Mangle question

[Carlo Wood <carlo at alinoe dot com>]

Hiya,

I noticed that when in a mangled name a 'T' is used with an index larger
than 9, it is appended an underscore.  This seems to make no sense.
Why is this done?

When this works:

>c++filt f__1AiiiiiiiiRt3bar1ZfiT9cT9T9
A::f(int, int, int, int, int, int, int, int, bar<float> &, int, bar<float> &, char, bar<float> &, bar<float> &)

Then I'd think that f__1AiiiiiiiiRt3bar1ZfiT10cT10T10 is fine too,
but instead 'T10_' is used:

>c++filt f__1AiiiiiiiiiRt3bar1ZfiT10_cT10_T10_
A::f(int, int, int, int, int, int, int, int, int, bar<float> &, int, bar<float> &, char, bar<float> &, bar<float> &)

This is a mangled name as is returned by `nm', after compiling a program.
Also c++filt demands the '_' to be there though, if we remove the '_':

>c++filt f__1AiiiiiiiiiRt3bar1ZfiT10cT10T10
A::f(int, int, int, int, int, int, int, int, int, bar<float> &, int, int, , char, int, , int, )

I suppose it works as it works, but I still wonder why :)
Does anyone know?

PS If someone knows then as a bonus I'll report two bugs in the demangler ;)
