hyeongyukim	aacfbb953e	[Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by default Turning on `enable_noundef_analysis` flag allows better codegen by removing freeze instructions. I modified clang by renaming `enable_noundef_analysis` flag to `disable-noundef-analysis` and turning it off by default. Test updates are made as a separate patch: D108453 Reviewed By: eugenis Differential Revision: https://reviews.llvm.org/D105169 [Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by default (2) This patch updates test files after D105169. Autogenerated test codes are changed by `utils/update_cc_test_checks.py,` and non-autogenerated test codes are changed as follows: (1) I wrote a python script that (partially) updates the tests using regex: {F18594904} The script is not perfect, but I believe it gives hints about which patterns are updated to have `noundef` attached. (2) The remaining tests are updated manually.

hyeongyu kim	98e96663f6	[InstCombine] Update InstCombine to use poison instead of undef for shufflevector's placeholder (3/3) This patch is for fixing potential shufflevector-related bugs like D93818. As D93818, this patch change shufflevector's default placeholder to poison. To reduce risk, it was divided into several patches, and this patch is for InstCombineVectorOps.

Fangrui Song	fd739804e0	[test] Add {{.}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences For a default visibility external linkage definition, dso_local is set for ELF -fno-pic/-fpie and COFF and Mach-O. Since default clang -cc1 for ELF is similar to -fpic ("PIC Level" is not set), this nuance causes unneeded binary format differences. To make emitted IR similar, ELF -cc1 -fpic will default to -fno-semantic-interposition, which sets dso_local for default visibility external linkage definitions. To make this flip smooth and enable future (dso_local as definition default), this patch replaces (function) `define ` with `define{{.}} `, (variable/constant/alias) `= ` with `={{.}} `, or inserts appropriate `{{.}} `.	2020-12-31 00:27:11 -08:00
Fangrui Song	dbc96b518b	Revert "[CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition" This reverts commit `789a46f2d7`. Accidentally committed.	2020-02-03 10:09:39 -08:00
Fangrui Song	789a46f2d7	[CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition Summary: Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaults to -fsemantic-interposition). Users need to specify -fsemantic-interposition to get semantic interposition behavior. Semantic interposition is currently a best-effort feature. There may still be some cases where it is not handled well.
