Rui Ueyama 82ebd8e36d readobj: Dump PE/COFF optional records. 
These records are mandatory for executables and are used by the loader.

Reviewers: rafael

CC: llvm-commits

Rafael Espindola 806f006490 Handle relocations that don't point to symbols. 
In ELF (as in MachO), not all relocations point to symbols. Represent this
properly by using a symbol_iterator instead of a SymbolRef. Update llvm-readobj
ELF's dumper to handle relocatios without symbols.

Rafael Espindola 0d15f7313f Change getRelocationAdditionalInfo to be ELF only. 
It was only implemented for ELF where it collected the Addend, so this
patch also renames it to getRelocationAddend.

Rafael Espindola 1e48387962 Clarify getRelocationAddress x getRelocationOffset a bit. 
getRelocationAddress is for dynamic libraries and executables,
getRelocationOffset for relocatable objects.

Mark the getRelocationAddress of COFF and MachO as not implemented yet. Add a
test of ELF's. llvm-readobj -r now prints the same values as readelf -r.

Guy Benyei 83c74e9fad Add static cast to unsigned char whenever a character classification function is called with a signed char argument, in order to avoid assertions in Windows Debug configuration.

Currently only implemented for ELF.

llvm-svn: 165588
 2012-10-10 01:45:52 +00:00
Andrew Kaylor 3f31fa05d5 This patch adds new functions to the SectionRef and ObjectFile interfaces to determine whether or not a section is meant to be read-only. These functions will be used by the MCJIT RuntimeDyld to give hints to the memory manager during the object loading process in a future patch.

Preston Gurd 2138ef6d3d This patch improves the MCJIT runtime dynamic loader by adding new handling 
of zero-initialized sections, virtual sections and common symbols
and preventing the loading of sections which are not required for
execution such as debug information.

David Meyer 2fc34c5f84 [Object] 
* Add begin_dynamic_table() / end_dynamic_table() private interface to ELFObjectFile.
* Add begin_libraries_needed() / end_libraries_needed() interface to ObjectFile, for grabbing the list of needed libraries for a shared object or dynamic executable.
* Implement this new interface completely for ELF, leave stubs for COFF and MachO.
* Add 'llvm-readobj' tool for dumping ObjectFile information.

David Meyer 7e4b976c36 [Object] Add symbol attribute flags: ST_ThreadLocal, ST_Common, and ST_Undefined. Implement these completely for ELF. 
Rename ST_External to ST_Unknown, and slightly change its semantics. It now only indicates that the symbol's type
is unknown, not that the symbol is undefined. (For that, use ST_Undefined).

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.
