Subject: [PATCH] std.build: fix handling of -Dcpu
|
||
|
|
|
||
|
|
Currently -Dcpu is completely ignored if -Dtarget isn't passed as well.
|
||
|
|
Further, -Dcpu=baseline is ignored even if -Dtarget=native is passed.
|
||
|
|
|
||
|
|
This patch fixes these 2 issues, always respecting the -Dcpu option if
|
||
|
|
present.
