I've added the result to the demangler test suite, but I know of

not-really-checked demangled version is acceptable.
Unfortunately this patch broke GCC bootstrap.
cp-demangle.c isn't used just in libiberty, where using hashtab,
xcalloc, XNEW etc. is fine, but also in libsupc++/libstdc++, where
none of that is fine. That is why cp-demangle.c only uses e.g. realloc,
checks for allocation failures and propagates those to the caller
if they happen (see allocation_failure field). hashtab.o isn't linked
into libstdc++ nor libsupc++, and the question is if we really do want to
link all the hashtable code into libstdc++.
How many hash table entries are there typically? Is a hashtable required?
This is now bootstrap/58386. IMHO we should for the time being revert
the patch, the required modifications don't seem trivial.
Thanks,
Paolo.
