* teach tblgen to be more aggressive when factoring CheckType nodes.Chris Lattner2010-03-071-29/+95
| | | | | | | | | | | | | | | | | | | | | | | Now it will factor things like this: CheckType i32 ... CheckOpcode ISD::AND CheckType i64 ... into: SwitchType: i32: ... i64: CheckOpcode ISD::AND ... This shrinks hte table by a few bytes, nothing spectacular. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97908 91177308-0d34-0410-b5e6-96231b3b80d8

* Teach lit to honor conditional directives. The syntax is:John McCall2010-03-042-3/+30
| | | | | | | | | | | | | | | | | | IF(condition(value)): If the value satisfies the condition, the line is processed by lit; otherwise it is skipped. A test with no unignored directives is resolved as Unsupported. The test suite is responsible for defining conditions; conditions are unary functions over strings. I've defined two conditions in the LLVM test suite, TARGET (with values like those in TARGETS_TO_BUILD) and BINDING (with values like those in llvm_bindings). So for example you can write: IF(BINDING(ocaml)): RUN: %blah %s -o - and the RUN line will only execute if LLVM was configured with the ocaml bindings. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97726 91177308-0d34-0410-b5e6-96231b3b80d8

This also improves comments in the tables and shrinks the table a bit, now down to 80506 bytes for x86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97703 91177308-0d34-0410-b5e6-96231b3b80d8

* Rewrite chain handling validation and input TokenFactor handlingChris Lattner2010-03-024-58/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | stuff now that we don't care about emulating the old broken behavior of the old isel. This eliminates the 'CheckChainCompatible' check (along with IsChainCompatible) which did an incorrect and inefficient scan *up* the chain nodes which happened as the pattern was being formed and does the validation at the end in HandleMergeInputChains when it forms a structural pattern. This scans "down" the graph, which means that it is quickly bounded by nodes already selected. This also handles token factors that get "trapped" in the dag. Removing the CheckChainCompatible nodes also shrinks the generated tables by about 6K for X86 (down to 83K). There are two pieces remaining before I can nuke PreprocessRMW: 1. I xfailed a test because we're now producing worse code in a case that has nothing to do with the change: it turns out that our use of MorphNodeTo will leave dead nodes in the graph which (depending on how the graph is walked) end up causing bogus uses of chains and blocking matches. This is really bad for other reasons, so I'll fix this in a follow-up patch. 2. CheckFoldableChainNode needs to be improved to handle the TF. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97539 91177308-0d34-0410-b5e6-96231b3b80d8
