program and fallback to plain version otherwise. Use this for the NetBSD
target to make it try e.g. i486--netbsdelf-as and -ld for target
i486--netbsdelf.

Drop program paths on NetBSD (unused). Only include lib dir, if
-nostdlib is absent. Use = to allow --sysroot to work.

prefix for -B.

code below it. Even though it looks very similar, it will match more precisely
and geneate better functions in the long run.

This is a helper class that will make it easier to say which InstAliases can be
printed and which cannot (because of ambiguity).

* Move the code that emits the reg in reg class matching into its own function.

the alias of an InstAlias instead of the thing being aliased. Because we need to
know the features that are valid for an InstAlias.

This is part of a work-in-progress.

As suggested by Nick Lewycky, ignore debugging intrinsics when trying to decide whether a destructor is empty or not.

as the addresses are now a lot closer.

if '-x' flag is present it will be unused.

Add an optimization to GlobalOpt that eliminates calls to __cxa_atexit, if the function passed is empty.

- glibc falls back to fork+exec if a file actions object is present.
- On BSDs this saves a malloc.

If a class inherits from RefCountedBaseVPTR allow all its subclasses to be used with IntrusiveRefCntPtr.

This can happen when multiple sibling registers are spilled after live range
splitting.

static archive that can be linked against. LLDB.framework/lldb.so
exports a very controlled API. Splitting the API into a static
library allows other tools (debugserver for now) to use the power
of the LLDB debugger core, yet not export it as its API is not
portable or maintainable. The Host layer and many of the other
internal only APIs can now be statically linked against.

Now LLDB.framework/lldb.so links against "liblldb-core.a" instead
of compiling the .o files only for the shared library. This fix
is only for compiling with Xcode as the Makefile based build already
does this.

The Xcode projecdt compiler has been changed to LLVM. Anyone using
Xcode 3 will need to manually change the compiler back to GCC 4.2,
or update to Xcode 4.

Downgrade err_mismatched_exception_spec to a ExtWarning in Microsoft mode. MSVC doesn't do any validation on exception specifications.

This remove 1 error when parsing MSVC stl lib with clang.
