Summary: IPA reference tends to explode in memory use with
-fprofile-generate
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: tree-optimization
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: hubicka@gcc.gnu.org
Compiling Mozilla, IPA reference OOMs for me after allocating about 9GB of
bitmaps. It is because the counters inserted to every function by
profile-generate are especially bad for the datastructure used by
IPA-reference.
As a temporary workaround, I will probably disable IPA reference with profiling
is active.
