I've tried to reproduce the tattr FAILs reported in https://gcc.gnu.org/pipermail/gcc-testresults/2020-September/608760.html in a cross-compiler (with #define HAVE_AS_MACHINE_MACHINEMODE 1 ), but couldn't, neither the ICEs nor the scan-assembler failures. Anyway, could you do a side-by-side debugging of one of those failures before/after my change and see what behaves differently? Jakub
