* Enable the inlinehint attribute in the Inliner.Jakob Stoklund Olesen2010-02-131-13/+12
| | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 96066

* rip out the 'heinous' x86 MCCodeEmitter implementation.Chris Lattner2010-02-135-340/+4
| | | | | | | We still have the templated X86 JIT emitter, *and* the almost-copy in X86InstrInfo for getting instruction sizes. llvm-svn: 96059

* Besides removing phi cycles that reduce to a single value, also remove deadBob Wilson2010-02-136-25/+114
| | | | | | | | phi cycles. Adjust a few tests to keep dead instructions from being optimized away. This (together with my previous change for phi cycles) fixes Apple radar 7627077. llvm-svn: 96057
* Override dominates and properlyDominates for SCEVAddRecExpr, as aDan Gohman2010-02-132-0/+19
| | | | | | | SCEVAddRecExpr doesn't necessarily dominate blocks merely dominated by all of its operands. This fixes an abort compiling 403.gcc. llvm-svn: 96056

| | | | | | | | | | | | whose opcodes extend into the ModR/M field using the Form field of the instruction rather than by special casing each instruction. Commented out the special casing of VMCALL, which is the first instruction to use this special form. While I was in the neighborhood, added a few comments for people modifying the Intel disassembler. llvm-svn: 96043

* When save/restoring CR at prolog/epilog, in a largeDale Johannesen2010-02-122-14/+60
| | | | | | | | | | | | | | | | | 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. llvm-svn: 96015
