Add support for ARMv8-M Mainline with DSP extension
2016-05-10 Thomas Preud'homme <thomas.preudhomme@arm.com> bfd/ (elf32_arm_merge_eabi_attributes): Add merging logic for Tag_DSP_extension. binutils/ * readelf.c (display_arm_attribute): Add output for Tag_DSP_extension. (arm_attr_public_tags): Define DSP_extension attribute. gas/ * NEWS: Document ARMv8-M and ARMv8-M Security and DSP Extensions. * config/tc-arm.c (arm_ext_dsp): New feature for Thumb DSP instructions. (arm_extensions): Add dsp extension for ARMv8-M Mainline. (aeabi_set_public_attributes): Memorize the feature bits of the architecture selected for Tag_CPU_arch. Use it to set Tag_DSP_extension to 1 for ARMv8-M Mainline with DSP extension. (arm_convert_symbolic_attribute): Define Tag_DSP_extension. * testsuite/gas/arm/arch7em-bad.d: Rename to ... * testsuite/gas/arm/arch7em-bad-1.d: This. * testsuite/gas/arm/arch7em-bad-2.d: New file. * testsuite/gas/arm/arch7em-bad-3.d: Likewise. * testsuite/gas/arm/archv8m-main-dsp-1.d: Likewise. * testsuite/gas/arm/archv8m-main-dsp-2.d: Likewise. * testsuite/gas/arm/archv8m-main-dsp-3.d: Likewise. * testsuite/gas/arm/archv8m-main-dsp-4.d: Likewise. * testsuite/gas/arm/archv8m-main-dsp-5.d: Likewise. * testsuite/gas/arm/attr-march-armv8m.main.dsp.d: Likewise. include/ * elf/arm.h (Tag_DSP_extension): Define. ld/ * testsuite/ld-arm/arm-elf.exp (EABI attribute merging 10 (DSP)): New test. * testsuite/ld-arm/attr-merge-10b-dsp.s: New file. * testsuite/ld-arm/attr-merge-10-dsp.attr: Likewise.
