Michael J. Spencer 9aaa852336 Object/Archive: Add BSD style long file name support and skip internal members. 
llvm-svn: 142981
 2011-10-25 22:30:42 +00:00
Owen Anderson 377137e2ed Remove extraneous printing of "-PC". 
llvm-svn: 142970
 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.

llvm-svn: 142961
 2011-10-25 20:35:53 +00:00
Owen Anderson 52cd8acafc Teach the MachO relocation pretty-printer to interpret ARM half-relocations. 
llvm-svn: 142938
 2011-10-25 18:48:41 +00:00
Owen Anderson 171f485f15 More fixes and improvements to MachO relocation pretty-printing, particular for x86 and x86_64 relocations with addends. 
llvm-svn: 142875
 2011-10-24 23:20:07 +00:00
Owen Anderson c8c94da8c8 Get relocation parsing/dumping to a mostly-working state for MachO files. 
llvm-svn: 142852
 2011-10-24 21:44:00 +00:00
Owen Anderson 953af053eb Stub out some of the MachO relocation decoding hooks. 
llvm-svn: 142840
 2011-10-24 20:19:18 +00:00
Owen Anderson 500ebeb87f Use LLVMBool for a function that logically returns a boolean value. 
llvm-svn: 142683
 2011-10-21 20:35:58 +00:00
Owen Anderson cef5641982 STABS symbols are debug symbols. 
llvm-svn: 142673
 2011-10-21 19:26:54 +00:00
Owen Anderson 07bfdbb233 Bind libObject API for obtaining the section containing a Symbol. 
llvm-svn: 142667
 2011-10-21 18:21:22 +00:00
Owen Anderson f239db40d5 Expand the coverage of the libObject C bindings to include more SectionRef accessors as well as Symbol iterators. 
llvm-svn: 142661
 2011-10-21 17:50:59 +00:00
Michael J. Spencer 443410d722 Object/COFF: Remove useless test. 
llvm-svn: 142408
 2011-10-18 19:51:36 +00:00
Michael J. Spencer 097be9f63c Object/COFF: Change type from a struct to a uint16_t. The struct would be 
incorrect for bigendian systems.

llvm-svn: 142403
 2011-10-18 19:31:59 +00:00
Michael J. Spencer 1d19f97ea5 Object: Add some types to SymbolRef::Type. 
Some of these can be true at the same time and there are a lot to add,
so this should be turned into a bitfield. Some of the other accessors
should probably be folded into this.

llvm-svn: 142318
 2011-10-17 23:55:06 +00:00
Michael J. Spencer 321731539e Object: Add isSymbolAbsolute and getSymbolSection. 
llvm-svn: 142317
 2011-10-17 23:54:46 +00:00
Michael J. Spencer 017597540e Object: Add isSymbolWeak. 
llvm-svn: 142316
 2011-10-17 23:54:22 +00:00
Michael J. Spencer 89a7a5ea1f Object/COFF: Expose more data in the public API. 
llvm-svn: 142315
 2011-10-17 23:53:56 +00:00
Michael J. Spencer 4f91c2f2bd Object: Implement casting for concrete classes. 
llvm-svn: 142314
 2011-10-17 23:53:37 +00:00
Michael J. Spencer d39466760a Object: Fix redundant name. 
llvm-svn: 142238
 2011-10-17 20:19:29 +00:00
Michael J. Spencer 834bd602e6 ELF: Fix the section that relocations apply to. Add test to verify. Patch by Danil Malyshev! 
llvm-svn: 141901
 2011-10-13 22:30:10 +00:00
Michael J. Spencer 9a28851e52 COFF: Implement sectionContainsSymbol for relocatable files only. 
llvm-svn: 141884
 2011-10-13 20:36:54 +00:00
Nick Lewycky d3043965b9 Elf_Word is not POD! Stop using it in a DenseMap. 
llvm-svn: 141851
 2011-10-13 03:30:21 +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
NAKAMURA Takumi 9bfcf77638 lib/Object/ELFObjectFile.cpp: Fix undefined behavior for MC/ELF/many-section.s not to fail (on msvc). 
DenseMap::lookup(k) would return "default constructor value" when k was not met. It would be useless when value type were POD.

llvm-svn: 141774
 2011-10-12 10:28:55 +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. 
llvm-svn: 141684
 2011-10-11 17:32:27 +00:00
Nick Lewycky 43f01cae95 Reapply r141605 with fixes for appropriate handling of reserved section numbers 
in st_shndx fields.

llvm-svn: 141639
 2011-10-11 03:18:58 +00:00
Nick Lewycky 7adc4370e0 Add support for .symtab_shnidx. Unfortunately, doing this required breaking a 
layer of abstraction around SymbolRef where you can read its private
SymbolPimpl member.

llvm-svn: 141636
 2011-10-11 02:57:48 +00:00
Nick Lewycky 35a90c4baf Revert r141605 as it broke tests for llvm-nm. 
llvm-svn: 141614
 2011-10-11 00:38:56 +00:00
Nick Lewycky fdbb7c51e9 Add support for reading many-section ELF files. 
If you want to tackle adding the testcase, let me know. It's a 4.2MB ELF file
and I'll be happy to mail it to you.

Michael J. Spencer d3b7b12618 Object: Add archive support. 
llvm-svn: 140626
 2011-09-27 19:36:55 +00:00
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.
