R600/SI: Add test that fails due to requiring i64 mul for pointers llvm-svn: 194433
2013-11-12 07:31:02 +08:00
; XFAIL: *
R600/SI: Custom lower SI_IF and SI_ELSE to avoid machine verifier errors SI_IF and SI_ELSE are terminators which also produce a value. For these instructions ISel always inserts a COPY to move their value to another basic block. This COPY ends up between SI_(IF|ELSE) and the S_BRANCH* instruction at the end of the block. This breaks MachineBasicBlock::getFirstTerminator() and also the machine verifier which assumes that terminators are grouped together at the end of blocks. To solve this we coalesce the copy away right after ISel to make sure there are no instructions in between terminators at the end of blocks. llvm-svn: 207591
