Richard Smith 2362829734 tl;dr: Teach Clang to work around g++ changing its workaround to glibc's
implementation of C99's attempt to control the C++ standard. *sigh*


The C99 standard says that certain macros in <stdint.h>, such as SIZE_MAX,
should not be defined when the header is included in C++ mode, unless
__STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS are defined. The C++11 standard
says "Thanks, but no thanks" and C11 removed this rule, but various C library
implementations (such as glibc) follow C99 anyway.

g++ prior to 4.8 worked around the C99 / glibc behavior by defining
__STDC_*_MACROS in <cstdint>, which was incorrect, because <stdint.h> is
supposed to provide these macros too. g++ 4.8 works around it by defining
__STDC_*_MACROS in its builtin <stdint.h> header.

This change makes Clang act like g++ 4.8 in this regard: our <stdint.h> now
countermands any attempt by the C library to implement the undesired C99 rules,
by defining the __STDC_*_MACROS first. Unlike g++, we do this even in C++98
mode, since that was the intent of the C++ committee, matches the behavior
required in C11, and matches our built-in implementation of <stdint.h>.

Sean Callanan f8043fa527 Implemented materialization and dematerialization
for variables in the new Materializer.  This is
much easier now that the ValueObject API is solid.

I still have to implement reading bytes into a
ValueObject, but committing what I have so far.

This code is not yet used, so there will be fixes
when I switch the expression parser over to use the
new Materializer.

Bob Wilson 2b59395d0e Define Neon intrinsics as "static inline" to avoid warning. rdar://13108414
We had been defining Neon intrinsics as "static" with always_inline attributes.
If you use them from an extern inline function, you get a warning, e.g.:

static function 'vadd_u8' is used in an inline function with external linkage

This change simply adds the inline keyword to avoid that warning.

Quentin Colombet c313220b18 ARM: Correct printing of pre-indexed operands.
According to the ARM reference manual, constant offsets are mandatory for pre-indexed addressing modes.
The MC disassembler was not obeying this when the offset is 0.
It was producing instructions like: str r0, [r1]!.
Correct syntax is: str r0, [r1, #0]!.

This change modifies the dumping of operands so that the offset is always printed, regardless of its value, when pre-indexed addressing mode is used.

Anna Zaks 685e913d71 [analyzer] Print a diagnostic note even if the region cannot be printed.
There are few cases where we can track the region, but cannot print the note,
which makes the testing limited. (Though, I’ve tested this manually by making
all regions non-printable.) Even though the applicability is limited now, the enhancement
will be more relevant as we start tracking more regions.

Hal Finkel 1b58f335ca PPC: Remove (broken) nested implicit definition lists
TableGen will not combine nested list 'let' bindings into a single list, and
instead uses only the inner scope. As a result, several instruction definitions
were missing implicit register defs that were in outer scopes. This de-nests
these scopes and makes all instructions have only one let binding which sets
implicit register definitions.

Arnold Schwaighofer f9cea17f75 LoopVectorizer: integer division is not a reduction operation
Don't classify idiv/udiv as a reduction operation. Integer division is lossy.
For example : (1 / 2) * 4 != 4/2.

Example:

int a[] = { 2, 5, 2, 2}
int x = 80;

for()
  x /= a[i];

Scalar:
  x /= 2 // = 40
  x /= 5 // = 8
  x /= 2 // = 4
  x /= 2 // = 2

Vectorized:

 <80, 1> / <2,5> //= <40,0>
 <40, 0> / <2,2> //= <20,0>

 20*0 = 0

Manuel Klimek 1a18c40468 Revamps structural error detection / handling.
Previously we'd only detect structural errors on the very first level.
This leads to incorrectly balanced braces not being discovered, and thus
incorrect indentation.

This change fixes the problem by:
- changing the parser to use an error state that can be detected
  anywhere inside the productions, for example if we get an eof on
  SOME_MACRO({ some block <eof>
- previously we'd never break lines when we discovered a structural
  error; now we break even in the case of a structural error if there
  are two unwrapped lines within the same line; thus,
  void f() { while (true) { g(); y(); } }
  will still be re-formatted, even if there's missing braces somewhere
  in the file
- still exclude macro definitions from generating structural error;
  macro definitions are inbalanced snippets
