--- Comment #3 from gcc at mag32 dot net ---
I am seeing a similar issue when building target CR16 with GCC 4.8.2. Here are
some details:
Exact version of GCC? 4.8.2
System type? ArchLinux (Linux arch-mago 3.11.6-1-ARCH #1 SMP PREEMPT Fri Oct 18
23:22:36 CEST 2013 x86_64 GNU/Linux)
The GCC used (xgcc) is a cross-compiled version for the CR16 target. This issue
triggers when I'm trying to build GCC 4.8.2 for CR16. My host GCC is also
4.8.2. The configure flags used are:
../configure --prefix=/usr/lib/cr16-unknown-elf --bindir=/usr/bin \
--with-sysroot=/usr/lib/cr16-unknown-elf \
--target=/usr/lib/cr16-unknown-elf --without-headers --enable-languages=c \
--with-newlib --disable-libssp --disable-threads --disable-nls \
--disable-shared --disable-multilib --disable-decimal-float \
--disable-libgomp --disable-libmudflap
Commandline used to trigger the bug? (This gets executed by the GCC makefile)
