56069b5c - [OpenMP] Support `std::complex` math functions in target regions

Thu, 06 Aug 2020 20:46:44 +0000

[OpenMP] Support `std::complex` math functions in target regionsThe last (big) missing piece to get "math" working in OpenMP targetregions (that I know of) was complex math functions, e.g.,`std::sin(std::complex)`. With this patch we overload the systemtemplate functions for these operations with versions that have beendistilled from `libcxx/include/complex`. We use the same `omp begin/end declare variant`mechanism we use for other math functions before, except that we thistime overload templates (via D85735).Reviewed By: JonChesterfieldDifferential Revision: https://reviews.llvm.org/D85777 List of files: /llvm-project-15.0.7/clang/test/Headers/nvptx_device_math_complex.cpp

b5667d00 - [OpenMP][CUDA] Fix std::complex in GPU regions

Fri, 10 Jul 2020 21:45:02 +0000

[OpenMP][CUDA] Fix std::complex in GPU regionsThe old way worked to some degree for C++-mode but in C mode we actuallytried to introduce variants of macros (e.g., isinf). To make both modeswork reliably we get rid of those extra variants and directly use NVIDIAintrinsics in the complex implementation. While this has to be revisitedas we add other GPU targets which want to reuse the code, it should befine for now.Reviewed By: tra, JonChesterfield, yaxunlDifferential Revision: https://reviews.llvm.org/D83591 List of files: /llvm-project-15.0.7/clang/test/Headers/nvptx_device_math_complex.cpp

e3e47e80 - [OpenMP] Make complex soft-float functions on the GPU weak definitions

Thu, 09 Jul 2020 06:04:16 +0000

[OpenMP] Make complex soft-float functions on the GPU weak definitionsTo avoid linkage errors we have to ensure the linkage allows multipledefinitions of these compiler inserted functions. Since they are on thecold path of complex computations, we want to avoid `inline`. Instead,we opt for `weak` and `noinline` for now.

d999cbc9 - [OpenMP] Initial support for std::complex in target regions

Sun, 12 Apr 2020 07:10:28 +0000

[OpenMP] Initial support for std::complex in target regionsThis simply follows the scheme we have for other wrappers. It resolvesthe current link problem, e.g., `__muldc3 not found`, when std::complexoperations are used on a device.This will not allow complex make math function calls to work properly,e.g., sin, but that is more complex (pan intended) anyway.Reviewed By: tra, JonChesterfieldDifferential Revision: https://reviews.llvm.org/D80897 List of files: /llvm-project-15.0.7/clang/test/Headers/nvptx_device_math_complex.cpp
