Jim Laskey 66c502b54a Running with frame pointers prevented debugging, external probes and 
potentially some system calls/exception handling from working.  TOS must always
link to previous frame.  This is a short term workaround until alloca scheme is
reworked.

Chris Lattner c5102bfc7c allow the offset of a preinc'd load to be the low-part of a global. This 
produces this clever code:

_millisecs:
        lis r2, ha16(_Time.1182)
        lwzu r3, lo16(_Time.1182)(r2)
        lwz r2, 4(r2)
        addic r4, r2, 1
        addze r3, r3
        blr

instead of this:

_millisecs:
        lis r2, ha16(_Time.1182)
        la r3, lo16(_Time.1182)(r2)
        lwz r2, lo16(_Time.1182)(r2)
        lwz r3, 4(r3)
        addic r4, r3, 1
        addze r3, r2
        blr

for:

long %millisecs() {
        %tmp = load long* %Time.1182            ; <long> [#uses=1]
        %tmp1 = add long %tmp, 1                ; <long> [#uses=1]
        ret long %tmp1
}

Chris Lattner 2ff632c54b Mark operands as symbol lo instead of imm32 so that they print lo(x) around 
globals.

Devang Patel db789fb8f2 Implement PassManagerImpl_New::add(). 
Just add pass into the pass manager queue without processing analysis.

llvm-svn: 31670
 2006-11-11 02:06:21 +00:00
Devang Patel 90b05e0bc3 While adding pass into the manager, process Analysis only if it is 
required to do so.

Reid Spencer 279a3aefc3 Enable path completion when typing the TESTSUITE= option by allowing the 
test directory to precede the test suite name. That is, it will strip off
test/ from TESTSUITE which allows path completion from the command line.

Chris Lattner a0a8003f59 disallow preinc of a frameindex. This is not profitable and causes 2-addr 
pass to explode.  This fixes a bunch of llc-beta failures on ppc last night.

Devang Patel 6c9f548704 Keep track of analysis required by the passes. Force use of new pass 
manager if a pass does not preserve analysis that is used by other
passes.

Evan Cheng 49683ba236 Don't dag combine floating point select to max and min intrinsics. Those 
take v4f32 / v2f64 operands and may end up causing larger spills / restores.
Added X86 specific nodes X86ISD::FMAX, X86ISD::FMIN instead.

This fixes PR996.

Evan Cheng fb44822a98 Fix a bug in SelectScalarSSELoad. Since the load is wrapped in a 
SCALAR_TO_VECTOR, even if the hasOneUse() check pass we may end up folding
the load into two instructions. Make sure we check the SCALAR_TO_VECTOR
has only one use as well.

Chris Lattner ce6455489a add an initial cut at preinc loads for ppc32. This is broken for ppc64 
(because the 64-bit reg target versions aren't implemented yet), doesn't
support r+r addr modes, and doesn't handle stores, but it works otherwise. :)

This is disabled unless -enable-ppc-preinc is passed to llc for now.
