Duncan Sands dc2dac181a If the type legalizer actually legalized anything
(this doesn't happen that often, since most code
does not use illegal types) then follow it by a
DAG combiner run that is allowed to generate
illegal operations but not illegal types.  I didn't
modify the target combiner code to distinguish like
this between illegal operations and illegal types,
so it will not produce illegal operations as well
as not producing illegal types.

Zhongxing Xu 9165ed69af Add support for AllocaRegion extent with GDM.
One design problem that is emerging is the signed-ness problem during static
analysis. Many unsigned value have to be converted into signed value because
it partipates in operations with signed values. 

On the other hand, we cannot blindly make all values occuring in static analysis
signed, because we do have cases where unsignedness is required, for example,
integer overflow detection.

Chris Lattner 1e5665e6be Change a whole lot of diagnostics to take QualType's directly
instead of converting them to strings first.  This also fixes a
bunch of minor inconsistencies in the diagnostics emitted by clang
and adds a bunch of FIXME's to DiagnosticKinds.def.

Chris Lattner f3d3faeca6 Rename NamedDecl::getName() to getNameAsString(). Replace a bunch of
uses of getName() with uses of getDeclName().  This upgrades a bunch of
diags to take DeclNames instead of std::strings.

This also tweaks a couple of diagnostics to be cleaner and changes
CheckInitializerTypes/PerformInitializationByConstructor to pass
around DeclarationNames instead of std::strings.

Nick Lewycky d59572cb22 Seriously strengthen the guarantee offered by noalias on a function's return
value. It must now be as if the pointer were allocated and has not escaped to
the caller. Thanks to Dan Gohman for pointing out the error in the original
and helping devise this definition.

Chris Lattner 86d7d91366 Rename NamedDecl::getIdentifierName() to ::getNameAsCString() and make it
assert if the name is not an identifier.  Update callers to do the right
thing and avoid this method in unsafe cases.  This also fixes an objc
warning that was missing a space, and migrates a couple more to taking
IdentifierInfo and QualTypes instead of std::strings.

Nick Lewycky f5ffcbcd0b Extend the 'noalias' attribute to function return values. This is intended to
indicate functions that allocate, such as operator new, or list::insert. The
actual definition is slightly less strict (for now).

No changes to the bitcode reader/writer, asm printer or verifier were needed.

Chris Lattner e4b95698df Rename Selector::getName() to Selector::getAsString(), and add
a new NamedDecl::getAsString() method.

Change uses of Selector::getName() to just pass in a Selector 
where possible (e.g. to diagnostics) instead of going through
an std::string.

This also adds new formatters for objcinstance and objcclass
as described in the dox.

Chris Lattner 4fc69799f5 Rewrite FindDiagnostics to be more strict about the formatting of the
expected-foo strings.  Now the only allowed characters between 
expected-error and {{  is whitespace.

Chris Lattner f3ab014308 clean up -verify mode output. If the expected-error string is
mangled, report it using the diagnostics machinery instead of printf.

Chris Lattner e6447ef989 make some objc redefinition warnings more consistent: call definitions
"definitions", not declarations.  Point out the location of the 
original definition.

Chris Lattner 88dcd2a1ab Tweak duplicate category diagnostic to work like the duplicate protocol diagnostic.
Also, point out where the previous decl was.  This unxfails two tests.

Chris Lattner e3d20d9545 Convert IdentifierInfo's to be printed the same as DeclarationNames
with implicit quotes around them.  This has a bunch of follow-on 
effects and requires tweaking to a whole lot of code.  This causes
a regression in two tests (xfailed) by causing it to emit things like:

  Line 10: duplicate interface declaration for category 'MyClass1' ('Category1')

instead of:

  Line 10: duplicate interface declaration for category 'MyClass1(Category1)'

I will fix this in a follow-up commit.

As part of this, I had to start switching stuff to use ->getDeclName() instead
of Decl::getName() for consistency.  This is good, but I was planning to do this
as an independent patch.  There will be several follow-on patches
to clean up some of the mess, but this patch is already too big.

llvm-svn: 59917
2008-11-23 21:45:46 +00:00
Chris Lattner f7e69d5a77 add support for inserting a DeclarationName into a diagnostic directly
without calling getAsString().  This implicitly puts quotes around the
name, so diagnostics need to be tweaked to accommodate this.

Chris Lattner 6a2ed6f6dc Add support for sending QualType's directly into diags and convert two
diags over to use this.  QualTypes implicitly print single quotes around 
them for uniformity and future extension.

Doing this requires a little function pointer dance to prevent libbasic
from depending on libast.
