x86-64: Add Intel LAM property support Add Intel Linear Address Masking (LAM) property support. LAM modifies the checking that is applied to 64-bit linear addresses, allowing software to use of the untranslated address bits for metadata. bfd/ * elf-linker-x86.h (elf_x86_cet_report): Renamed to ... (elf_x86_prop_report): This. (elf_linker_x86_params): Add lam_u48, lam_u57, lam_u48_report and lam_u57_report. * elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): Support GNU_PROPERTY_X86_FEATURE_1_LAM_U48 and GNU_PROPERTY_X86_FEATURE_1_LAM_U57. (_bfd_x86_elf_link_fixup_gnu_properties): Keep LAM features only for 64-bit output. binutils/ * NEWS: Mention LAM_U48 and LAM_U57 support. * elfedit.c (elf_x86_feature): Support lam_u48 and lam_u57. (usage): Add lam_u48 and lam_u57. * readelf.c (decode_x86_feature_1): Support LAM_U48 and LAM_U57. * doc/binutils.texi: Update elfedit with lam_u48 and lam_u57 support. * testsuite/binutils-all/x86-64/lam-u48.d: New file. * testsuite/binutils-all/x86-64/lam-u48.s: Likewise. * testsuite/binutils-all/x86-64/lam-u57.d: Likewise. * testsuite/binutils-all/x86-64/lam-u57.s: Likewise. include/ * elf/common.h (GNU_PROPERTY_X86_FEATURE_1_LAM_U48): New.
