Subject: [PATCH] Use jobserver on LTO from make
|
|
|
|
This should avoid executing PARALELISM threads for each linker call but
|
|
rather limits it to the basic jobs given to make.
|
|
|
|
Previous behaviour could be 8 make threads, each spawning 8 LTO threads,
|
|
while here it should append its jobs to make and leave it to the make
|
|
itself to distribute.
