(clang/include/clang/Basic/StmtNodes.td, for instance, is tablegenned
from clang/include/clang/AST/CMakeLists.txt) so it is not contained on
the list of all .td files on the current source directory which is
used as the DEPENDS of the custom command. We must add the .td file to
the DEPENDS list of the custom command. Otherwise some .inc files are
not regenerated when the corresponding .td file changes.

When we are in code-completion mode, skip parsing of all function bodies except the one where the
code-completion point resides.
For big .cpp files like 'SemaExpr.cpp' the improvement makes a huge difference, in some cases cutting down
code-completion time -62% !
We don't get diagnostics for the bodies though, so modify the code-completion tests that check for errors.
See rdar://8814203.

(transforming each in turn) into calls into one central routine
(TransformExprs) that transforms a list of expressions. This
refactoring is preparatory work for pack expansions whose in an
expression-list.
No functionality change.

that are allowed to have metadata operands are intrinsic calls,
and the only ones that take metadata currently return void.
Just reject all void instructions, which should not be value
numbered anyway. To future proof things, add an assert to the
getHashValue impl for calls to check that metadata operands
aren't present.

nested values, so they can change and drop to null, which can
change the hash and cause havok.
It turns out that it isn't a good idea to value number stuff
with metadata operands anyway, so... don't.

FunctionDecl::setPure crashed a poor user's code.
Remove the use of this accessor when deserializing, along with several other in the neighborhood. Fixes rdar://8759653.

Replace "clang++" with "clang\+\+" because we have to escape regexp
special characters now. This is in preparation for changes to lit to
fix PR8199. Tests will fail until the lit part gets committed.

template argument (described by an expression, of course). For
example:
template<int...> struct int_tuple { };
template<int ...Values>
struct square {
typedef int_tuple<(Values*Values)...> type;
};
It also lays the foundation for pack expansions in an initializer-list.

don't have access to (e.g., fprintf, which needs the library type
FILE), fail with a warning and forget about the builtin
entirely. Previously, we would actually provide an error, which breaks
autoconf's super-lame checks for fprintf, longjmp, etc. Fixes PR8316.

capacity on the Visited SmallPtrSet. On 403.gcc, this is about a 4.5% speedup of
CodeGenPrepare time (which itself is 10% of time spent in the backend).
This is progress towards PR8889.
llvm-svn: 122741
improvement in the generated code, and speeds up 'opt -std-compile-opts'
compile time on 176.gcc from 24.84s to 23.2s (about 7%).
This also resolves a specific code quality issue in rdar://7352081 which
was generating poor code for:
int t(int a, int b) {
if (a & b & 1)
return a & b;
return 3;
}

The rationale is that after analyzing a function in the SCC, we may want to
modify it in a way that requires us to update its uses (f.e. to replace the
call with a constant) or its users (f.e. to call it with fewer arguments).
llvm-svn: 122739
update a callGraph when performing the common operation of splicing the body to
a new function and updating all callers (such as via RAUW).
No users yet, though this is intended for DeadArgumentElimination as part of
PR8887.
