While hunting for two hanging tests,
...
(on solaris10, which are:
CodeGen/PowerPC/frounds.ll
Transforms/InstCombine/2008-02-23-MulSub.ll)
I needed a tool to figure out which one is the guilty.
To this end I have added a verbosity
option to the test/Makefile.
It can be invoked thus:
gmake check TESTSUITE=CodeGen/PowerPC VERBOSE="-v -v"
(The number of "-v"s specifies the verbosity level.
Instead of "-v" other aliases can be specified,
please consult the dejagnu docs for info.)
At level >= 2 following line is logged for each
test, before running it:

Fix isNegatibleForFree to not return true for ConstantFP nodes
...
after legalize. Just because a constant is legal (e.g. 0.0 in SSE)
doesn't mean that its negated value is legal (-0.0). We could make
this stronger by checking to see if the negated constant is actually
legal post negation, but it doesn't seem like a big deal.

Merge current work back to tree to minimize diffs and drift. Major highlights

for CellSPU modifications:
- SPUInstrInfo.td refactoring: "multiclass" really is _your_ friend.
- Other improvements based on refactoring effort in SPUISelLowering.cpp,
esp. in SPUISelLowering::PerformDAGCombine(), where zero amount shifts and
rotates are now eliminiated, other scalar-to-vector-to-scalar silliness
is also eliminated.
- 64-bit operations are being implemented, _muldi3.c gcc runtime now
compiles and generates the right code. More work still needs to be done.
