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no longer valid ("linux" is an OS, not an arch); instead we use a bogus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

pointer of MultiKeywordSelectors.
Added optimization to the serialization of SelectorTable where we only serialize
out MultiKeywordSelectors that are ever referenced by an object other than the
SelectorTable.

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.

that are referenced in the ASTs. This assumes that we serialize out the
decls/stmts first, and use the pointer-tracking logic in the Serializer to
determine if an IdentifierInfo (or its string key) is ever referenced.
This is a significant space optimization for serialized ASTs.
Consider the following program:
void foo(int x,int y) {
return x > y ? x : y+1;
}
Here are the sizes of the files for the serialized ASTs:
Full IdentifierTable: 23676 bytes
Only-referenced Identifiers: 304 bytes.
For this simple program, this is a 77% reduction in the file size of the
serialized ASTs.

and Materialize/Read instead of using specializations of SerializeTrait<>. The
resulting code is much cleaner. We are also setting the stage so that only the
parts of the IdentifierTable that are ever referenced within the ASTs are
serialized, and not the whole table.
llvm-svn: 43904
updated it to the recently updated Serialization API.
Changed clients of SourceLocation serialization to call the
appropriate new methods.
Updated Decl serialization code to put new skeleton serialization code
in place that is much better than the older trait-specialization
approach.
llvm-svn: 43625
Disabled assignments for ContentCache.
Copy-ctor for ContentCache now has an assertion preventing it to
be copied from an object that already has an allocated buffer.

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

bottleneck for -E computation, because every token that starts a line needs
to determine *which* line it is on (so -E mode can insert the appropriate
vertical whitespace). This optimization improves this common case where
it is striding through the line # table.
This speeds up -E on xalancbmk by 3.2%
