Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Last reconfirmed| |2023-05-24 Ever confirmed|0 |1 Status|UNCONFIRMED |NEW --- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> --- I think a compiler built for x86_64-pc-linux-gnu implicitly has --with-arch=x86-64 and --with-arch_32=x86-64, which means it assumes the 32-bit code will actually run on an x86_64 CPU. Which definitely doesn't match the docs.
