Ahmed Bougacha 518cc6f811 MC CFG: Use data structures more appropriate than std::set. 
llvm-svn: 188888
 2013-08-21 07:28:51 +00:00
Ahmed Bougacha 58ed11341b MC CFG: Add an MCObjectSymbolizer in the MCObjectDisassembler. 
Used to detect calls to function symbol stubs (future commit).

llvm-svn: 188887
 2013-08-21 07:28:48 +00:00
Ahmed Bougacha b09d140f6b MC CFG: Add MCObjectDisassembler Mach-O implementation. 
Supports:
- entrypoint, using LC_MAIN.
- static ctors/dtors, using __mod_{init,exit}_func
- translation between effective and object load address, using
  dyld's VM address slide.

llvm-svn: 188886
 2013-08-21 07:28:44 +00:00
Ahmed Bougacha 0a89d2bf76 Add Mach-O entry_point_command declaration. 
llvm-svn: 188885
 2013-08-21 07:28:40 +00:00
Ahmed Bougacha 2eb593682a MC CFG: Add "dynamic disassembly" support to MCObjectDisassembler. 
It can now disassemble code in situations where the effective load
address is different than the load address declared in the object file.
This happens for PIC, hence "dynamic".

llvm-svn: 188884
 2013-08-21 07:28:37 +00:00
Ahmed Bougacha 57bc9677cd MC CFG: When disassembly is impossible, fallback to data bytes. 
This is the behavior of sequential disassemblers (llvm-objdump, ...),
when there is no instruction size hint (fixed-length, ...)

While there, also do some minor cleanup.

llvm-svn: 188883
 2013-08-21 07:28:32 +00:00
Ahmed Bougacha a376353346 MC CFG: Add MCObjectDisassembler support for entrypoint + static ctors. 
For now, this isn't implemented for any format.

llvm-svn: 188882
 2013-08-21 07:28:29 +00:00
Ahmed Bougacha ff12d02d51 MC CFG: Split MCBasicBlocks to mirror atom splitting. 
When an MCTextAtom is split, all MCBasicBlocks backed by it are
automatically split, with a fallthrough between both blocks, and
the successors moved to the second block.

llvm-svn: 188881

Ahmed Bougacha d3fc5b9648 MC CFG: Add a few needed methods, mainly MCModule::findFirstAtomAfter. 
While there, do some minor cleanup.

Ahmed Bougacha ffeecb5c80 MC: ObjectSymbolizer can now recognize external function stubs. 
Only implemented in the Mach-O ObjectSymbolizer.
The testcase sadly introduces a new binary.

Ahmed Bougacha 382a6d7562 MC: Refactor ObjectSymbolizer to make relocation/section info generation lazy. 
llvm-svn: 188878
 2013-08-21 07:28:07 +00:00
Ahmed Bougacha 630f9546c0 MC CFG: Add entrypoint address to MCModule. 
llvm-svn: 188877
 2013-08-21 07:28:02 +00:00
Ahmed Bougacha 3012ac5387 MC CFG: Add more MCFunction container methods (find, empty). 
llvm-svn: 188876
 2013-08-21 07:27:59 +00:00
Ahmed Bougacha 7bfc7da6e8 MC CFG: Keep pointer to parent MCModule in created MCFunctions. 
Also, drive-by cleaning around createFunction.

 2013-08-21 07:27:50 +00:00
Ahmed Bougacha c43aa4e88c MC CFG: Remap enough for the inserted instruction. 
llvm-svn: 188873
 2013-08-21 07:27:47 +00:00
Ahmed Bougacha 03efde5887 MC CFG: uint64_t -> size_t for vector size. 
llvm-svn: 188872
 2013-08-21 07:27:44 +00:00
Ahmed Bougacha 729ad51905 MC CFG: Add a getter for MCDataAtom's data array. 
While there, switch to new-style documentation.

David Majnemer ed89b5c6e7 DebugInfo: Do not use the DWARF Version for the .debug_pubnames or .debug_pubtypes version field 
Summary:
LLVM would generate DWARF with version 3 in the .debug_pubname and
.debug_pubtypes version fields.  This would lead SGI dwarfdump to fail
parsing the DWARF with (in the instance of .debug_pubnames) would exit
with:
dwarfdump ERROR:  dwarf_get_globals: DW_DLE_PUBNAMES_VERSION_ERROR (123)

This fixes PR16950.

Craig Topper 77df9cdd0b Synchronize VEX JIT encoding code with the MCJIT version. Fix a bug in the MCJIT code where CurOp was being incremented even if the operand it was pointing at wasn't used. Maybe only matters if there are any EVEX_K instructions that aren't VEX_4V.

Nadav Rotem 7efc04cb40 In LLVM FMA3 operands are dst, src1, src2, src3, however dst is not encoded as it is always src1. This was causing the encoding of the operands to be off by one.

Bill Wendling 707f601fa5 Move registering the execution of a basic block to the beginning rather than the end. 
There are situations which can affect the correctness (or at least expectation)
of the gcov output. For instance, if a call to __gcov_flush() occurs within a
block before the execution count is registered and then the program aborts in
some way, then that block will not be marked as executed. This is not normally
what the user expects.

If we move the code that's registering when a block is executed to the
beginning, we can catch these types of situations.
