Bug ID: 98746
Summary: [11 Regression] memory hog for a lto+pgo build on
powerpc64*-linux-gnu
Product: gcc
Version: 11.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: doko at debian dot org
Target Milestone: ---
seen with the trunk. A native combined profiled & lto build takes a bit more
than 16GB of memory with -j16, and just under 8GB with -j4 and link
serialization set to 1. I don't see this on other 64bit builds.
marking as a regression, a make -j4 build with 8GB of memory does succeed with
GCC 10.
attaching memory usage reports for ppc64el -j16 and -j4, plus a comparison for
x86_64.
