Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |aoliva at gcc dot gnu.org Target Milestone|--- |6.0 --- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- We fail to have a default-def for a PARM_DECL in this case. The PARM_DECL was created by function versioning so eventually the code that makes sure we always have a default def for PARM_DECLs doesn't trigger (the function is versioned when already in SSA form).
