Bug ID: 69750
Summary: ICE in sh64 targetted gcc-6
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: dhowells at redhat dot com
Target Milestone: ---
When cross-building gcc-6 for sh64, the builds fail when configuring libgcc
with an ICE. This can be replicated by running the following command in the
build directory:
echo 'int main() { return 0; }' | ./gcc/xgcc -x c -c -g - -B ./gcc
-fexceptions
The gcc being built is the following:
%global DATE 20160205
%global SVNREV 233185
%global gcc_version 6.0.0
gcc is configured as follows:
CC=gcc \
CXX=g++ \
CFLAGS='-O2 -g -Wall -Wformat-security -fexceptions -fstack-protector-strong
--param=ssp-buffer-size=4 -grecord-gcc-switches -mtune=generic' \
