/* We need a special version of the `mcount' function since for ix86 it
Packit Service 82fcde
   must not clobber any register.  This has several reasons:
Packit Service 82fcde
     - there is a bug in gcc as of version 2.7.2.2 which prohibits the
Packit Service 82fcde
       use of profiling together with nested functions
Packit Service 82fcde
     - the ELF `fixup' function uses GCC's regparm feature
Packit Service 82fcde
     - some (future) systems might want to pass parameters in registers.  */
