intrinsics that don't take pointer arguments now work. For example, we can
compile this:
int test3( __m128d *A) {
return _mm_movemask_pd(*A);
}
int test4( __m128 *A) {
return _mm_movemask_ps(*A);
}
to this:
_test3:
movl 4(%esp), %eax
movapd (%eax), %xmm0
movmskpd %xmm0, %eax
ret
_test4:
movl 4(%esp), %eax
movaps (%eax), %xmm0
movmskps %xmm0, %eax
ret

1. Check for Perl and only build llvm-config if its available.
2. Add some virtual components
3. Don't depend on "standard" location for Perl, but configured location
4. Document the tool with a POD file.
This version is now ready for testing by users.

next patch. For now, it just runs nm and greps each .o or .a file for
the desired symbol.

1. LLVMCBackend.o now depends on LLVMCodeGen.o (why we're not sure)
2. LLVMExecutionEngine.o no longer depends on LLVMInterpreter.o nor LLVMJIT.o

is a handy tool for users of LLVM who want to be able to quickly get
information about LLVM's configuration. It is intended to be used in the
command line of other tools. Documentation will be forthcoming in a
subsequent patch.

text enclosed in <tt>. This ensures that (a) the text is in a fixed width
font (to indicated generated text) and (b) the text wraps without causing
the page width to be extended. The main result of this is that the report
will wrap to conform to the window size in which it is displayed instead of
having a very wide length if a warning message is long.

The instruction patterns do not contain enough information to resolve the
exact type of the destination if it of a generic vector type.

makefile using the utils/GenLibDeps.pl script with the -flat option. It
records the dependencies between libraries in such a way that the
llvm-config script can easily read it (in makefile dependency format).

determine the top directory. This allows the tool to find the correct top
directory when you have something like:
/x/llvm
/x/llvm2
/x/llvm3
Previously the scripts would always find /x/llvm even if you were in the
llvm2 or llvm3 directory because the pattern didn't allow the digits at
the end of the path.

missing some cases due to ordering issue.

TableGen knows N1 must have more than one operand.

compilation, C++ compilation, and linker options.
e.g. This is the options I use for testing on my x86 iMac:
nice ./NightlyTest.pl -release -cflags "-Os -DNDEBUG -fomit-frame-pointer" -cxxflags "-Os -DNDEBUG -finline-functions -felide-constructors -fomit-frame-pointer"

us to avoid creating lots of "Operand" types with different printers, instead
we can fold several together and use modifiers. For example, we can now use:
${target:call} to say that the operand should be printed like a 'call' operand.

due to ordering issue. i.e. they were selected for chain use first.
Now at load select time, check if it is being selected for a chain use and if
it has only a single real use. If so, return a HANDLENODE (with the load as
its operand) in its place and record it.
When it is folded or the load is selected for a real use, the isel records it
as the replacement for the HANDLENODE. The replacement is done when all nodes
are selected.
This scheme exposed a couple of problems where cycles can happen. (See comments
in EmitMatchCode() for descriptions of the problems and their workaround /
solutions.) These problems have been resolved with a small compile time
penality.

X86 backend attempts to match small-immediate versions of instructions before
the full size immediate versions.

Chain is initially set to the chain operand of store node, when it reaches
load, if it matches the load then Chain is set to the chain operand of the
load.
However, if the matching code that follows this fails, isel moves on to the
next pattern but it does not restore Chain to the chain operand of the store.
So when it tries to match the next store / op / load pattern it would fail on
the Chain == load.getOperand(0) test.
The solution is for each chain operand to get a unique name. e.g. Chain10.

"if" statements (indenting it appropriately, of course) instead of using goto's.
This inverts the logic for all of the if statements, which makes things simpler
to understand in addition to making the generated code easier to read.

directly to the output file. This makes things simple because the code doesn't
have to worry about indentation or the case when there is no goto. It also
allows us to indent the code better without touching everything :)
