2011-01-10Rename TargetFrameInfo into TargetFrameLowering. Also, put couple of FIXMEs ↵Anton Korobeynikov

2010-12-10Teach isCSRestore() that ARM/Thumb2 functions will use post-modify LDRJim Grosbach
instructions to restore a single register rather than an LDM instruction. rdar://8754999 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121498 91177308-0d34-0410-b5e6-96231b3b80d8
2010-12-09ARM stm/ldm instructions require more than one register in the register list.Jim Grosbach
Otherwise, a plain str/ldr should be used instead. Make sure we account for that in prologue/epilogue code generation. rdar://8745460 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121391 91177308-0d34-0410-b5e6-96231b3b80d8

vpush instructions to save / restore VFP / NEON registers like this: vpush {d8,d10,d11} vpop {d8,d10,d11} vpush and vpop do not allow gaps in the register list. rdar://8728956 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@121197 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-30Enable sibling call optimization of libcalls which are expanded duringEvan Cheng
legalization time. Since at legalization time there is no mapping from SDNode back to the corresponding LLVM instruction and the return SDNode is target specific, this requires a target hook to check for eligibility. Only x86 and ARM support this form of sibcall optimization right now. rdar://8707777 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120501 91177308-0d34-0410-b5e6-96231b3b80d8

2010-11-22Fix epilogue codegen to avoid leaving the stack pointer in an invalidEvan Cheng
state. Previously Thumb2 would restore sp from fp like this: mov sp, r7 sub, sp, #4 If an interrupt is taken after the 'mov' but before the 'sub', callee-saved registers might be clobbered by the interrupt handler. Instead, try restoring directly from sp: add sp, #4 Or, if necessary (with VLA, etc.) use a scratch register to compute sp and then restore it: sub.w r4, r7, #8 mov sp, r7 rdar://8465407 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119977 91177308-0d34-0410-b5e6-96231b3b80d8
