Update the cpu specified on some PPC regression tests Some of these tests did not specify a cpu but were also sensitive to instruction scheduling and/or register assignment choices. A few others similarly-sensitive tests specified a cpu (often the POWER7), and while the P7 currently uses the default model for PPC64, this will soon change. For those tests which should not really be cpu-dependent anyway, the cpu is set to the generic 'ppc64'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195977 91177308-0d34-0410-b5e6-96231b3b80d8

Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally. This update was done with the following bash script: find test/CodeGen -name "*.ll" | \ while read NAME; do echo "$NAME" if ! grep -q "^; *RUN: *llc.*debug" $NAME; then TEMP=`mktemp -t temp` cp $NAME $TEMP sed -n "s/^define [^@]*@\([A-Za-z0-9_]*\)(.*$/\1/p" < $NAME | \ while read FUNC; do sed -i '' "s/;\(.*\)\([A-Za-z0-9_-]*\):\( *\)$FUNC: *\$/;\1\2-LABEL:\3$FUNC:/g" $TEMP done sed -i '' "s/;\(.*\)-LABEL-LABEL:/;\1-LABEL:/" $TEMP sed -i '' "s/;\(.*\)-NEXT-LABEL:/;\1-NEXT:/" $TEMP sed -i '' "s/;\(.*\)-NOT-LABEL:/;\1-NOT:/" $TEMP sed -i '' "s/;\(.*\)-DAG-LABEL:/;\1-DAG:/" $TEMP mv $TEMP $NAME fi done git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@186280 91177308-0d34-0410-b5e6-96231b3b80d8

Remove the link register from the GPR classes on PowerPC. Some implementation detail in the forgotten past required the link register to be placed in the GPRC and G8RC register classes. This is just wrong on the face of it, and causes several extra intersection register classes to be generated. I found this was having evil effects on instruction scheduling, by causing the wrong register class to be consulted for register pressure decisions. No code generation changes are expected, other than some minor changes in instruction order. Seven tests in the test bucket required minor tweaks to adjust to the new normal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178114 91177308-0d34-0410-b5e6-96231b3b80d8
