Jim Laskey ebdf6f46eb Works for PowerPC with frame pointers. 
llvm-svn: 31679
 2006-11-11 10:22:56 +00:00
Reid Spencer 2e80be8251 Add -lstdc++ to the link line for C++ programs. 
llvm-svn: 31678
 2006-11-11 10:22:48 +00:00
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 1a6eaa49fe Implement schedulePasses(). 
llvm-svn: 31671
 2006-11-11 02:22:31 +00:00
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.

 2006-11-11 01:04:13 +00:00
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.

 2006-11-11 01:02:45 +00:00
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.

llvm-svn: 31661
 2006-11-11 01:00:15 +00:00

 2006-11-11 00:56:29 +00:00
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.

llvm-svn: 31659
 2006-11-11 00:42:16 +00:00
