Hi Olivier, > Sorry, I had -mapcs-frame in mind.
That's identical to -mapcs, and equally deprecated. It was superceded 2 decades ago. -mpcs-frame bugs have been reported multiple times, including on VxWorks. For example https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64379 suggests VxWorks doesn't need -mapcs-frame. And that was in 2014! So I think we need to push much harder on getting rid of obsolete stuff and avoid people encountering these nasty issues. Cheers, Wilco
