Dale Johannesen 6271b0a83c Temporarily revert functionality change from my previous patch;
it is too aggressive.

Ted Kremenek 53532c1fda In RewriteFunctionBody, using DeclStmt::decl_iterator to rewrite the Decls in a DeclStmt instead of using getDecl() to fetch the first Decl.
Steve: Please review this patch.  'make test' passes, and my cursory scan of the rewriter leads me to believe this doesn't break anything, but I'm not sure.

Ted Kremenek 4db44b62ad Don't use DeclStmt::getDecl(); this will eventually disappear. Just fetch the first decl using the DeclStmt::decl_iterator.

Ted Kremenek 704a2505db In EmitDeclStmt: use DeclStmt::const_decl_iterator instead of walking the scoped decl chain.

Ted Kremenek 15e6b40832 Added PrintRawDeclStmt; use this method to print out DeclStmt instead of using PrintRawDecl (which falsely assumes DeclStmts have only one Decl).

Argyrios Kyrtzidis 9a1191c047 Implement support for C++ direct initializers in declarations, e.g. "int x(1);".
This is how this kind of initializers appear in the AST:
-The Init expression of the VarDecl is a functional type construction (of the VarDecl's type).
-The new VarDecl::hasCXXDirectInitializer() returns true.

e.g, for "int x(1);":
-VarDecl 'x' has Init with expression "int(1)" (CXXFunctionalCastExpr).
-hasCXXDirectInitializer() of VarDecl 'x' returns true.

A major benefit is that clients that don't particularly care about which exactly form was the initializer can handle both cases without special case code.
Note that codegening works now for "int x(1);" without any changes to CodeGen.

Matthijs Kooijman cbe5e16eb5 Allow scalarrepl to treat an all-zero GEP just as bitcast.
This includes not marking a GEP involving a vector as unsafe, but only when it
has all zero indices. This allows scalarrepl to work in a few more cases.

Duncan Sands bae7a517cc Actually run Obj-C++ tests if llvm-gcc supports.
Before there were two problems: (1) configure
turned "obj-c++" into "obj" in the langs line;
(2) the dejagnu library called it objc++ not
obj-c++.
Now the problem is that some of these tests don't
pass!

Duncan Sands 2a1d8bace1 Clarify the relationship between byval and readonly/
readnone.  Make clearer that readnone functions do not
dereference pointer arguments.  Do not use the highly
ambiguous "side-effects" in the readonly description
(since such functions can have control flow side-effects,
such as throwing an exception, or looping for ever).

Chris Lattner 1b0a00a4c9 __CONSTANT_CFSTRINGS__ should be defined even in C mode, otherwise the CFSTR
won't expand to the builtin.  This fixes rdar://6248329

Chris Lattner a97132a9c4 Make sema and codegen allow __builtin___CFStringMakeConstantString as a valid
constant lvalue.  Implement this in codegen by moving the code out of CGBuiltin
into EmitConstantExpr.

Chris Lattner 24355b5240 always try to fold a builtin before emitting it. In the future
it is possible that a builtin could sometimes be folded (e.g. __builtin_clz)
if it's operand is a constant.

2008-10-06 06:56:41 +00:00
Chris Lattner b7c86a211c Remove the 'C' / isConstantExpr flag on builtins. Code should never
depend on the value of this flag, it should depend on whether 
tryEvaluate is able to *actually* fold a builtin.

Chris Lattner cb13691a62 Add a Expr::isEvaluatable method, eliminate isBuiltinConstantExpr

what we can constant fold.

Chris Lattner a1518b1dfe remove some code where CGBuiltin folds constants, and use tryEvaluate to
do it instead.  We should still handle __builtin_nan etc, but don't yet.
This fixes incorrect evaluation of __builtin_constant_p, a FIXME.

llvm-svn: 57156
2008-10-06 06:09:18 +00:00
Chris Lattner e50e90142e instead of making codegen try to know about all of the builtins to generate
constants for them, just use the constant evaluator to do the job.  This
also fixes crashes on 'unknown constant builtins'.

Chris Lattner c43467526d "Enhance" CheckArithmeticConstantExpression to accept ?: with a constant
condition as a constant even if the unevaluated side is a not a constant.
We don't do this when extensions are off, and we emit a warning when this 
happens:

t.c:22:11: warning: expression is not a constant, but is accepted as one by GNU extensions
short t = __builtin_constant_p(5353) ? 42 : somefunc();
          ^                                 ~~~~~~~~~~

suggestions for improvement are welcome.  This is obviously horrible, but
is required for real-world code.

Chris Lattner 4deaa4ea24 Add a comment that describes tryEvaluate. Make tryEvaluate fold
__builtin_constant_p properly, and add some scaffolding for
FloatExprEvaluator to eventually handle huge_val and inf.
