This should replace uses of:

  A(const &A); // DO NOT IMPLEMENT

Suggest use of __attribute__((visibility("hidden")))
on declaration instead. // rdar://7703982

Changed the alignment of an LValue to be 64 bits so that we can handle
alignment values up to half of a 64-bit address space.

Fix another roundToIntegral bug where very large values could become infinity.  Problem and solution identified by Steve Canon.

This is a reapplication of r161914 now that the scoping issue has been resolved
in r161966.

TableGen sometimes synthesizes missing sub-register indexes. Emit these
indexes as enumerators in the target namespace along with the
user-defined ones.

Also take this opportunity to stop creating new Record objects for
synthetic indexes.

Use vld1/vst1 to load/store f64 if alignment is < 4 and the target allows unaligned access. rdar://12091029

A similar issue to the previous commit, introduced by r161915.

llvm-svn: 161961

With reinterpret_cast, we can get completely unrelated types in a region
hierarchy together; this was resulting in CXXBaseObjectRegions being layered
directly on an (untyped) SymbolicRegion, whose symbol was from a completely
different type hierarchy. This was what was causing the internal buildbot to
fail.

Reverts r161911, which merely masked the problem.

When predicating this instruction:

  Rd = ADD Rn, Rm

We need an extra operand to represent the value given to Rd when the
predicate is false:

  Rd = ADDCC Rfalse, Rn, Rm, pred

The Rd and Rfalse operands are different registers while in SSA form.
Rfalse is tied to Rd to make sure they get the same register during
register allocation.

Previously, Rd and Rn were tied, but that is not required.

Compare to MOVCC:

  Rd = MOVCC Rfalse, Rtrue, pred

Introduce asan_intercepted_functions.h which contains the declarations wrapped functions and their wrappers.
Those declarations are going to be shared between asan_interceptors.cc and the dynamic runtime library on Mac OS.

[ASan] lit tests: use nm instead of llvm-nm, until llvm-nm becomes usable on Mac. Port output test change in r161948 to lit

Move the prototype of __CFInitialize to asan_mac.h so that asan_malloc_mac.cc may use it in the dynamic library mode.

instruction to something absurdly high, while setting the probability of
branching to the 'unwind' destination to the bare minimum. This should set cause
the normal destination's invoke blocks to be moved closer to the invoke.

llvm-svn: 161944

Export CheckFailed, asan_malloc, asan_free, asan_memalign, AsanStackTrace::CompressStack, AsanStackTrace::UncompressStack from the dynamic runtime library.

llvm-svn: 161943

Make __asan::asan_{malloc,free,memalign} globally visible, so that the dynamic version of the runtime will export them.

[ASan] Port (the last one) tricky interface_test to lit, and a *huge* chunks of boilerplate to run tests for 32/64 bits and all optimization levels. Alas, lit doesn't support for loops in RUN-lines...
