Bug #: 55194
Summary: h8300 ICE during conftest in libgcc dwarf2out:7605
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: j...@gcc.gnu.org
When building newlib using the gcc-svn head, the compiler generates assembly
language that cannot be assembled by the binutils cvs head or 2.22
xgcc (GCC) 4.8.0 20121103 (experimental) [trunk revision 193124]
This is enough to trip the bug:
/home/joel/v850/tools/b-gcc-svn/./gcc/xgcc
-B/home/joel/v850/tools/b-gcc-svn/./gcc/ -c -O2 -g h8300_bug.c
Dropping the -g is sufficient to let it compile.
Test case is very basic:
int main(int argc, char **argv)
{
return 0;
}
The full command line:
configure:3374: /home/joel/v850/tools/b-gcc-svn/./gcc/xgcc
-B/home/joel/v850/tools/b-gcc-svn/./gcc/ -nostdinc
