Bug #: 52471
Summary: ICE bootstrapping GCC 4.7.0-20120302 on x86_64 OpenBSD
Classification: Unclassified
Product: gcc
Version: 4.7.0
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: bootstrap
AssignedTo: unassigned@gcc.gnu.org

libgcc2.i
While bootstrapping GCC 4.7.0-20120302 on x86_64 OpenBSD (an unsupported
platform; see #39572) I get an internal compiler error.
Configured with:
../gcc/configure --program-suffix=-4.7.0-rc1 --enable-threads
In directory /storage/gcc470rc1/obj/x86_64-unknown-openbsd4.8/libgcc

This ICE occurs whether I'm using the bootstrapping compiler (gcc 4.7.0), the
previous gcc I built (gcc 4.6.2), or the system compiler (gcc 4.2.1).
Attached find the libgcc2.i produced from
/storage/gcc470rc1/obj/./gcc/xgcc -v -save-temps
I did NOT encounter this problem while bootstrapping gcc 4.6.2.
APPENDIX
--------
Here are my source edits to enable bootstrapping on x86_64 OpenBSD. I haven't
been able to obtain a release from my employer to submit these myself, but
hopefully they are trivial enough that it is appropriate for someone else to do
the copy and paste:
libgcc/config.host - add x86_64, same as i[34567]86.
i[34567]86-*-openbsd*)
;;
+x86_64-*-openbsd*)
+ ;;
gcc/config.gcc - add x86_64, same as i[34567]86.
i[34567]86-*-openbsd*)
tm_file="${tm_file} i386/unix.h i386/att.h dbxelf.h elfos.h"
