Michael J. Spencer 563d33a6f1 [ELF] Read IFUNC symbols correctly as typeResolver. 
llvm-svn: 173299

 2013-01-23 20:03:10 +00:00
Shankar Easwaran c142874c9c change from using 2 bits to 4 bits, as 2 bits arent enough to hold the enumeration OutputKind

 2013-01-23 15:11:22 +00:00
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.

Shankar Easwaran 58ad41b563 change enum class to enum, as g++ doesnot support bitfields with enumerated classes with c++11 flag set 
llvm-svn: 173166
 2013-01-22 14:58:51 +00:00
Shankar Easwaran c7176430dc it looks like g++ 4.7.2 doesnot like bit fields when the type is a enumeration (Throws an error as bit-field with non integral type) 
llvm-svn: 173125

Michael J. Spencer 359e09d4f5 [docs] Document lld's usage of C++11 features.

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.

 2013-01-09 20:10:30 +00:00
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.

Nick Kledzik 1a6615dc88 Sources now require C++11 to build. 
Add first linker pass (StubsPass) which looks for calls to shared library
symbols and replaces them with calls to a StubAtom.  On ELF system, a "stub"
is a PLT entry.  Added a simple test case.

Pass a Platform object to YAML reader and writer for converting fixup kinds 
between names and values.

Change output of Resolver to be a File object instead of a vector of Atoms.
Thus, passes operate on a File instead of just Atoms.

Rework how to walk through a File's Atoms. Now iterator based instead of 
a method that visits each atom.

Nick Kledzik 6bc04c6904 Add support for SharedLibraryAtoms (proxy atoms for exported symbols from a 
shared library) and AbsoluteAtoms (proxy atoms for absolute address (e.g. ROM)).
Redesign weak importing as can-be-null-at-runtime and can-be-null-at-build-time.
Add lots of test cases for all the above.

Nick Kledzik 55fd6beb00 First chunk of native object file reader/writer. The lld-core tool now reads YAML file, links, writes that out as native object format, then reads that native file, then writes the YAML to stdout. Thus the test suite tests both YAML reading/writing as well as native object file reading/writing.

Nick Kledzik f4fb2c5ac8 A couple of big refactorings: 1) Move most attributes of Atom down to DefinedAtom, so only atoms representing definitions need to implement them. 2) Remove definitionTentative, definitionWeak, mergeDuplicates, and autoHide. Replace with merge and interposable attributes. 3) Make all methods on Atom be virtual so that future object file readers can lazily generated attributes
