Nick Kledzik 3011259a85 Rework how YAMLReader is layered on top of YAMLParser. Turn hand written 
recursive descent functions into one table driven parser.  Add proper
error recovery and reporting.  Add lots of test cases with semantics errors
and verify error messages.

Michael J. Spencer 60d835fa59 Add COFF reader. 
There are no tests for this yet because I still need to finish the
YAML -> COFF converter so we don't get binary files checked in.

Jay Foad 4d5e6cf906 Fix errors when building with GCC 4.6.1 -std=c++0x, which requires 
"friend class Foo;" instead of just friend Foo;".

Michael J. Spencer 34fbcb4cba MSVC fixes: 
* MSVC does not yet support initializer lists and uniform initialization.
* MSVC does not support flexible array members (And neither does C++).

The Mach-O writer test still fails with this, but it all compiles and
all other tests pass.

Nick Kledzik 20e652d627 Add way to represent static archives in yaml test cases. 
Add SharedLibraryFile and ArchiveLibraryFile subclasses of File.

Add command line options to lld-core to set various ResolverOptions settings
and added lots of test cases to verify the options work.

Nick Kledzik bb963dfb7e Factor out core linking options from Platform in a new ResolverOptions 
class.  Change Resolver to no longer use Platform.  Core linking
now issues errors directly.  We need to factor that out later.

Rework how Darwin executable writer finds "main" atom.  It now
adds to core linking an Atom  which has a Reference to "main".

Nick Kledzik b334be1ed2 First implementation of Darwin Platform. It is rich enough to generate 
a hello world executable from atoms.  There is still much to be flushed out.
Added one test case, test/darwin/hello-world.objtxt, which exercises the
darwin platform.

Added -platform option to lld-core tool to dynamically select platform.

Michael J. Spencer cfd029fd91 Rearange header order to match llvm style. This exposed some missing types. 
Also fix some Platform.h includes that somehow got missed last time.

llvm-svn: 153590
 2012-03-28 19:04:02 +00:00
Michael J. Spencer 87c2994e24 Move Platform.h to Core as Core depends on Platform.h, and the Platform 
library depends on Core. This breaks that cycle.

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.  

llvm-svn: 152269
 2012-03-08 00:18:30 +00:00
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.

Michael J. Spencer 846fe662ba If cont.size() is 0, the expression &_contentPool[result] has undefined 
behaivior because it indexes past the end of _contentPool.

Michael J. Spencer b2bd733593 Flexible array members are not in C++03, and MSVC doesn't support them. 
llvm-svn: 149426
 2012-01-31 21:45:53 +00:00
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. 
llvm-svn: 148256
 2012-01-16 22:03:44 +00:00
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
