Subject: [PATCH] hwf-x86: fix use of wrong operand type
|
||||
|
||||
* src/hwf-x86.c (get_cpuid): Use xchg for swapping %ebx back
|
||||
and forth between operand register.
|
||||
--
|
||||
|
||||
HW feature routine was giving wrong results with certain compiler &
|
||||
compiler flag combinations on i386. Issue was that "=g" operand was
|
||||
used which caused problem if compiler allocated %ebx register for
|
||||
this operand. CPUID assembly block attempts to save %ebx as in older
|
||||
GCC versions this register was fixed for GOT pointer use and could
|
||||
not be modified otherwise (could not be used as operand or clobber).
