Michael J. Spencer 64afcb4c6b Move everything over to TargetInfo.
I really would have liked to split this patch up, but it would greatly
complicate the lld-core and lld drivers having to deal with both
{Reader,Writer}Option and TargetInfo.

Chandler Carruth b5f3bd956c Replace the 'final' keyword with 'LLVM_FINAL' as GCC 4.6 doesn't support
the keyword.

If anyone cares deeply about the final optimizations with GCC, we might
want to add a version test to the LLVM definition, but I'm perfectly
happy with this just only firing under Clang and modern MSVC builds.

llvm-svn: 172898
2013-01-19 09:57:51 +00:00
Chandler Carruth 8b95c03fca Allow the LLD CMake build to work with -std=gnu++0x and -std=gnu++11 as
well as c++0x and c++11. This can be especially useful when building
with GCC in C++11 mode.

llvm-svn: 172897
2013-01-19 09:41:42 +00:00
Chandler Carruth 058761266d Fix the build with libstdc++ v4.6 on Linux by supplying an explicit move
assignment operator. There is an issue where classes with deleted copy
constructors and user defined move constructors end up with an
implicitly deleted copy constructor that is selected instead of the
implicit move constructor. This is a bit of a hack, but it allows me to
build LLD in a bootstrap with libstdc++ which is my primary goal.

Michael J. Spencer 8b3898af26 [ELF] Never allocate content to weak symbols as they may be merged away.
This is done by creating a new non-weak anonymous symbol and creating
an atom with content for that symbol. This is added after the weak symbol
so that they have the same address.

Nick Kledzik cc3d2dca60 Better tie together ContentType and Permissions.
Since most content types (e.g. typeCode) have a 
preferred Permission, add a function to do that mapping.
Then hook up to YAML Reader and Writer such that
the 'permissions:' key does not need to be specified unless
overriding what the content type prefers.
