I think that's okay. However:
Do you have a prefix or not?
If there is no prefix, DECL_NAME (t) == NULL.
If there is a prefix, the name is create_tmp_var_name (prefix),
which is (on most systems) "%s.%d", prefix, tmp_var_id_num++
Otherwise, the D.1234 you see in the dump is mostly the result of
"D.%u", DECL_UID (t).
Yes, this clears up things. Thanks!
I am currently trying to figure out better ways of debugging
generated code (PR 90207) and one thing is to make intermediate
variables visible to the debugger, of course under control of
a special flag. The dot is of course not a good choice beause
gdb will not print a variable called S.0, but maybe a @ will work.
Or, less amitious, sometimes it is hard to see by which path a
certain variable is generated. Being able to set a breakpoint
where a certain variable is being generated can help a lot.
Best regards
Thomas
