[Object] Add {begin,end}_dynamic_symbols stubs and implementation for ELF. Add -D option to llvm-nm to dump dynamic symbols. Patch by David Meyer. llvm-svn: 151600
2012-02-28 08:40:37 +08:00
RUN: llvm-nm -D %p/Inputs/shared-object-test.elf-i386 \
Fix SymbolRef::getAddress implementation for ELF. The 'value' field in symbol table entry should be treated differently for relocatable and relocated files. This patch fixes symbol addresses printed by llvm-nm for executables and shared objects. llvm-svn: 164365

Mark the first dynamic elf symbol as SF_FormatSpecific. llvm-svn: 200578

ELF-32-NOT: U
Fix llvm-nm to print the full 64-bit address for symbols in 64-bit object files. The implementation might be better to have a method is64Bit() in the class SymbolicFile instead of having the static routine isSymbolList64Bit() in llvm-nm.cpp . But this is very much in the sprit of isObject() and getNMTypeChar() in llvm-nm.cpp that has a series of if else statements based on the specific class of the SymbolicFile. I can update this if folks would like. Also the tests were updated to be explicit about checking the address for 64-bits or 32-bits from object files. llvm-svn: 208463

Only ELF has a dynamic symbol table. Remove it from ObjectFile. COFF has only one symbol table. MachO has a LC_DYSYMTAB, but that is not a symbol table, just extra info about the one symbol table (LC_SYMTAB). IR (coming soon) also has only one table. llvm-svn: 200488
