Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> --- inline-asm is duplicated via doing inlining. THIS IS NOT A GCC BUG. If you want to define a symbol like this, use either top level inline-asm or the .s file. ALSO THIS IS DOCUMENTED: Under certain circumstances, GCC may duplicate (or remove duplicates of) your assembly code when optimizing. This can lead to unexpected duplicate symbol errors during compilation if your assembly code defines symbols or labels. --- CUT --- >From https://gcc.gnu.org/onlinedocs/gcc-9.1.0/gcc/Basic-Asm.html#Basic-Asm .
