Hi!
I found very serious bug in very low level function: division of long
numbers in LDIVMODU macro (available at label __U4D), which used for Watcom,
is wrong. Example: try to divide 10_0000h/8_000fh. Remainder should be
7_FFF1h, but it is 0F_FFF1h. (This is because "divisor hi-word" in DI is
lost).
Tomorrow I present new ludivmul.inc edition. It will include:
- fix for bug;
- optimization (shorter code);
- (Lucho) 32-bit division code for 386-enabled kernel.
