Steve Naroff cdee44c12a Fixed Sema::CheckEqualityOperands() and Sema::CheckRelationalOperands() to deal more 
thoughtfully with incompatible pointers. This includes:

- Emit a diagnostic when two pointers aren't compatible!
- Promote one of the pointers/integers so we maintain the invariant expected by the 
code generator (i.e. that the left/right types match).
- Upgrade the pointer/integer comparison diagnostic to include the types.

Ted Kremenek e68f1aad65 Added support for additional format string checking for the printf 
family of functions.  Previous functionality only included checking to
see if the format string was a string literal.  Now we check parse the
format string (if it is a literal) and perform the following checks:

(1) Warn if: number conversions (e.g. "%d") != number data arguments.

(2) Warn about missing format strings  (e.g., "printf()").

(3) Warn if the format string is not a string literal.

(4) Warn about the use se of '%n' conversion.  This conversion is
    discouraged for security reasons.

(5) Warn about malformed conversions.  For example '%;', '%v'; these
    are not valid.

(6) Warn about empty format strings; e.g. printf("").  Although these
    can be optimized away by the compiler, they can be indicative of
    broken programmer logic.  We may need to add additional support to
    see when such cases occur within macro expansion to avoid false
    positives.

(7) Warn if the string literal is wide; e.g. L"%d".

(8) Warn if we detect a '\0' character WITHIN the format string.

Test cases are included.

Chris Lattner b87b1b36ee initial support for checking format strings, patch by Ted Kremenek: 
"I've coded up some support in clang to flag warnings for non-constant format strings used in calls to printf-like functions (all the functions listed in "man fprintf").  Non-constant format strings are a source of many security exploits in C/C++ programs, and I believe are currently detected by gcc using the flag -Wformat-nonliteral."

Steve Naroff 0104731e62 Restrict vector component access (using "." and "[]") to variables. 
Chris suggested this, since it simplifies the code generator.

Steve Naroff 236becbbc3 Two typeof() related changes... 
- Changed the name of ASTContext::getTypeOfType(Expr*)->getTypeOfExpr().
- Remove FIXME for TypeOfExpr::getAsStringInternal(). This will work fine for printing the AST. It isn't ideal
for error diagnostics (since it's more natural to display the expressions type). 

One "random" (or at least delayed:-) change...

- Changed all "ext_typecheck_*" diagnostics from EXTENSION->WARNING. Reason: Since -pedantic is now
off (by default), these diagnostics were never being emitted (which is bad). With this change, clang will
emit the warning all the time. The only downside (wrt GCC compatibility) is -pedantic-errors will not turn
this diagnostics into errors (a "feature" of making tagging them with EXTENSION). When/if this becomes
an issue, we can revisit.

Chris Lattner 02c0439a44 Fix a couple of bugs, add some new cool stuff. 
1. Fix a todo in Parser::ParseTag, to recover better.  On code like
   that in test/Sema/decl-invalid.c it causes us to return a single
   error instead of multiple.
2. Fix an error in Sema::ParseDeclarator, where it would crash if the
   declarator didn't have an identifier.  Instead, diagnose the problem.
3. Start adding infrastructure to track the range of locations covered
   by a declspec or declarator.  This is mostly implemented for declspec,
   but could be improved, it is missing for declarator.

Thanks to Neil for pointing out this crash.

Steve Naroff 44fd8ff400 Fix Sema::ParseCallExpr()...it wasn't doing the default array/function promotions on it's argument types. 
This resulted in the following errors when compiling promote_types_in_proto.c test...

[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang test/Parser/promote_types_in_proto.c 
test/Parser/promote_types_in_proto.c:7:24: error: incompatible types passing 'char *[]' to function expecting 'char *const []'
        arrayPromotion(argv);
        ~~~~~~~~~~~~~~ ^~~~
test/Parser/promote_types_in_proto.c:8:27: error: incompatible types passing 'void (char *const [])' to function expecting 'void (char *const [])'
        functionPromotion(arrayPromotion);
        ~~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~~~
2 diagnostics generated.

When fixing this, noticed that both ParseCallExpr() and ParseReturnStmt() were prematurely comparing types for
equivalence. This is incorrect (since the expr. promotions haven't been done yet). To fix this, I moved the
check "down" to Sema::CheckAssignmentConstraints().

I also converted Type::isArrayType() to the modern API (since I needed it). Still more Type predicates to 
convert.

Chris Lattner 43eafb4ed5 implement a missing feature in the #include handler, where 
it did not handle <xyz> headers coming from macro expansions.
This requires special treatment, as the include name is lexed
as multiple tokens, which require reassembly before processing.

Chris Lattner a6f5ab5425 Fix off-by-one error when emitting diagnostics. Also, make diagnostic 
a bit nicer for people who pass lots of extra arguments to calls by 
selecting them all instead of just the first one:

arg-duplicate.c:13:13: error: too many arguments to function
  f3 (1, 1, 2, 3, 4);   // expected-error {{too many arguments to function}}

out this crash.

Chris Lattner 3940737edf Two fixes: 
1) fix a crash on test/Sema/default.c by making
   sure that the switch scope is non-null.
2) if there is an error sema'ing a default or case stmt,
   make sure to return the substmt up, so that the error
   recovery code has more acurate info to continue with.

llvm-svn: 40134
 2007-07-21 03:00:26 +00:00
Chris Lattner 24dbee71ab Fix a stringizing bug that Neil noticed. We should preprocess this:

Steve Naroff fbd098332c Work towards fixing crasher with compound literals... 
Before this commit, we crashed in ParseBinOp...

[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang -parse-ast-check compound_literal.c
SemaExpr.cpp:1298: failed assertion `(rhs != 0) && "ParseBinOp(): missing right expression"'

With this commit, we still crash in the newly added action ParseCompoundLiteral (which is progress:-)

[dylan:~/llvm/tools/clang] admin% ../../Debug/bin/clang -parse-ast-check compound_literal.c
SemaExpr.cpp:478: failed assertion `(Op != 0) && "ParseCompoundLiteral(): missing expression"'

The crash go away once the actions return AST nodes. I will do this in a separate commit.

Bill Wendling dfc810717e Fix references:

 2007-07-16 23:25:18 +00:00
Chris Lattner bb1b44f004 Make octal constant lexing use AdvanceToTokenCharacter to give more 
accurate diagnostics.  For test/Lexer/comments.c we now emit:

int x = 000000080;  /* expected-error {{invalid digit}} */
               ^
constants.c:7:4: error: invalid digit '8' in octal constant
00080;             /* expected-error {{invalid digit}} */
   ^


The last line is due to an escaped newline.  The full line looks like:

int y = 0000\
00080;             /* expected-error {{invalid digit}} */


Previously, we emitted:
constants.c:4:9: error: invalid digit '8' in octal constant
int x = 000000080;  /* expected-error {{invalid digit}} */
        ^
constants.c:6:9: error: invalid digit '8' in octal constant
int y = 0000\
        ^

which isn't too bad, but the new way is better for the user,
regardless of whether there is an escaped newline or not.

All the other lexer-related diagnostics should switch over 
to using AdvanceToTokenCharacter where appropriate.  Help
wanted :).

This implements test/Lexer/constants.c.

Implement isIntegerConstantExpr for ImplicitCastExpr nodes the same

Implement proper sign/zero extension as well as truncation and noop
conversion in the i-c-e evaluator.  This allows us to correctly
handle i-c-e's like these:

char array[1024/(sizeof (long))];
int x['\xBb' == (char) 187 ? 1: -1];
