* Avoid a gcc warning.Rafael Espindola2011-05-101-1/+2
| | | | llvm-svn: 131161
* On MachO, unlike ELF, there should be no relocation to produce the CIE pointer.Rafael Espindola2011-05-101-8/+17
| | | | llvm-svn: 131149
* The EH symbols are only needed in eh_frame, not debug_frame.Rafael Espindola2011-05-101-2/+2
| | | | llvm-svn: 131146

| | | | llvm-svn: 131031
* MCDwarf: Don't save Twine to local variable, this is almost never safe to doDaniel Dunbar2011-05-031-2/+2
| | | | | | | (and should thus never be done). - Should fix a crash on win32. llvm-svn: 130793
* GCC uses a different encoding of pointers in the FDE when usingRafael Espindola2011-05-011-8/+12
| | | | | | -fno-dwarf2-cfi-asm. Implement the same behavior. llvm-svn: 130637
* Simplify the handling of pcrel relocations on ELF. Now we do the right thingRafael Espindola2011-05-011-11/+6
| | | | | | | | | | for all symbol differences and can drop the old EmitPCRelSymbolValue method. This also make getExprForFDESymbol on ELF equal to the one on MachO, and it can be made non-virtual. llvm-svn: 130634
* Avoid some uses of .uleb128. This is a small speedup and more importantlyRafael Espindola2011-04-291-17/+22
| | | | | | | lets this code be used when producing assembly code for old assemblers without uleb support. llvm-svn: 130544
* Last bit by bit compatibility patch to MCDwarf.cpp: If a FDE with no LSDA isRafael Espindola2011-04-291-5/+20
| | | | | | assigned to a CIE that requires one, just output a 0. llvm-svn: 130472

| | | | | | in the same order as the one in CodeGen. llvm-svn: 130471
* Add the getExprForFDESymbol method that responsible for computing theRafael Espindola2011-04-281-12/+9
| | | | | | expressions used in the FDE to refer to symbols. llvm-svn: 130437
* Add a getExprForPersonalitySymbol method to MCAsmInfo. Use it whenRafael Espindola2011-04-281-1/+14
| | | | | | converting the symbol passed to .cfi_personality into bytes is the file. llvm-svn: 130400
* Mark the EH symbol global or weak if the corresponding function is.Rafael Espindola2011-04-281-0/+1
| | | | llvm-svn: 130397
* Add a small temporary hack for producing identical eh_frame sections on OS X.Rafael Espindola2011-04-281-5/+12
| | | | | | | This removes one of the main advantages of moving eh_frame to MC, but makes the transition a lot easier to debug (run md5). llvm-svn: 130379
* Produce the EH_frame# symbols if needed.Rafael Espindola2011-04-281-2/+11

* Delete the other unused variable in this function. Sorry I missed thisChandler Carruth2011-04-221-1/+0
| | | | | | the first time through. llvm-svn: 129969
* Remove an unused variable from a function. This is a likely cut-paste-o.Chandler Carruth2011-04-221-1/+0
| | | | | | | | Silences GCC warning. I wonder why Clang doesn't warn on this... llvm-svn: 129968
* Compute the size of the FDE encoding instead of hard coding it. UpdateRafael Espindola2011-04-221-15/+20
| | | | | | X8664_ELFTargetObjectFile::getFDEEncoding to match reality. llvm-svn: 129959

* Implement .cfi_same_value.Rafael Espindola2011-04-121-0/+6
| | | | llvm-svn: 129361
* Rename TargetFrameInfo into TargetFrameLowering. Also, put couple of FIXMEs ↵Anton Korobeynikov2011-01-101-1/+1

| | | | llvm-svn: 122615
* Implement cfi_def_cfa. Also don't convert to dwarf reg numbers twice. LooksRafael Espindola2010-12-291-14/+25
| | | | | | like 6 is a fixed point of that and so the previous tests were OK :-) llvm-svn: 122614
* Don't produce a "DW_CFA_advance_loc 0".Rafael Espindola2010-12-281-1/+2
