Owen Anderson 04e46b6ae4 Include the full 64 bits of relocation data in the type info for MachO relocations, so that we can recognize scattered relocations. 
llvm-svn: 143033
 2011-10-26 17:10:22 +00:00
Owen Anderson 7be76590e6 Expand relocation type field to 64 bits. MachO scattered relocations require 33 bits of type info.

Owen Anderson b92de2de71 Improve pretty printing of GOT relocations in MachO on x86_64.

 2011-10-25 20:44:00 +00:00
Owen Anderson fa3e5200b8 Add support for the notion of "hidden" relocations. On MachO, these are relocation entries that are used as additional information for other, real relocations, rather than being relocations themselves. 
I'm not familiar enough with ELF or COFF to know if they should have any relocations marked hidden.

Owen Anderson 52cd8acafc Teach the MachO relocation pretty-printer to interpret ARM half-relocations.

 2011-10-17 20:19:29 +00:00
Owen Anderson 000721f058 The VMAs stored in the symbol table of a MachO file are absolute addresses, not offsets from the section. 
llvm-svn: 141828
 2011-10-12 22:37:10 +00:00
Owen Anderson 34e1707fbb Don't label a STAB debugging symbol as a function symbol. 
llvm-svn: 141824
 2011-10-12 22:23:12 +00:00
Owen Anderson fb02ecde5e sectionContainsSymbol needs to be based on VMA's rather than section indices to properly account for files with segment load commands that contain no sections. 
llvm-svn: 141822
 2011-10-12 22:21:32 +00:00
Owen Anderson f903c154c7 Section indices in MachO symbol tables begin at 1, not 0. 
llvm-svn: 141815
 2011-10-12 21:43:24 +00:00
Owen Anderson 27c579dba4 Expose MachOObjectFile externally, like we do for COFF. First step in reducing the amount of special-purpose code needed for llvm-objdump.

Michael J. Spencer 800619f2bb Object: Add isSection{Data,BSS}. 
llvm-svn: 140721

Benjamin Kramer 75d1cf3391 Object: make the following changes into SymbolRef 
- Add enum SymbolType and function getSymbolType()
- Add function isGlobal() - it's returns true for symbols that can be used in another objects, such as library functions.
- Rename function getAddress() to getOffset() and add new function getAddress(), because currently getAddress() returns section offset of symbol first byte. new getAddress() return symbol address.
- Change usage SymbolRef::getAddress() to getOffset() in tools/llvm-nm and tools/llvm-objdump.

Benjamin Kramer f6f3e81c07 ObjectFile: Add a method to check whether a section contains a symbol. 
- No ELF or COFF implementation yet, I don't have a way to test that.
  Should be straightforward to add though.
