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 a nasty bug in LegalizeTypes (spotted in
...
CodeGen/PowerPC/illegal-element-type.ll): suppose
a node X is processed, and processing maps it to
a node Y. Then X continues to exist in the DAG,
but with no users. While processing some other
node, a new node may be created that happens to
be equal to X, and thus X will be reused rather
than a truly new node. This can cause X to
"magically reappear", and since it is in the
Processed state in will not be reprocessed, so
at the end of type legalization the illegal node
X can still be present. The solution is to replace
X with Y whenever X gets resurrected like this.

Change the lowering of arguments for tail call optimized
...
calls. Before arguments that could overwrite each other were
explicitly lowered to a stack slot, not giving the register allocator
a chance to optimize. Now a sequence of copyto/copyfrom virtual
registers ensures that arguments are loaded in (virtual) registers
before they are lowered to the stack slot (and might overwrite each
other). Also parameter stack slots are marked mutable for
(potentially) tail calling functions.
