The highregisters aren't available as separate 32-bit registers on z10,so subreg_h32 can't be used on a GR64 there.I've normally been testing with z196 and with -O3 and so hadn't noticedthis until now.llvm-svn: 195473 List of files: /llvm-project-15.0.7/llvm/test/CodeGen/SystemZ/int-cmp-47.ll Fri, 22 Nov 2013 17:28:28 +0000 Richard Sandiford <rsandifo@linux.vnet.ibm.com> http://172.16.0.5:8080/history/llvm-project-15.0.7/llvm/test/CodeGen/SystemZ/int-cmp-47.ll#030c1657 [SystemZ] Try to fold shifts into TMxxE.g.
