* fix a bunch of partially ambiguous patterns on ARM. As anChris Lattner2010-03-083-35/+40
| | | | | | | | | | | | example, this: (set DPR:$dst, (fsub (fneg (fmul DPR:$a, DPR:$b)), DPR:$dstin)) is ambiguous because DPR contains both f64 and v2f32. tblgen currently accidentally picks f64 because it's first in the regclass. llvm-svn: 97955

* 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

* Whoops, the old LLVMWriteBitcodeToFileHandle closed the stream.Erick Tryzelaar2010-03-061-1/+1
| | | | | | Luckily this never was released. llvm-svn: 97857

| | | | | | | | | 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 Christopher2010-03-052-386/+357

* Better handling of dead super registers in LiveVariables. We used to do this:Jakob Stoklund Olesen2010-03-051-21/+21
| | | | | | | | | | | | | | | | | | | | | 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
