| | | | llvm-svn: 121034
* Add support for binary encoding of ARM 'adr' instructions referencing constantJim Grosbach2010-12-021-1/+6
| | | | | | pool entries (LEApcrel pseudo). Ongoing saga of rdar://8542291. llvm-svn: 120635
* Define generic 1, 2 and 4 byte pc relative relocations. They are commonRafael Espindola2010-11-281-6/+6
| | | | | | and at least the 4 byte one will be needed to implement the .cfi_* directives. llvm-svn: 120240

* On ELF we need to know which symbols are used in relocations to decide ifRafael Espindola2010-10-051-1/+1
| | | | | | | they should be in the symbol table or not. Instead of "guessing", just compute the symbol table after the relocations are known. llvm-svn: 115619
* This adds a Darwin x86_64 relocation encoding for a subtraction expressionKevin Enderby2010-10-021-13/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 115389
* Correctly produce R_X86_64_32 or R_X86_64_32S.Rafael Espindola2010-09-301-0/+2
| | | | | | | | | | | | | 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. llvm-svn: 115134
* Make it possible for the MCObjectWriter to decide if a given fixup is fullyRafael Espindola2010-09-301-0/+118
| | | | | | | | | | | 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. llvm-svn: 115131
