Hi,
Qt doesn't compile for arm-eabi w/ g++ 4.1.1. The problem manifests like
that:
ccache arm-angstrom-linux-gnueabi-g++ -march=armv5te -mtune=xscale -c
-pipe -isystem/local/pkg/oe/spitz/tmp/staging/arm-angstr
om-linux-gnueabi/include -fexpensive-optimizations -fomit-frame-pointer

The offending source is in qatomic.h:
inline char q_atomic_swp(volatile char *ptr, char newval)
{
register int ret;
asm volatile("swpb %2,%1,[%0]"
: "=r"(ret)
: "r"(newval), "r"(ptr)
: "cc", "memory");
return ret;
}
Looks like the new toolchain has a more strict asm checking -- arm asm
expert with an idea how to repair that?
