* change EH related stuff (other than EH_LABEL) to use MCSymbolChris Lattner2010-03-141-44/+33
| | | | | | | | | | | | | | | | | | 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

* A much cleaner (and less code!) way of inserting the correct amount of paddingBill Wendling2010-02-261-50/+6

* Catch a corner case where adding the padding to the "TType base offset" fieldBill Wendling2010-02-251-2/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | 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.

| | | | | | early beginning! The "z" CIE augmentation mark indicates that there is an extra word containing the size of augmentation section.
