+ dnl  .type is omitted and the mainline program references that function then
+ dnl  the code will be copied down to the mainline at load time like a piece
+ dnl  of data.  If .size is wrong or missing (it defaults to 4 bytes or some
+ dnl  such) then incorrect bytes will be copied and a segv is the most likely
+ dnl  result.  In any case such copying is not what's wanted, a .type
+ dnl  directive will ensure a PLT entry is used.
+ dnl
+ dnl  In GMP the assembler functions are normally only used from within the
+ dnl  library (since most programs are not interested in the low level

+ dnl  ------------------
+ dnl  Find out how to call mcount for profiling on an x86 system.
+ dnl
+ dnl  A dummy function is compiled and the ".s" output examined.  The pattern
+ dnl  matching might be a bit fragile, but should work at least with gcc on
+ dnl  sensible systems.  Certainly it's better than hard coding a table of
+ dnl  conventions.
+ dnl
+ dnl  For non-PIC, any ".data" is taken to mean a counter might be passed.
+ dnl  It's assumed a movl will set it up, and the right register is taken
+ dnl  from that movl.  Any movl involving %esp is ignored (a frame pointer
+ dnl  setup normally).
+ dnl
+ dnl  For PIC, any ".data" is similarly interpreted, but a GOTOFF identifies
+ dnl  the line setting up the right register.
+ dnl
+ dnl  In both cases a line with "mcount" identifies the call and that line is
+ dnl  used literally.
+ dnl
+ dnl  On some systems (eg. FreeBSD 3.5) gcc emits ".data" but doesn't use it,
+ dnl  so it's not an error to have .data but then not find a register.
+ dnl
+ dnl  Variations in mcount conventions on different x86 systems can be found
+ dnl  in gcc config/i386.  mcount can have a "_" prefix or be .mcount or
+ dnl  _mcount_ptr, and for PIC it can be called through a GOT entry, or via
+ dnl  the PLT.  If a pointer to a counter is required it's passed in %eax or
+ dnl  %edx.
+ dnl
+ dnl  Flags to specify PIC are taken from $lt_prog_compiler_pic set by
+ dnl  AC_PROG_LIBTOOL.
+ dnl
+ dnl  Enhancement: Cache the values determined here. But what's the right way
