Re: [MRISC32] Not getting scaled index addressing in loops

[m]

I'm sorry about the messed up code formatting (I blame the WYSIWYG). I 
hope the message gets through anyway (have a look at the Compiler 
Explorer link - https://godbolt.org/z/drzfjsxf7 - it has all the code).

This question seems off-topic on this mailing list, as it's not about GCC
development. It would be more suited to the gcc-help list.

I don't think you can do that. You need to use __VA_ARGS__ to accept
arbitrary code containing commas. You could look at how the
Boost.Preprocessor library works.

Hello,
  if I want to dump elements of gomp_places_list
in a string

gomp_affinity_print_place (gomp_places_list[i]);
what does this function do ?
I read its body, it has only one line
(void) p;
should I call it before sprintf (temp_buffer, );
