the bug.

the load, then it may be legal to transform the load and store to integer
load and store of the same width.

This is done if the target specified the transformation as profitable. e.g.
On arm, this can transform:
vldr.32 s0, []
vstr.32 s0, []

to

ldr r12, []
str r12, []

diagnostics of Clang AST classes for the purpose of
debugging the types LLDB produces for DWARF objects.

The ASTDumper is currently only used in log output
if you enable verbose mode in the expression log:

log enable -v lldb expr

Its output then appears in the log for external
variables used by the expr command.

Macros frequently contain extra '()' to make instantiation less error prone.

BumpPtrAllocator, rather than manually new/delete'ing them. This
optimization also allows us to avoid allocating memory for and copying
constant strings (e.g., "return", "class").

This also required embedding the priority and availability of results
within the code completion string, to avoid extra memory allocation
within libclang.

[AVX] Implement EnforceSmallerThan for mixed int/fp type lists.  This
makes type checking for extract_subvector and insert_subvector more
robust and will allow stricter typechecking of more patterns in the
future.

This change handles int and fp as disjoint sets so that it will
enforce integer types to be smaller than the largest integer type and
fp types to be smaller than the largest fp type.  There is no attempt
to check type sizes across the int/fp sets.

Add temporary hack to -Wuninitialize to create a separate CFG (for C++ code) that doesn't include implicit dtors.

Implicit dtors confuse the ad hoc path-sensitivity of UninitializedValuesV2.cpp.  This isn't
the ideal solution, as it will directly impact compile time, but should significantly reduce
the noise of -Wuninitialized on some code bases.

This immediately "fixes" the false positive reported in PR 9063, although this
isn't the right fix in the long run.

llvm-svn: 124667

Enhance -Wuninitialized to better reason about || and &&, tracking dual dataflow facts and properly merging them.
