Changes in directory llvm/lib/Target/PowerPC:
README.txt updated: 1.101 -> 1.102
---
Log message:
the code in question is now:
cmpw cr0, r7, r3
ble cr0, LBB1_5 ;bb25
LBB1_8: ;bb17
cmpw cr0, r8, r5
bgt cr0, LBB1_2 ;bb
which is just as good as crnand.

-PowerPC i1/setcc stuff (depends on subreg stuff):
-
-Check out the PPC code we get for 'compare' in this testcase:
-http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19672
-
-oof. on top of not doing the logical crnand instead of (mfcr, mfcr,
-invert, invert, or), we then have to compare it against zero instead of
-using the value already in a CR!
-
-that should be something like
- cmpw cr7, r8, r5
- cmpw cr0, r7, r3
- crnand cr0, cr0, cr7
- bne cr0, LBB_compare_4
-
-instead of
- cmpw cr7, r8, r5
- cmpw cr0, r7, r3
- mfcr r7, 1
- mcrf cr7, cr0
- mfcr r8, 1
- rlwinm r7, r7, 30, 31, 31
- rlwinm r8, r8, 30, 31, 31
- xori r7, r7, 1
- xori r8, r8, 1
- addi r2, r2, 1
- or r7, r8, r7
- cmpwi cr0, r7, 0
- bne cr0, LBB_compare_4 ; loopexit
-
FreeBench/mason has a basic block that looks like this:
%tmp.130 = seteq int %p.0__, 5 ; <bool> [#uses=1]
