This change includes\nthree commits\n- Libunwind support for the newly introduced DWARF Instruction\n- CodeGen Support for the DWARF Instructions\n- Reversing the changes made in #96377. Due to\n`DW_CFA_AARCH64_negate_ra_state_with_pc`\u0027s requirements to be placed\nimmediately after the signing instruction, this would mean the CFI\nInstruction location was not consistent with the generated location when\nnot using FEAT_PAuthLR. The commit reverses the changes and makes the\nlocation consistent across the different branch protection options.\nWhile this does have a code size effect, this is a negligible one.\n\nFor the ABI information, see here:\nhttps://github.com/ARM-software/abi-aa/blob/853286c7ab66048e4b819682ce17f567b77a0291/aadwarf64/aadwarf64.rst#id23\n\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: 86f76c3b171f95fd0560339f2ad0f4449277cf8d\n" }, { "commit": "f887fe0c04e4821562e35c1488b9ac055e9141b0", "tree": "84833d31957008340a657b0ab65df091da9515b8", "parents": [ "c54b50f826d4fd57768c4772ed1ee065f1e4d784" ], "author": { "name": "Vitaly Buka", "email": "vitalybuka@google.com", "time": "Fri Oct 25 06:12:32 2024" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Fri Oct 25 06:15:37 2024" }, "message": "Revert \"[runtimes] Probe for -nostdlib++ and -nostdinc++ with the C compiler\" (#113653)\n\nReverts llvm/llvm-project#108357\n\nBreaks https://lab.llvm.org/buildbot/#/builders/164/builds/3908 and\nsimilar bots\n\nNOKEYCHECK\u003dTrue\nGitOrigin-RevId: 240e4780680f0d6a760be1b9ea432f410424b3a5\n" }, { "commit": "c54b50f826d4fd57768c4772ed1ee065f1e4d784", "tree": "5d0cc85a731c7a92b4e3cede030b23a584ae72c9", "parents": [ "59d05179e3b1ba5534f9829b7d47b36ccc3da357" ], "author": { "name": "Martin Storsjö", "email": "martin@martin.st", "time": "Thu Oct 24 20:46:04 2024" }, "committer": { "name": "Copybara-Service", "email": "copybara-worker@google.com", "time": "Thu Oct 24 20:50:56 2024" }, "message": "[runtimes] Probe for -nostdlib++ and -nostdinc++ with the C compiler (#108357)\n\nWhile these flags semantically are relevant only for C++, we do add them\nto CMAKE_REQUIRED_FLAGS if they are detected.
