2009-11-17Enable -split-phi-edges by default, except when -regalloc=local.Jakob Stoklund Olesen
The local register allocator doesn't like it when LiveVariables is run. We should also disable edge splitting under -O0, but that has to wait a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89125 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-17Remove a special case for tail merging that seems to be both broken andBob Wilson
unnecessary. It is broken because the "isIdenticalTo" check should be negated. If that is fixed, this code causes the CodeGen/X86/tail-opts.ll test to fail, in the dont_merge_oddly function. And, I confirmed that the regression is real -- the generated code is worse. As far as I can tell, that tail-opts.ll test is checking for what this code is supposed to handle and we're doing the right thing anyway. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@89121 91177308-0d34-0410-b5e6-96231b3b80d8

2009-11-16Revert the test from r88984. It relies on being able to mmap 16GB ofJeffrey Yasskin

2009-11-16Make X86-64 in the Large model always emit 64-bit calls.Jeffrey Yasskin
The large code model is documented at http://www.x86-64.org/documentation/abi.pdf and says that calls should assume their target doesn't live within the 32-bit pc-relative offset that fits in the call instruction. To do this, we turn off the global-address->target-global-address conversion in X86TargetLowering::LowerCall(). The first attempt at this broke the lazy JIT because it can separate the movabs(imm->reg) from the actual call instruction. The lazy JIT receives the address of the movabs as a relocation and needs to record the return address from the call; and then when that call happens, it needs to patch the movabs with the newly-compiled target. We could thread the call instruction into the relocation and record the movabs<->call mapping explicitly, but that seems to require at least as much new complication in the code generator as this change. To fix this, we make lazy functions _always_ go through a call stub. You'd think we'd only have to force lazy calls through a stub on difficult platforms, but that turns out to break indirect calls through a function pointer. The right fix for that is to distinguish between calls and address-of operations on uncompiled functions, but that's complex enough to leave for someone else to do. Another attempt at this defined a new CALL64i pseudo-instruction, which expanded to a 2-instruction sequence in the assembly output and was special-cased in the X86CodeEmitter's emitInstruction() function. That broke indirect calls in the same way as above. This patch also removes a hack forcing Darwin to the small code model. Without far-call-stubs, the small code model requires things of the JITMemoryManager that the DefaultJITMemoryManager can't provide. Thanks to echristo for lots of testing! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@88984 91177308-0d34-0410-b5e6-96231b3b80d8
