Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8 |

To-do ----- * Keep the address of the constant pool in a register instead of forming its address all of the time. * We can fold small constant offsets into the %hi/%lo references to constant pool addresses as well. * When in V9 mode, register allocate %icc[0-3]. * Add support for isel'ing UMUL_LOHI instead of marking it as Expand. * Emit the 'Branch on Integer Register with Prediction' instructions. It's not clear how to write a pattern for this though: float %t1(int %a, int* %p) { %C = seteq int %a, 0 br bool %C, label %T, label %F T: store int 123, int* %p br label %F F: ret float undef } codegens to this: t1: save -96, %o6, %o6 1) subcc %i0, 0, %l0 1) bne .LBBt1_2 ! F nop .LBBt1_1: ! T or %g0, 123, %l0 st %l0, [%i1] .LBBt1_2: ! F restore %g0, %g0, %g0 retl nop 1) should be replaced with a brz in V9 mode. * Same as above, but emit conditional move on register zero (p192) in V9 mode. Testcase: int %t1(int %a, int %b) { %C = seteq int %a, 0 %D = select bool %C, int %a, int %b ret int %D } * Emit MULX/[SU]DIVX instructions in V9 mode instead of fiddling with the Y register, if they are faster. * Codegen bswap(load)/store(bswap) -> load/store ASI * Implement frame pointer elimination, e.g. eliminate save/restore for leaf fns. * Fill delay slots * Implement JIT support
