demangler, java, clinit, $E

[mec dot gnu at mindspring dot com (Michael Elizabeth Chastain)]

I picked up 100,000 Java mangled names for the Eclipse project from Tom
Tromey.  I compared them with old versus new demangler.  This Eclipse is
x86, red hat linux 9, gcj 3.4 20031212.

There were 1052 differences.  All of them were like this:

  a-eclipse.list!460

    _ZN3com6redhat7eclipse3rpm13import_export8Messages18__U3c_clinit__U3e_Ev
    com::redhat::eclipse::rpm::import_export::Messages::<clinit>()
    com::redhat::eclipse::rpm::import_export::Messages::__U3c_clinit__U3e_()

'__U3c' and '__U3e' are Unicode encoding for '<' and '>'.

A quick look inside the source shows me that it's supposed to be this
way.

The old demangler did unicode decoding for '__U' all the time, but the
new demangler does it only if DMGL_JAVA is turned on.  So gdb will have
to be careful to turn on DMGL_JAVA when it needs to.

There are also 127 names which did not demangle at all, even with
"--format java".  This happens with both old and new demangler.
These worry me.  I have appended the list.
