While it does feel familiar, it is slightly different. https://godbolt.org/z/Rme4Zg That case was both compilers validating the inline asm, yet generating assembly that the assembler would choke on. This case is validation in the front end failing. Side note: would you mind sending a review by tag for v5 of that patch if you think it's good to go? It does fix a regression I'd prefer didn't ship in 5.7. -- Thanks, ~Nick Desaulniers
