Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Ever confirmed|0 |1 Last reconfirmed| |2023-05-08 Status|UNCONFIRMED |NEW Target Milestone|--- |14.0 --- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> --- The issue is xstormy has a 16bit int type and both 1 and 0 are getting assigned 'int'. Since you #define int you need to wrap all literals with _Literal (int) ... and of course 2147483647 won't fit (thus dg-require-effective-target int32plus?)
