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

Yaxun Liu	2e8331cab6	[OpenCL] Allow disabling types and declarations associated with extensions ... Added a map to associate types and declarations with extensions. Refactored existing diagnostic for disabled types associated with extensions and extended it to declarations for generic situation. Fixed some bugs for types associated with extensions. Allow users to use pragma to declare types and functions for supported extensions, e.g. #pragma OPENCL EXTENSION the_new_extension_name : begin // declare types and functions associated with the extension here #pragma OPENCL EXTENSION the_new_extension_name : end Differential Revision: https://reviews.llvm.org/D21698 llvm-svn: 289979	2016-12-16 19:22:08 +00:00
