
generic C-c check in the common HAL.

* src/mipsfp.c:
Support FPU double-LE layout in BE mode.
2000-05-24 Jesper Skov <jskov@redhat.com>
* src/mipsfp.c: Also handle doubles in 32bit FPU mode.
2000-05-23 Jesper Skov <jskov@redhat.com>
* include/arch.inc:
* src/vectors.S:
Made exception return safe.
2000-05-22 Jesper Skov <jskov@redhat.com>
* src/vectors.S: Call CTRLC init after stub initialization.
* cdl/hal_mips.cdl: Only include CTRLC support if not prevented
by platform.
* include/hal_cache.h: When using 'cache' instruction, hit all
ways, not only way0.
2000-05-18 Jesper Skov <jskov@redhat.com>
* include/hal_io.h: Allow platforms to override IO macro
definitions.
2000-05-16 Jesper Skov <jskov@redhat.com>
* include/hal_intr.h:
* src/vectors.S:
Filter 'break 0x7' (GCC division-by-zero) exceptions out into a
new vector.
Fix typo.
2000-05-15 Jesper Skov <jskov@redhat.com>

2000-05-10 Jesper Skov <jskov@redhat.com>
* include/arch.inc: Force assembler into MIPS3 mode before using
eret.
* include/basetype.h: Fix comments.
2000-03-20 Jonathan Larmour <jlarmour@redhat.co.uk>
* include/mips-stub.h: Make C++ safe
* include/hal_cache.h (_hal_asm_mips_cpp_stringize): Add as a separate
macro because the compiler has got more picky
2000-03-16 Jonathan Larmour <jlarmour@redhat.co.uk>
* src/vectors.S (_start): Set return address to 0 and unconditionally
jump to cyg_start, so that GDB doesn't get confused with backtraces
2000-03-13 Nick Garnett <nickg@cygnus.co.uk>
* src/context.S :
Added jmpbuf_regsize to insulate jumb buffer from changes in
mips_regsize. This will need extra work if we go to a full 64 bit
variant, but for now is the simplest solution to this problem.
2000-02-25 Jonathan Larmour <jlarmour@redhat.co.uk>
* include/arch.inc: Add lpc and spc macros to save and restore PC
* src/context.S (hal_thread_switch_context): Restore RA into PC
location in context so that thread debugging works
2000-02-23 Jonathan Larmour <jlarmour@redhat.co.uk>
* src/hal_misc.c (hal_idle_thread_action):
CYG_HAL_MIPS_SIM -> CYGPKG_HAL_MIPS_SIM
CYG_HAL_MIPS_JMR3904 -> CYGPKG_HAL_MIPS_TX39_JMR3904
* include/arch.inc: CYG_HAL_MIPS_SIM -> CYGPKG_HAL_MIPS_SIM
2000-02-16 Jesper Skov <jskov@redhat.com>
* cdl/hal_mips.cdl: removed fix me.
2000-01-14 Nick Garnett <nickg@cygnus.co.uk>
* include/hal_arch.h:
* include/arch.inc:
* src/vectors.S:
* src/context.S:
Several fixes to allow the GPRs to be saved
and restored as 64 bit values on some architectures. This is not
full 64 bit support since it only covers the GPRs, HI and LO,
there is more to be done in the CP0 registers (however it is a
start).
1999-12-21 Jonathan Larmour <jlarmour@cygnus.co.uk>
* src/vectors.S (__default_exception_vsr): Rename
CYG_HAL_USE_ROM_MONITOR_CYGMON -> CYGSEM_HAL_USE_ROM_MONITOR_CygMon
Rename CYG_HAL_ROM_MONITOR -> CYGSEM_HAL_ROM_MONITOR
* src/hal_misc.c (hal_default_isr): Rename
CYG_HAL_USE_ROM_MONITOR_CYGMON ->
CYGSEM_HAL_USE_ROM_MONITOR_CygMon
* include/arch.inc: Rename CYG_HAL_USE_ROM_MONITOR ->
CYGSEM_HAL_USE_ROM_MONITOR
1999-12-20 John Dallaway <jld@cygnus.co.uk>
* cdl/hal_mips.cdl:
Fix syntax error.
1999-12-17 Jonathan Larmour <jlarmour@cygnus.co.uk>
* src/mipsfp.c (flt2reg): New inline function to convert between
float union and register type
(reg2flt): Likewise in reverse
(cyg_hal_mips_process_fpe): Handle endianness correctly using the above
functions. Avoid possible aliasing problems with the compiler. Ensure
values are zeroed with the correct sign. Check for denormalized operands
for all remaining FPU opcodes.
* src/hal_misc.c (cyg_hal_exception_handler): Allow handling of
unimplemented operation FPU exceptions to be configurable
* include/pkgconf/hal_mips.h: Provide
CYGSEM_HAL_MIPS_EMULATE_UNIMPLEMENTED_FPU_OPS to do this
* cdl/hal_mips.cdl: Likewise
All the above required for cases 102817 and 102820
1999-12-15 Jonathan Larmour <jlarmour@cygnus.co.uk>
* include/hal_intr.h (CYGNUM_HAL_EXCEPTION_COUNT): Ensure you can
handle FPU exceptions if present
Reported in case 102817
1999-12-02 John Dallaway <jld@cygnus.co.uk>
* cdl/hal_mips.cdl:
Use the <PACKAGE> token in custom rules.
1999-12-01 John Dallaway <jld@cygnus.co.uk>
* cdl/hal_mips.cdl:
Use the <PREFIX> token in custom rules.
1999-11-04 John Dallaway <jld@cygnus.co.uk>
* cdl/hal_mips.cdl:
Output custom rule dependency information to .deps files in
the current directory.
Dispense with the need to create a 'src' sub-directory.
1999-11-04 Nick Garnett <nickg@cygnus.co.uk>
* src/vectors.S: Added code in reset vector to reset the config0
register to a known state. This is because on some MIPS variants
the K0 field comes up in an undefined state.
[Later] Moved this code to just work in the case of a cold boot.
NMIs and warm boots should leave it as it was.
1999-11-02 Jesper Skov <jskov@cygnus.co.uk>
* cdl/hal_mips.cdl: Added.
1999-10-29 Nick Garnett <nickg@cygnus.co.uk>
* include/pkgconf/hal_mips.h: Added condition to set a
MIPS-private option (CYGDBG_HAL_MIPS_DEBUG_GDB_CTRLC_SUPPORT) if
either CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT or
CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT are defined. In the MIPS HAL
these are implmented with the same code.
* src/hal_misc.c: Changed CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT to
CYGDBG_HAL_MIPS_DEBUG_GDB_CTRLC_SUPPORT.
* src/vectors.S: Space for old SP after switching to interrupt
stack must be 8 bytes to preserve alignment of SP. Otherwise any
nested interrupts or exceptions will get an address error
exception if the FP regs are saved, which then recurses.
Changed CYGDBG_HAL_DEBUG_GDB_CTRLC_SUPPORT to
CYGDBG_HAL_MIPS_DEBUG_GDB_CTRLC_SUPPORT.
* src/mips-stub.c (__is_breakpoint_function): Fixed comparison
between PC register and label. On 64 bit CPUs these are both 32
bit values in 64 bit types, but the way that they are generated,
the PC is zero extended and the label is sign extended. This
caused them to always differ. Fixed by casting label to unsigned
long before widening.
1999-10-22 Nick Garnett <nickg@cygnus.co.uk>
* src/vectors.S: Replaced ifdef with call to hal_intc_translate
macro so the behaviour here may be customized by variant or
platform HALs.
* include/arch.inc: Added default implementations of
hal_intc_translate macro.
1999-10-05 Nick Garnett <nickg@cygnus.co.uk>
* include/basetype.h: Made definition of CYG_BYTEORDER dependent
on definition of CYGPKG_HAL_MIPS_[L|M]SBFIRST.
1999-09-17 Jonathan Larmour <jlarmour@cygnus.co.uk>
* src/vectors.S (__default_exception_vsr):
Rename exception_handler()->cyg_hal_exception_handler()
After all, we will just do a jump rather than a jal into
cyg_hal_exception_handler()
(restore_state): Make the change below (by Hugo) be conditional
on CYG_HAL_USE_ROM_MONITOR_CYGMON.
Add explanatory comment about the additions for Cygmon
* src/hal_misc.c (hal_default_isr): Use new format HAL_DIAG_IRQ_CHECK()
and check return code is negative; if so, return
(cyg_hal_exception_handler): Rename from exception_handler()
Now return cyg_uint32, but default to returning 0 always
1999-09-16 Hugo Tyson <hmt@cygnus.co.uk>
This set of changes with matching ones in jmr3904 comes from Mark
Salter's work to make jmr3904 CygMon talk Ethernet.
* src/vectors.S (restore_state): Call CygMon for exceptions or
unhandled interrupts if CYG_HAL_USE_ROM_MONITOR. This is why the
return value from the ISR is preserved. Don't fully understand
this.
* src/hal_misc.c (hal_default_isr): Call into hal_diag via
HAL_DIAG_IRQ_CHECK if it's defined and CYG_HAL_USE_ROM_MONITOR.
This lets CygMon check for network interrupts &c.
1999-09-09 Nick Garnett <nickg@cygnus.co.uk>
* include/arch.inc:
Moved code to initialize cache out to variant header since it is
variant specific.
1999-09-08 Jonathan Larmour <jlarmour@cygnus.co.uk>
* src/hal_misc.c (exception_handler): Catch exceptions that come from
within GDB stubs and return if that's what the stubs intend
1999-08-19 Nick Garnett <nickg@cygnus.co.uk>
* include/hal_io.h: Added include of plf_io.h.
1999-08-10 Jonathan Larmour <jlarmour@cygnus.co.uk>
* src/mipsfp.c (cyg_hal_mips_process_fpe): CYG_REPORT_FUNCNAMETYPE()
must be first in a C file
1999-07-15 Jonathan Larmour <jlarmour@cygnus.co.uk>

__default_exception_vsr to re-enable nested exceptions.
* src/mips-stub.c: Use _registers[X] rather that register[X] for
accessing CPU registers, since the former may point to per-thread
register sets while the latter only refers to the current trap
register set.
* include/arch.inc: Added hal_cpu_except_enable macro to
(re-)enable exception processing and disable interrupts. This is
necessary if we are to allow nested exceptions (like breakpoints

disable kseg0 caching in config0 register.
* include/hal_cache.h: Moved dummy addresses used in index

register.
* src/vectors.S: Modified hal_interrupt_stack_call_pending_DSRs()
to also call DSRs with interrupts enabled. Returns interrupt state
to original value when finished.

allow it to be defined elsewhere. Added default versions of diag
macros.

Removed interrupt enable/disables in interrupt processing since we
can now go through a thread switch with interrupts disabled.
Ifdeffed ISR tables so they can be defined elsewhere.
Added implementation of hal_interrupt_stack_call_pending_DSRs.
Added calls to implementation and platform init routines.
* src/hal_misc.c: Many changes to hal_idle_thread_action() to

Added implementations of HAL_INTERRUPT_ACKNOWLEDGE() and
HAL_INTERRUPT_SET_LEVEL().
1998-10-13 Jesper Skov <jskov@cygnus.co.uk>
* src/hal_misc.c: Use GDB array rather than HAL_SavedRegisters
structure. Rely on generic stub to pack/unpack the array.
* include/hal_arch.h (HAL_GET_GDB_REGISTERS,
HAL_SET_GDB_REGISTERS): get/set full register set.
1998-10-13 Jesper Skov <jskov@cygnus.co.uk>
* include/mips-stub.h: Moved first use of regnames below
definition.
Sun Sep 27 12:17:42 1998 Jesper Skov <jskov@cygnus.co.uk>

1998-09-26 Nick Garnett <nickg@cygnus.co.uk>
* include/hal_cache.h:
Cleaned up some compilation errors.
Tue Sep 15 19:13:43 1998 David Moore <dsm@keema.cygnus.co.uk>
* src/vectors.S: Cleaned up comments.
1998-09-15 Nick Garnett <nickg@cygnus.co.uk>
* include/hal_arch.h (HAL_GET_GDB_REGISTERS):
Initialized R30 to a copy of SP to avoid GDB making bogus memory
references.
* src/hal_misc.c:
Added support for Ctrl-C processing when running under Cygmon.
Fixed a compiler warning.
1998-09-14 Bart Veer <bartv@cygnus.co.uk>
* src/PKGconf.mak:
Made vectors.o dependent on the various files that can contain
makefile variables or rules. This is needed after changes to
pkgconf.tcl for PRs 17195 and 17286.
Mon Sep 14 11:10:20 1998 Jesper Skov <jskov@lassi.cygnus.co.uk>
PR 17230
* src/vectors.S: Replaced CYGIMP_KERNEL_INTERRUPTS_CHAIN with new
CYGIMP_HAL_COMMON_INTERRUPTS_CHAIN.
1998-09-14 Nick Garnett <nickg@cygnus.co.uk>
PR 17230
* include/hal_intr.h:
Added HAL_TRANSLATE_VECTOR() to translate a supplied vector number
into one that can be used in the HAL. Added calls to it in
HAL_INTERRUPT_ATTACH() and HAL_INTERRUPT_DETACH().
1998-09-12 Bart Veer <bartv@cygnus.co.uk>
* include/pkgconf/hal_tx39.h:
Added missing descriptions (PR 17184)
* src/vectors.S:
<pkgconf/kernel.h> was being included without properly checking
that the kernel package was enabled.

Sort out exception handling options (PR 16953)
1998-09-11 Nick Garnett <nickg@cygnus.co.uk>
PR 17230
* src/vectors.S (__default_interrupt_vsr):
Modified interrupt decode code to preserve raising interrupt
number to pass to ISR, even when using chained interrupts.
1998-09-03 Bart Veer <bartv@cygnus.co.uk>
* src/mips-stub.c:
Fixed type in config option name.
1998-09-02 Bart Veer <bartv@cygnus.co.uk>
* include/pkgconf/hal_tx39.h:
New header file for architecture-specific configuration options
* tests/PKGconf.mak:
* src/PKGconf.mak:
Sort out package naming conventions.
Tue Sep 1 19:26:45 1998 Hugo Tyson <hmt@cygnus.co.uk>
* src/hal_misc.c:
Use CYGDBG_INFRA_DIAG_USE_DEVICE (from infra.h) instead of
CYG_DIAG_USE_DEVICE (badly named, from kernel.h).
1998-09-01 Nick Garnett <nickg@cygnus.co.uk>
* include/hal_intr.h:
Added CYG_EXCEPTION_COUNT.
1998-08-28 Bart Veer <bartv@cygnus.co.uk>
* src/vectors.S, src/context.S, src/hal_misc.c, src/mips-stub.c:
Updated for new kernel configuration option symbol names
Fri Aug 28 10:01:24 1998 Jonathan Larmour <jlarmour@cygnus.co.uk>
* src/hal_misc.c:
Rename __main() to cyg_hal_invoke_constructors() to prevent the
implied link with things called, or related to main(). Remove static
initialised variable as we can now guarantee it is only called
once.
* src/vectors.S:
Instead of calling main(), call cyg_start() which lives in the infra
package.
Explicitly invoke constructors as it isn't done magically for us
any more, now that main() is no longer used.
1998-08-25 Nick Garnett <nickg@cygnus.co.uk>
* src/vectors.S:
Now pass pointer to saved registers as third argument to
interrupt_end().
* include/hal_arch.h:
Added macros to support GDB.
Tue Aug 25 02:33:59 1998 Jonathan Larmour <jlarmour@cygnus.co.uk>
* include/mips_stub.h, src/hal_misc.c:
Add void to prototypes and typedefs that want it to silence warnings
1998-08-21 Nick Garnett <nickg@cygnus.co.uk>
* include/hal_cache.h:
Now includes cyg_type.h rather than ktypes.h.
1998-08-18 Nick Garnett <nickg@cygnus.co.uk>
* src/context.S:
* include/hal_arch.h:
* include/hal_io.h:
* include/hal_intr.h:
Now uses cyg_type.h rather than ktypes.h.
* src/hal_misc.c:
* src/vectors.S:
Now uses hal.h rather than kernel.h.
1998-07-23 Nick Garnett <nickg@cygnus.co.uk>
* include/hal_intr.h: Fixed some issues raised bt code review.
* src/context.S:
* include/hal_arch.h: Fixed some typos raised by code review.
* include/hal_intr.h (HAL_INTERRUPT_MASK):
* src/vectors.S (hal_interrupt_level): Added hal_interrupt_level
to allow for interaction between HAL_INTERRUPT_UNMASK() and
HAL_INTERRUPT_SET_LEVEL().
