[Bug target/48690] New: gcc-4.3.5 fails for target m68k
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48690
Summary: gcc-4.3.5 fails for target m68k
Product: gcc
Version: 4.3.5
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassig...@gcc.gnu.org

standalone version of fixunsxfdi() from libgcc2.c
Hi,
The 4.3.5 release fails to successfully compile libgcc. In particular the
fixunsxfdi() routine fails with an internal compiler error for -O1 & -O2. The
popcountdi2() routine fails with an internal compiler error for -Os.
This was tested using an x86 -> m68k cross compiler configured as such:
#!/bin/bash
set -x
optlevel="O1"
export CFLAGS="-${optlevel} -g -fomit-frame-pointer"
#--enable-secureplt \
#--enable-version-specific-runtime-libs \
#--with-gxx-include-dir= \
#--enable-languages=all,obj-c++ \
#--disable-debug \
BOOT_CFLAGS="$CFLAGS" \
CFLAGS_FOR_TARGET="$CFLAGS" \

--prefix=/opt/cross/q700/gcc-4.3.5-${optlevel}-c,c++ \
--target=m68k-netbsdelf1.6.1 \
--with-sysroot=/opt/cross/q700 \
--with-build-time-tools=/opt/cross/q700/binutils-2.16.1/bin \

--with-gmp=/opt/GMP-4.3.2 \
--with-mpfr=/opt/MPFR-2.4.2 \
--with-gnu-ld \
--with-gnu-as
set +x
gcc-4.2.4 seems ok.
