* cdl/hal_arm.cdl: Merge goals for CYGHWR_THUMB and
CYGBLD_ARM_ENABLE_THUMB_INTERWORK to allow selective application
of CDL solutions within the eCos Configuration Tool.

a global associated with code is defined. Otherwise objdump

Fix thinko in last checkin.

nickg — Mon, 09 Feb 2009 15:34:49 +0000

* src/vectors.S (start): The loop to initialize BSS was using a
BLS to terminate. This caused an extra zero to be stored beyond
the end of __bss_end. Usually this is benign, but when __bss_end
is at the very top of RAM, and the hardware generates an exception
for illegal accesses, this can crash the program before it even
starts. The fix is to use a BLT instructions which will terminate
the loop 1 word earlier.

* src/arm.ld: Discard C++ EH-related sections when we can't

jlarmour — Tue, 11 Nov 2008 04:28:45 +0000

* src/arm.ld: Discard C++ EH-related sections when we can't
possibly support C++ EH (no CYGPKG_LIBSTDCXX).

* src/hal_mk_defs.c: Also export HAL_BREAKINST_THUMB and
HAL_BREAKINST_ARM to asm.
* src/arm.ld: Revise alignment yet further. Maintain ALIGN_LMA
at original value, but define alignment for use in compliance
with AAPCS. Expand explanatory comments.
(SECTION_text): Comply with AAPCS alignment when inserting
.ARM.extab and .ARM.exidx.

* src/arm.ld: Rework alignment further to improve backward
compatibility. Improve commenting on alignment issues.

* src/arm.ld: We need to be double-word aligned sometimes, so align
LMA the same way too.

* cdl/hal_arm.cdl (CYGBLD_HAL_ARM_EABI): EABI has a different C++
EH implementation, so don't let LIBSTDCXX use the default one.

* src/vectors.S: Correctly conditionalise overwriting (or not)
of reset vector.

* src/hal_misc.c (CONSTRUCTORS_END): Fix fencepost error.

* include/arm_stub.h: Remove CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION
and CYG_HAL_GDB_LEAVE_CRITICAL_IO_REGION defines which should remain
as their defaults.
* src/arm.ld: Add SECTION_hal_vsr_table for targets which need the
VSR table in a different location to the rest of the fixed vectors.
* src/vectors.S: Allow hal_platform_setup.h to define
CYGHWR_HAL_ARM_SEPARATE_VSR_TABLE to allow move of hal_vsr_table
to its own section at a different address.

* src/hal_mk_defs.c (main): Export exception vector info
to asm.
* src/arm.ld: Remove previous EABI support and instead use a
different approach incorporating into existing SECTION macros for
better backward compatibility.
* src/hal_misc.c (cyg_hal_invoke_constructors): Rewrite init_array
support for EABI.
There is now nothing copyrightable remaining from Chris Zimman's
earlier work in this package.

* cdl/hal_arm.cdl: Rename EABI option. Set default from
toolchain prefix and flags. Rewrite description.
* include/hal_arch.h: Rename exception vector addresses to
names less likely to potentially clash with applications.
* src/vectors.S: Update vector address names in line with
hal_arch.h change. Rename CYGNUM_HAL_VECTOR_TABLE ->
CYGHWR_HAL_VECTOR_TABLE_BASE.

Some of the following changes were inspired by work from Chris
Zimman. Further changes were also provided, but have not been
included because either they are cosmetic (whitespace changes
etc.) and thus will only make it more difficult to merge in future
updates from public eCos code base in future, increase code size
for those who don't need it, or break compatibility with public
eCos.
* cdl/hal_arm.cdl: Add EABI build option.
* include/hal_arch.h: Add extra CPSR definitions, and exception
vector addresses.
* src/arm.ld: Add EABI support.
* src/hal_misc.c: Add EABI constructor support.
* src/vectors.S: Allow variant/processor/platform to specify
alternate vector table base. Use pretty names from hal_arch.h
for vector offset/addresses.
