/* You have to define the following before including this file:
UWtype -- An unsigned type, default type for operations (typically a "word")
UHWtype -- An unsigned type, at least half the size of UWtype.
UDWtype -- An unsigned type, at least twice as large a UWtype
W_TYPE_SIZE -- size in bits of UWtype
UQItype -- Unsigned 8 bit type.
SItype, USItype -- Signed and unsigned 32 bit types.
DItype, UDItype -- Signed and unsigned 64 bit types.
On a 32 bit machine UWtype should typically be USItype;
on a 64 bit machine, UWtype should typically be UDItype.

/* 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.
1995-02-18 01:27:10 +00:00
2) __umulsidi3(a,b) multiplies two UWtype integers A and B, and returns a
UDWtype product. This is just a variant of umul_ppmm.
1995-02-18 01:27:10 +00:00
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.
1995-02-18 01:27:10 +00:00
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,
1995-02-18 01:27:10 +00:00
and is lost.
If any of these macros are left undefined for a particular CPU,
C macros are used. */

New highly optimized string functions for i[345]86. * sysdeps/i386/memchr.S, sysdeps/i386/memcmp.S: New files. * sysdeps/i386/stpcpy.S, sysdeps/i386/stpncpy.S: New files. * sysdeps/i386/strchr.S, sysdeps/i386/strcspn.S: New files. * sysdeps/i386/strpbrk.S, sysdeps/i386/strrchr.S: New files. * sysdeps/i386/strspn.S, sysdeps/i386/i486/strcat.S: New files. * sysdeps/i386/i486/strlen.S, sysdeps/i386/i586/strchr.S: New files. * sysdeps/i386/i586/strlen.S: New file. * sysdeps/i386/memchr.c: Removed. There is now an assembler version. * sysdeps/i386/i586/memcopy.h (WORD_COPY_BWD): Parameters did not correspond to used values. * sysdeps/unix/sysv/linux/nfs/nfs.h: New file. Simply a wrapper around a kernel header file. * sysdeps/unix/sysv/linux/Dist: Add it. * sysdeps/unix/sysv/linux/Makefile [$(subdir)=sunrpc] (headers): Likewise. * sysdeps/unix/sysv/linux/local_lim.h: Rewrite. Instead of defining ourself we use a kernel header file. * sysdeps/unix/sysv/linux/i386/sysdep.h (DO_CALL): Optimize system call handler for i586. * sysdeps/unix/sysv/linux/sys/param.h: Add copyright and clean up.
