Function declarations are now broken with the following preferences:
1) break amongst arguments.
2) break after return type.
3) break after (.
4) break before after nested name specifiers.
Options #2 or #3 are preferred over #1 only if a substantial number of
lines can be saved by that.

The behavior can be overridden by setting LIT_USE_INTERNAL_SHELL=0 in
the environment.
This fixes issues with /dev/null for me and brings the test suite time
down to 30s. =D

This required some tedious reordering to match clang's order.
Presumably these ObjC tests were generated based on llvm-gcc's output
ordering.

As packed comparisons in AVX/SSE produce all 0s or all 1s in each SIMD lane,
vector select could be simplified to AND/OR or removed if one or both values
being selected is all 0s or all 1s.

As these two instructions in AVX extension are privileged instructions for
special purpose, it's only expected to be used in inlined assembly.

This patch is revised based on patch from Victor Umansky
<victor.umansky@intel.com>. More cases are handled in X86's bool
simplification, i.e.
- SETCC_CARRY
- value is truncated to i1 with AND
As a by-product, PR5443 is also fixed.

to '-A'.
Add option '-a' / '--address' to disassemble which will find the
function that contains that address, and disassemble the entire function.

to the list of undefined atoms.
The processing of undefined atoms from dynamic libraries is controlled by
use-shlib-undefines command line option.
This patch also adds additional command line arguments to allow/disallow
unresolved symbols from shared libraries and mimics GNU ld behavior.

It was returning the loaded address of the section containing the relocation,
which really doesn't seem to be the intent of this function.

It's a kind of implicit conversion, which we generally drop, but
more importantly it's got very specific placement requirements.

Because of how predication in implemented on PPC (only for branches), I think
that this is the right thing to do. No functionality change intended.

For this source:
const int &ref = someStruct.bitfield;
We used to generate this AST:
DeclStmt [...]
`-VarDecl [...] ref 'const int &'
`-MaterializeTemporaryExpr [...] 'const int' lvalue
`-ImplicitCastExpr [...] 'const int' lvalue <NoOp>
`-MemberExpr [...] 'int' lvalue bitfield .bitfield [...]
`-DeclRefExpr [...] 'struct X' lvalue ParmVar [...] 'someStruct' 'struct X'
Notice the lvalue inside the MaterializeTemporaryExpr, which is very
confusing (and caused an assertion to fire in the analyzer - PR15694).
We now generate this:
DeclStmt [...]
`-VarDecl [...] ref 'const int &'
`-MaterializeTemporaryExpr [...] 'const int' lvalue
`-ImplicitCastExpr [...] 'int' <LValueToRValue>
`-MemberExpr [...] 'int' lvalue bitfield .bitfield [...]
`-DeclRefExpr [...] 'struct X' lvalue ParmVar [...] 'someStruct' 'struct X'
Which makes a lot more sense. This allows us to remove code in both
CodeGen and AST that hacked around this special case.
The commit also makes Clang accept this (legal) C++11 code:
int &&ref = std::move(someStruct).bitfield

Moving over to source-regex might be a good idea, but it’s not what we really want to test. Ideally, we would set a regex breakpoint to find the right line, then delete it and set one by file and line with the right line info from before.

information about each variable that needs to
be materialized for an expression to work. The
next step is to migrate all materialization code
from ClangExpressionDeclMap to Materializer, and
to use it for variable materialization.

Add support for the COFF relocation types IMAGE_REL_I386_DIR32NB and
IMAGE_REL_AMD64_ADDR32NB for 32- and 64-bit respectively. These are
similar to normal 4-byte relocations except that they do not include
the base address of the image.
Image-relative relocations are used for debug information (32-bit) and
SEH unwind tables (64-bit).
A new MCSymbolRef variant called 'VK_COFF_IMGREL32' is introduced to
specify such relocations. For AT&T assembly, this variant can be accessed
using the symbol suffix '@imgrel'.
