Bug ID: 63422
Summary: [5.0 Regression] ICE in freqs_to_counts_path, at
tree-ssa-threadupdate.c:981
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: middle-end
Assignee: unassigned at gcc dot gnu.org
Reporter: Joost.VandeVondele at mat dot ethz.ch
In the one day between r215702 and 215747 trunk started failing to compile CP2K
with '-c -flto=jobserver -fprofile-use '. Several lto instances fail with:
/data/vjoost/gnu/cp2k/cp2k/makefiles/../src/core_ae.F:58:0: internal compiler
error: in freqs_to_counts_path, at tree-ssa-threadupdate.c:988

given the combination of lto and profile-use it will be difficult to generate a
testcase (other than building full cp2k with profile feedback, which is
somewhat involved).

I suspect this is caused by r215739

Yes, this function is new in r215739. I will see if I can trigger it
tomorrow. If you have a smaller test case that would be great. Or even
if you can give me the gcda file and preprocessed source that will
help.

this only happens with LTO, so I'm not sure there is easily a source file I can
provide (with ~1000 .gdca files).
I tried some smaller programs, but didn't see the problem yet.

Thanks for the test case. Reproduced and looking at it.
