9ef901972f CMake: Introduce LLVM_CLANG_SOURCE_DIR, "tools/clang" by default. Clang will not be built if LLVM_CLANG_SOURCE_DIR="" or ${LLVM_CLANG_SOURCE_DIR}/CMakeLists.txt is not found.

dab0c92a4f Add X86 feature detection support for BMI instructions. Added new cpuid function for accessing leafs with sub leafs specified in ECX. Also added code to keep track of the max cpuid level supported in both basic and extended leaves and qualified the existing cpuid calls and the new call to leaf 7.

bca9567da0 Let this test pass even if 'int' is somewhere in its directory path. 
On my machine, grep matched:

  ; ModuleID = '/Volumes/MacintoshHD2/src/chrome-git/src/third_party/llvm/test/Linker/2011-08-18-unique-debug-type.ll'
  !9 = metadata !{i32 720932, null, metadata !"int", null, i32 0, i64 32, i64 32, i64 0, i32 0, i32 5} ; [ DW_TAG_base_type ]

Explicitly filter out the ModuleID line.

0c20486517 Add a bad char heuristic to StringRef::find. 
Based on Horspool's simplified version of Boyer-Moore. We use a constant-sized table of
uint8_ts to keep cache thrashing low, needles bigger than 255 bytes are uncommon anyways.

The worst case is still O(n*m) but we do a lot better on the average case now.

0ef2965563 Fix SCEVExpander assert during LSR: "argument of incompatible type". 
Just because we're dealing with a GEP doesn't mean we can assert the
SCEV has a pointer type. The fix is simply to ignore the SCEV pointer
type, which we really didn't need.
Fixes PR11138 webkit crash.

f7ee2603c2 Revert r142046, "Fix for llvm::sys::getHostTriple on Windows. Instead of relying on the triple" 
It extremely breaks builds when optimization is enabled. Twine should not hold temporary objects.

By the way, I might feel sad if I saw "i786-" "i1586-" or "iF86-".

7cc89bde59 Fix indvars randomness by removing iteration over a map. 
I rewrote the algorithm a while back so it doesn't require map lookup,
but neglected to change the data structure. This was caught by
llvm-gcc self host, not because there's anything special about
llvm-gcc, but because it is the only test for nondeterminism we
currently have. Unit tests don't work well for everything; we should
always try to have a nondeterminism stress test running.

Fixes PR11133: llvm-gcc self host .o mismatch after enable-iv-rewrite=false

0dd89843fc Clear out the landing pad to call site map for each function. 
This isn't put into the 'clear()' method because the information needs to stick
around (at least for a little bit) after the selection DAG is built.

b0f487f367 Mark tADDrSPi as having side effects again. 
It really doesn't, but when r141929 removed the hasSideEffects flag from
this instruction, it caused miscompilations.  I am guessing that it got
moved across a stack pointer update.

Also clear isRematerializable after checking that this instruction is
in fact never rematerialized in the nightly test suite.

42a60003a1 Thumb1 does not support dynamic stack realignment. 
rdar://10288916 is tracking this fix.

In the past, instcombine and other passes were promoting alloca alignment past
the natural alignment, resulting in dynamic stack realignment.  Lang's work now
prevents this from happening (LLVM commit r141599).  Now that this really 
shouldn't happen report a fatal error rather than silently generate bad code.

4191045be4 Mark the invoke call instruction as implicitly defining the callee-saved registers. 
The callee-saved registers cannot be live across an invoke call because the
control flow may continue along the exceptional edge. When this happens, all of
the callee-saved registers are no longer valid.
