we want to run just the instance of testclass-testmethod combination and nothing else.

Specifying '-g' now will admit the whole .py test module if it does not contain a matching
testclass-testmethod combination at all.

This option arrangement adheres to the RISC principle of making the common cases fast. :-)

rdar://problem/8584914 Can the default for dotest.py's "-g" flag be switched?

and "/private/tmp/a.c". This was done by adding a "mutable bool m_is_resolved;"
member to FileSpec and then modifying the equal operator to check if the
filenames are equal, and if they are, then check the directories. If they are
not equal, then both paths are checked to see if they have been resolved. If
they have been resolved, we resolve the paths in temporary FileSpec objects
and set each of the m_is_resolved bools to try (for lhs and rhs) if the paths
match what is contained in the path. This allows us to do more intelligent
compares without having to resolve all paths found in the debug info (which
can quickly get costly if the files are on remote NFS mounts).

Original patch for OpenBSD by Vladimir Kirillov.

llvm-svn: 118386

abstractions (e.g., TemplateArgumentListBuilder) that were designed to
support variadic templates. Only a few remnants of variadic templates
remain, in the parser (parsing template type parameter packs), AST
(template type parameter pack bits and TemplateArgument::Pack), and
Sema; these are expected to be used in a future implementation of
variadic templates.

But don't get too excited about that happening now.

where the DWARF is in the .o files so they can track down the actual type for
a forward declaration. This was working before for just DWARF files, but not
for DWARF in .o files where the actual definition was in another .o file.

Modified the main thread name in the driver to be more consistent with the
other LLDB thread names.

*) Try to detect as much as possible from the system itself, not the distro.
   This should make it easier to port to a new distro and more likely to
   work on a unknown one.
*) The distro enum now doesn't include the arch. Just use the existing
   host detection support in LLVM.
*) Correctly handle --sysroot.

A small regression is that now clang will pass bitcode file to the linker.
This is necessary for the gold plugin support to work.

It might be better to detect this at configure/cmake time, but doing it in
c++ first is a lot easier.

If so, that can be used as the value of the comparison.

This is really slow with we have 1000s of sections each with a corresponding
relocation section. Also, it is only used by the ELF writer to add
basic data, so there is no need to force a new layout pass.

the registers, because the register numbers may be much greater than the number
of bits available in the machine's register.

I extracted the register list verification code out of the actual parsing of the
registers. This made checking for errors much easier. It also limits the number
of warnings that would be emitted for cascading infractions.

exposed:

GAS doesn't accept "fcomip %st(1)", it requires "fcomip %st(1), %st(0)"
even though st(0) is implicit in all other fp stack instructions.

Fortunately, there is an alias for fcomip named "fcompi" and gas does
accept the default argument for the alias (boggle!).

As such, switch the canonical form of this instruction to "pi" instead
of "ip".  This makes the code generator and disassembler generate pi,
avoiding the gas bug.

shift-by-1 instructions, where the asmstring doesn't contain
the implicit 1.  It turns out that a bunch of these rotate
instructions were completely broken because they used 1 
instead of $1.

This fixes assembly mismatches on "rclb	$1, %bl" and friends,
where we used to generate the 3 byte form, we now generate the
proper 2-byte form.
