vectorizing loops with memory accesses to non-zero address spaces. It
simply dropped the AS info. Fixes PR16306.

To better support per-translation unit replacements, any real work is being
moved out of ActionFactory and into Transform. In this revision, that means
file override application.

For simplification, Transform no longer inherits from SourceFileCallbacks.
TransformTest required updating as a result.

Make use of getTypeSizeInChars to detect structs/unions of zero size. It allows
more accurate detection of types of zero size. It however has a side effect -
sequence of used types may change, that is why the test 'override-layout' was
modified.

Fix a problem in ExpressionParser leading to trailing comments affecting indentation of an expression after a line break.

Summary:
E.g. the second line in 

return aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
           b; //

is indented 4 characters more than in

return aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa +
       b;

The untemplated implementation of getParents() doesn't need to be in a
header file.

RecursiveASTVisitor.h is full of repeated macro expansion.  Moving this
include to ASTContext.cpp speeds up compilation of
LambdaMangleContext.cpp, a small C++ file with few includes, from 3.7s
to 2.8s for me locally.  I haven't measured a full build, but it can't
hurt.

I had to fix a few static analyzer files that were depending on
transitive includes of C++ AST headers.

This broke for example the 'not' utility, if a directory called
'FileCheck' is executable and in the path before the actual 'FileCheck'.

This patch steals the implementation of the "old" PathV1 canExecute
implementation:
- checks for R_OK (file readable): this is necessary for executing
  scripts; we should not regress here unless we have good reasons
- checks for S_ISREG; if we want to get rid of this, we'd need to
  change all callers who already made the assumption when depending
  on Path V1.

llvm-objdump should provide some way of printing out the addends present in the
.rela sections for debugging purposes if nothing else.

llvm-svn: 184072

This change adds functionality to add more sections like .gcc_except_table,
.data.rel.local, .data.rel.ro into the default section map, so that they are
all merged into appropriate output sections.

This also makes c++ static binaries comparable to what you get with the default
linker.

Adds a test for testing the functionality.

Frame index handling is now target-agnostic, so delete the target hooks
for creation & asm printing of target-specific addressing in DBG_VALUEs
and any related functions.

llvm-svn: 184067

Rather than using the full power of target-specific addressing modes in
DBG_VALUEs with Frame Indicies, simply use Frame Index + Offset. This
reduces the complexity of debug info handling down to two
representations of values (reg+offset and frame index+offset) rather
than three or four.

Ideally we could ensure that frame indicies had been eliminated by the
time we reached an assembly or dwarf generation, but I haven't spent the
time to figure out where the FIs are leaking through into that & whether
there's a good place to convert them. Some FI+offset=>reg+offset
conversion is done (see PrologEpilogInserter, for example) which is
necessary for some SelectionDAG assumptions about registers, I believe,
but it might be possible to make this a more thorough conversion &
ensure there are no remaining FIs no matter how instruction selection
is performed.

llvm-svn: 184066

This currently unused function appeared to be asserting in the wrong
direction - DebugValues are never definitions of registers, only uses.
Curiously we don't perform any of these checks for the more common (&
actually used) case of MachineOperand::CreateReg (or other Create
functions).
