2013-02-06R600: Support for indirect addressing v4Tom Stellard
Only implemented for R600 so far. SI is missing implementations of a few callbacks used by the Indirect Addressing pass and needs code to handle frame indices. At the moment R600 only supports array sizes of 16 dwords or less. Register packing of vector types is currently disabled, which means that a vec4 is stored in T0_X, T1_X, T2_X, T3_X, rather than T0_XYZW. In order to correctly pack registers in all cases, we will need to implement an analysis pass for R600 that determines the correct vector width for each array. v2: - Add support for i8 zext load from stack. - Coding style fixes v3: - Don't reserve registers for indirect addressing when it isn't being used. - Fix bug caused by LLVM limiting the number of SubRegIndex declarations. v4: - Fix 64-bit defines git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174525 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-05Don't use MRI liveouts in R600.Jakob Stoklund Olesen
Something very strange is going on with the output registers in this target. Its ISelLowering code is inserting dangling CopyToReg nodes, hoping that those physregs won't get clobbered before the RETURN. This patch adds the output registers as implicit uses on RETURN instructions in the custom emission pass. I'd much prefer to have those CopyToReg nodes glued to the RETURNs, but I don't see how. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174400 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-05R600: improve inputs/interpolation handlingTom Stellard
Use one intrinsic for all sorts of interpolation. Use two separate unexpanded instructions to represent INTERP_XY and _ZW - this will allow to eliminate one part if it's not used. Track liveness of special interpolation regs instead of reserving them - this will allow to reuse those regs, lowering reg pressure.

2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project.
