integral promotions to both its underlying type and to its underlying type's
promoted type. This matters now that boolean conversions aren't permitted in
converted constant expressions (a la DR1407): an enumerator with a fixed
underlying type of bool still can be.

should be fine to use it without further explanations in the attached
paragraph, so the warning about empty paragraph was turned off for it.

- Enhance the fix to PR12312 to support wider integer, such as 256-bit
integer. If more than 1 fully evaluated vectors are found, POR them
first followed by the final PTEST.

warning to an error. C++ bans it, and both GCC and EDG diagnose it as
an error. Microsoft allows it, so we still warn in Microsoft
mode. Fixes <rdar://problem/11135644>.

- Find a legal vector type before casting and extracting element from it.
- As the new vector type may have more than 2 elements, build the final
hi/lo pair by BFS pairing them from bottom to top.

middle of UTF-8 characters, and avoid walking to such positions when adjusting
column ranges for display. Fixes a couple of hangs when rendering diagnostics.

Add a PatFrag to match X86tcret using 6 fixed registers or less. This
avoids folding loads into TCRETURNmi64 using 7 or more volatile
registers.

crazy case where dispatch_once gets redefined as a macro that calls
_dispatch_once (which calls the real dispatch_once). Users want to
see the warning in their own code.

48-bit if necessary, in order to reduce the generated code size.
We have 900 cases not covered by OpcodeInfo in ATT AsmWriter and more in Intel
AsmWriter and ARM AsmWriter.
This patch reduced the clang Release build size by 50k, running on a Mac Pro.

by xoring the high-bit. This fails if the source operand is a vector because we need to negate
each of the elements in the vector.

are within the lifetime zone. Sometime legitimate usages of allocas are
hoisted outside of the lifetime zone. For example, GEPS may calculate the
address of a member of an allocated struct. This commit makes sure that
we only check (abort regions or assert) for instructions that read and write
memory using stack frames directly. Notice that by allowing legitimate
usages outside the lifetime zone we also stop checking for instructions
which use derivatives of allocas. We will catch less bugs in user code
and in the compiler itself.
