anyone knows *all* the different ways that function names may be
mangled (for the linker)?
Probably only "svn blame/praise" combined with checking out old
versions of compiler/symdef.pas does.
I asked because this is sometime the only info returned by gdb (if
there is no debug info). And it could be useful to parse it.
It used to be Unit_class_$__function$...
SYSTEM_TOBJECT_$__DISPATCH$formal
but I also saw
CLASSES$_$TREADER_$__$$_READINTEGER$$LONGINT
makes me wonder if in some cases there may be more info between all
the $$ ?
No. That's a change that was made because e.g. unit1._class1 and
unit1_.class1 resulted in the same mangled name. "$" is not a valid
character in Pascal identifiers and hence was added as a separator in
the mangled name.
And also will need the format for plain functions (not methods)
You should not try to parse the mangled name, because FPC's name
mangling is a one-way process at this time (and always has been until
now). If the mangled name's length gets close to 250 characters, the
end will be replaced by a CRC of the name (possibly multiple times).
