    33  dnl  ia64 assembler comments are C++ style "//" to the end of line.  gas
    34  dnl  also accepts "#" as a comment, if it's the first non-blank on a line.
    35  dnl
    36  dnl  BSD m4 can't handle a multi-character comment like "//" (see notes in
    37  dnl  mpn/asm-defs.m4).  For now the default "#" is left, but with care taken
    38  dnl  not to put any macros after "foo#" (since of course they won't expand).

    49  dnl  32-byte alignment is used for the benefit of itanium-2, where the code
    50  dnl  fetcher will only take 2 bundles from a 32-byte aligned target.  At
    51  dnl  16mod32 it only reads 1 in the first cycle.  This might not make any
    52  dnl  difference if the rotate buffers are full or there's other work holding
    53  dnl  up execution, but we use 32-bytes to give the best chance of peak
    54  dnl  throughput.
    55  dnl
    56  dnl  We can use .align here despite the gas bug noted in mpn/ia64/README,
    57  dnl  since we're not expecting to execute across a PROLOGUE(), at least not
    58  dnl  currently.

    85  dnl
    86  dnl  Emit a ".align" directive.  "bytes" is eval()ed, so can be an
    87  dnl  expression.
    88  dnl
    89  dnl  This version overrides the definition in mpn/asm-defs.m4.  We suppress
    90  dnl  any .align if the gas byte-swapped-nops bug was detected by configure
    91  dnl  GMP_ASM_IA64_ALIGN_OK.

   101  dnl
   102  dnl  Require that the given predicate register is true after executing the

   104  dnl
   105  dnl         ASSERT(p6,
   106  dnl         `       cmp.eq  p6,p0 = r3, r4')
   107  dnl
   108  dnl  If the predicate register argument is empty then nothing is tested, the
   109  dnl  code is just executed.  This can be used for setups required by later
   110  dnl  ASSERTs.  The code argument can be omitted to just test a predicate
   111  dnl  with no special setup code.
   112  dnl
   113  dnl  For convenience, stops are inserted before and after the code emitted.
