Segher Boessenkool <segher at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #2 from Segher Boessenkool <segher at gcc dot gnu.org> --- This is not a bug. This change was made in r267280: """ c++, asm: Do not handle any asm-qualifiers in top-level asm Previously, "volatile" was allowed. Changing this simplifies the code, makes things more regular, and makes the C and C++ frontends handle this the same way. """ https://gcc.gnu.org/ml/gcc-patches/2018-12/msg00605.html
