* Basic runtime dynamic loading capabilities added to ELFObjectFile, implementedEli Bendersky2012-01-221-19/+239
| | | | | | | | | | | | | in a subclass named DyldELFObject. This class supports rebasing the object file it represents by re-mapping section addresses to the actual memory addresses the object was placed in. This is required for MC-JIT implementation on ELF with debugging support. Patch reviewed on llvm-commits. Developed together with Ashok Thirumurthi and Andrew Kaylor. llvm-svn: 148653
* Fixed ObjectFile functions:Danil Malyshev2011-11-291-13/+36
| | | | | | | | | | | - getSymbolOffset() renamed as getSymbolFileOffset() - getSymbolFileOffset(), getSymbolAddress(), getRelocationAddress() returns same result for ELFObjectFile, MachOObjectFile and COFFObjectFile. - added getRelocationOffset() - fixed MachOObjectFile::getSymbolSize() - fixed MachOObjectFile::getSymbolSection() - fixed MachOObjectFile::getSymbolOffset() for symbols without section data. llvm-svn: 145408

* Object: make the following changes into SymbolRefBenjamin Kramer2011-09-141-1/+78
| | | | | | | | | | | - 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.

* Assorted bugfixes in object file handling:Eric Christopher2011-04-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | - Adds support for sniffing PE/COFF files on win32 (.exe and .dll) which are COFF files that have an MS-DOS compatibility stub on the front of them. - Fixes a bug in the COFFObjectFile's support for the Microsoft COFF extension for long symbol names, wherein it was attempting to parse the leading '/' in an extended symbol name reference as part of the integer offset. - Fixes bugs in COFFObjectFile and ELFObjectFile wherein section and symbol iterators were being returned with uninitialized bytes; the type DataRefImpl is a union between 2 32-bit words (d.a and d.b) and a single intptr_t word (p). Only p was being initialized, so in 32-bit builds the result would be iterators with random upper 32-bit words in their DataRefImpls. This caused random failures when seeking around in object files.
