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:
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no longer valid ("linux" is an OS, not an arch); instead we use a bogus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.

Added getTrueExpr() and getFalseExpr() to ConditionalOperator. These methods
provide handy accessors to the subexpressions of ConditionalOperator that
automatically take into account the GCC extension where the "LHS" expression is
omitted: e.g x ?: y;. When the LHS expression is available, getTrueExpr() is the
same as getLHS(); when LHS is NULL, getTrueExpr() returns the condition expression.

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.
When generating the CodeGen type name of a struct, union, enum use the typedef
name if a tag type name is not available for the type. This matches how llvm-gcc
chooses CodeGen type names.
This means that "typedef struct {...} foo" now results in a CodeGen name of
"struct.foo" rather than "struct."

Yesterday, I simplified how we stream top-level decls.
After a discussion with Ted, we both came to the conclusion that adding a "HandleTopLevelDeclaration" hook to ASConsumer is far more elegant. The default implementation of HandleTopLevelDeclaration will be responsible for iterating over the ScopedDecl (which has a chain of the decls:-).
TODO: Once Ted adds HandleTopLevelDeclaration, make sure TagDecls are chainged appropriately...
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.

Enhanced implementation of -Wfloat-equal to check for comparisons against
floating-point literals that are represented exactly by the APFloat in
FloatingLiteral. For such literals, we do not emit a warning since such checks are
often performed in real code to see if a variable has changed from its original
value. This heuristic clearly can lead to false negatives, but the hope is it will
significantly reduce false positives to help make the compiler flag more useful.

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.
