* Fix getNode to allow a vector for the shift amount for shifts of vectors.Mon P Wang2008-12-094-9/+44
| | | | | | | | Fix the shift amount when unrolling a vector shift into scalar shifts. Fix problem in getShuffleScalarElt where it assumes that the input of a bit convert must be a vector. llvm-svn: 60740
* Fix a really subtle off-by-one bug that Duncan noticed with valgrindChris Lattner2008-12-091-1/+1
| | | | | | on test/CodeGen/Generic/2007-06-06-CriticalEdgeLandingPad. llvm-svn: 60739
* CellSPU:Scott Michel2008-12-091-2/+5
| | | | | | | | - Change default scheduling preference to list-burr, which produces somewhat better code than the default. Could also use list-tdrr, but need to ask dev list about the appropriate handy mnemonic before commiting. llvm-svn: 60738
* Add initial support for fast-isel of the [SU]ADDO intrinsics. It isn'tBill Wendling2008-12-091-7/+84
| | | | | | | | | | | | | | | | | | | complete. For instance, it lowers the common case into this less-than-optimal code: addl %ecx, %eax seto %cl testb %cl, %cl jne LBB1_2 ## overflow instead of: addl %ecx, %eax jo LBB1_2 ## overflow That will come in a future commit. llvm-svn: 60737
* Fix the name of ISD::TokenFactor in a comment. Thanks Gabor!Dan Gohman2008-12-091-1/+1

* Fix a couple of mistaken switch case fall-throughs. Thanks to BillDan Gohman2008-12-081-0/+2
| | | | | | for spotting these! llvm-svn: 60728
* Actually test something. Use PR3170 test case.Devang Patel2008-12-081-36/+25

* remove DebugIterations option. Despite the accusations, Chris Lattner2008-12-081-14/+1
| | | | | | | jump threading has been shown to only expose problems not have bugs itself. I'm sure it's completely bug free! ;-) llvm-svn: 60725
* Re-apply 60689 now my head is screwed on right.Evan Cheng2008-12-081-0/+2

* Fix the top-level comments, and fix some 80-column violations.Dan Gohman2008-12-081-7/+9
| | | | llvm-svn: 60707
* Move the conversion to intptr_t to a separate statement. ThisDan Gohman2008-12-081-2/+3
| | | | | | avoids GCC's warning even on 64-bit hosts. llvm-svn: 60706
* Revert 60689. It caused many regressions on Darwin targets.Dan Gohman2008-12-081-3/+1

* Factor out the code for sign-extending/truncating gep indicesDan Gohman2008-12-084-26/+57
| | | | | | | | | and use it in x86 address mode folding. Also, make getRegForValue return 0 for illegal types even if it has a ValueMap for them, because Argument values are put in the ValueMap. This fixes PR3181. llvm-svn: 60696
* add another level of caching for non-local pointer queries, keepingChris Lattner2008-12-082-8/+34
| | | | | | | | | track of whether the CachedNonLocalPointerInfo for a block is specific to a block. If so, just return it without any pred scanning. This is good for a 6% speedup on GVN (when it uses this lookup method, which it doesn't right now). llvm-svn: 60695

* introduce a new RoundUpAlignment helper function, use it to Chris Lattner2008-12-082-37/+40

* Speed up getABITypeSize by turning a i64 mul and div into anChris Lattner2008-12-081-2/+6
| | | | | | | | | AND. This is speedup on any reasonable target, but particularly on 32-bit targets where this often turns into a libcall like udivdi3. We know that alignments are a power of two but the compiler doesn't. llvm-svn: 60688

* Generalize bugpoint's concept of a "safe" backend, and add optionsDan Gohman2008-12-085-63/+155
| | | | | | | | | | | | | | to allow the "safe" backend to be run with a different path, and/or with different command-line options. This enables the following use cases: - bugpoint llc against an llc command from a different build - bugpoint llc against the same llc with different command-line options - and more... Also, document the existing "custom" interpreter options. llvm-svn: 60681

* Use bool instead of int, now that it no longer evokes a warning.Dan Gohman2008-12-071-1/+1
| | | | llvm-svn: 60678
* Use intptr_t instead of unsigned here, which is more appropriateDan Gohman2008-12-071-1/+1
| | | | | | | in a really obscure way, but more importantly has the side effect of avoiding a GCC warning in the case that IntType is bool. llvm-svn: 60677
