* R600/SI: cleanup literal handling v3Christian Konig2013-02-161-5/+5
| | | | | | | | | | | | | | | | | Seems to be allot simpler, and also paves the way for further improvements. v2: rebased on master, use 0 in BUFFER_LOAD_FORMAT_XYZW, use VGPR0 in dummy EXP, avoid compiler warning, break after encoding the first literal. v3: correctly use V_ADD_F32_e64 This is a candidate for the stable branch.

* R600: New control flow for SI v2Tom Stellard2012-12-191-89/+190
| | | | | | | | | | | | | | | | | | | | | 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
