* Re-committing the failed r97807 commit with changes to eliminate warnings.Wesley Peck2010-03-067-76/+207
| | | | llvm-svn: 97891
* Add verification of union types.Nick Lewycky2010-03-061-0/+9
| | | | llvm-svn: 97889
* Describe what's going on with mingw alloca and why do we need separate ↵Anton Korobeynikov2010-03-061-1/+9
| | | | | | instruction. llvm-svn: 97888
* Initial bits of ARMv4-only support.Anton Korobeynikov2010-03-066-29/+101
| | | | | | Patch by John Tytgat! llvm-svn: 97886
* Lower dynamic stack allocation on mingw32 to separate instruction.Anton Korobeynikov2010-03-064-20/+56
| | | | | | | We cannot use a normal call here since it has extra unmodelled side effects (it changes stack pointer). This should fix PR5292. llvm-svn: 97884
* make APFloat::toString be const.Chris Lattner2010-03-062-2/+2
| | | | llvm-svn: 97883
* disable this for mingw as well, we really need a 'has no dynamic linking' ↵Chris Lattner2010-03-061-1/+1
| | | | | | predicate. llvm-svn: 97882
* Do not use '&' prefix for globals when register base field is non-zero, ↵Anton Korobeynikov2010-03-066-27/+35
| | | | | | | | otherwise msp430-as will silently miscompile the code (TI's assembler report an error though). This fixes PR6349 llvm-svn: 97877
* Let the fallthrough handle whether or not we've changed anythingEric Christopher2010-03-061-1/+3
| | | | | | before we try to optimize. llvm-svn: 97876
* Migrate _chk call lowering from SimplifyLibCalls to InstCombine. StubEric Christopher2010-03-066-140/+132
| | | | | | | | out the remainder of the calls that we should lower in some way and move the tests to the new correct directory. Fix up tests that are now optimized more than they were before by -instcombine. llvm-svn: 97875
* Add static methods to handle Linkage Types.Rafael Espindola2010-03-061-20/+62
| | | | llvm-svn: 97871
* clean this up.Chris Lattner2010-03-061-6/+7
| | | | llvm-svn: 97870
* revert r97807, it introduced build warnings.Chris Lattner2010-03-066-257/+61
| | | | llvm-svn: 97869
* Thumb1 epilogue code generation needs to take into account that callee-savedJim Grosbach2010-03-061-4/+18
| | | | | | | registers may be restored via a pop instruction, not just a tRestore. This fixes nightly test 471.omnetep for Thumb1. llvm-svn: 97867
* Temporarily revert:Eric Christopher2010-03-062-26/+0
| | | | | | | | | | | | | Log: Transform @llvm.objectsize to integer if the argument is a result of malloc of known size. Modified: llvm/trunk/lib/Transforms/InstCombine/InstCombineCalls.cpp llvm/trunk/test/Transforms/InstCombine/objsize.ll It appears to be causing swb and nightly test failures. llvm-svn: 97866
* Fix another case where LSR was affected by debug info.Dale Johannesen2010-03-061-1/+12
| | | | llvm-svn: 97865
* Don't update physical register def.Evan Cheng2010-03-061-2/+3

* Transform @llvm.objectsize to integer if the argument is a result of malloc ↵Evan Cheng2010-03-062-0/+26
| | | | | | of known size. llvm-svn: 97860
* Add a LLVMWriteBitcodeToFD that exposes the raw_fd_ostream options.Erick Tryzelaar2010-03-066-10/+80
| | | | llvm-svn: 97858
* Whoops, the old LLVMWriteBitcodeToFileHandle closed the stream.Erick Tryzelaar2010-03-061-1/+1
| | | | | | Luckily this never was released. llvm-svn: 97857
* LLVMWriteBitcodeToFileHandle should work on all architectures now.Erick Tryzelaar2010-03-061-11/+0
| | | | llvm-svn: 97856
* Add some new bits of debug info handling. NoDale Johannesen2010-03-064-3/+142

* Don't emit global symbols into the (__TEXT,__ustring) section on Darwin. ThisCharles Davis2010-03-052-3/+2
| | | | | | | | | is a workaround for <rdar://problem/7672401/> (which I filed). This let's us build Wine on Darwin, and it gets the Qt build there a little bit further (so Doug says). llvm-svn: 97845
* Move SimplifyLibCalls's LibCall builders to a separate file so theyEric Christopher2010-03-053-386/+453
| | | | | | | | can be used in more places. Add an argument for the TargetData that most of them need. Update for the getInt8PtrTy() change. Should be no functionality change. llvm-svn: 97844
* Add support for an i8* type accessor.Eric Christopher2010-03-051-0/+4

* Better handling of dead super registers in LiveVariables. We used to do this:Jakob Stoklund Olesen2010-03-052-22/+22
| | | | | | | | | | | | | | | | | | | | | CALL ... %RAX<imp-def> ... [not using %RAX] %EAX = ..., %RAX<imp-use, kill> RET %EAX<imp-use,kill> Now we do this: CALL ... %RAX<imp-def, dead> ... [not using %RAX] %EAX = ... RET %EAX<imp-use,kill> By not artificially keeping %RAX alive, we lower register pressure a bit. The correct number of instructions for 2008-08-05-SpillerBug.ll is obviously 55, anybody can see that. Sheesh. llvm-svn: 97838
* We don't really care about correct register liveness information after theJakob Stoklund Olesen2010-03-052-4/+59
| | | | | | post-ra scheduler has run. Disable the verifier checks that late in the game. llvm-svn: 97837
* Avoid creating bad PHI instructions when BR is being const-folded.Jakob Stoklund Olesen2010-03-052-0/+44
| | | | llvm-svn: 97836
* Fix a case where LSR is sensitive to debug info.Dale Johannesen2010-03-051-0/+9

* fix bss section printing for cell, patch by Kalle Raiskila!Chris Lattner2010-03-052-0/+8
| | | | llvm-svn: 97814
* fix PR6512, a case where instcombine would incorrectly merge loadsChris Lattner2010-03-052-0/+42
| | | | | | from different addr spaces. llvm-svn: 97813
* Reworking the stack layout that the MicroBlaze backend generates.Wesley Peck2010-03-056-61/+257
| | | | | | | | | | | The MicroBlaze backend was generating stack layouts that did not conform correctly to the ABI. This update generates stack layouts which are closer to what GCC does. Variable arguments support was added as well but the stack layout for varargs has not been finalized. llvm-svn: 97807
* Adding MBlaze to cmake target list.Wesley Peck2010-03-051-0/+1
| | | | llvm-svn: 97806
* Fix PR6503. This turned into a much more interesting and nasty bug. Various Chris Lattner2010-03-054-139/+122
| | | | | | | | | | | parts of the cmp|cmp and cmp&cmp folding logic wasn't prepared for vectors (unrelated to the bug but noticed while in the code) and the code was *definitely* not safe to use by the (cast icmp)|(cast icmp) handling logic that I added in r95855. Fix all this up by changing the various routines to more consistently use IRBuilder and not pass in the I which had the wrong type. llvm-svn: 97801
* make these less sensitive to temporary naming.Chris Lattner2010-03-053-15/+15
| | | | llvm-svn: 97799

* Fix an oops in x86 sibcall optimization. If the ByVal callee argument is ↵Evan Cheng2010-03-052-8/+35
| | | | | | itself passed as a pointer, then it's obviously not safe to do a tail call. llvm-svn: 97797
* If LD_LIBRARY_PATH is set in the system environment, use it.Duncan Sands2010-03-051-0/+1
| | | | llvm-svn: 97796
* simplify some functions and make them work with vectorChris Lattner2010-03-051-62/+25

* fix a nice subtle reassociate bug which would only occurChris Lattner2010-03-052-7/+34
| | | | | | | in a very specific use pattern embodied in the carefully reduced testcase. llvm-svn: 97794
* Move GetStringLength and helper from SimplifyLibCalls to ValueTracking.Eric Christopher2010-03-053-124/+133
| | | | | | No functionality change. llvm-svn: 97793

* Fix PR6497, a bug where we'd fold a load into an addcChris Lattner2010-03-052-0/+27
| | | | | | | | | | | node which has a flag. That flag in turn was used by an already-selected adde which turned into an ADC32ri8 which used a selected load which was chained to the load we folded. This flag use caused us to form a cycle. Fix this by not ignoring chains in IsLegalToFold even in cases where the isel thinks it can. llvm-svn: 97791
