Chris Lattner b8bd2db8b3 fix off-by-one error. 
llvm-svn: 44963

Ted Kremenek 1daa3cfbae TargetInfo no longer includes a reference to SourceManager. 
Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation.
Added many utility methods to FullSourceLoc to provide shorthand for:

    FullLoc.getManager().someMethod(FullLoc.getLocation());
    
instead we have:

    FullLoc.someMethod();
    
Modified TextDiagnostics (and related classes) to use this short-hand.

Ted Kremenek d4e5fbacab Mega-patch: ripped SourceManager out of Diagnostic/DiagnosticClient. Now 
SourceManager is passed by reference, allowing the SourceManager to be
associated with a specific translation unit, and not the entire execution
of the driver.

Modified all users of Diagnostics to comply with this new interface.

Integrated SourceManager as a member variable of TargetInfo. TargetInfo will
eventually be associated with a single translation unit (just like
SourceManager).

Made the SourceManager reference in ASTContext private. Provided accessor
getSourceManager() for clients to use instead. Modified clients to comply with
new interface.

Chris Lattner 11fbda2b5a Reimplement support for strings that initialize global inits now that 
the types are right in sema.  Thanks Steve.

 2007-12-11 01:38:45 +00:00
Chris Lattner 433fb26707 add support for implicit cast from array to pointer that is not the element 
type.

Chris Lattner cb04ac9599 abort when we lower an initializer to the wrong type, as we currently do for: 
char text[] = "string";

Chris Lattner 686628e052 extend or truncate the initializer for a string initializer to match its type.

Chris Lattner c25c42f3ca Implement codegen support for: 
char text[8] = "string";

Big fixme remains.

Chris Lattner 283d094b75 implement support for functions that initialize globals.

Christopher Lamb 0cbd8723f3 Treat discarding array initializer elements as an extwarn (so -pedantic-errors flags it). Allow CodeGen to truncate the initializer if needed.

Chris Lattner 5bcdf24a50 Handle global variable definitions which change the type of a definition, such as: 
extern int x[];
void foo() { x[0] = 1; }
int x[10];
void bar() { x[0] = 1; }

their prototype.

Chris Lattner c8dbe1e5d6 Warn about unsupported codegen with the diags machinery, giving us: 
t.c:3322:5: warning: cannot codegen this yet
    __asm__ ("bswap   %0" : "+r" (_data));
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Oliver Hunt aefc8fd415 Support initalisers for more than just int-typed static variables. 
We now use the CodeGenModule logic for generating the constant 
initialiser expression, so happily further initialiser fixes should 
automatically work for statics as well.

 2007-12-02 00:11:25 +00:00
Chris Lattner fb30009465 Implement support for -fwritable-strings and make the code generator 
merge string literals when it is not provided.

Chris Lattner 136449a6d7 improve codegen for global variable initializers, implementing

Devang Patel 75ef2f0b45 Take 2. 
Make target info available to clang code generator.  This is far from complete but this helps clang codegen module make progress.

At the moment target triplet and target description strings are hard coded in clang::TargetInfo
