/* Macros for taking apart, interpreting and processing file names.
 
These are here because some non-Posix (a.k.a. DOSish) systems have
drive letter brain-damage at the beginning of an absolute file name,
use forward- and back-slash in path names interchangeably, and
some of them have case-insensitive file names.

/* This package implements basic hash table functionality. It is possible
to search for an entry, create an entry and destroy an entry.
 
Elements in the table are generic pointers.
 
The size of the table is not fixed; if the occupancy of the table
grows too high the hash table will be expanded.
 
The abstract data implementation is based on generalized Algorithm D
from Knuth's book "The art of computer programming". Hash table is
expanded by creation of new hash table and transferring elements from
the old table to the new table. */

/* Define auxiliary asm macros.
 
1) umul_ppmm(high_prod, low_prod, multiplier, multiplicand) multiplies two
UWtype integers MULTIPLIER 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. */
