Subject: [PATCH 029/188] LoongArch: Increase cost of vector aligned
|
||
|
|
store/load.
|
||
|
|
|
||
|
|
Based on SPEC2017 performance evaluation results, it's better to make them equal
|
||
|
|
to the cost of unaligned store/load so as to avoid odd alignment peeling.
|
||
|
|
|
||
|
|
gcc/ChangeLog:
|
||
|
|
|
||
|
|
* config/loongarch/loongarch.cc
|
||
|
|
(loongarch_builtin_vectorization_cost): Adjust.
