Hi all,
In TDebugInfoStabs.method_add_stabstr (unit dbgstabs) the following strings are added for parameter-types: '3var', '5const' and '3out'.
What do the numbers (3,5) before 'var', 'const' and 'out' mean?

'3var' in stabs-debuginfo. What does the 3 mean?

A little guess:
The length of the word following the number (e.g. 3var -> a 3 character string ('var') after it) - like String, but serialized. :P

:-) That's a pretty good guess - it actually makes sense.
That's why I wrote it :P

See http://sourceware.org/gdb/onlinedocs/stabs.html#Methods . Method names in stabs have to be mangled according to the algorithm described in "The Annotated C++ Reference Manual, by Ellis and Stroustrup, ISBN 0-201-51459-1". That algorithm includes prepending the length to all parameter names.
