+dnl  Usage: ASSERT([reg] [,code])
+dnl
+dnl  Require that the given reg is non-zero after executing the test code.
+dnl  For example,
+dnl
+dnl         ASSERT(r8,
+dnl         `       cmpult r16, r17, r8')
+dnl
+dnl  If the register argument is empty then nothing is tested, the code is
+dnl  just executed.  This can be used for setups required by later ASSERTs.
+dnl  If the code argument is omitted then the register is just tested, with
+dnl  no special setup code.
+
+define(ASSERT,
+m4_assert_numargs_range(1,2)
+m4_assert_defined(`WANT_ASSERT')
+`ifelse(WANT_ASSERT,1,
+`ifelse(`$2',,,`$2')
+ifelse(`$1',,,
+`      bne     $1, L(ASSERTok`'ASSERT_label_counter)
+       .long   0       C halt
+L(ASSERTok`'ASSERT_label_counter):
+define(`ASSERT_label_counter',eval(ASSERT_label_counter+1))
+')
+')')
+define(`ASSERT_label_counter',1)
+
+
+dnl  Usage: bigend(`code')
+dnl
+dnl  Emit the given code only for a big-endian system, like Unicos.  This
+dnl  can be used for instance for extra stuff needed by extwl.
+
+define(bigend,
+m4_assert_numargs(1)
+`ifdef(`HAVE_LIMB_BIG_ENDIAN',`$1',
+`ifdef(`HAVE_LIMB_LITTLE_ENDIAN',`',
+`m4_error(`Cannot assemble, unknown limb endianness')')')')
+
+
+dnl  Usage: bwx_available_p
+dnl
+dnl  Evaluate to 1 if the BWX byte memory instructions are available, or to
+dnl  0 if not.
+dnl
+dnl  Listing the chips which do have BWX means anything we haven't looked at
+dnl  will use safe non-BWX code.  The only targets without BWX currently are
+dnl  plain alpha (ie. ev4) and alphaev5.
+
+define(bwx_available_p,
+m4_assert_numargs(-1)
+`m4_ifdef_anyof_p(
+       `HAVE_HOST_CPU_alphaev56',
+       `HAVE_HOST_CPU_alphapca56',

+       `HAVE_HOST_CPU_alphaev6',

+       `HAVE_HOST_CPU_alphaev69',
+       `HAVE_HOST_CPU_alphaev7',
+       `HAVE_HOST_CPU_alphaev79')')
+
+
+dnl  Usage: unop
+dnl
+dnl  The Cray Unicos assembler lacks unop, so give the equivalent ldq_u
+dnl  explicitly.
+
+define(unop,
+m4_assert_numargs(-1)
+`ldq_u r31, 0(r30)')
