Douglas Gregor ae2fbad373 Updated IdentifierResolver to deal with DeclarationNames. The names of
C++ constructors, destructors, and conversion functions now have a
FETokenInfo field that IdentifierResolver can access, so that these
special names are handled just like ordinary identifiers. A few other
Sema routines now use DeclarationNames instead of IdentifierInfo*'s.

To validate this design, this code also implements parsing and
semantic analysis for id-expressions that name conversion functions,
e.g.,

  return operator bool();

The new parser action ActOnConversionFunctionExpr takes the result of
parsing "operator type-id" and turning it into an expression, using
the IdentifierResolver with the DeclarationName of the conversion
function. ActOnDeclarator pushes those conversion function names into
scope so that the IdentifierResolver can find them, of course.

In that patch I added a bogus type promotion for unary '!'.

The real bug was more fallout from edges cases with compound assignments and conjured symbolic values.  Now the conjured value has the type of the LHS expression, and we do a promotion to the computation type.  We also now correctly do a conversion from the computation type back to the LHS type.

2008-11-14 18:21:25 +00:00
Douglas Gregor 993603d80d Add a new expression node, CXXOperatorCallExpr, which expresses a
function call created in response to the use of operator syntax that
resolves to an overloaded operator in C++, e.g., "str1 +
str2" that resolves to std::operator+(str1, str2)". We now build a
CXXOperatorCallExpr in C++ when we pick an overloaded operator. (But
only for binary operators, where we actually implement overloading)

I decided *not* to refactor the current CallExpr to make it abstract
(with FunctionCallExpr and CXXOperatorCallExpr as derived
classes). Doing so would allow us to make CXXOperatorCallExpr a little
bit smaller, at the cost of making the argument and callee accessors
virtual. We won't know if this is going to be a win until we can parse
lots of C++ code to determine how much memory we'll save by making
this change vs. the performance penalty due to the extra virtual
calls.

Chris Lattner 0046de17e5 Fix a couple of suboptimalities in error recovery.
1. In the top level of ParseStatementOrDeclaration, don't eat a } if we
   just parsed a statement if it list there.  Also, don't even bother
   emitting an error about a missing semicolon if the statement had a 
   bug (an rbrace is fine).
2. In do/while parsing, don't require a 'while' to be present if the do
   body didn't parse.

This allows us to generate a clean diagnostic for this code:

t.c:1:22: error: expected expression
void foo (void) { do . while (0); }
                     ^

Eli Friedman 8553a98b8e Backout of r59196, plus a new ICE test. Sorry if this is a
little rude; I figure it's cleaner to just back this out now so 
it doesn't get forgotten or mixed up with other checkins.

The modification to isICE is simply wrong; I've added a test that the 
change to isICE breaks.

I'm pretty sure the modification to tryEvaluate is also wrong.  
At the very least, there's some serious miscommunication going on here, 
as this is going in exactly the opposite direction of r59105.  My 
understanding is that tryEvaluate is not supposed to care about side 
effects.  That said, a lot of the clients to tryEvaluate are 
expecting it to enforce a no-side-effects policy, so we probably need 
another method that provides that guarantee.

Douglas Gregor b6acda0f36 Don't build identifiers for C++ constructors, destructors, or
conversion functions. Instead, we just use a placeholder identifier
for these (e.g., "<constructor>") and override NamedDecl::getName() to
provide a human-readable name.

This is one potential solution to the problem; another solution would
be to replace the use of IdentifierInfo* in NamedDecl with a different
class that deals with identifiers better. I'm also prototyping that to
see how it compares, but this commit is better than what we had
previously.

Douglas Gregor a11693bc37 Implement support for operator overloading using candidate operator
functions for built-in operators, e.g., the builtin

  bool operator==(int const*, int const*)

can be used for the expression "x1 == x2" given:

  struct X {
    operator int const*();
  } x1, x2;

The scheme for handling these built-in operators is relatively simple:
for each candidate required by the standard, create a special kind of
candidate function for the built-in. If overload resolution picks the
built-in operator, we perform the appropriate conversions on the
arguments and then let the normal built-in operator take care of it. 

There may be some optimization opportunity left: if we can reduce the
number of built-in operator overloads we generate, overload resolution
for these cases will go faster. However, one must be careful when
doing this: GCC generates too few operator overloads in our little
test program, and fails to compile it because none of the overloads it
generates match.

Note that we only support operator overload for non-member binary
operators at the moment. The other operators will follow.

As part of this change, ImplicitCastExpr can now be an lvalue.

Eli Friedman 9a156e5c1e Some additions to tryEvaluate I've had sitting around for a while.
This pushes it a lot closer to being able to deal with most of the stuff 
CodeGen's constant expression evaluator knows how to deal with.  This 
also fixes PR3003.

The test could possibly use some improvement, but this'll work for now.  
Test 6 is inspired by PR3003; the other tests are mostly just designed
to exercise the new code.  The reason for the funny structure of the 
tests is that type fixing for arrays inside of structs is the only place 
in Sema that calls tryEvaluate, at least for the moment.

 - This fixes a regression in emitting dummy blocks, notably for case
   statements.

 - This also fixes spurious emission of a number of debug stoppoint

Chris Lattner b7a9e16486 Make emission of 'if' conditions much more sophisticated when we
have a condition that is an &&/||.  Before we used to compile things like this:

int test() {
  if (x && y) foo(); else bar();
}

into:

	%0 = load i32* @x		; <i32> [#uses=1]
	%1 = icmp ne i32 %0, 0		; <i1> [#uses=1]
	br i1 %1, label %land_rhs, label %land_cont

land_rhs:		; preds = %entry
	%2 = load i32* @y		; <i32> [#uses=1]
	%3 = icmp ne i32 %2, 0		; <i1> [#uses=1]
	br label %land_cont

land_cont:		; preds = %land_rhs, %entry
	%4 = phi i1 [ false, %entry ], [ %3, %land_rhs ]		; <i1> [#uses=1]
	br i1 %4, label %ifthen, label %ifelse

ifthen:		; preds = %land_cont
	%call = call i32 (...)* @foo()		; <i32> [#uses=0]
	br label %ifend

ifelse:		; preds = %land_cont
	%call1 = call i32 (...)* @bar()		; <i32> [#uses=0]
	br label %ifend

ifend:		; preds = %ifelse, %ifthen


Now we turn it into the much more svelte code:

        %0 = load i32* @x               ; <i32> [#uses=1]
        %1 = icmp ne i32 %0, 0          ; <i1> [#uses=1]
        br i1 %1, label %land_lhs_true, label %ifelse

land_lhs_true:          ; preds = %entry
        %2 = load i32* @y               ; <i32> [#uses=1]
        %3 = icmp ne i32 %2, 0          ; <i1> [#uses=1]
        br i1 %3, label %ifthen, label %ifelse

ifthen:         ; preds = %land_lhs_true
        %call = call i32 (...)* @foo()          ; <i32> [#uses=0]
        br label %ifend

ifelse:         ; preds = %land_lhs_true, %entry
        %call1 = call i32 (...)* @bar()         ; <i32> [#uses=0]
        br label %ifend

ifend:          ; preds = %ifelse, %ifthen

Note the lack of a phi node.

Daniel Dunbar 5c7e3935f1 Rework IRgen invariant w.r.t. current insert point.
- EmitStmt is no longer required to finish with a current insertion
   point defined (i.e. it does not need to make dummy
   blocks). Instead, it can clear the insertion point in the builder
   which indicates that the current insertion point is unreachable.
 - CodeGenFunction provides HaveInsertPoint and EnsureInsertPoint
   which respectively test if there is an insert point and ensure an
   insertion point exists (by making a dummy block).
 - Clearly mark functions in CodeGenFunction which can be called with
   no insertion point defined. Currently this is a limited set, and
   EmitStmt simply EnsureInsertPoint()s before emitting subsequent IR.

Remove EmitDummyBlock, which is no longer needed. Clients who haven't
already cleared the insertion point (typically via EmitBranch) can do
so by hand.

Remove isDummyBlock, which has effectively been renamed to
HaveInsertPoint.

The main thrust of this change is that we no longer have create dummy
blocks just to destroy them a short time later in EmitBlock in the
common case that there is no unreachable code following something like
a goto. 

Additionally, this means that we are not using the hokey condition in
isDummyBlock that a block without a name is a dummy block. Guess how
well that works when we never emit block names!

Chris Lattner 5b1964b5f9 short circuit && and || when possible. This substantially reduces
the size of the -O0 output on some cases.  For example, on expr.c from
176.gcc, it shrinks the .ll file from 43164 to 42835 lines, and removed
references to two external symbols.

When allocating an array for ParamInfo, the "decl->getNumParams()" call was used, but this will return 0 since it checks ParamInfo (which isn't yet defined and is null).
