Merge llvm-project main llvmorg-12-init-17869-g8e464dd76bef This updates llvm, clang, compiler-rt, libc++, libunwind, lld, lldb and openmp to llvmorg-12-init-17869-g8e464dd76bef, the last commit before the upstream release/12.x branch was created. PR: 255570 (cherry picked from commite8d8bef961) Merge llvm-project 12.0.0 release This updates llvm, clang, compiler-rt, libc++, libunwind, lld, lldb and openmp to llvmorg-12.0.0-0-gd28af7c654d8, a.k.a. 12.0.0 release. PR: 255570 (cherry picked from commitd409305fa3) Disable strict-fp for powerpcspe, as it does not work properly yet Merge commit 5c18d1136665 from llvm git (by Qiu Chaofan) [SPE] Disable strict-fp for SPE by default As discussed in PR50385, strict-fp on PowerPC SPE has not been handled well. This patch disables it by default for SPE. Reviewed By: nemanjai, vit9696, jhibbits Differential Revision: https://reviews.llvm.org/D103235 PR: 255570 (cherry picked from commit715df83abc) Apply upstream libc++ fix to allow building with devel/xxx-xtoolchain-gcc Merge commit 52e9d80d5db2 from llvm git (by Jason Liu): [libc++] add `inline` for __open's definition in ifstream and ofstream Summary: When building with gcc on AIX, it seems that gcc does not like the `always_inline` without the `inline` keyword. So adding the inline keywords in for __open in ifstream and ofstream. That will also make it consistent with __open in basic_filebuf (it seems we added `inline` there before for gcc build as well). Differential Revision: https://reviews.llvm.org/D99422 PR: 255570 (cherry picked from commitd099db2546) Undefine HAVE_(DE)REGISTER_FRAME in llvm's config.h on arm Otherwise, the lli tool (enable by WITH_CLANG_EXTRAS) won't link on arm, stating that __register_frame is undefined. This function is normally provided by libunwind, but explicitly not for the ARM Exception ABI. Reported by: oh PR: 255570 (cherry picked from commitf336b45e94) Merge llvm-project 12.0.1 rc2 This updates llvm, clang, compiler-rt, libc++, libunwind, lld, lldb and openmp to llvmorg-12.0.1-rc2-0-ge7dac564cd0e, a.k.a. 12.0.1 rc2. PR: 255570 (cherry picked from commit23408297fb) Revert libunwind change to fix backtrace segfault on aarch64 Revert commit 22b615a96593 from llvm git (by Daniel Kiss): [libunwind] Support for leaf function unwinding. Unwinding leaf function is useful in cases when the backtrace finds a leaf function for example when it caused a signal. This patch also add the support for the DW_CFA_undefined because it marks the end of the frames. Ryan Prichard provided code for the tests. Reviewed By: #libunwind, mstorsjo Differential Revision: https://reviews.llvm.org/D83573 Reland with limit the test to the x86_64-linux target. Bisection has shown that this particular upstream commit causes programs using backtrace(3) on aarch64 to segfault. This affects the lang/rust port, for instance. Until we can upstream to fix this problem, revert the commit for now. Reported by: mikael PR: 256864 (cherry picked from commit5866c369e4) Merge llvm-project 12.0.1 release This updates llvm, clang, compiler-rt, libc++, libunwind, lld, lldb and openmp to llvmorg-12.0.1-0-gfed41342a82f, a.k.a. 12.0.1 release. PR: 255570 (cherry picked from commit4652422eb4) compilert-rt: build out-of-line LSE atomics helpers for aarch64 Both clang >= 12 and gcc >= 10.1 now default to -moutline-atomics for aarch64. This requires a bunch of helper functions in libcompiler_rt.a, to avoid link errors like "undefined symbol: __aarch64_ldadd8_acq_rel". (Note: of course you can use -mno-outline-atomics as a workaround too, but this would negate the potential performance benefit of the faster LSE instructions.) Bump __FreeBSD_version so ports maintainers can easily detect this. PR: 257392 (cherry picked from commitcc55ee8009)
