Subject: [PATCH 5/8] Optimizations for IBM z13
|
||
|
|
|
||
|
|
Perform some optimizations for IBM z13:
|
||
|
|
- Compile with -O2 instead of -O.
|
||
|
|
- Streamline vector loads/stores.
|
||
|
|
- Define the vvrsum2 macro.
|
||
|
|
|
||
|
|
Also, use the compile option -march=z13 instead of -march=native.
