make into the last commit.
Also, update the test-generation script to generate an exhaustive test for
align_to_end as well, and include the generated test.

This is in preparation for using this to construct the function type for
pointers to member functions to include the implicit/artificial 'this'
parameter in that case as well. (feedback from GDB indicates that this might be
all that's necessary to get it to behave well with Clang's pointer-to-member
function debug output)

small loops. On small loops post-loop that handles scalars (and runs slower) can take more time to execute than the
rest of the loop. This patch disables widening of loops with a small static trip count.

This fixes the URL permanence of that URL. This is a bit of a hack. See
the FIXME in the patch for what the "real" solution should be.

o. X/C1 * C2 => X * (C2/C1) (if C2/C1 is neither special FP nor denormal)
o. X/C1 * C2 -> X/(C1/C2) (if C2/C1 is either specical FP or denormal, but C1/C2 is a normal Fp)
Let MDC denote multiplication or dividion with one & only one operand being a constant
o. (MDC ± C1) * C2 => (MDC * C2) ± (C1 * C2)
(so long as the constant-folding doesn't yield any denormal or special value)

proposal. This leaves the strings in the skeleton die as strp,
but in all dwo files they're accessed now via DW_FORM_GNU_str_index.
Add support for dumping these sections and modify the fission-cu.ll
testcase to have the correct strings and form. Fix a small bug
in the fixed form sizes routine that involved out of array accesses
for the table and add a FIXME in the extractFast routine to fix
this up.

code generation. Variables addressed through a GlobalAlias were not being
handled, and variables with available_externally linkage were treated
incorrectly. The patch contains two new tests to verify the correct code
generation for these cases.
llvm-svn: 171778
DenseMap and the lookups associated with it.
Instead of lexing for preprocessor tokens, associating the annotation with the location in a map,
and later lookup in the map in order to adjust the cursor annotation, just annotate the cursor
while lexing for preprocessor tokens.
llvm-svn: 171775
Previously type/storage qualifiers would not be annotated as the declaration they belonged to.
Just use the resulting source range of getRawCursorExtent() which is more correct
than what AnnotateTokensWorker::Visit() was adjusting it to.

this was ever a macro name and return a specific CXCursor_MacroExpansion cursor in such a case,
instead of the generic CXCursor_MacroDefinition.
Checking for macro name makes sure the identifier is not part of the identifier list in a
function macro.
While, in general, resolving identifiers in macro definitions to other macros may not be completely accurate,
it greatly improves functionality such as give-me-the-definition-of-this, which was not working at all
inside macro definitions.

Better handle the blacklisting of known bad deallocators when symbol
escapes through a call to CFStringCreateWithBytesNoCopy.
Addresses radar://12702952.
llvm-svn: 171770
When a property is "inherited" through both a parent class and directly
through a protocol, we should not require the child to invalidate it
since the backing ivar belongs to the parent class.
(Fixes radar://12913734)
llvm-svn: 171769
This is necessary not only for representing empty ranges, but for handling
multibyte characters in the input. (If the end pointer in a range refers to
a multibyte character, should it point to the beginning or the end of the
character in a char array?) Some of the code in the asm parsers was already
assuming this anyway.
llvm-svn: 171765
turning a code like this:
if (foo)
free(foo)
into that:
free(foo)
Move a call to free from basic block FB into FB's predecessor, P,
when the path from P to FB is taken only if the argument of free is
not equal to NULL.
Some restrictions apply on P and FB to be sure that this code motion
is profitable. Namely:
1. FB must have only one predecessor P.
2. FB must contain only the call to free plus an unconditional
branch to S.
3. P's successors are FB and S.
Because of 1., we will not increase the code size when moving the call
to free from FB to P.
Because of 2., FB will be empty after the move.
Because of 2. and 3., P's branch instruction becomes useless, so as FB
(simplifycfg will do the job).

Previous indent:
class A {
}
a;
void f() {
};
With this patch:
class A {
} a;
void f() {
}
;
The patch introduces a production for classes and structs, and parses
the rest of the line to the semicolon after the class scope.
This allowed us to remove a long-standing wart in the parser that would
just much the semicolon after any block.
Due to this suboptimal formating some tests were broken.
Some unrelated formatting tests broke; those hit a bug in the ast
printing, and need to be fixed separately.
