Wed Dec 10 16:21:00 GMT 2014
Hi,
Patch bellow adds march/mtune/attribute=knl.
For now this is just silvermont tuning and avx/avx2/avx512 support.
Ok for trunk?
gcc/
* config.gcc: Support "knl".
* config/i386/driver-i386.c (host_detect_local_cpu): Detect "knl".
* config/i386/i386-c.c (ix86_target_macros_internal): Handle
PROCESSOR_KNL.
* config/i386/i386.c (m_KNL): Define.
(processor_target_table): Add "knl".
(PTA_KNL): Define.
(ix86_issue_rate): Add PROCESSOR_KNL.
(ix86_adjust_cost): Ditto.
(ia32_multipass_dfa_lookahead): Ditto.
(get_builtin_code_for_version): Handle "knl".
(fold_builtin_cpu): Ditto.
* config/i386/i386.h (TARGET_KNL): Define.
(processor_type): Add PROCESSOR_KNL.
* config/i386/i386.md (attr "cpu"): Add knl.
* config/i386/x86-tune.def: Add m_KNL.
gcc/testsuite/
* gcc.target/i386/funcspec-5.c: Test avx512f and knl.
