Andrew Lenharth 873ed82a36 FPSelect and more custom lowering
llvm-svn: 24535
2005-11-30 16:10:29 +00:00
Nate Begeman 1064d6ec43 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
}

Andrew Lenharth 6db615df14 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 :)

Reid Spencer 3fd1b4c9bf 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.

this to be something sane, but in the mean time it is unused, so safe to

Andrew Lenharth 93e59f6032 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.

Nate Begeman d37c13154a Check in code to scalarize arbitrarily wide packed types for some simple
vector operations (load, add, sub, mul).

This allows us to codegen:
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
}

on ppc as:
_foo:
        lfs f0, 12(r3)
        lfs f1, 8(r3)
        lfs f2, 4(r3)
        lfs f3, 0(r3)
        fadds f0, f0, f0
        fadds f1, f1, f1
        fadds f2, f2, f2
        fadds f3, f3, f3
        stfs f0, 12(r3)
        stfs f1, 8(r3)

llvm-svn: 24483
2005-11-22 04:20:06 +00:00
Nate Begeman 07890bbec4 Rather than attempting to legalize 1 x float, make sure the SD ISel never
generates it.  Make MVT::Vector expand-only, and remove the code in
Legalize that attempts to legalize it.

The plan for supporting N x Type is to continually epxand it in ExpandOp
until it gets down to 2 x Type, where it will be scalarized into a pair of
scalars.

  %tmp2 = add <1 x float> %tmp1, %tmp1
  store <1 x float> %tmp2, <1 x float> *%a

        lis r2, ha16(L_H$non_lazy_ptr)

on Darwin to remove smarts from the isel.  This is currently disabled by
default (uncomment setOperationAction(ISD::GlobalAddress to enable it).
tblgen needs to become smarter about tglobaladdr nodes and bigger patterns
needed to be added to the .td file.  However, we can currently emit stuff like
this:  :)

        li r2, lo16(L_x$non_lazy_ptr)
        lis r3, ha16(L_x$non_lazy_ptr)
        lwzx r2, r3, r2
