The transformation is not considered profitable on ia32, that's why it doesn't take place. Maybe that's a bug in itself, but it's not a regression, and not something to be noisy about. Regstrapped on x86_64-linux-gnu, also tested with gcc-13 on i686- and x86_64-. Ok to install? (Richi, is the non-optimization choice on ia32 something unexpected that ought to be looked into? I could file a PR, and maybe even look into it a bit further.) for gcc/testsuite/ChangeLog * gcc.dg/tree-ssa/scev-3.c: xfail on ia32. * gcc.dg/tree-ssa/scev-5.c: Likewise.
