[ARM] Add linker support for ARMv8-R === Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to add support for ARMv8-R in the linker. === Patch description === This patch is composed of 3 changes: 1) The main change is the addition of the logic for merging a file whose Tag_CPU_arch build attribute is 15 (ARMv8-R). Namely, all pre-ARMv8 are merged into ARMv8-R as well as ARMv8-R itself. ARMv8-A (14) merges into ARMv8-A. ARMv8-M Baseline (16) and Mainline (17) are not allowed to merge merge with ARMv8-R. Note that merging only occurs if the two profiles are identical or one is S (Application or Realtime) and the other is R. 2) using_thumb_only, using_thumb2_bl, using_thumb2 and arch_has_arm_nop are updated according to capabilities of ARMv8-R and their BFD_ASSERT updated to reflect that the logic is valid for ARMv8-R. 3) 2 build attribute merging tests are added to test the first change. 2017-06-24 Thomas Preud'homme <thomas.preudhomme@arm.com> bfd/ * elf32-arm.c (using_thumb_only): Update list of architectures in BFD_ASSERT for which the logic is valid. (using_thumb2_bl): Likewise. (using_thumb2): Likewise and return true for ARMv8-R. (arch_has_arm_nop): Likewise. (tag_cpu_arch_combine): New v8r table for ARMv8-R Tag_CPU_arch merging logic. Update commentis for value 15 of v8m_baseline, v8m_mainline and v4t_plus_v6_m arrays. Use v8r array to decide merging of value 15 of Tag_CPU_arch. ld/ * testsuite/ld-arm/arm-elf.exp (EABI attribute merging 11): New test. (EABI attribute merging 12): Likewise. * testsuite/ld-arm/attr-merge-11a.s: New file. * testsuite/ld-arm/attr-merge-11b.s: New file. * testsuite/ld-arm/attr-merge-11.attr: New file. * testsuite/ld-arm/attr-merge-12a.s: New file. * testsuite/ld-arm/attr-merge-12b.s: New file. * testsuite/ld-arm/attr-merge-12.attr: New file. 2017-06-24 17:48:08 +08:00			`.arch armv8-r`
