114fb4cdb1 FPSelect and more custom lowering 
llvm-svn: 24535

31121419c8 First chunk of actually generating vector code for packed types. These 
changes allow us to generate the following code:

_foo:
        li r2, 0
        lvx v0, r2, r3
        vaddfp v0, v0, v0
        stvx v0, r2, r3
        blr

for this llvm:

void %foo(<4 x float>* %a) {
entry:
        %tmp1 = load <4 x float>* %a
        %tmp2 = add <4 x float> %tmp1, %tmp1
        store <4 x float> %tmp2, <4 x float>* %a
        ret void
}

dd3477b285 All sorts of stuff. 
Getting in on the custom lowering thing, yay
evilness with fp setcc, yuck
trivial int select, hmmm
in memory args for functions, yay
DIV and REM, always handy.  They should be custom lowered though.

Lots more stuff compiles now (go go single source!).  Of course, none of it
probably works, but that is what the nightly tester can find out :)

3bac59d2f0 Fix a problem with llvm-ranlib that (on some platforms) caused the archive 
file to become corrupted due to interactions between mmap'd memory segments
and file descriptors closing. The problem is completely avoiding by using
a third temporary file.

there is no fmul, it will have to do vmaddfp, adding +0.0.

2e375c1847 don't say this is i128, because it isn't yet. Hopefully nate will change 
this to be something sane, but in the mean time it is unused, so safe to
make something bogus.

311ec68cf4 Random sampling (aka Arnold and Ryder) profiling. This is still preliminary, but it works on spec on x86 and alpha. The idea is to allow profiling passes to remember what profiling they inserted, then a random sampling framework is inserted which consists of duplicated basic blocks (without profiling), such that at each backedge in the program and entry into every function, the framework chooses whether to use the instrumented code or the instrumentation free code. The goal of such a framework is to make it reasonably cheap to do random sampling of very expensive profiling products (such as load-value profiling). 
The code is organized into 3 parts (2 passes)
1) a linked set of profiling passes, which implement an analysis group (linked, like alias analysis are).  These insert profiling into the program, and remember what they inserted, so that at a later time they can be queried about any instruction.

2) a pass that handles inserting the random sampling framework.  This also has options to control how random samples are choosen.  Currently implemented are Global counters, register allocated global counters, and read cycle counter (see? there was a reason for it).

The profiling passes are almost identical to the existing ones (block, function, and null profiling is supported right now), and they are valid passes without the sampling framework (hence the existing passes can be unified with the new ones, not done yet).

Some things are a bit ugly still, but that should be fixed up soon enough.

Other todo? making the counter values not "magic 2^16 -1" values, but dynamically choosable.

687456dd7a Some first bits of AltiVec stuff: Instruction Formats, Encodings, and 
Registers.  Apologies to Jim if the scheduling info so far isn't accurate.

There's a few more things like VRsave support that need to be finished up
in my local tree before I can commit code that Does The Right Thing for
turning 4 x float into the various altivec packed float instructions.
