* [DependenceAnalysis] Dependecies for loads marked with "ivnariant.load" ↵Evgeniy Brevnov2019-11-191-6/+19
| | | | | | | | | | | | | | | | | | | should not be shared with general accesses. Fix for https://bugs.llvm.org/show_bug.cgi?id=42151 Summary: Dependence anlysis has a mechanism to cache results. Thus for particular memory access the cache keep track of side effects in basic blocks. The problem is that for invariant loads dependepce analysis legally ignores many dependencies due to a special semantic rules for such loads. But later results calculated for invariant load retrived from the cache for general case acceses. As a result we have wrong dependence information causing GVN to do illegal transformation. Fixes, T42151. Proposed solution is to disable caching of invariant loads. I think such loads a pretty rare and it doesn't make sense to extend caching mechanism for them.

* [libunwind] Adjust the signal_frame test for ArmMikhail Maltsev2019-11-191-1/+7
| | | | | | | | | | | | | | | | | | | | Summary: This patch adjusts the signal_frame.pass.cpp to pass on Arm targets: * When Arm EHABI is used the unwinder does not use DWARF, hence the DWARF-specific check unw_is_signal_frame() must be disabled. * Certain C libraries don't include EH tables, so the unwinder must not try to step out of main(). The patch moves the test code out of main() into a separate function to avoid this.

* [clang][IFS] Driver pipeline: generate interface stubs after standard pipeline.Puyan Lotfi2019-11-196-37/+123
| | | | | | | | | | | | | | | | | Up until now, clang interface stubs has replaced the standard PP -> C -> BE -> ASM -> LNK pipeline. With this change, it will happen in conjunction with it. So what when you build your code you will get an a.out or lib.so as well as an interface stub file. Example: clang -shared -o libfoo.so -emit-interface-stubs ... will generate both a libfoo.so and a libfoo.ifso. The .so file will contain the code from the standard compilation pipeline and the .ifso file will contain the ELF stub library. Differential Revision: https://reviews.llvm.org/D70274

* [OpenMP] Remove -Wl,-fini=__kmp_internal_end_finiAaron Puchert2019-11-194-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The termination function duplicated the functionality of the __attribute((destructor))-annotated function __kmp_internal_end_fini, and we have no indication that this doesn't work. The function might cause issues with link-time optimization turned on: until very recently, none of the usual linkers was reporting functions named in -Wl,-fini as used to the LTO plugin, so it might be dropped. If the function is dropped, -Wl,-fini=__kmp_internal_end_fini doesn't do what we want: with ld.bfd and lld it drops the FINI attribute from .dynamic and with gold we get FINI = 0x0, which leads to a crash on cleanup. This can be reproduced by building with -DLLVM_ENABLE_PROJECTS="clang;openmp" \ -DLLVM_ENABLE_LTO=Thin \ -DLLVM_USE_LINKER=gold The issue in lld has been fixed in f95273f75aa, but gold remains without fix so far.
