| | | | | | | | | | | | | | | | | | | | | | | | | | | | the cast. 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. This fixes PR12018 (and firefox's build). llvm-svn: 150884

* Fix ARMBaseInstrInfo::getInstrLatency for calls.Jakob Stoklund Olesen2012-02-171-1/+1
| | | | | | Calls always clobber CPSR. llvm-svn: 150831
* Transfer regmasks to MRI.Jakob Stoklund Olesen2012-02-173-13/+7
| | | | | | | | | MRI keeps track of which physregs have been used. Make sure it gets updated with all the regmask-clobbered registers. Delete the closePhysRegsUsed() function which isn't necessary. llvm-svn: 150830
* Calls and invokes with the new clang.arc.no_objc_arc_exceptionsDan Gohman2012-02-171-6/+47
| | | | | | | | metadata may still unwind, but only in ways that the ARC optimizer doesn't need to consider. This permits more aggressive optimization. llvm-svn: 150829
* Refactor 'handleMove' code in live intervals. Clients of LiveIntervals won't seeLang Hames2012-02-171-211/+245
| | | | | | | | | any changes. Internally this adds a private inner class HMEditor, to LiveIntervals. HMEditor provides an API for updating live intervals when code is moved or bundled. llvm-svn: 150826

* Revert r150288, "Allow Post-RA LICM to hoist reserved register reads."Jakob Stoklund Olesen2012-02-171-11/+0
| | | | | | | | | | This caused miscompilations on out-of-tree targets, and possibly i386 as well. I'll find some other way of hoisting %rip-relative loads from loops containing calls. llvm-svn: 150816
* Don't lazily allocate eh_frame. We're not lazily allocating things like the ↵David Chisnall2012-02-171-22/+26
| | | | | | | | LSDA, which are only used when the eh frame is used, so this lazy allocation doesn't really make sense. Fix the type of eh_frame on Solaris so that Sun ld doesn't fail to combine them (thus making it impossible for the unwind library to find them and breaking exceptions). llvm-svn: 150814
