Hi Iain,
If it’s part of a symbol used by the rest of the toolchain (assembler,
linker
debugger) then it’s also important to note that some OS/tool pairs might
be more constrained than the one you’ve tested. In particular, some
assemblers will not accept all characters in an identifier.
That is, of course, true. What I have works for the usual Linux
toolchain. Since I do not have access to other systems where
I can compile gcc (see the recent *BSD desaster when I tried this),
the most I could do is to make the character configurable - use
: by default, use something else if specified.
You could take advantage of the understanding of assembler identifier rules
built into create_var_debug_raw()
.. perhaps (totally untested)….
if (flag_debug_aux_vars)
prefix = prefix ? prefix : “gfc”;
t = create_tmp_var_raw (type, prefix);
if (flag_debug_aux_vars)
{
/* We want debug info for it. */
DECL_IGNORED_P (t) = false;
/* It should not be nameless. */
DECL_NAMELESS (t) = false;
}
return t;
… or doens’t this approach work for some reason?
This doesn't work for gdb because gdb searches for
a variable called "S" when trying to access "S.0".
I also tried out @ as a separation character; that
is also interpreted by gdb in a special way.
And I wanted to avoid anything in the namespace of
Fortran identifiers, even with options, so _ and $ were
out.
Do you have any other suggestions?
Best regards
Thomas
