Simon Atanasyan d8cadd6f17 [ELF] Customize a relocation table output format (rel / rela). 
Add new virtual virtual function `isRelaOutputFormat` to the
`ELFLinkingContext` class. Call this function everywhere we need to
select a relocation table format.

Rui Ueyama f98a18acb7 [PECOFF] Refactor module-defintion file parser.

 2014-01-11 01:11:49 +00:00
Nick Kledzik 6edd722a2c [mach-o] enable mach-o and native yaml to be intermixed 
The main goal of this patch is to allow "mach-o encoded as yaml" and "native
encoded as yaml" documents to be intermixed.  They are distinguished via 
yaml tags at the start of the document.  This will enable all mach-o test cases
to be written using yaml instead of checking in object files.

The Registry was extend to allow yaml tag handlers to be registered.  The
mach-o Reader adds a yaml tag handler for the tag "!mach-o". 

Additionally, this patch fixes some buffer ownership issues.  When parsing
mach-o binaries, the mach-o atoms can have pointers back into the memory 
mapped .o file.  But with yaml encoded mach-o, name and content are ephemeral, 
so a copyRefs parameter was added to cause the mach-o atoms to make their
own copy.

Rui Ueyama 8b14d14209 [PECOFF] Support module-definition file. 
Module-definition (.def) files are the file containing linker directives,
such as export symbols. Because link.exe supports the same features as command
line options, just as some Linker Script commands overlaps with command line
options, use of module-definition file is not really necessary. It provides
an alternative way to specify some linker options.

This patch implements EXPORTS directive. Other directives will be implemented
in the future.

Rui Ueyama ffd810525d [PECOFF] Warn only when /export options are not compatible. 
Currently LLD always print a warning message if the same symbol is specified
more than once for /export option. It's a bit annoying because specifying the
same symbol with compatible options is actually safe and considered as a
normal use case. This patch makes LLD to warn only when incompatible export
options are given.

because I have no idea what "@12" suffix is, but without it the symbol won't
be resolved...
