* Fix PR16110: Handle DBG_VALUE in ConnectedVNInfoEqClasses::Distribute().Jakob Stoklund Olesen2013-05-232-2/+123
| | | | | | | | | | | | Now that the LiveDebugVariables pass is running *after* register coalescing, the ConnectedVNInfoEqClasses class needs to deal with DBG_VALUE instructions. This only comes up when rematerialization during coalescing causes the remaining live range of a virtual register to separate into two connected components. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182592 91177308-0d34-0410-b5e6-96231b3b80d8

* Recognize ValueType operands in source patterns for fast-isel.Bill Schmidt2013-05-221-3/+7
| | | | | | | | | | | | | | | | | | | | | | Currently the fast-isel table generator recognizes registers, register classes, and immediates for source pattern operands. ValueType operands are not recognized. This is not a problem for existing targets with fast-isel support, but will not work for targets like PowerPC and SPARC that use types in source patterns. The proposed patch allows ValueType operands and treats them in the same manner as register classes. There is no convenient way to map from a ValueType to a register class, but there's no need to do so. The table generator already requires that all types in the source pattern be identical, and we know the register class of the output operand already. So we just assign that register class to any ValueType operands we encounter. No functional effect on existing targets. Testing deferred until the PowerPC target implements fast-isel. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182512 91177308-0d34-0410-b5e6-96231b3b80d8
* Change some PowerPC PatLeaf definitions to ImmLeaf for fast-isel.Bill Schmidt2013-05-222-17/+19
| | | | | | | | | | | | | | | | | | | Using PatLeaf rather than ImmLeaf when defining immediate predicates prevents simple patterns using those predicates from being recognized for fast instruction selection. This patch replaces the immSExt16 PatLeaf predicate with two ImmLeaf predicates, imm32SExt16 and imm64SExt16, allowing a few more patterns to be recognized (ADDI, ADDIC, MULLI, ADDI8, and ADDIC8). Using the new predicates does not help for LI, LI8, SUBFIC, and SUBFIC8 because these are rejected for other reasons, but I see no reason to retain the PatLeaf predicate. No functional change intended, and thus no test cases yet. This is preliminary work for enabling fast-isel support for PowerPC. When that support is ready, we'll be able to test this function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182510 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | | | | | | | The earlier change list introduced the following inst combines: B * (uitofp i1 C) —> select C, B, 0 A * (1 - uitofp i1 C) —> select C, 0, A select C, 0, B + select C, A, 0 —> select C, A, B Together these 3 changes would simplify : A * (1 - uitofp i1 C) + B * uitofp i1 C down to : select C, B, A In practice we found that the first two substitutions can have a negative effect on performance, because they reduce opportunities to use FMA contractions; between the two options FMAs are often the better choice. This change list amends the previous one to enable just these inst combines: select C, B, 0 + select C, 0, A —> select C, B, A A * (1 - uitofp i1 C) + B * uitofp i1 C —> select C, B, A git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182499 91177308-0d34-0410-b5e6-96231b3b80d8

* [SystemZ] Fix thinko in long branch passRichard Sandiford2013-05-221-26/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The original version of the pass could underestimate the length of a backward branch in cases like: alignment to N bytes or more ... relaxable branch A ... foo: (aligned to M<N bytes) ... bar: (aligned to N bytes) ... relaxable branch B to foo We don't add any misalignment gap for "bar" because N bytes of alignment had already been reached earlier in the function. In this case, assuming that A is relaxed can push "foo" closer to "bar", and make B appear to be in range. Similar problems can occur for forward branches. I don't think it's possible to create blocks with mixed alignments as things stand, not least because we haven't yet defined getPrefLoopAlignment() for SystemZ (that would need benchmarking). So I don't think we can test this yet. Thanks to Rafael Espíndola for spotting the bug. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182460 91177308-0d34-0410-b5e6-96231b3b80d8
