block separate from ASTContext. This block is serialized out AFTER writing out
ASTContext, but deserialized BEFORE reading in ASTContext. This permits the
optimization of the serialization of the IdentifierTable where we only write
out identifiers that are used.

This was needed because TagDecls are owned by Types, and TagDecls contain
identifiers. Thus types need to be written out first to register with the
serializer any identifiers they refer to (and hence need to be serialized out
with IdentifierTable).

Fix yesterday's regression with rewriting @optional/@required.

llvm-svn: 44119

Rewrite methods that span multiple lines.

floating point comparisons using == or != an opt-in rather than a default
warning.

Updated test case to use -Wfloat-equal.

- Minor cleanup to yesterday's changes to Sema::ObjcActOnStartOfMethodDef();
- Add Sema::CurMethodDecl, in preparation for adding ObjcIvarRefExpr.
- Add ObjcInterfaceDecl::lookupInstanceVariable(), in prep for adding ivars.
- A couple renames in ObjcInterfaceDecl, while I was in the vicinity:-)

This is the last 5% of the solution to teaching Sema::ActOnInstanceMessage() about private methods (r43989).

While the diff is large, the idea is very simple. When we parse method definitions (in an @implementation), we need to add them incrementally (rather than wait until the @end).

Other details...

- Renamed Sema::ActOnAddMethodsToObjcDecl() to Sema::ActOnAtEnd(). The methods are now optional arguments.
- Removed Parser::AllImplMethods (a nice cleanup).
- Added location info to ObjcImplementationDecl (since we will need it very soon:-)
- Modified message.m test to no longer allow the bogus diagnostic.

(1) serialize out top-level decls BEFORE serializing out translation unit
structures like ASTContext.

(2) deserialize out translation unit structures like ASTContext before
top-level decls by first skipping the decls in the bitstream, deserializing
ASTContext and friends, and then jumping back to the bitstream block with the
decls and then deserializing them.

Change (1) allows us to utilize the pointer-tracking system in the Serializer
to only serialize out metadata that is actually referenced by the ASTS.

Change (2) allows us to deserialize the metadata first as before, which
signficantly reduces the amount of pointer backpatching the deserializer
would have to do if the decls were deserialized first.

Rewrite global variable initializers. 

llvm-svn: 43947

- add typedef guards.
- tweak scanForProtocolRefs heuristic.
- disable RewriteInclude() for now.

llvm-svn: 43942

Rewrite RewriteObjCStringLiteral(). This version is simpler (and unlike the previous one, works:-)

llvm-svn: 43890

llvm-svn: 43882

Disable rewrite-tabs.  This speeds up processing of the commentified huge
crazy testcase steve gave me from 20s to 6.6s in a release build.

llvm-svn: 43880

Finishing touches on code generation for @try and friends.

- declare functions we use.
- cast arguments to objc_exception_match().
- don't take the & of _stack.buf.

llvm-svn: 43831

llvm-svn: 43830

Implement rewrite for @throw.

llvm-svn: 43820

Rewrite ObjC @try/@catch/@finally. Some minor tweaks to the AST nodes...

Still need to rewrite @throw (and do more testing)...

llvm-svn: 43778

Revampled Serialization Tester to serialize and deserialize out an entire ASTContext and top-level decls.

llvm-svn: 43773

2) Fixed a regression in meta-data generation caused by removal of '_interface' prefix from synthesize class name.
3) Added stubs for @try/@catch/@finally statements.

llvm-svn: 43716

Declare objc_selector outside the prototype for objc_msgSend(), removing a silly warning.

llvm-svn: 43706

Rewrite @selector(sel).

llvm-svn: 43705

- change the synthesized typedef (for classes) to be of type "objc_object".
- fix a couple bugs in RewriteObjCStringLiteral.
- convert "Class" -> "id" in RewriteMessageExpr.
