Subject: [Bug c++/50947] New: ICE on armhf with llvm-2.x
Date: Tue, 01 Nov 2011 20:12:00 -0000 [thread overview]
Message-ID: <bug-50947-4@http.gcc.gnu.org/bugzilla/> (raw)
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=50947
Bug #: 50947
Summary: ICE on armhf with llvm-2.x
Classification: Unclassified
Product: gcc
Version: 4.6.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: konstantinos.margaritis@linaro.org
Created attachment 25678
--> http://gcc.gnu.org/bugzilla/attachment.cgi?id=25678
minimal testcase produced using delta tool from
lib/ExecutionEngine/Interpreter/ExternalFunctions.cpp in llvm-2.x
llvm-2.x fail to build from source on Debian armhf, all due to a g++ ICE:
http://buildd.debian-ports.org/status/fetch.php?pkg=llvm-2.7&arch=armhf&ver=2.7-6.2&stamp=1311446819
http://buildd.debian-ports.org/status/fetch.php?pkg=llvm-2.8&arch=armhf&ver=2.8-7&stamp=1309205992
http://buildd.debian-ports.org/status/fetch.php?pkg=llvm-2.9&arch=armhf&ver=2.9%2Bdfsg-3&stamp=1309210849
Originally the bug appeared with g++-4.6.1-10 but it still fails with
g++-4.6.2-3 (latest Debian/unstable).

Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.6/README.Bugs> for instructions.
I used the delta package to produce a minimal testcase for the ICE
which I attach.
You can reproduce the ICE with:
g++ -O2 -fpermissive -w llvm_ExternalFunctions-min.i
The bug has also been filed on the Debian BTS:
