Subject: [gcc/devel/omp/gcc-12] amdgcn: Add preprocessor builtins for every processor type
Date: Tue, 6 Dec 2022 13:57:43 +0000 (GMT) [thread overview]
Message-ID: <20221206135743.56E00384C90B@sourceware.org> (raw)
https://gcc.gnu.org/g:a8db05dcf5819c7ddd5c71da40bb08a533551ae9
commit a8db05dcf5819c7ddd5c71da40bb08a533551ae9
Author: Paul-Antoine Arras <pa@codesourcery.com>
Date: Thu Dec 1 15:09:54 2022 +0100
amdgcn: Add preprocessor builtins for every processor type
Provide a specific builtin for each possible value of '-march'.
gcc/ChangeLog:
* config/gcn/gcn-opts.h (TARGET_FIJI): -march=fiji.
(TARGET_VEGA10): -march=gfx900.
(TARGET_VEGA20): -march=gfx906.
(TARGET_GFX908): -march=gfx908.
(TARGET_GFX90a): -march=gfx90a.
* config/gcn/gcn.h (TARGET_CPU_CPP_BUILTINS): Define a builtin that
uniquely maps to '-march'.
(cherry picked from commit e41b243302e9964e642924329826448afb21d28e)
