* Replace a hand rolled loop with a lovely StringRef helper we have theseChandler Carruth2012-02-211-4/+1
| | | | | | days. No functionality changed. llvm-svn: 151048
* Pull the parsing helper functions out of the Triple interface entirely.Chandler Carruth2012-02-211-89/+90
| | | | | | | | | | | | | They're private static methods but we can just make them static functions in the implementation. It makes the implementations a touch more wordy, but takes another chunk out of the header file. Also, take the opportunity to switch the names to the new coding conventions. No functionality changed here. llvm-svn: 151047
* Clean up comments that I missed when changing the triple representation.Chandler Carruth2012-02-211-10/+7
| | | | | | | | Somehow, I even missed the ones I wrote just the other day... Thanks to Matt for the code review. llvm-svn: 151045
* Clear virtual registers after they are no longer referenced.Andrew Trick2012-02-218-6/+42
| | | | | | | | | | | | | Passes after RegAlloc should be able to rely on MRI->getNumVirtRegs() == 0. This makes sharing code for pre/postRA passes more robust. Now, to check if a pass is running before the RA pipeline begins, use MRI->isSSA(). To check if a pass is running after the RA pipeline ends, use !MRI->getNumVirtRegs(). PEI resets virtual regs when it's done scavenging. PTX will either have to provide its own PEI pass or assign physregs. llvm-svn: 151032

* Switch the llvm::Triple class to immediately parse the triple string onChandler Carruth2012-02-212-24/+17
| | | | | | | | | construction. Simplify its interface, implementation, and users accordingly as there is no longer an 'uninitialized' state to check for. Also, fixes a bug lurking in the interface as there was one method that didn't correctly check for initialization. llvm-svn: 151024

This patch * removes the FIXME about adding the assert. * adds a comment explaining hy we don't have one. * removes a broken logic that only works for some callers and is not needed since r150884. * adds an assert to caller that would have caught the bug fixed by r150884. llvm-svn: 151015

* Fix machine-cp by having it to check sub-register indicies. e.g.Evan Cheng2012-02-202-3/+27
| | | | | | | | | | | | ecx = mov eax al = mov ch The second copy is not a nop because the sub-indices of ecx,ch is not the same of that of eax/al. Re-enabled machine-cp. PR11940 llvm-svn: 151002

* InstCombine: Make OptimizePointerDifference more aggressive.Benjamin Kramer2012-02-201-27/+27
| | | | | | | | | - Ignore pointer casts. - Also expand GEPs that aren't constantexprs when they have one use or only constant indices. - We now compile "&foo[i] - &foo[j]" into "i - j". llvm-svn: 150961

If we do, we can end up with inst1 --------------- < Insertion point dbg inst new inst instead of the desired inst1 new inst --------------- < Insertion point dbg inst Another option would be for InsertNoopCastOfTo (or its callers) to move the insertion point and we would end up with inst1 dbg inst new inst --------------- < Insertion point but that complicates the callers.
