Bug ID: 84402
Summary: [meta] GCC build system: parallelism bottleneck
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap
Assignee: unassigned at gcc dot gnu.org
Reporter: marxin at gcc dot gnu.org
Target Milestone: ---
As discussed yesterday on IRC, current build of GCC has various issues that
make it not fully parallelable on machines with higher number of CPUs.
I've did a hack to make where I recorded timestamp when a target is triggered
and finished:
https://github.com/marxin/make/tree/timestamp
Then I built GCC with -j1 and used following parser to generate reports:
https://github.com/marxin/script-misc/blob/master/parse-make-log.py
I prepared various reports that I'm going to add as attachments.
