2010-10-05On ELF we need to know which symbols are used in relocations to decide ifRafael Espindola
they should be in the symbol table or not. Instead of "guessing", just compute the symbol table after the relocations are known. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115619 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-02This adds a Darwin x86_64 relocation encoding for a subtraction expressionKevin Enderby
where both symbols are "local", that is non-external symbols, and there is no "base" for the symbols used in the expression, that is the section has no non-temporary symbols. This case looks like this: % cat local_reloc_A-B.s .long 0 LB: .long 1 .long LA - LB - 4 .long 2 LA: .long 3 which llvm-mc will not encode without this patch, generates a "unsupported local relocations in difference" error, but the Darwin assembler will encode with relocation entries like this: % otool -rv a.out l.out a.out: Relocation information (__TEXT,__text) 2 entries address pcrel length extern type scattered symbolnum/value 00000008 False long False SUB False 1 (__TEXT,__text) 00000008 False long False UNSIGND False 1 (__TEXT,__text) which is very similar to what is encoded when the symbols don't have the leading 'L' and they are not temporary symbols. Which llvm-mc and the Darwin assembler will encoded like this: Relocation information (__TEXT,__text) 2 entries address pcrel length extern type scattered symbolnum/value 00000008 False long True SUB False B 00000008 False long True UNSIGND False A This is the missing relocation encoding needed to allow the Mach-O x86 Dwarf file and line table to be emitted. So this patch also removes the TODO from the if() statement in MCMachOStreamer::Finish() that didn't call MCDwarfFileTable::Emit() for 64-bit targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115389 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-30Correctly produce R_X86_64_32 or R_X86_64_32S.Rafael Espindola
With this patch in movq $foo, foo(%rip) foo: .long foo We produce a R_X86_64_32S for the first relocation and R_X86_64_32 for the second one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115134 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-30Make it possible for the MCObjectWriter to decide if a given fixup is fullyRafael Espindola
resolved or not. Different object files have different restrictions and different native assemblers have different idiosyncrasies we want to emulate for now. Move the existing MachO logic to the new place and implement an ELF one that gets fixups to globals right. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@115131 91177308-0d34-0410-b5e6-96231b3b80d8

2010-03-19MC/Mach-O/x86_64: Add relocation support.Daniel Dunbar
- This is "extraordinarily" Darwin 'as' compatible. See the litany of FIXMEs littered about for more information. - There are a few cases which seem to clearly be 'as' bugs which I have left unsupported, and there is one cases where we diverge but should fix if it blocks diffing .o files (Darwin 'as' ends up widening a jump unnecessarily). - 403.gcc build, runs, and diffs equivalently to the 'as' built version now (using llvm-mc). However, it builds so slowly that I wouldn't recommend trying it quite yet. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98974 91177308-0d34-0410-b5e6-96231b3b80d8
