Bug ID: 99785
Summary: Awful lot of time spent building gl.cc in Firefox
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mh+gcc at glandium dot org
Target Milestone: ---

gl.ii.gz
Compiling the attached preprocessed source takes 27 minutes with GCC 10 with
`g++ -o gl.o -c gl.ii -O2 -std=gnu++17 -g -pipe` and a grand total of 21GB of
memory spread between cc1plus (15G) and gas (6GB). It's also slow to process at
-O0.
This goes up to 4 hours (!) with GCC 11 and less than 1 minute with clang.
