Bug #: 51263
Summary: ICE in inline_small_functions when compiling scummvm
with -O2 -flto
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: middle-end
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: m...@use.net
With current trunk, compiling scummvm 1.4.0
(http://prdownloads.sourceforge.net/scummvm/scummvm-1.4.0.tar.bz2?download):
$ CXXFLAGS="-O2 -flto" CFLAGS="-O2 -flto" ./configure --enable-all-engines
Running ScummVM configure...

$ make
[...]
engines/parallaction/balloons.cpp:756:1: internal compiler error: in
inline_small_functions, at ipa-inline.c:1421
with -j7, this one happens first, but is likely the same root issue:
In file included from video/smk_decoder.cpp:37:0:
./audio/audiostream.h:303:7: internal compiler error: in
inline_small_functions, at ipa-inline.c:1421
I tried reproducing with just -O1 -finline-small-functions, but that didn't
trip the issue.
Pre-processed source file attached, reproduce by:
bunzip2 balloons.i.bz2
g++ -O2 balloons.i
