Lang Hames 2ed3bf9527 [lld][MachO] Make sure LC_RPATH command size is a multiple of the pointer size. 
llvm-svn: 251637
 2015-10-29 16:50:26 +00:00
Lang Hames ac416d42fc [lld][MachO] Use a std::string rather than a StringRef for the section name in 
MachODefinedCustomSectionAtom.

The section names for these atoms are initialized from temporaries (e.g.
segName + "/" + sectName), so we can't use StringRef here.

Simon Atanasyan 069b2dd66c [Driver] Ignore -G option in both new and old ELF linker 
This is optimization option that make sense for MIPS targets. We can
safely ignore it now.

llvm-svn: 251519
 2015-10-28 14:50:58 +00:00
Simon Atanasyan 07fe7a943f [Driver] Accept both -m <emulation> and -m<emulation> 
GNU linkers accept both variants and at least for MIPS target gcc passes
joined variant of the '-m' option.

llvm-svn: 248736
 2015-09-28 20:52:21 +00:00
Lang Hames 5c692009bc [lld][MachO] Initial implementation of -flat_namespace and -undefined. 
This is a basic initial implementation of the -flat_namespace and
-undefined options for LLD-darwin. It ignores several subtlties,
but the result is close enough that we can now link LLVM (but not
clang) on Darwin and pass all regression tests.

Rafael Espindola b835ae8e4a Port the error functions from ELF to COFF. 
This has a few advantages

* Less C++ code (about 300 lines less).
* Less machine code (about 14 KB of text on a linux x86_64 build).
* It is more debugger friendly. Just set a breakpoint on the exit function and
  you get the complete lld stack trace of when the error was found.
* It is a more robust API. The errors are handled early and we don't get a
  std::error_code hot potato being passed around.
* In most cases the error function in a better position to print diagnostics
  (it has more context).
