16 years agoImplemented initial support for "-triple" option to the clang driver. This
Ted Kremenek [Mon, 3 Dec 2007 22:06:55 +0000 (22:06 +0000)]
Implemented initial support for "-triple" option to the clang driver. This
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  no longer valid ("linux" is an OS, not an arch); instead we use a bogus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.

Ted Kremenek [Thu, 29 Nov 2007 23:05:17 +0000 (23:05 +0000)]
Added method "HandleTopLevelDeclaration" to ASTConsumer. This will eventually
be the new hook that ASTStreamer calls to feed top-level Decls to
ASTConsumers.

The difference between "HandleTopLevelDeclaration" and "HandleTopLevelDecl" is
that "HandleTopLevelDecl" is currently called by ASTStreamer for every
top-level declaration, including those that appear within a Decl chain. Using
the new interface, ASTStreamer would only call HandleTopLevelDeclaration for
Decls that appear that the beginning of a Decl chain (i.e., a group of related
decls).

To preserve the behavior that all subclasses of ASTConsumer currently expect,
the default implementation of HandleTopLevelDeclaration simply calls
HandleTopLevelDecl, and for decl chains it calls HandleTopLevelDecl for each
Decl* in a chain of Decls.

The advantage of this interface is that some subclasses of ASTConsumer only
really want the Decl chain, and not each individual Decl passed to them. This
extra level of indirection allows subclasses to override the default behavior
if they so desire.

Added "isExact" field to FloatingLiteral.  This flag indicates whether or not
the APFloat representing the parsed literal can represent the literal value
exactly.  This is useful when performing various semantic checks on the code,
and issuing appropriate warnings to users.

Removed potential buffer overrun (spotted by Neil Booth) when NumericLiteralParser
converts a parsed literal into an APFloat. We are still performing a copy of the
string, which hopefully will be removed eventually for performance reasons. This
version now is at least safe.

Changed rounding in APFloat construction in NumericLiteralParser from rmTowardsZero
to rmNearestTiesToEven.

Several fixes/simplifications surrounding how we stream top-level decl AST's.

The following code...

typedef struct cssm_data {} CSSM_DATA, *CSSM_DATA_PTR;

struct Y { int A; };

struct X { int A; } D;

struct X E, F;

Read top-level tag decl: 'cssm_data'

Read top-level tag decl: 'X'
Read top-level variable decl: 'D'

Converted AST Pretty-Printer to use iostreams instead of FILE*.  This fixes
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.

(1) Parsed ASTs are pretty-printed to a text file.

(3) The ASTs are deserialized from disk.

"Output/stmt_exprs.c.out" and "Output/stmt_exprs.c.out.script" being created, the
files "Output/Sema/stmt_exprs.c.out" and "Output/Sema/stmt_exprs.c.out.script" are
created. This prevents any collisions from different test directories that have the
same file name for a test case, and also makes it clear where the test case was
drawn from.
