Re: HEADS UP: plan to switch many ports over to GCC 12 soon



Does the assembler also get updated with this? I'm asking because I
noticed when compiling pkgsrc package libdeflate-1.20 with gcc12 (from
pkgsrc) that the compiler generates vpdpbusd instructions (amd64) but
the assembler doesn't know those:

[ 58%] Building C object CMakeFiles/libdeflate_shared.dir/lib/zlib_decompress.c.o

... more of the same...

For building firefox, I had to pretend that __AVXVNNI__ wasn't #defined.
