* 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.
