However, this prevents some optimizationsfrom adequately analyzing them because of the nature of weak linkage.This patch replaces the weak linkage with weak_odr linkage so we canstatically assert that multiple declarations of the same kernel willhave the same definition.Reviewed By: jdoerfertDifferential Revision: https://reviews.llvm.org/D122443 List of files: /llvm-project-15.0.7/clang/test/OpenMP/assumes_include_nvptx.cpp Thu, 24 Mar 2022 23:32:05 +0000 Joseph Huber <jhuber6@vols.utk.edu> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/OpenMP/assumes_include_nvptx.cpp#1b1c8d83 [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 List of files: /llvm-project-15.0.7/clang/test/OpenMP/assumes_include_nvptx.cpp Sun, 16 Jan 2022 09:53:11 +0000 hyeongyu kim <gusrb406@snu.ac.kr> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/OpenMP/assumes_include_nvptx.cpp#4b5c3e59 [OpenMP] Remove doing assumption propagation in the front end.This patch removes the assumption propagation that was added in D110655primarily to get assumption informatino on opaque call sites foroptimizations.

Currently this applies the caller's assumption attributes toany calls contained within it. So, if a call occurs inside an OpenMPassumes region to a function outside that region, we will assume thatcall respects the assumptions. This is primarily useful for inlineassembly calls used heavily in the OpenMP GPU device runtime, whichallows us to then make judgements about what the ASM will do.Reviewed By: jdoerfertDifferential Revision: https://reviews.llvm.org/D110655 List of files: /llvm-project-15.0.7/clang/test/OpenMP/assumes_include_nvptx.cpp Tue, 28 Sep 2021 19:53:55 +0000 Joseph Huber <jhuber6@vols.utk.edu> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/OpenMP/assumes_include_nvptx.cpp#45e8e084 [OpenMP] Encode `omp [...] assume[...]` assumptions with `omp[x]` prefixSince these assumptions are coming from OpenMP it makes sense to markthem as such in the generic IR encoding.

The GPU cannot share data between its threads so must allocate global orshared memory to store the data in. Currently this is implemented fully in the frontend using the`__kmpc_data_sharing_push_stack` and __kmpc_data_sharing_pop_stack` functions to emulate standardCPU stack sharing. The front-end scans the target region for variables that escape the region andmust be shared between the threads. Each variable then has a field created for it in a global recordtype.This patch replaces this functinality with a single allocation command, effectively mimicing analloca instruction for the variables that must be shared between the threads. This will be muchslower than the current solution, but makes it much easier to optimize as we can analyze eachvariable independently and determine if it is not captured. In the future, we can replace thesecalls with an `alloca` and small allocations can be pushed to shared memory.Reviewed By: tianshilei1992Differential Revision: https://reviews.llvm.org/D97680 List of files: /llvm-project-15.0.7/clang/test/OpenMP/assumes_include_nvptx.cpp Mon, 22 Mar 2021 20:34:11 +0000 Joseph Huber <jhuber6@vols.utk.edu> http://172.16.0.5:8080/history/llvm-project-15.0.7/clang/test/OpenMP/assumes_include_nvptx.cpp#2e6e4e6a [OpenMP] Add initial support for `omp [begin/end] assumes`The `assumes` directive is an OpenMP 5.1 feature that allows the user toprovide assumptions to the optimizer.
