Howard Hinnant fc88dbd298 Debug mode for string. This commit also marks the first time libc++ debug-mode has found a bug (found one in regex). Had to play with extern templates a bit to get this to work since string is heavily used within libc++.dylib.

Jordan Rose 4c55d45b13 Respect -Wnewline-eof even in C++11 mode.
If the user has requested this warning, we should emit it, even if it's not
an extension in the current language mode. However, being an extension is
more important, so prefer the pedantic warning or the pedantic-compatibility
warning if those are enabled.

Daniel Jasper 0649d36172 clang-format: Fix indentation relative to unary expressions.
This should be done, only if we are still in the unary expression's
scope.

Before:
  bool aaaa = !aaaaaaaa(  // break
                   aaaaaaaaaaa);
  *aaaaaa = aaaaaaa( // break
       aaaaaaaaaaaaaaaa);

After:
  bool aaaa = !aaaaaaaa(  // break
                   aaaaaaaaaaa); // <- (unchanged)
  *aaaaaa = aaaaaaa( // break
      aaaaaaaaaaaaaaaa); // <- (no longer indented relative to "*")

Evgeniy Stepanov d42863cc1f [msan] Fix handling of va_arg overflow area on x86_64.
The code was erroneously reading overflow area shadow from the TLS slot,
bypassing the local copy. Reading shadow directly from TLS is wrong, because
it can be overwritten by a nested vararg call, if that happens before va_start.

Richard Sandiford a481f58542 [SystemZ] Prefer LHI;ST... over LAY;MV...
If we had a store of an integer to memory, and the integer and store size
were suitable for a form of MV..., we used MV... no matter what.  We could
then have sequences like:

    lay %r2, 0(%r3,%r4)
    mvi 0(%r2), 4

In these cases it seems better to force the constant into a register
and use a normal store:

    lhi %r2, 4
    stc %r2, 0(%r3, %r4)

since %r2 is more likely to be hoisted and is easier to rematerialize.

Richard Sandiford 37cd6cfba2 Turn MipsOptimizeMathLibCalls into a target-independent scalar transform
...so that it can be used for z too.  Most of the code is the same.
The only real change is to use TargetTransformInfo to test when a sqrt
instruction is available.

The pass is opt-in because at the moment it only handles sqrt.

Pavel Labath 02b64d46a0 [analyzer] Refactor conditional expression evaluating code
Summary:
Instead of digging through the ExplodedGraph, to figure out which edge brought
us here, I compute the value of conditional expression by looking at the
sub-expression values.

To do this, I needed to change the liveness algorithm a bit -- now, the full
conditional expression also depends on all atomic sub-expressions, not only the
outermost ones.

David Majnemer 61c39a1ccd Sema: Properly support Microsoft-mode template arguments
Summary:
There were two things known to be wrong with our implementation of MSVC
mode template arguments:

- We didn't properly handle __uuidof/CXXUuidofExpr and skipped all type
  checking completely.
- We didn't allow for MSVC's extension of allowing certain constant
  "foldable" expressions from showing up in template arguments.
  They allow various casts dereference and address-of operations.
  We can make it more general as we find further peculiarities but this
  is the known extent.

Sean Callanan ffc12850cf Make sure that ClangExpressionDeclMap doesn't
live beyont parsing.  This is important because
all the ClangASTImporter::Minions for a parser's
ASTContext are cleared when ClangExpressionDeclMap
is deleted.

This resolves many hard-to-reproduce crashes,
especially ones involving breakpoint conditions.

Michael Gottesman 823aaffd37 Update StripDeadDebugInfo to use DebugInfoFinder so that it is no longer stale to the point of not working and more resilient to debug info changes.
The current version of StripDeadDebugInfo became stale and no longer actually
worked since it was expecting an older version of debug info.

This patch updates it to use DebugInfoFinder and the modern DebugInfo classes as
much as possible to make it more redundent to such changes. Additionally, the
only place where that was avoided (the code where we replace the old sets with
the new), I call verify on the DIContextUnit implying that if the format changes
and my live set changes no longer make sense an assert will be hit. In order to
ensure that that occurs I have included a test case.

The actual stripping of the dead debug info follows the same strategy as was
used before in this class: find the live set and replace the old set in the
given compile unit (which may contain dead global variables/functions) with the
new live one.
