2006-07-21Removed a hack intended to allow (store (op (load))) folding. Will handle ↵Evan Cheng
this with preprocessing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29258 91177308-0d34-0410-b5e6-96231b3b80d8

2006-07-16Parameterize target node ValueType to allow more sharing of emit functions.Evan Cheng
Also reduce the number of arguments passed to emit functions and removed a hack. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29160 91177308-0d34-0410-b5e6-96231b3b80d8
2006-07-15Reduce instruction selection code size and stack frame size by factoringEvan Cheng
code that emit target specific nodes into emit functions that are uniquified and shared among selection routines. e.g. This reduces X86ISelDAGToDAG.o (release) from ~2M to ~1.5M. Stack frame size of Select_store from ~13k down to ~8k. This is the first step. Further work to enable more sharing will follow. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29158 91177308-0d34-0410-b5e6-96231b3b80d8

2006-06-29Ugly hack! Add helper functions InsertInFlightSetEntry andEvan Cheng
RemoveInFlightSetEntry. They are used in place of direct set operators to reduce instruction selection function stack size. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28987 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-20Fix an error message regression. Print:Chris Lattner
LI8: (LI8:i64 (imm:i64):$imm) instead of: LI8: (LI8:MVT::i64 (imm:MVT::i64):$imm) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28868 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-20Don't require src/dst patterns to be able to fully resolve their types,Chris Lattner
because information about one can help refine the other. This allows us to write: def : Pat<(i32 (extload xaddr:$src, i8)), (LBZX xaddr:$src)>; as: def : Pat<(extload xaddr:$src, i8), (LBZX xaddr:$src)>; because tblgen knows LBZX returns i32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28865 91177308-0d34-0410-b5e6-96231b3b80d8
2006-06-20Make sure to use the result of the pattern to infer the result type of theChris Lattner
instruction, and the result type of the instruction to refine the pattern. This allows us to write things like this: def : Pat<(v2i64 (bitconvert (v16i8 VR128:$src))), (v2i64 VR128:$src)>; as: def : Pat<(v2i64 (bitconvert (v16i8 VR128:$src))), (VR128:$src)> and fixes a ppc64 issue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28863 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-25Can't trust NodeDepth when checking for possibility of load folding creatingEvan Cheng
a cycle. This increase the search space and will increase compile time (in practice it appears to be small, e.g. 176.gcc goes from 62 sec to 65 sec) that will be addressed later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28476 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-25Fixed a really ugly bug. The TableGen'd isel is not freeing the "inflight set"Evan Cheng
correctly. That is causing non-deterministic behavior (and possibly preventing some load folding from happening). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28458 91177308-0d34-0410-b5e6-96231b3b80d8
2006-05-19Now that iPTR is a fully resolved type. We end up losing the type check forEvan Cheng
patterns that look like this: def : Pat<(i32 (X86Wrapper tconstpool :$dst)), (MOV32ri tconstpool :$dst)>; InsertOneTypeCheck should copy the type from the resolved pattern to the unresolved one as long as there types are different. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28389 91177308-0d34-0410-b5e6-96231b3b80d8

2006-05-10Watch out for the following case:Evan Cheng
1. Use expects a chain output. 2. Node is expanded into multiple target ops. 3. One of the inner node produces a chain, the outer most one doesn't. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28209 91177308-0d34-0410-b5e6-96231b3b80d8

2006-04-28When isel'ing a node, mark its operands "InFlight" before selecting them. TheseEvan Cheng

x86 and ppc for 100% dense switch statements when relocations are non-PIC. This support will be extended and enhanced in the coming days to support PIC, and less dense forms of jump tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27947 91177308-0d34-0410-b5e6-96231b3b80d8

2006-03-24Change approach so that we get codegen for free for intrinsics. With this,Chris Lattner
intrinsics that don't take pointer arguments now work. For example, we can compile this: int test3( __m128d *A) { return _mm_movemask_pd(*A); } int test4( __m128 *A) { return _mm_movemask_ps(*A); } to this: _test3: movl 4(%esp), %eax movapd (%eax), %xmm0 movmskpd %xmm0, %eax ret _test4: movl 4(%esp), %eax movaps (%eax), %xmm0 movmskps %xmm0, %eax ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27090 91177308-0d34-0410-b5e6-96231b3b80d8
