/* 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 nonzero 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. */

* If not, I'll be glad to provide one.
*
* FEATURES
* - careful adherence to specs regarding flags, field width and precision;
* - good performance for large string handling (large format, large
* argument or large paddings). Performance is similar to system's sprintf
* and in several cases significantly better (make sure you compile with
* optimizations turned on, tell the compiler the code is strict ANSI
* if necessary to give it more freedom for optimizations);
* - return value semantics per ISO/IEC 9899:1999 ("ISO C99");
* - written in standard ISO/ANSI C - requires an ANSI C compiler.
*
* SUPPORTED CONVERSION SPECIFIERS AND DATA TYPES
*
* This snprintf only supports the following conversion specifiers:
* s, c, d, u, o, x, X, p (and synonyms: i, D, U, O - see below)
* with flags: '-', '+', ' ', '0' and '#'.
* An asterisk is supported for field width as well as precision.
*
* Length modifiers 'h' (short int), 'l' (long int),
* and 'll' (long long int) are supported.
* NOTE:
* If macro SNPRINTF_LONGLONG_SUPPORT is not defined (default) the
* length modifier 'll' is recognized but treated the same as 'l',
* which may cause argument value truncation! Defining
* SNPRINTF_LONGLONG_SUPPORT requires that your system's sprintf also
* handles length modifier 'll'. long long int is a language extension
* which may not be portable.
*
* Conversion of numeric data (conversion specifiers d, u, o, x, X, p)
* with length modifiers (none or h, l, ll) is left to the system routine
* sprintf, but all handling of flags, field width and precision as well as
* c and s conversions is done very carefully by this portable routine.
* If a string precision (truncation) is specified (e.g. %.8s) it is
* guaranteed the string beyond the specified precision will not be referenced.
*
* Length modifiers h, l and ll are ignored for c and s conversions (data
* types wint_t and wchar_t are not supported).
*
* The following common synonyms for conversion characters are supported:
* - i is a synonym for d
* - D is a synonym for ld, explicit length modifiers are ignored
* - U is a synonym for lu, explicit length modifiers are ignored
* - O is a synonym for lo, explicit length modifiers are ignored
* The D, O and U conversion characters are nonstandard, they are supported
* for backward compatibility only, and should not be used for new code.
*
* The following is specifically NOT supported:
* - flag ' (thousands' grouping character) is recognized but ignored
* - numeric conversion specifiers: f, e, E, g, G and synonym F,
* as well as the new a and A conversion specifiers
* - length modifier 'L' (long double) and 'q' (quad - use 'll' instead)
* - wide character/string conversions: lc, ls, and nonstandard
* synonyms C and S
* - writeback of converted string length: conversion character n
* - the n$ specification for direct reference to n-th argument
* - locales
*
* It is permitted for str_m to be zero, and it is permitted to specify NULL
* pointer for resulting string argument if str_m is zero (as per ISO C99).
*
* The return value is the number of characters which would be generated
* for the given input, excluding the trailing null. If this value
* is greater or equal to str_m, not all characters from the result
* have been stored in str, output bytes beyond the (str_m-1) -th character
* are discarded. If str_m is greater than zero it is guaranteed
* the resulting string will be null-terminated.
*
* NOTE that this matches the ISO C99, OpenBSD, and GNU C library 2.1,
* but is different from some older and vendor implementations,
* and is also different from XPG, XSH5, SUSv2 specifications.
* For historical discussion on changes in the semantics and standards
* of snprintf see printf(3) man page in the Linux programmers manual.
*
* Routines asprintf and vasprintf return a pointer (in the ptr argument)
* to a buffer sufficiently large to hold the resulting string. This pointer
* should be passed to free(3) to release the allocated storage when it is
* no longer needed. If sufficient space cannot be allocated, these functions
* will return -1 and set ptr to be a NULL pointer. These two routines are a
* GNU C library extensions (glibc).
*
* Routines asnprintf and vasnprintf are similar to asprintf and vasprintf,
* yet, like snprintf and vsnprintf counterparts, will write at most str_m-1
* characters into the allocated output string, the last character in the
* allocated buffer then gets the terminating null. If the formatted string
* length (the return value) is greater than or equal to the str_m argument,
* the resulting string was truncated and some of the formatted characters
* were discarded. These routines present a handy way to limit the amount
* of allocated memory to some sane value.

*
* REVISION HISTORY
* 1999-04 V0.9 Mark Martinec
* - initial version, some modifications after comparing printf
* man pages for Digital Unix 4.0, Solaris 2.6 and HPUX 10,
* and checking how Perl handles sprintf (differently!);
* 1999-04-09 V1.0 Mark Martinec <mark.martinec@ijs.si>
* - added main test program, fixed remaining inconsistencies,
* added optional (long long int) support;
* 1999-04-12 V1.1 Mark Martinec <mark.martinec@ijs.si>
* - support the 'p' conversion (pointer to void);
* - if a string precision is specified
* make sure the string beyond the specified precision
* will not be referenced (e.g. by strlen);
* 1999-04-13 V1.2 Mark Martinec <mark.martinec@ijs.si>
* - support synonyms %D=%ld, %U=%lu, %O=%lo;
* - speed up the case of long format string with few conversions;
* 1999-06-30 V1.3 Mark Martinec <mark.martinec@ijs.si>
* - fixed runaway loop (eventually crashing when str_l wraps
* beyond 2^31) while copying format string without
* conversion specifiers to a buffer that is too short
* (thanks to Edwin Young <edwiny@autonomy.com> for
* spotting the problem);
* - added macros PORTABLE_SNPRINTF_VERSION_(MAJOR|MINOR)
* to snprintf.h
* 2000-02-14 V2.0 (never released) Mark Martinec <mark.martinec@ijs.si>
* - relaxed license terms: The Artistic License now applies.
* You may still apply the GNU GENERAL PUBLIC LICENSE
* as was distributed with previous versions, if you prefer;
* - changed REVISION HISTORY dates to use ISO 8601 date format;
* - added vsnprintf (patch also independently proposed by
* Caolan McNamara 2000-05-04, and Keith M Willenson 2000-06-01)
* 2000-06-27 V2.1 Mark Martinec <mark.martinec@ijs.si>
* - removed POSIX check for str_m<1; value 0 for str_m is
* allowed by ISO C99 (and GNU C library 2.1) - (pointed out
* on 2000-05-04 by Caolan McNamara, caolan@ csn dot ul dot ie).
* Besides relaxed license this change in standards adherence
* is the main reason to bump up the major version number;
* - added nonstandard routines asnprintf, vasnprintf, asprintf,
* vasprintf that dynamically allocate storage for the
* resulting string; these routines are not compiled by default,
* see comments where NEED_V?ASN?PRINTF macros are defined;
* - autoconf contributed by Caolan McNamara
* 2000-10-06 V2.2 Mark Martinec <mark.martinec@ijs.si>
* - BUG FIX: the %c conversion used a temporary variable
* that was no longer in scope when referenced,
* possibly causing incorrect resulting character;
* - BUG FIX: make precision and minimal field width unsigned
* to handle huge values (2^31 <= n < 2^32) correctly;
* also be more careful in the use of signed/unsigned/size_t
* internal variables - probably more careful than many
* vendor implementations, but there may still be a case
* where huge values of str_m, precision or minimal field
* could cause incorrect behaviour;
* - use separate variables for signed/unsigned arguments,
* and for short/int, long, and long long argument lengths
* to avoid possible incompatibilities on certain
* computer architectures. Also use separate variable
* arg_sign to hold sign of a numeric argument,
* to make code more transparent;
* - some fiddling with zero padding and "0x" to make it
* Linux compatible;
* - systematically use macros fast_memcpy and fast_memset
* instead of case-by-case hand optimization; determine some
* breakeven string lengths for different architectures;
* - terminology change: 'format' -> 'conversion specifier',
* 'C9x' -> 'ISO/IEC 9899:1999 ("ISO C99")',
* 'alternative form' -> 'alternate form',
* 'data type modifier' -> 'length modifier';
* - several comments rephrased and new ones added;
* - make compiler not complain about 'credits' defined but
* not used;

*/

* is defined to expand to 'portable_v?snprintf' - see file snprintf.h .
* Defining this macro is only useful if HAVE_SNPRINTF is also defined,
* but does does no harm if defined nevertheless.
*/
/* #define PREFER_PORTABLE_SNPRINTF */
/* Define SNPRINTF_LONGLONG_SUPPORT if you want to support
* data type (long long int) and length modifier 'll' (e.g. %lld).
* If undefined, 'll' is recognized but treated as a single 'l'.
*
* If the system's sprintf does not handle 'll'
* the SNPRINTF_LONGLONG_SUPPORT must not be defined!
*
* This is off by default as (long long int) is a language extension.
*/
/* #define SNPRINTF_LONGLONG_SUPPORT */
/* Define NEED_SNPRINTF_ONLY if you only need snprintf, and not vsnprintf.
* If NEED_SNPRINTF_ONLY is defined, the snprintf will be defined directly,
* otherwise both snprintf and vsnprintf routines will be defined
* and snprintf will be a simple wrapper around vsnprintf, at the expense
* of an extra procedure call.
*/
/* #define NEED_SNPRINTF_ONLY */
/* Define NEED_V?ASN?PRINTF macros if you need library extension
* routines asprintf, vasprintf, asnprintf, vasnprintf respectively,
* and your system library does not provide them. They are all small
* wrapper routines around portable_vsnprintf. Defining any of the four
* NEED_V?ASN?PRINTF macros automatically turns off NEED_SNPRINTF_ONLY
* and turns on PREFER_PORTABLE_SNPRINTF.
*
* Watch for name conflicts with the system library if these routines
* are already present there.
*
* NOTE: vasprintf and vasnprintf routines need va_copy() from stdarg.h, as
* specified by C99, to be able to traverse the same list of arguments twice.
* I don't know of any other standard and portable way of achieving the same.
* With some versions of gcc you may use __va_copy(). You might even get away
* with "ap2 = ap", in this case you must not call va_end(ap2) !
* #define va_copy(ap2,ap) ap2 = ap
*/
/* #define NEED_ASPRINTF */
/* #define NEED_ASNPRINTF */
/* #define NEED_VASPRINTF */
/* #define NEED_VASNPRINTF */
/* Define the following macros if desired:
* SOLARIS_COMPATIBLE, SOLARIS_BUG_COMPATIBLE,
* HPUX_COMPATIBLE, HPUX_BUG_COMPATIBLE, LINUX_COMPATIBLE,
* DIGITAL_UNIX_COMPATIBLE, DIGITAL_UNIX_BUG_COMPATIBLE,
* PERL_COMPATIBLE, PERL_BUG_COMPATIBLE,
*
* - For portable applications it is best not to rely on peculiarities
* of a given implementation so it may be best not to define any
* of the macros that select compatibility and to avoid features
* that vary among the systems.
*
* - Selecting compatibility with more than one operating system
* is not strictly forbidden but is not recommended.
*
* - 'x'_BUG_COMPATIBLE implies 'x'_COMPATIBLE .
*
* - 'x'_COMPATIBLE refers to (and enables) a behaviour that is
* documented in a sprintf man page on a given operating system
* and actually adhered to by the system's sprintf (but not on
* most other operating systems). It may also refer to and enable
* a behaviour that is declared 'undefined' or 'implementation specific'
* in the man page but a given implementation behaves predictably
* in a certain way.
*
* - 'x'_BUG_COMPATIBLE refers to (and enables) a behaviour of system's sprintf
* that contradicts the sprintf man page on the same operating system.
*
* - I do not claim that the 'x'_COMPATIBLE and 'x'_BUG_COMPATIBLE
* conditionals take into account all idiosyncrasies of a particular
* implementation, there may be other incompatibilities.
