2009-10-27Fix a pretty serious misfeature of the inliner: if it inlines a functionChris Lattner
with multiple return values it inserts a PHI to merge them all together. However, if the return values are all the same, it ends up with a pointless PHI and this pointless PHI happens to really block SRoA from happening in at least a silly C++ example written by Doug, but probably others. This fixes rdar://7339069. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85206 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-27Change Thumb1 and Thumb2 instructions to separate opcode from operands with ↵Evan Cheng

2009-10-27Automatically do the equivalent of freeMachineCodeForFunction(F) when F isJeffrey Yasskin
being destroyed. This allows users to run global optimizations like globaldce even after some functions have been jitted. This patch also removes the Function* parameter to JITEventListener::NotifyFreeingMachineCode() since it can cause that to be called when the Function is partially destroyed. This change will be even more helpful later when I think we'll want to allow machine code to actually outlive its Function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85182 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-26Allow the aggressive anti-dep breaker to process the same region multiple ↵David Goodwin

2009-10-26Check in the experimental GEP splitter pass. This pass splits complexDan Gohman
GEPs (more than one non-zero index) into simple GEPs (at most one non-zero index). In some simple experiments using this it's not uncommon to see 3% overall code size wins, because it exposes redundancies that can be eliminated, however it's tricky to use because instcombine aggressively undoes the work that this pass does. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85144 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-26When checking whether a def of an aliased register is dead, ask theDan Gohman
machineinstr whether the aliased register is dead, rather than the original register is dead. This allows it to get the correct answer when examining an instruction like this: CALLpcrel32 <ga:foo>, %AL<imp-def>, %EAX<imp-def,dead> where EAX is dead but a subregister of it is still live. This fixes PR5294. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85135 91177308-0d34-0410-b5e6-96231b3b80d8

2009-10-26Make LSR's OptimizeShadowIV ignore induction variables with negativeDan Gohman
strides for now, because it doesn't handle them correctly. This fixes a miscompile of SingleSource/Benchmarks/Misc-C++/ray. This problem was usually hidden because indvars transforms such induction variables into negations of canonical induction variables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85118 91177308-0d34-0410-b5e6-96231b3b80d8
2009-10-26- Revert some changes from 85044, 85045, and 85047 that broke x86_64 tests andEvan Cheng
bootstrapping. It's not safe to leave identity subreg_to_reg and insert_subreg around. - Relax register scavenging to allow use of partially "not-live" registers. It's common for targets to operate on registers where the top bits are undef. e.g. s0 = d0 = insert_subreg d0<undef>, s0, 1 ... = d0 When the insert_subreg is eliminated by the coalescer, the scavenger used to complain. The previous fix was to keep to insert_subreg around. But that's brittle and it's overly conservative when we want to use the scavenger to allocate registers. It's actually legal and desirable for other instructions to use the "undef" part of d0. e.g. s0 = d0 = insert_subreg d0<undef>, s0, 1 ... s1 = = s1 = d0 We probably need add a "partial-undef" marker on machine operand so the machine verifier would not complain. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@85091 91177308-0d34-0410-b5e6-96231b3b80d8
