/* Define auxiliary asm macros.
|
|
|
|
|
|
|
|
1) umul_ppmm(high_prod, low_prod, multipler, multiplicand) multiplies two
|
|
|
|
UWtype integers MULTIPLER and MULTIPLICAND, and generates a two UWtype
|
|
|
|
word product in HIGH_PROD and LOW_PROD.
|
|
|
|
|
|
|
|
2) __umulsidi3(a,b) multiplies two UWtype integers A and B, and returns a
|
|
|
|
UDWtype product. This is just a variant of umul_ppmm.
|
|
|
|
|
|
|
|
3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
|
|
|
|
denominator) divides a UDWtype, composed by the UWtype 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 in the UWtype X. This is the number of
|
|
|
|
steps X needs to be shifted left to set the msb. Undefined for X == 0,
|
|
|
|
unless the symbol COUNT_LEADING_ZEROS_0 is defined to some value.
|
|
|
|
|
|
|
|
6) count_trailing_zeros(count, x) like count_leading_zeros, but counts
|
|
|
|
from the least significant end.
|
|
|
|
|
|
|
|
7) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
|
|
|
|
high_addend_2, low_addend_2) adds two UWtype 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.
|
|
|
|
|
|
|
|
8) sub_ddmmss(high_difference, low_difference, high_minuend, low_minuend,
|
|
|
|
high_subtrahend, low_subtrahend) subtracts two two-word UWtype 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. */

* malloc/malloc.c (_malloc_internal): Performance fix. Move
if statement out of loop.

* malloc/malloc.c (_malloc_internal): Performance fix. Move
if statement out of loop.
* stdio/_itoa.c, stdio/_itoa.h: Complete rewrite. Much faster
implementation using GMP functions. Contributed by
Torbjorn Granlund and Ulrich Drepper.
