Hi, I am trying to disable pass arguments by register in my project. I suppose -mregparm=0 can do this but unfortunately it doesn't work with -O3. The arguments are still through registers even I specified -mregparm=0.
I am not sure if this intentional or a bug? -mregparm is a specific option. In general the priority should be higher than -O3 which is a group option, right? Thanks, Wei
