[compiler-rt] Add CMake option to enable execute-only code generation on AArch64 (#140555) For a full toolchain supporting execute-only code generation the runtime libraries also need to be pre-compiled with it enabled. The generic RUNTIMES_EXECUTE_ONLY_CODE CMake option can now be used during build configuration to enable execute-only code generation in compiler-rt. The build option can only be enabled for a runtimes build of compiler-rt, because a recent version of Clang is needed to correctly compile assembly files with execute-only code support.

[msan] Reland with even more improvement: Improve packed multiply-add instrumentation (#153353) This reverts commit cf002847a464c004a57ca4777251b1aafc33d958 i.e., relands ba603b5e4d44f1a25207a2a00196471d2ba93424. It was reverted because it was subtly wrong: multiplying an uninitialized zero should not result in an initialized zero. This reland fixes the issue by using instrumentation analogous to visitAnd (bitwise AND of an initialized zero and an uninitialized value results in an initialized value). Additionally, this reland expands a test case; fixes the commit message; and optimizes the change to avoid the need for horizontalReduce. The current instrumentation has false positives: it does not take into account that multiplying an initialized zero value with an uninitialized value results in an initialized zero value This change fixes the issue during the multiplication step. The horizontal add step is modeled using bitwise OR. Future work can apply this improved handler to the AVX512 equivalent intrinsics (x86_avx512_pmaddw_d_512, x86_avx512_pmaddubs_w_512.) and AVX VNNI intrinsics. | 11 个月前 | |
Update the file headers across all of the LLVM projects in the monorepo to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636 | 7 年前 | |
