cmd/objdump: x86 disassembler does not recognize PDEPQ #25617
What version of Go are you using (
@mmcloughlin, that's my understanding that it's better to re-generate disassembler than to manually fix all issues (there are potentially a lots of them). It's possible to patch it, but decoder does not understand, for example, all recently added AVX-512 instructions, so it's not a matter of dozens, but hundreds of instructions.
The main problem is that updated x86.csv generator is on halt until some format questions are resolved. The encoder tables (for assembler) are generated from XED tables directly right now. It is possible to generate decoder tables from that too, but this would require discussion as well.
