2010-03-14change EH related stuff (other than EH_LABEL) to use MCSymbolChris Lattner
instead of label ID's. This cleans up and regularizes a bunch of code and makes way for future progress. Unfortunately, this pointed out to me that JITDwarfEmitter.cpp is largely copy and paste from DwarfException/MachineModuleInfo and other places. This is very sad and disturbing. :( One major change here is that TidyLandingPads moved from being called in DwarfException::BeginFunction to being called in DwarfException::EndFunction. There should not be any functionality change from doing this, but I'm not an EH expert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98459 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-13simplify EmitFrameMoves to take BaseLabel in as a symbolChris Lattner
instead of as a stem+idx pair, simplify the "is a new location" check to use symbol comparison. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98432 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-10move three lowering hooks from MAI to TLOF and make one of themChris Lattner
semantic instead of syntactic. This completes MCization of darwin/x86[-64]! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98145 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-10mcize the rest of EH emission, only one more directive missingChris Lattner
for darwin/x86 to be completely mcized. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98130 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-10add some fixme's for MCizing. EH still has a few things thatChris Lattner
need to be MCized, but the last debug info thing are LEB and cygwin specific (which the MC api doesn't support yet) and one specific form of EmitReference which I'll tackle next. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98116 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-09eliminate EOL, adding all comments with the OutStreamer.AddComment Chris Lattner
method. With this, comments should end up on the same lines as the .byte directives (for example) and we now get no output with: $ llc CodeGen/X86/2009-02-12-DebugInfoVLA.ll -o - -filetype=null -asm-verbose woot. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98105 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-09now that the debug and eh emitters use a common .set counter,Chris Lattner
we can eliminate "flavor". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98011 91177308-0d34-0410-b5e6-96231b3b80d8
2010-03-08simplify EmitSectionOffset to always use .set if it isChris Lattner
available, the only thing this affects is that we produce .set in one case we didn't before, which shouldn't harm anything. Make EmitSectionOffset call EmitDifference instead of duplicating it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98005 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-08elimiante the DWLabel class, using MCSymbol instead. Start Chris Lattner
switching some stuff over to passing around MCSymbol* instead of stem+ID. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97993 91177308-0d34-0410-b5e6-96231b3b80d8
2010-02-26A much cleaner (and less code!) way of inserting the correct amount of paddingBill Wendling
for alignment into the LSDA. If the TType base offset is emitted, then put the padding there. Otherwise, put it in the call site table length. There will be no conflict between the two sites when placing the padding in one place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97277 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-26Add another (and hopefully the last) exception case, where once we recalculateBill Wendling
the alignment requirement, if it no longer makes the TType base offset overflow into extra bytes, then we need to pad to those bytes ourselves. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97196 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-25Catch a corner case where adding the padding to the "TType base offset" fieldBill Wendling
will eliminate the need for padding in the "Call site table length". E.g., if we have this: GCC_except_table1: Lexception1: .byte 0xff ## @LPStart Encoding = omit .byte 0x9b ## @TType Encoding = indirect pcrel sdata4 .byte 0x7f ## @TType base offset .byte 0x03 ## Call site Encoding = udata4 .byte 0x89 ## Call site table length with padding of 1. We want to emit the padding like this: GCC_except_table1: Lexception1: .byte 0xff ## @LPStart Encoding = omit .byte 0x9b ## @TType Encoding = indirect pcrel sdata4 .byte 0xff ## @TType base offset .space 1,0 ## Padding .byte 0x03 ## Call site Encoding = udata4 .byte 0x89 ## Call site table length and not with padding on the "Call site table length" entry. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97183 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-24LLVM puts padding bytes in the __gcc_except_tab section after theBill Wendling
GCC_except_table label but before the Lexception, which the FDE references. This causes problems as the FDE does not point to the start of an LSDA chunk. Use an unnormalized uleb128 for the call-site table length that includes the padding. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97078 91177308-0d34-0410-b5e6-96231b3b80d8

2010-02-15It turns out that we emitted completely wrong common EH frame since the ↵Anton Korobeynikov
early beginning! The "z" CIE augmentation mark indicates that there is an extra word containing the size of augmentation section. However, even for frames w/o any augmentation data we emitted size uleb! (this is the case of "unwinding through C code"). Thus frame moves information was emitterd completely wrong. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@96287 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-22add a new DwarfPrinter::EmitEncodingByte method which handlesChris Lattner
