of all sizes from i1 to i256. The code is not always that great, for example (x86) movw %di, %ax movw %ax, i17_s where the store could be directly from %di. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@53677 91177308-0d34-0410-b5e6-96231b3b80d8

2008-06-10Fix some more quoting issues in RUN lines, this time regarding unintendedMatthijs Kooijman
variable expansions involving the $ character. This fixes 4 tests that were not running properly before. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52183 91177308-0d34-0410-b5e6-96231b3b80d8
2008-06-10For all RUN lines starting with "not", redirect stderr to /dev/null so testsMatthijs Kooijman
don't fail when (expected) error output is produced. This fixes 17 tests. While I was there, I also made all RUN lines of the form "not llvm-as..." a bit more consistent, they now all redirect stderr and stdout to /dev/null and use input redirect to read their input. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52174 91177308-0d34-0410-b5e6-96231b3b80d8

2008-04-25Remove the code from CodeGenPrepare that moved getresult instructionsDan Gohman
to the block that defines their operands. This doesn't work in the case that the operand is an invoke, because invoke is a terminator and must be the last instruction in a block. Replace it with support in SelectionDAGISel for copying struct values into sequences of virtual registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50279 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-26Fix isNegatibleForFree to not return true for ConstantFP nodes Chris Lattner
after legalize. Just because a constant is legal (e.g. 0.0 in SSE) doesn't mean that its negated value is legal (-0.0). We could make this stronger by checking to see if the negated constant is actually legal post negation, but it doesn't seem like a big deal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47591 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-13Teach LegalizeTypes how to expand and promote CTLZ,Duncan Sands
CTTZ and CTPOP. The expansion code differs from that in LegalizeDAG in that it chooses to take the CTLZ/CTTZ count from the Hi/Lo part depending on whether the Hi/Lo value is zero, not on whether CTLZ/CTTZ of Hi/Lo returned 32 (or whatever the width of the type is) for it. I made this change because the optimizers may well know that Hi/Lo is zero and exploit it. The promotion code for CTTZ also differs from that in LegalizeDAG: it uses an "or" to get the right result when the original value is zero, rather than using a compare and select. This also means the value doesn't need to be zero extended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47075 91177308-0d34-0410-b5e6-96231b3b80d8

2008-02-04Crashed the new type legalizer. Not likely to catchDuncan Sands
any bugs in the future since to get the crash you also need hacked in fake libcall support (which creates odd but legal trees), but since adding it doesn't hurt... Thanks to Chris for this ultimately reduced version. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@46706 91177308-0d34-0410-b5e6-96231b3b80d8
2008-01-26Fix some bugs in SimplifyNodeWithTwoResults where it would call deletenode to Chris Lattner
delete a node even if it was not dead in some cases. Instead, just add it to the worklist. Also, make sure to use the CombineTo methods, as it was doing things that were unsafe: the top level combine loop could touch dangling memory.

2007-12-25GC poses hazards to the inliner. Consider:Gordon Henriksen
define void @f() { ... call i32 @g() ... } define void @g() { ... } The hazards are: - @f and @g have GC, but they differ GC. Inlining is invalid. This may never occur. - @f has no GC, but @g does. g's GC must be propagated to @f. The other scenarios are safe: - @f and @g have the same GC. - @f and @g have no GC. - @g has no GC. This patch adds inliner checks for the former two scenarios. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45351 91177308-0d34-0410-b5e6-96231b3b80d8
