2010-02-13Split some code out to a helper function (FindReusablePredBB)Chris Lattner
and add a doxygen comment. Cache the phi entry to avoid doing tons of PHINode::getBasicBlockIndex calls in the common case. On my insane testcase from re2c, this speeds up CGP from 617.4s to 7.9s (78x). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96083 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-13PHINode::getBasicBlockIndex is O(n) in the number of inputsChris Lattner
to a PHI, avoid it in the common case where the BB occurs in the same index for multiple phis. This speeds up CGP on an insane testcase from 8.35 to 3.58s. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96080 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-13Fix PR6283.Jakob Stoklund Olesen
When coalescing with a physreg, remember to add imp-def and imp-kill when dealing with sub-registers. Also fix a related bug in VirtRegRewriter where substitutePhysReg may reallocate the operand list on an instruction and invalidate the reg_iterator. This can happen when a register is mentioned twice on the same instruction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96072 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-13Teach MachineFrameInfo to track maximum alignment while stack objects are beingEvan Cheng
created. This ensures it's updated at all time. It means targets which perform dynamic stack alignment would know whether it is required and whether frame pointer register cannot be made available register allocation. This is a fix for rdar://7625239. Sorry, I can't create a reasonably sized test case. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96069 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-13Enable the inlinehint attribute in the Inliner.Jakob Stoklund Olesen
Functions explicitly marked inline will get an inlining threshold slightly more aggressive than the default for -O3. This means than -O3 builds are mostly unaffected while -Os builds will be a bit bigger and faster. The difference depends entirely on how many 'inline's are sprinkled on the source. In the CINT2006 suite, only these tests are significantly affected under -Os: Size Time 471.omnetpp +1.63% -1.85% 473.astar +4.01% -6.02% 483.xalancbmk +4.60% 0.00% Note that 483.xalancbmk runs too quickly to give useful timing results. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96066 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-12When save/restoring CR at prolog/epilog, in a largeDale Johannesen
stack frame, the prolog/epilog code was using the same register for the copy of CR and the address of the save slot. Oops. This is fixed here for Darwin, sort of, by reserving R2 for this case. A better way would be to do the store before the decrement of SP, which is safe on Darwin due to the red zone. SVR4 probably has the same problem, but I don't know how to fix it; there is no red zone and R2 is already used for something else. I'm going to leave it to someone interested in that target. Better still would be to rewrite the CR-saving code completely; spilling each CR subregister individually is horrible code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96015 91177308-0d34-0410-b5e6-96231b3b80d8
