we default to "i386-apple-darwin". This is an interim solution.
Removed processing of "linux" triples from Targets.cpp, since we don't have
any sensical Linux target support (yet).
Cleaned up error processing of targets; added better diagnostics.

replaces the functionality previously provided by just "-arch" (which is still
supported but has different semantics).
The new behavior is as follows:
(1) If the user does not specify -triple:
(a) If no -arch options are specified, the target triple used is the host
triple (in llvm/Config/config.h).
(b) If one or more -arch's are specified (and no -triple), then there is
one triple for each -arch, where the specified arch is substituted
for the arch in the host triple. Example:
host triple = i686-apple-darwin9
command: clang -arch ppc -arch ppc64 ...
triples used: ppc-apple-darwin9 ppc64-apple-darwin9
(2) The user does specify a -triple (only one allowed):
(a) If no -arch options are specified, the triple specified by -triple
is used. E.g clang -triple i686-apple-darwin9
(b) If one or more -arch options are specified, then the triple specified
by -triple is used as the primary target, and the arch's specified
by -arch are used to create secondary targets. For example:
clang -triple i686-apple-darwin9 -arch ppc -arch ppc64
has the following targets:
i686-apple-darwin9 (primary target)
ppc-apple-darwin9
ppc64-apple-darwin9
Other changes related to the changes to the driver:
- TargetInfoImpl now includes the triple string.
- TargetInfo::getTargetTriple returns the triple for its primary target.
- test case test/Parser/portability.c has been updated because "-arch linux" is
no longer valid ("linux" is an OS, not an arch); instead we use a bogus
architecture "bogusW16W16" where WCharWidth=16 and WCharAlign=16.

rewriter emit this error if it fails to rewrite an @encode:
t.m:17:9: error: rewriter could not replace sub-expression due to macros
c = ENC(char *)[2] + 4;
^~~~~~~~~~~
... where ENC is: #define ENC @encode

that are builtin and those that are aren't. This is a bunch
of API refactoring that will make this possible, but there is
no functionality change yet.

both before and after serialization/deserialization. If the CFGs between the pre-
and post- serialized/deserialized ASTs differ, the serialization has failed.
llvm-svn: 44429
a bug where the statement pretty-printer used iostreams but the AST printer
did not. This was an issue when dumping ASTs to something other than stderr.
Updated SerializationTest to use the new iostreams interface for the AST printer.
llvm-svn: 44417
(1) Parsed ASTs are pretty-printed to a text file.
(2) The ASTs are serialized to disk.
(3) The ASTs are deserialized from disk.
(4) The deserialized ASTs are pretty-printed to a text file.
(5) The two pretty-printed files are compared. If they are different, the test
fails.
llvm-svn: 44411
which is now used (or subclasssed) by the ASTConsumers. This new class
stores a FILE* that is used for writing, instead of just hardwiring output
to stderr (it defaults to stderr if no FILE* is provided).
Modified CreateASTPrinter() to accept a FILE* for printing.
llvm-svn: 44377
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).
llvm-svn: 44125
- 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:-)
llvm-svn: 44015
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.

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.

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.

- Synthesize the funky cast for objc_msgSend(). For the basic case, it looks like...
((id (*)(id, SEL))(void *)objc_msgSend)(obj, sel);
The "void *" cast is needed to workaround a GCC "bandaid" (Chris says it has something to do with the inliner). Without the extra "void *" cast, we get spurious warnings/notes that look like...
xx.m:17: warning: function called through a non-compatible type
xx.m:17: note: if this code is reached, the program will abort
- Add prototypes for the ObjC functions we call, objc_msgSend/objc_getClass for now (don't depend on them being included).
llvm-svn: 43685
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
llvm-svn: 43572
I need to (finally) change the way Class/id/SEL/IMP are built-in...the current approach of doing it in the preprocessor is "broken". The other problem is Sema::GetObjcIdType/GetObjcSelType/GetObjcClassType, the hooks that initialize ASTContext lazily. These built-in types need to be done up front...
llvm-svn: 43557
Still to do:
- Chris will fix a bug in the rewriting engine for nested stmts. For example, the following:
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
tranlates to:
NSAutoreleasePool * pool = objc_msgSend(objc_msgSend(objc_getClass("NSAutoreleasePool"), sel_getUid("alloc")), sel_getUid("init"))utoreleasePool"), sel_getUid("alloc")) init];
...which is correct, except there is garbage after sel_getUid("init"). This is because the rewriter isn't updating the extent of the containing message expression.
- Do the crazy cast thang.

protocol meta-data (unlike what documentation says). 2) Include objc.h so,
we can compile the generated metadata with both gcc and clang.
llvm-svn: 43311
new split-header file configuration (Serialize.h and Deserialize.h)
now in place in the core LLVM repository.
Removed unneeded SerializeTrait specializations for enums in
TokenKinds.h
llvm-svn: 43306
we currently turn:
c = @encode(char *)[2] + 4;
into:
c = "foo"[2] + 4;
Right now the foo string is hard coded, but you can imagine a world
where it wouldn't be :)
llvm-svn: 43093
Silenced some VC++ warnings.
Had to rephrase a partial specialization of the IntrospectionTrait struct in SerializationTest.cpp, please review.
Added a compiler specific workaround in IdentifierTable.h. Is that the way to fix this kind of issues?
llvm-svn: 43074
serialization logic as well as driver code is now in
Driver/SerializationTest.cpp. The status of this code is that it
should be used by no clients.
Added --test-pickling option to driver to run the serialization code.
Modified IdentifierInfo and IdentifierTable to have friend classes
that permit object serialization. Such friendship may not be needed
in the final design.
