emscripten-fastcomp/test/CodeGen/X86/tailcall-largecode.ll, branch 1.13.2 LLVM with the emscripten fastcomp javascript backend https://git.amat.us/emscripten-fastcomp/atom/test/CodeGen/X86/tailcall-largecode.ll?h=1.13.2 2012-07-04T19:28:31Z Ensure CopyToReg nodes are always glued to the call instruction. 2012-07-04T19:28:31Z Jakob Stoklund Olesen stoklund@2pi.dk 2012-07-04T19:28:31Z urn:sha1:b8720787015dc73d8a050b063366be6c3ad01946 The CopyToReg nodes that set up the argument registers before a call must be glued to the call instruction. Otherwise, the scheduler may emit the physreg copies long before the call, causing long live ranges for the fixed registers. Besides disabling good register allocation, that can also expose problems when EmitInstrWithCustomInserter() splits a basic block during the live range of a physreg. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@159721 91177308-0d34-0410-b5e6-96231b3b80d8 Use pushq / popq instead of subq $8, %rsp / addq $8, %rsp to adjust stack in 2011-01-03T22:53:22Z Evan Cheng evan.cheng@apple.com 2011-01-03T22:53:22Z urn:sha1:7158e08b8e619f4dcac9834c57f5f8afd6eea2eb prologue and epilogue if the adjustment is 8. Similarly, use pushl / popl if the adjustment is 4 in 32-bit mode. In the epilogue, takes care to pop to a caller-saved register that's not live at the exit (either return or tailcall instruction). rdar://8771137 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@122783 91177308-0d34-0410-b5e6-96231b3b80d8 Do not force indirect tailcall through fixed registers: eax, r11. Add support to allow loads to be folded to tail call instructions. 2010-03-14T03:48:46Z Evan Cheng evan.cheng@apple.com 2010-03-14T03:48:46Z urn:sha1:f48ef0365545b6160836e3f4b4a210d1e21f1881 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98465 91177308-0d34-0410-b5e6-96231b3b80d8 Fix http://llvm.org/PR5729: x86-64 tail calls were putting their targets into 2010-01-09T18:56:43Z Jeffrey Yasskin jyasskin@google.com 2010-01-09T18:56:43Z urn:sha1:a77169dbeb250d1992938650084dc799472fb956 R11, and then asserting that the target was in R9. Since R9 isn't reserved for the target anymore, and is used as an argument, this patch changes the assertion. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@93065 91177308-0d34-0410-b5e6-96231b3b80d8
