* Minor optimization:Evan Cheng2009-03-011-29/+237
| | | | | | | | | | | Look for situations like this: %reg1024<def> = MOV r1 %reg1025<def> = MOV r0 %reg1026<def> = ADD %reg1024, %reg1025 r0 = MOV %reg1026 Commute the ADD to hopefully eliminate an otherwise unavoidable copy. llvm-svn: 65752

* Fix a pretty awesome bug that only happened in a strange case with anonymousChris Lattner2009-03-011-8/+11

| | | | | | | | | | | | | type opaque ; type %0 %C = type { %0, %0 } instead of: %C = type { opaque, opaque } when appropriate. llvm-svn: 65742
* Fix a long-standing bug and misfeature of the disassembler: when dealing with a Chris Lattner2009-03-011-12/+122
| | | | | | | | | | | | | | stripped .bc file, it didn't make any attempt to try to reuse anonymous types. This causes an amazing type explosion due to types getting duplicated everywhere they are referenced and other problems. This also caused correctness issues, because opaque types are unique for each time they are uttered in the file. This means that stripping a .bc file could produce a .ll file that could not be assembled (e.g. 2009-02-28-StripOpaqueName.ll). This patch fixes both of these issues. llvm-svn: 65738

* Introduce a new technique for merging BasicBlock with Instruction sentinel ↵Gabor Greif2009-02-271-34/+0
| | | | | | | | | by superposition. This looks dangerous, but isn't because the sentinel is accessed in special way only, namely the Next and Prev fields of it, and these are guaranteed to exist. llvm-svn: 65626

* Alignment values for i64 and f64 on ppc64 were wrong,Dale Johannesen2009-02-271-1/+3
| | | | | | | | possibly for the reason suggested by the comment. No wonder it didn't work very well. This unblocks bootstrap with assertions on ppc. llvm-svn: 65601

* If an available register falls through to a succ block, unset the last kill. ↵Evan Cheng2009-02-261-37/+76
| | | | | | Sorry, it's impossible to reduce a sensible test case. It basically requires the moon and stars to align in order to cause a failure. llvm-svn: 65497

* Fix big-endian codegen bug. We're splitting upDale Johannesen2009-02-251-1/+2
| | | | | | | | | | | overly long ints, e.g. i96, into pieces at PHIs and the nodes that feed into them; however big-endian reverses the order of the pieces (for some reason), and wasn't doing it the same way on both sides, so the pieces didn't match and runtime failures ensued. Fixes 188.ammp and sqlite3 on ppc32. llvm-svn: 65481
