[Clang/Test]: Rename enable_noundef_analysis to disable-noundef-analysis and turn it off by defaultTurning 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: D108453Reviewed By: eugenisDifferential 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.Reviewed By: eugenisDifferential Revision: https://reviews.llvm.org/D108453Resolve lit failures in clang after 8ca4b3e's landFix lit test failures in clang-ppc* and clang-x64-windows-msvcFix missing failures in clang-ppc64be* and retry fixing clang-x64-windows-msvcFix internal_clone(aarch64) inline assembly List of files: /llvm-project-15.0.7/clang/test/OpenMP/declare_variant_mixed_codegen.c

fd739804 - [test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differences

Thu, 31 Dec 2020 08:27:11 +0000

[test] Add {{.*}} to make ELF tests immune to dso_local/dso_preemptable/(none) differencesFor 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 similarto -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 `{{.*}} `.

befb4be3 - [OpenMP] `omp begin/end declare variant` - part 2, sema ("+CG")

Tue, 25 Feb 2020 22:04:06 +0000

[OpenMP] `omp begin/end declare variant` - part 2, sema ("+CG")This is the second part loosely extracted from D71179 and cleaned up.This patch provides semantic analysis support for `omp begin/end declarevariant`, mostly as defined in OpenMP technical report 8 (TR8) [0].The sema handling makes code generation obsolete as we generate "theright" calls that can just be handled as usual. This handling alsoapplies to the existing, albeit problematic, `omp declare variantsupport`. As a consequence a lot of unneeded code generation andcomplexity is removed.A major purpose of this patch is to provide proper `math.h`/`cmath`support for OpenMP target offloading. See PR42061, PR42798, PR42799. Thecurrent code was developed with this feature in mind, see [1].The logic is as follows:If we have seen a `#pragma omp begin declare variant match()`but not the corresponding `end declare variant`, and we find a functiondefinition we will: 1) Create a function declaration for the definition we were about to generate. 2) Create a function definition but with a mangled name (according to ``). 3) Annotate the declaration with the `OMPDeclareVariantAttr`, the same one used already for `omp declare variant`, using and the mangled function definition as specialization for the context defined by ``.When a call is created we inspect it. If the target has an`OMPDeclareVariantAttr` attribute we try to specialize the call. To thisend, all variants are checked, the best applicable one is picked and anew call to the specialization is created. The new call is used insteadof the original one to the base function. To keep the AST printing andtooling possible we utilize the PseudoObjectExpr. The original call isthe syntactic expression, the specialized call is the semanticexpression.[0] https://www.openmp.org/wp-content/uploads/openmp-TR8.pdf[1] https://reviews.llvm.org/D61399#change-496lQkg0mhRNReviewers: kiranchandramohan, ABataev, RaviNarayanaswamy, gtbercea, grokos, sdmitriev, JonChesterfield, hfinkel, fghanim, aaron.ballmanSubscribers: bollu, guansong, openmp-commits, cfe-commitsTags: #clangDifferential Revision: https://reviews.llvm.org/D75779 List of files: /llvm-project-15.0.7/clang/test/OpenMP/declare_variant_mixed_codegen.c

Sun, 02 Feb 2020 20:23:47 +0000

[CodeGenModule] Assume dso_local for -fpic -fno-semantic-interpositionSummary:Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaultsto -fsemantic-interposition).Users need to specify -fsemantic-interposition to get semanticinterposition behavior.Semantic interposition is currently a best-effort feature. There maystill be some cases where it is not handled well.Reviewers: peter.smith, rnk, serge-sans-paille, sfertile, jfb, jdoerfertSubscribers: dschuff, jyknight, dylanmckay, nemanjai, jvesely, kbarton, fedor.sergeev, asb, rbar, johnrusso, simoncook, sabuasal, niosHD, jrtc27, zzheng, edward-jones, atanasyan, rogfer01, MartinMosbeck, brucehoult, the_o, arphaman, PkmX, jocewei, jsji, Jim, lenary, s.egerton, pzheng, sameer.abuasal, apazos, luismarques, cfe-commitsTags: #clangDifferential Revision: https://reviews.llvm.org/D73865 List of files: /llvm-project-15.0.7/clang/test/OpenMP/declare_variant_mixed_codegen.c
