Package: gcc-16-powerpc-linux-gnu Version: 16.1.0-3cross1 Severity: normal Tags: ftbfs
powerpc and powerpc64 flavours used to unconditionally specify -many assembler option when invoking `as` binary. This way, `as' accepted mixed instructions. For example, when building openbios for ppc, we have: powerpc-linux-gnu-gcc -m32 -m604 ... start.S with previous versions of gcc, this resulted in as -a32 -mppc -many -mbig ... now with gcc-16.1.0, the -many is missing: as -a32 -mppc -mbig ... and `as` complains about unrecognized instructions such as clrldi, mtmsrd, ld, std, - which are 64bits and are valid for this CPU type. The same happens with powerpc64, which also omits -many now, so `as' rejects other instructions, such as hrfid or nap, and there, adding -many explicitly lets the build to continue. I don't know if this is an intended change or not, - especially since I know right to nothing about ppc assembly. But it feels like it is not intended. On Fedora, gcc-16.1.1 does pass -many unconditionally, as it were before. So it feels like only debian is broken currently. This issue breaks qemu build (#1143769). I can work around this by explicitly passing -Wa,-many in two places, but it feels wrong to do that. Thanks, /mjt
