Bug ID: 68331
Summary: [meta-bug] fipa-pta issues
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ipa
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
From https://gcc.gnu.org/ml/gcc-patches/2015-11/msg01630.html :
1)
we lack good testing coverage for IPA PTA so wrong-code bugs might still exist
2)
IPA PTA can use a _lot_ of memory and compile-time
3)
for existing wrong-code issues I have merely dumbed down the use of the
analysis result resulting in weaker alias analysis compared to the local PTA
(for some cases)
Because of 2 and no good way to avoid this I decided to not make
fixing 3 a priority (and 1 still holds).
