(clang/driver) command line arguments (including the source file).
 - The arguments are expected to include the source file.

 - The idea is that even though this is a somewhat odd API, its the form which
   many tools can most easily use (for example, by interposing with the compiler).

Also, switch index-test's -ast-from-source to use this entry point, and provide
a -arg command line argument which can be used to test that the command line
arguments are handled correctly.

Exit the command line into <built-in> instead of going directly from the command line to the input file.

We passed <built-in> on the way in, so we should pass it again on the way out.

llvm-svn: 90250

Also, add an -ast-from-source option to index-test which allows index-test to
run on source files directly.

Add CodeGenOptions::{SoftFloat,FloatABI}, and update the all the (far too many) places to use this instead of using the backend -soft-float and -float-abi= options.

stat a file but where mmaping it fails.  In this case, we emit an
error like:
t.c:1:10: fatal error: error opening file '../../foo.h'

instead of "cannot find file".

function names outside of templates - they'll probably cause some damage there as
they're largely untested.

Move LLVM backend options to explicit clang-cc / clang -cc1 options, which we then manually pass to the command line library; eventually the latter grossness should be fixed by a real API when creating the target machine.

Factor out a LangStandard class and coalesce the information about the standards into LangStandards.def

Call GRExprEngine::setTransferFunctions() after registering all Checkers.  This allows GRTransferFuncs::RegisterChecks() to always be called after all checkers have been registered.

Consolidate logic in ActionInlineCall by having it call ActionGRExprEngine instead of replicating most of its logic (and missing pieces).

llvm-svn: 89886

Make RegisterInternalChecks() part of GRExprEngine's private implementation by making it a static function within GRExprEngine.cpp.

Register internal checks with GRExprEngine when it is constructed, not manually in AnalysisConsumer.cpp.

All statements that involve conditions can now hold on to a separate
condition declaration (a VarDecl), and will use a DeclRefExpr
referring to that VarDecl for the condition expression. ForStmts now
have such a VarDecl (I'd missed those in previous commits).

Also, since this change reworks the Action interface for
if/while/switch/for, use FullExprArg for the full expressions in those
expressions, to ensure that we're emitting

Note that we are (still) not generating the right cleanups for
condition variables in for statements. That will be a follow-on
commit.

llvm-svn: 89817

cleanups for while loops: 

1) Make sure that we destroy the condition variable of a while statement each time through the loop for, e.g.,

   while (shared_ptr<WorkInt> p = getWorkItem()) {
         // ...
         }

2) Make sure that we always enter a new cleanup scope for the body of the while loop, even when there is no compound expression, e.g.,

   while (blah)
     RAIIObject raii(blah+1);

llvm-svn: 89800

make sure that this variable is destroyed when we exit the switch
statement.

llvm-svn: 89776

rather than burying it in a CXXConditionDeclExpr (that occassionally
hides behind implicit conversions). Similar changes for
switch, while, and do-while will follow, then the removal of
CXXConditionDeclExpr. This commit is the canary.
