There is some code that does the right thing, but it brokenly only preserves these bits when the thread is not in 64-bit mode (i.e. when it doesn't matter). The attached patch unconditionally enables this code when TARGET_PPC64 is set, per the ISA spec, which fixes early boot failures trying to start FreeBSD/powerpc64 under qemu. \ No newline at end of file |
