This patch replaces the control flow handling with a new pass which structurize the graph before transforming it to machine instruction. This has a couple of different advantages and currently fixes 20 piglit tests without a single regression. It is now a general purpose transformation that could be not only be used for SI/R6xx, but also for other hardware implementations that use a form of structurized control flow. v2: further cleanup, fixes and documentation Patch by: Christian König Signed-off-by: Christian König <deathsimple@vodafone.de> Reviewed-by: Tom Stellard <thomas.stellard@amd.com> Tested-by: Michel Dänzer <michel.daenzer@amd.com> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170591 91177308-0d34-0410-b5e6-96231b3b80d8
