Subject: [PATCH 42/47] Reuse -fdebug-prefix-map to replace -ffile-prefix-map
|
||
|
|
|
||
|
|
The oe-core may use external toolchain to compile,
|
||
|
|
which may not support -ffile-prefix-map.
|
||
|
|
|
||
|
|
Since we use -fdebug-prefix-map to do the same thing,
|
||
|
|
so we could reuse it to replace -ffile-prefix-map.
|
||
|
|
|
||
|
|
Upstream-Status: Inappropriate[oe-core specific]
