* Update more file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | | to reflect the new license. These used slightly different spellings that defeated my regular expressions. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351648
* [OpenMP] Implement OpenMP 5.0 affinity format functionalityJonathan Peyton2018-12-131-5/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds the affinity format functionality introduced in OpenMP 5.0. This patch adds: Two new environment variables: OMP_DISPLAY_AFFINITY=TRUE|FALSE OMP_AFFINITY_FORMAT=<string> and Four new API: 1) omp_set_affinity_format() 2) omp_get_affinity_format() 3) omp_display_affinity() 4) omp_capture_affinity() The affinity format functionality has two ICV's associated with it: affinity-display-var (bool) and affinity-format-var (string). The affinity-display-var enables/disables the functionality through the envirable OMP_DISPLAY_AFFINITY. The affinity-format-var is a formatted string with the special field types beginning with a '%' character similar to printf For example, the affinity-format-var could be: "OMP: host:%H pid:%P OStid:%i num_threads:%N thread_num:%n affinity:{%A}" The affinity-format-var is displayed by every thread implicitly at the beginning of a parallel region when any thread's affinity has changed (including a brand new thread being spawned), or explicitly using the omp_display_affinity() API. The omp_capture_affinity() function can capture the affinity-format-var in a char buffer. And omp_set|get_affinity_format() allow the user to set|get the affinity-format-var explicitly at runtime. omp_capture_affinity() and omp_get_affinity_format() both return the number of characters needed to hold the entire string it tried to make (not including NULL character). If not enough buffer space is available, both these functions truncate their output. Differential Revision: https://reviews.llvm.org/D55148 llvm-svn: 349089
* [OpenMP][OMPT] A few improvementsJonathan Peyton2018-09-261-2/+4
| | | | | | | | | | | | | | This change includes miscellaneous improvements as follows: 1) Added ompt_get_proc_id() implementation for Windows 2) Added parser and print tool for omp-tool-var, just in case it needs to be printed (OMP_DISPLAY_ENV) 3) omp_control_tool is exported on Windows Patch by Hansang Bae Differential Revision: https://reviews.llvm.org/D50538 llvm-svn: 343137
* Remove const from variables with dynamic memoryJonas Hahnfeld2017-11-091-6/+6
| | | | | | | | | | | | | | | | | | | Allocated memory is typically not 'const' if it needs to be freed. This patch removes around 50 wrong const attributes, modifies the corresponding functions and finally gets rid of some const_casts. These have especially been strange for __kmp_str_fname_free() that added a 'const' to call __kmp_str_free() which removed it again. Two minor cleanups that I performed in this process: * __kmp_tool_libraries now lives in kmp_settings.cpp as it is used nowhere else. * __kmp_msg_empty was removed as it was never used and Clang now complained that it was assigned a string literal that is 'const char *'.

* Apply formatting changesJonathan Peyton2017-10-201-2/+0
| | | | | | | | | | .clang-format's comments are removed and a (hopefully) final set of formatting changes are applied. Differential Revision: https://reviews.llvm.org/D38837 Differential Revision: https://reviews.llvm.org/D38920 llvm-svn: 316227
* Remove unnecessary semicolonsJonathan Peyton2017-09-271-57/+55
| | | | | | | | Removes semicolons after if {} blocks, function definitions, etc. I was able to apply the large OMPT patch cleanly on top of this one with no conflicts. llvm-svn: 314340
* Use va_copy instead of __va_copy to fix building libomp against musl libcJonathan Peyton2017-08-191-1/+1

* OpenMP RTL cleanup: eliminated warnings with -Wcast-qual.Andrey Churbanov2017-07-031-5/+5
| | | | | | | | | | | Changes are: replaced C-style casts with cons_cast and reinterpret_cast; type of several counters changed to signed; type of parameters of 32-bit and 64-bit AND and OR intrinsics changes to unsigned; changed files formatted using clang-format version 3.8.1.

* Clang-format and whitespace cleanup of source codeJonathan Peyton2017-05-121-767/+622
| | | | | | | | | | | | | This patch contains the clang-format and cleanup of the entire code base. Some of clang-formats changes made the code look worse in places. A best effort was made to resolve the bulk of these problems, but many remain. Most of the problems were mangling line-breaks and tabbing of comments.
