* cdl/hal_frv.cdl: Eliminate some warnings. [ Bugzilla 1001083 ]

|

|
|
|
| 8 |
|
|
* src/vectors.S (reset_vector): Add some debug-only led setting code.
|
| 9 |
|
|
* src/redboot_linux_exec.c: Rename auto-variable for clarity.
|
| 10 |
|
|
* include/fr-v.h: Add defines for baud clock prescaler.
|
| 11 |
|
|
* src/vectors.S: Fix check for PDM bits in potential resume.
|
| 12 |
|
|
* src/vectors.S: Handle resume from sleep modes.
|
| 13 |
|
|
* src/redboot_linux_exec.c: Fix argv parsing for exec() command.
|
| 14 |
|
|
* include/hal_diag.h src/hal_diag.c: Move support for the built-in
|
| 15 |
|
|
16550-like chips found on all known implementations of these CPUs
|
| 16 |
|
|
into the arch directory to avoid duplication.
|
| 17 |
|
|
* include/fr400.h include/fr500.h include/fr-v.h: Likewise many
|
| 18 |
|
|
other register definitions.
|
| 19 |
|
|
* src/hal_breakpoint.c: Likewise breakpoint/watchpoint stuff.
|
| 20 |
|
|
* cdl/hal_frv.cdl: Changes to reflect the above.
|
| 21 |
|
|
* src/vectors.S: Install exception vectors if not defined
|
| 22 |
|
|
CYGSEM_HAL_USE_ROM_MONITOR. This way, syscalls and GDB work
|
| 23 |
|
|
in RAM RedBoot.
|
| 24 |
|
|
* cdl/hal_frv.cdl, src/redboot_linux_exec.c: Exec command.
|
| 25 |
|
|
* src/vectors.S, src/context.S, include/hal_arch.h: Save extra GP
|
| 26 |
|
|
and FP regs only when they're actually available on this CPU, if
|
| 27 |
|
|
multiple CPUs are supported.
|
| 28 |
|
|
* cdl/hal_frv.cdl: Disable use of break insn for trap. Remove
|
| 29 |
|
|
seemingly unnecessary option for hardware debugging.
|
| 30 |
|
|
* include/hal_arch.h: Add _PSR_CM bit. It's not always hardwired.
|
| 31 |
|
|
* src/hal_mk_defs.c: Ditto. Rename _HAL_THREAD_INIT_CONTEXT
|
| 32 |
|
|
* src/vectors.S: Some ifdef cleanup, enable _PSR_CM
|
| 33 |

|
| 35 |
|
|
|
| 36 |
|
|
* cdl/hal_frv.cdl :
|
| 37 |
|
|
Invoke tail with stricter syntax that works in latest coreutils.
|
| 38 |
|
|
|
| 39 |
|
|
2003-04-10 Nick Garnett
|
| 40 |
|
|
|
| 41 |
|
|
* src/frv.ld:
|
| 42 |
|
|
Added .eh_frame to data section. This is a stopgap fix to allow
|
| 43 |
|
|
C++ programs that define exceptions to link and run. It does not
|
| 44 |
|
|
allow them to actually throw exceptions, since that depends on
|
| 45 |
|
|
compiler changes that have not been made. Further, more
|
| 46 |
|
|
far-reaching, linker script changes will also be needs when that
|
| 47 |
|
|
happens.
|
| 48 |
|
|
Added libsupc++.a to GROUP() directive for GCC versions later than
|
| 49 |
|
|
3.0.

|
| 52 |
|
|
|
| 53 |
|
|
* src/hal_syscall.c (hal_syscall_handler): Let generic syscall code
|
| 54 |
|
|
handle exit.
|
| 55 |
|
|
|
| 56 |
|
|
2002-04-15 Jonathan Larmour
|
| 57 |
|
|
|
| 58 |
|
|
* src/hal_syscall.c (hal_syscall_handler): Add extra sig argument to
|
| 59 |
|
|
__do_syscall.
|
| 60 |
|
|
|
| 61 |
|
|
2001-12-10 Richard Sandiford
|
| 62 |
|
|
|
| 63 |
|
|
* src/vectors.S (save_state): Remove unnecessary DDR diddling when
|
| 64 |
|
|
handling breaks. Use BPCSR rather than BPCSR-4 as the break address.
|
| 65 |
|
|
(restore_state): Take two new arguments: the register that the
|
| 66 |
|
|
PC should be loaded into, and the argument to the rett instruction.
|
| 67 |
|
|
(_break): If handling a break instruction, return to the following
|
| 68 |
|
|
instruction using a normal "ret". Ignore other kinds of break if
|
| 69 |
|
|
they were triggered when traps were disabled; assume that an
|
| 70 |
|
|
interrupt or exception handler has triggered a stack watchpoint
|
| 71 |
|
|
accidentally. Correct GP calculation. Return using "rett #1"
|
| 72 |
|
|
rather than "rett #0".
|

|
| 75 |
|
|
|
| 76 |
|
|
* src/vectors.S (_vectors): if defined(CYGPKG_HAL_FRV_FRV400) &&
|
| 77 |
|
|
defined(CYGDBG_HAL_DEBUG_GDB_INCLUDE_STUBS), add macro break_VSR
|
| 78 |
|
|
to create a VSR entry which leaps to _break; rearrange the
|
| 79 |
|
|
initialization of the VSR table so that the counts are correct;
|
| 80 |
|
|
use break_VSR in slot 255; define _break which calls break_handler()
|
| 81 |
|
|
much akin to exception handler().
|
| 82 |
|
|
|
| 83 |
|
|
Note that there is no need to define CYGSEM_HAL_FRV_HW_DEBUG for
|
| 84 |
|
|
the FRV_FRV400 target; while we do use Hardware Debug, we don't
|
| 85 |
|
|
use *that* sort of hardware debug, specifically we do not use
|
| 86 |
|
|
hardware single-step, because it breaks as soon as we exit debug
|
| 87 |
|
|
mode, ie whilst we are still within the stub. But vectors.S does
|
| 88 |
|
|
the same tidy-up of machine state, conditioned on FVR400 instead.

|
| 91 |
|
|
|
| 92 |
|
|
* src/frv_stub.c: Slight cleanup - only need |VLIW|+1 possible
|
| 93 |
|
|
breakpoint locations.
|
| 94 |
|
|
|
| 95 |
|
|
2001-10-16 Gary Thomas
|
| 96 |
|
|
|
| 97 |
|
|
* src/vectors.S (_exception_return): Remove *bad* workaround code
|
| 98 |
|
|
now that single step VLIW works properly.
|
| 99 |
|
|
|
| 100 |
|
|
* src/frv_stub.c (__clear_single_step):
|
| 101 |
|
|
(__single_step): Restructure to support VLIW sequences.
|
| 102 |
|

|
2001-10-15 Gary Thomas
|
| 104 |
|
|
|
| 105 |
|
|
* include/hal_arch.h: Remove [bogus] CYG_HAL_TABLE macros since
|
| 106 |
|
|
the common ones work fine on this architecture.
|
| 107 |
|
|
|
| 108 |
|
|
* src/vectors.S:
|
| 109 |
|
|
* src/frv_stub.c:
|
| 110 |
|
|
* cdl/hal_frv.cdl: Add CDL to describe various [hardware] debug
|
| 111 |
|
|
options.
|
| 112 |
|
|
|
| 113 |
|
|
2001-10-01 Gary Thomas
|
| 114 |
|
|
|
| 115 |
|
|
* src/vectors.S: [FRV400] can't return from exception to a packed
|
| 116 |
|
|
instruction - this yields illegal instruction.
|
| 117 |
|
|
|
| 118 |
