|
|
* src/powerpc.ld:
|
| 4 |
|
|
Added .eh_frame to data section. This is a stopgap fix to allow
|
| 5 |
|
|
C++ programs that define exceptions to link and run. It does not
|
| 6 |
|
|
allow them to actually throw exceptions, since that depends on
|
| 7 |
|
|
compiler changes that have not been made. Further, more
|
| 8 |
|
|
far-reaching, linker script changes will also be needs when that
|
| 9 |
|
|
happens.
|
| 10 |
|
|
Added libsupc++.a to GROUP() directive for GCC versions later than
|
| 11 |
|
|
3.0.

|
|
|
| 19 |
|
|
* src/vectors.S:
|
| 20 |
|
|
* cdl/hal_powerpc.cdl: Add option to allow ROM code to simply
|
| 21 |
|
|
jump to the startup code, instead of using an absolute address.
|
| 22 |
|
|
|
| 23 |
|
|
2002-11-14 Gary Thomas
|
| 24 |
|
|
|
| 25 |
|
|
* src/vectors.S: Provide pointer to saved registers on interrupt.
|
| 26 |
|
|
This is necessary for profiling support.
|
| 27 |
|
|
|
| 28 |
|
|
2002-11-13 Gary Thomas
|
| 29 |
|
|
|
| 30 |
|
|
* src/hal_misc.c (hal_enable_caches): Support new CDL options for
|
| 31 |
|
|
how [mode] to enable DATA cache.

2002-08-05 Bob Koninckx
|
| 35 |
|
|
|
| 36 |
|
|
* include/arch.inc: hal_fpu_load regs was not loading registers!
|
| 37 |
|
|
|
| 38 |
|
|
2002-08-01 Gary Thomas
|

2002-04-29 Jonathan Larmour
|
| 44 |
|
|
|
| 45 |
|
|
* src/vectors.S:
|
| 46 |
|
|
Don't use .file as it can confuse debugging since the .file
|
| 47 |
|
|
doesn't contain the path and therefore the debugger will never
|
| 48 |
|
|
know where it lives! This conflicts with using -Wa,--gstabs.
|

|
2002-04-25 Jonathan Larmour
|
| 51 |
|
|
|
| 52 |
|
|
* src/ppc_stub.c (__computeSignal): Only handle ITLB/DTLB MISS if
|
| 53 |
|
|
defined by platform.

|
|
|
| 58 |
|
|
* include/hal_arch.h (HAL_SavedRegisters): Add FP regs.
|
| 59 |
|
|
* include/arch.inc: Add FPU register names.
|
| 60 |
|
|
Implement hal_fpu_save and hal_fpu_load.
|
| 61 |
|
|
* src/context.S: save/restore FP regs.
|
| 62 |
|
|
* src/hal_mk_defs.c (main): Export CYGARC_JMPBUF_F* for FPU regs.
|
| 63 |
|
|
* src/ppc_stub.c (__computeSignal): SW_EMUL is support by 5xx.
|
| 64 |
|
|
ITLB and DTLB MISS only supported by 8xx.
|
| 65 |
|
|
* cdl/hal_powerpc.cdl (CYGHWR_HAL_POWERPC_VECTOR_BASE): Take
|
| 66 |
|
|
CYGHWR_HAL_POWERPC_FORCE_VECTOR_BASE_LOW into account.
|
| 67 |
|
|
|
| 68 |

|
2002-04-11 Gary Thomas
|
| 69 |
|
|
|
| 70 |
|
|
* src/hal_misc.c (hal_enable_caches): Chance cache handling & setup to
|
| 71 |
|
|
be controlled by common CDL (like other platforms/architectures).
|
| 72 |
|
|
|
| 73 |
|
|
* src/hal_intr.c (hal_delay_us): Didn't work if there are less than
|
| 74 |
|
|
one decrementer tick per micro-second. Used a calculation that seems
|
| 75 |
|
|
to work no matter how the decrementer is configured.
|
| 76 |
|
|
|
| 77 |
|
|
2002-04-08 Gary Thomas
|
| 78 |
|
|
|
| 79 |
|
|
* src/vectors.S (_hal_hardware_init_done): Can't copy vectors until
|
| 80 |
|
|
DRAM is setup (like the comment said all along).
|
| 81 |
|
|
|
| 82 |
|
|
2002-03-08 Gary Thomas
|
| 83 |
|
|
|
| 84 |
|
|
* src/vectors.S (_hal_hardware_init_done): New label - used by

| 85 |
|
|
ROMRAM code to figure out relative addressing.
|
| 86 |
|
|
|
| 87 |
|
|
2002-01-23 Gary Thomas

|
|
|

|
|
2001-11-16 Nick Garnett
|
| 92 |
|
|
|
| 93 |
|
|
* include/hal_arch.h (HAL_MSBIT_INDEX): Fixed this macro so that
|
| 94 |
|
|
it actually works!
|
| 95 |
|
|
|
| 96 |
|
|
2001-11-15 Jesper Skov
|
| 97 |
|
|
|
| 98 |
|
|
* src/hal_misc.c (hal_arch_default_isr): Added return
|
| 99 |
|
|
statement (found by Christoph Csebits).
|
| 100 |
|
|
|
| 101 |
|
|
2001-02-23 Jesper Skov
|
| 102 |
|
|
|
| 103 |
|
|
* src/powerpc.ld: Added .2ram section matching to .data section.
|
| 104 |
|
|
|
| 105 |
|
|
2001-02-05 Jesper Skov
|
| 106 |
|
|
|
| 107 |
|
|
* src/ppc_stub.c (__computeSignal): Hack to allow thread debugging
|
| 108 |
|
|
on 40x cores.
|
| 109 |
|
|
|
| 110 |
|
|
2001-01-24 Jesper Skov
|
| 111 |
|
|
|
| 112 |
|
|
* src/powerpc.ld: Added .sdata to .sdata pattern.
|
| 113 |
|
|
|
| 114 |
|
|
2001-01-16 Gary Thomas
|
| 115 |
|
|
|
| 116 |
|
|
* src/vectors.S (_start): Set up IRQ environment _before_ calling
|
| 117 |
|
|
constructors - since they may need it to work.
|
| 118 |
|
|
|
| 119 |
|
|
2001-01-15 Gary Thomas
|
| 120 |
|
|
|
| 121 |
|
|
* src/ppc_stub.c: Define new method for achieving single stepping
|
| 122 |
|
|
when processor (like 40x) does not support it in hardware. This
|
| 123 |
|
|
method will be invoked if the variant or plaform define the
|
| 124 |
|
|
symbol CYGNUM_HAL_NO_VECTOR_TRACE.
|
| 125 |
|
|
|
| 126 |
|
|
2001-01-03 Gary Thomas
|
| 127 |
|
|
|
| 128 |
|
|
* src/hal_intr.c (hal_delay_us): Fix some problems - didn't
|
| 129 |
|
|
always work properly, especially on fast processors.
|
| 130 |
|
|
|
| 131 |
|
|
2000-11-21 Gary Thomas
|
| 132 |
|
|
|
| 133 |
|
|
* src/vectors.S (rom_vectors): Special handling when vectors
|
| 134 |
|
|
can't be easily aligned, etc. (Work around messy hardware).
|
| 135 |
|
|
|
| 136 |
|
|
2000-11-04 Gary Thomas
|
| 137 |
|
|
|
| 138 |
|
|
* src/vectors.S: Minor changes in support of PPC40x. This
|
| 139 |
|
|
platform has no cache control - if the MMU is on, it's on.
|
| 140 |
|
|
This causes some interesting cache coherency problems in the
|
| 141 |
|
|
interrupt/exception handlers. Note: it may be possible to
|
| 142 |
|
|
overcome this by use of the DCCR register (untested).
|
| 143 |
|
|
|
| 144 |
|
|
* src/powerpc.ld: Fix problems with 'sbss6', etc.
|
| 145 |
|
|
|
| 146 |
|
|
* src/hal_mk_defs.c: Use variant/platform macros for additional
|
| 147 |
|
|
symbols, rather than direcly polluting this file.
|
| 148 |
|
|
|
| 149 |
|
|
* include/hal_intr.h: Allow variant/platform to define clock
|
| 150 |
|
|
setup (since the 40x does not have a decrementer!)
|
| 151 |
|
|
|
| 152 |
|
|
2000-10-31 Jonathan Larmour
|
| 153 |
|
|
|
| 154 |
|
|
* src/powerpc.ld: Use .sdata.* rather than .sdata* so that .sdata2
|
| 155 |
|
|
doesn't get matched so that the linker script symbols are still valid.
|
| 156 |
|
|
Ditto for .sbss*.
|
| 157 |
|
|
|
| 158 |
|
|
2000-10-24 Jonathan Larmour
|
| 159 |
|
|
|
| 160 |
|
|
* src/powerpc.ld: Match multiple sections where relevant (.bss*,
|
| 161 |
|
|
.sbss*, .sdata*, etc.)
|
| 162 |
|
|
|
| 163 |
|
|

|
| 164 |
|

|
| 170 |
|
|
* include/hal_intr.h (HAL_DELAY_US): New function.
|
| 171 |
|
|
|

|
|
2000-10-16 Jonathan Larmour
|
| 173 |
|

|
| 174 |
|
|
* include/hal_arch.h (CYGARC_JMP_BUF_SIZE): Define hal_jmp_buf
|
| 175 |
|
|

|
|
|
| 177 |
|

2000-08-15 Gary Thomas
|
| 178 |
|
|
|

|
|
CYG_LABEL_NAME() and added underscore to _breakinst.
|
| 190 |
|
|
|
| 191 |
|
|
* src/powerpc.ld:
|
| 192 |
|
|
Switched to new table definition mechanism.
|
| 193 |
|
|
|
| 194 |
|
|
* include/basetype.h: Removed definition of CYG_LABEL_NAME().

|
|
| 216 |
|
|
* src/hal_misc.c (hal_idle_thread_action): Moved some of the code
|
| 217 |

* include/hal_intr.h (CYGNUM_HAL_EXCEPTION_DATA_ACCESS): Define

|
|
this for handling MACHINE_CHECK if an MPC860 - it never generates
|
| 472 |
|

ISI nor DSI exceptions, only machine check. This allows libc to

used to setup whatever is necessary to handle interrupts.
|
| 490 |
|
|
Add basic "wiring" of CPM to SIU interrupts.
|
| 491 |
|
|

* src/hal_misc.c (cyg_hal_exception_handler): If the decrementer
|
| 502 |
|
|
has underflowed when we are returning from an exception, then we
|
| 503 |
|
|
reset it here; this is harmless if all is well, and required if
|
| 504 |
|
|
the QUICC-equipped MPC860 is getting confused about interrupts
|
| 505 |
|

following an exception. Only in QUICC configurations.

when we see a breakpoint, if RAM start and RAM-based vectors for

|
|
the stub. Rather than using a direct jump, instead skip copying

| 512 |
|
|
the program exception vectors - leave the stub's vec in place.
|
| 513 |
|
|
Controlled by CYGPRI_STUBROM_HAS_RAM_VECTORS, which varies from

platform to platform.

reorganized and renamed into the FADS component.

debugging for interrupt/clock of the MBX860/PPC860; normally

|
|
disabled, so no effect on code.
