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_alphapca57',
`HAVE_HOST_CPU_alphaev6',
`HAVE_HOST_CPU_alphaev67',
`HAVE_HOST_CPU_alphaev68',
`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)')
