2013-04-19Use an enum instead of magic constants to improve readability.Bill Wendling
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179820 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-21Move the eliminateCallFramePseudoInstr method from TargetRegisterInfoEli Bendersky
to TargetFrameLowering, where it belongs. Incidentally, this allows us to delete some duplicated (and slightly different!) code in TRI. There are potentially other layering problems that can be cleaned up as a result, or in a similar manner. The refactoring was OK'd by Anton Korobeynikov on llvmdev. Note: this touches the target interfaces, so out-of-tree targets may be affected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175788 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-01X86: Use StackRegister instead of FrameRegister in getFrameIndexReference ↵Alexey Samsonov

MSP430, PPC, PTX, Sparc, X86, XCore. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150878 91177308-0d34-0410-b5e6-96231b3b80d8
2011-08-30Emit segmented-stack specific code into function prologues forRafael Espindola
X86. Modify the pass added in the previous patch to call this new code. This new prologues generated will call a libgcc routine (__morestack) to allocate more stack space from the heap when required Patch by Sanjoy Das. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@138812 91177308-0d34-0410-b5e6-96231b3b80d8
2011-07-25After we've modified the prolog to save volatile registers, generate the compactBill Wendling
unwind encoding for that function. This simply crawls through the prolog looking for machine instrs marked as "frame setup". It can calculate from these what the compact unwind should look like. This is currently disabled because of needed linker support. But initial tests look good. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135922 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-18Move getInitialFrameState from TargetFrameInfo to MCAsmInfo (suggestions forEvan Cheng
better location welcome). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135438 91177308-0d34-0410-b5e6-96231b3b80d8
