--- Comment #10 from Ian Lance Taylor <ian at airs dot com> 2011-02-04 14:16:32 UTC --- What advantage do we bring to our users by requiring them to be aware of the details of the PIC register when writing inline asm code? Again, those who *are* aware of the PIC register have complete control. But many people are able to write assembler code but have no idea what the PIC register is. In what way are we helping them by forcing them to know about it? How does that help them write inline assembler which, e.g., uses the cpuid instruction, or makes a kernel system call which passes a parameter in %ebx?
