/* Define auxiliary asm macros.
1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
multiplies two u32 integers MULTIPLER and MULTIPLICAND,
and generates a two-part u32 product in HIGH_PROD and
LOW_PROD.
2) __umulsidi3(a,b) multiplies two u32 integers A and B,
and returns a u64 product. This is just a variant of umul_ppmm.
3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
denominator) divides a two-word unsigned integer, composed by the
integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
places the quotient in QUOTIENT and the remainder in REMAINDER.
HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
If, in addition, the most significant bit of DENOMINATOR must be 1,
then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
denominator). Like udiv_qrnnd but the numbers are signed. The
quotient is rounded towards 0.
5) count_leading_zeros(count, x) counts the number of zero-bits from
the msb to the first non-zero bit. This is the number of steps X
needs to be shifted left to set the msb. Undefined for X == 0.
6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
high_addend_2, low_addend_2) adds two two-word unsigned integers,
composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
LOW_ADDEND_2 respectively. The result is placed in HIGH_SUM and
LOW_SUM. Overflow (i.e. carry out) is not stored anywhere, and is
lost.
7) sub_ddmmss(high_difference, low_difference, high_minuend,
low_minuend, high_subtrahend, low_subtrahend) subtracts two
two-word unsigned integers, composed by HIGH_MINUEND_1 and
LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
respectively. The result is placed in HIGH_DIFFERENCE and
LOW_DIFFERENCE. Overflow (i.e. carry out) is not stored anywhere,
and is lost.
If any of these macros are left undefined for a particular CPU,
C macros are used. */

* We used to clear some PSR bits here but that requires slow

* The rationale is as follows: we used to clear bits
* ~PSR_PRESERVED_BITS in PSR.L. Since
* PSR_PRESERVED_BITS==PSR.{UP,MFL,MFH,PK,DT,PP,SP,RT,IC}, we
* ended up clearing PSR.{BE,AC,I,DFL,DFH,DI,DB,SI,TB}.
* However,
*
* PSR.BE : already is turned off in __kernel_syscall_via_epc()
* PSR.AC : don't care (kernel normally turns PSR.AC on)
* PSR.I : already turned off by the time fsys_bubble_down gets
* invoked
* PSR.DFL: always 0 (kernel never turns it on)
* PSR.DFH: don't care --- kernel never touches f32-f127 on its own
* initiative
* PSR.DI : always 0 (kernel never turns it on)
* PSR.SI : always 0 (kernel never turns it on)
* PSR.DB : don't care --- kernel never enables kernel-level
* breakpoints
* PSR.TB : must be 0 already; if it wasn't zero on entry to
* __kernel_syscall_via_epc, the branch to fsys_bubble_down
* will trigger a taken branch; the taken-trap-handler then
* converts the syscall into a break-based system-call.
