Object, COFF: Infer symbol sizes from adjacent symbols Use the position of the subsequent symbol in the object file to infer the size of it's predecessor.

Add an implementation for llvm-nm’s -print-file-name option (aka -o and -A). The -print-file-name option in llvm-nm is to precede each symbol with the object file it came from. While code for the parsing of this option and its aliases existed there was no code to implement it. llvm-svn: 213906

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

Add the -just-symbol-name (aka -j) flag to llvm-nm to just print the symbol’s name. On darwin the -j flag is used (often in combinations with other flags) to produce a complete list of symbol names which than can then be reorder and used with ld(1)’s -order_file. llvm-svn: 212294

Add the "-s" flag to llvm-nm for Mach-O files that prints symbols only in the specified section. This is same functionality as darwin’s nm(1) "-s" flag. There is one FIXME in the code and I’m all ears to anyone that can help me with that. This option takes exactly two strings and should be allowed anywhere on the command line. Such that "llvm-nm -s __TEXT __text foo.o" would work. But that does not as the CommandLine Library does not have a way to make this work as far as I can tell. For now the "-s __TEXT __text" has to be last on the command line. llvm-svn: 212842

Revert "Fix a nomenclature error in llvm-nm." This reverts commit r205479. It turns out that nm does use addresses, it is just that every reasonable relocatable ELF object has sections with address 0. I have no idea if those exist in reality, but it at least it shows that llvm-nm should use the name address. The added test was includes an unusual .o file with non 0 section addresses. I created it by hacking ELFObjectWriter.cpp. Really sorry for the churn. llvm-svn: 205493

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

Update MachOObjectFile::getSymbolAddress so it returns UnknownAddressOrSize for undefined symbols, so it matches what COFFObjectFile::getSymbolAddress does. This allows llvm-nm to print spaces instead of 0’s for the value of undefined symbols in Mach-O files. To make this change other uses of MachOObjectFile::getSymbolAddress are updated to handle when the Value is returned as UnknownAddressOrSize. Which is needed to keep two of the ExecutionEngine tests working for example. llvm-svn: 209253

Revert "Fix a nomenclature error in llvm-nm." This reverts commit r205479. It turns out that nm does use addresses, it is just that every reasonable relocatable ELF object has sections with address 0. I have no idea if those exist in reality, but it at least it shows that llvm-nm should use the name address. The added test was includes an unusual .o file with non 0 section addresses. I created it by hacking ELFObjectWriter.cpp. Really sorry for the churn. llvm-svn: 205493

Add the -just-symbol-name (aka -j) flag to llvm-nm to just print the symbol’s name. On darwin the -j flag is used (often in combinations with other flags) to produce a complete list of symbol names which than can then be reorder and used with ld(1)’s -order_file. llvm-svn: 212294

Add the "-s" flag to llvm-nm for Mach-O files that prints symbols only in the specified section. This is same functionality as darwin’s nm(1) "-s" flag. There is one FIXME in the code and I’m all ears to anyone that can help me with that. This option takes exactly two strings and should be allowed anywhere on the command line. Such that "llvm-nm -s __TEXT __text foo.o" would work. But that does not as the CommandLine Library does not have a way to make this work as far as I can tell. For now the "-s __TEXT __text" has to be last on the command line. llvm-svn: 212842

Add an implementation for llvm-nm’s -print-file-name option (aka -o and -A). The -print-file-name option in llvm-nm is to precede each symbol with the object file it came from. While code for the parsing of this option and its aliases existed there was no code to implement it. llvm-svn: 213906

Test that nm uses addresses even with ELF .o files.
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
