x87 math evaluates everything with 80 bits precision, so we have to set FLT_EVAL_METHOD
to "2".

It should not be supported in C++11, since that uses the C99 standard
library, in which 'a' is a format specifier.

Promotion of the mask operand needs to be done using PromoteTargetBoolean, and not padded with garbage.

Matching MOVLP mask for AVX (265-bit vectors) was wrong.
The failure was detected by conformance tests.

block-level expr. Currently CXXConstructExpr is always added as a block-level
expr. This caused two problems for the analyzer (and potentially for the
CFG-based codegen).
1. We have no way to know whether a ctor call is base or complete.
2. We have no way to know the destination object being contructed.

Use isl_map_dim_max to extract the details of the changed
access relation. Only constant access functions are supported
now.

mach_override library.
In this case chances are that functions from it will be called from
mach_override_ptr() during ASan initialization.
This may lead to crashes (if those functions are instrumented) or
incorrect behavior (if the implementations differ).

The attached patch renames mach_override_ptr() into
__asan_mach_override_ptr() and makes the rest of the mach_override
internals hidden.

[asan] make sure __asan_report_* functions are not inlined (so that they are not optimized away and are kept in the resulting library). Patch by glider@google.com

[asan] remove the test for cfree. 'man cfree' says: 'This function should never be used.' and this function is not found on many OSes we support.

Add handling of x86_avx2_pmovmskb to computeMaskedBitsForTargetNode for consistency. Add comments and an assert for BMI instructions to PerformXorCombine since the enabling of the combine is conditional on it, but the function itself isn't.

it's a start!

there is non of that type to remove. This fixes a crasher in the particular
case where the instruction has metadata but no metadata storage in the context
(this is only possible if the instruction has !dbg but no other metadata info).
