* Object: Add isSection{Data,BSS}.Michael J. Spencer2011-09-281-0/+14
| | | | git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@140721 91177308-0d34-0410-b5e6-96231b3b80d8
* Object: make the following changes into SymbolRefBenjamin Kramer2011-09-141-1/+50
| | | | | | | | | | | - 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.

* ObjectFile: Add a method to check whether a section contains a symbol.Benjamin Kramer2011-07-151-0/+8
| | | | | | | - No ELF or COFF implementation yet, I don't have a way to test that. Should be straightforward to add though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135288 91177308-0d34-0410-b5e6-96231b3b80d8

* Assorted bugfixes in object file handling:Eric Christopher2011-04-031-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | - 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.
