/* The macros defined here use the timestamp counter in i586 and up versions
of the x86 processors. They provide a very accurate way to measure the
time with very little overhead. The time values themself have no real
meaning, only differences are interesting.
This version is for the i686 processors. The difference to the i586
version is that the timerstamp register is unconditionally used. This is
not the case for the i586 version where we have to perform runtime test
whether the processor really has this capability. We have to make this
distinction since the sysdeps/i386/i586 code is supposed to work on all
platforms while the i686 already contains i686-specific code.
The list of macros we need includes the following:
- HP_TIMING_AVAIL: test for availability.
- HP_TIMING_INLINE: this macro is non-zero if the functionality is not
implemented using function calls but instead uses some inlined code
which might simply consist of a few assembler instructions. We have to
