scw 37b34d511d As discussed (briefly) on tech-userlevel, fix our quad support to work
correctly on LP64 platforms. This is mostly just s/long/int/ where
appropriate.

kleink ba7f64cc15 Revert previous change: the assertion
* is made in a utility function with file scope only, and
* will never fail.

lukem b48252f365 * use _DIAGASSERT() to check pointer arguments against NULL and file
descriptors against -1 (as appropriate).
* add actual checks which to detect stuff that would trigger_DIAGASSERT(),
  and attempt to return a sane error condition.
* knf some code
* remove some `register' decls.

the first two items result in the addition of code similar to the
following in various functions:

		_DIAGASSERT(path != NULL)
	#ifdef _DIAGNOSTIC
		if (path == NULL) {
			errno = EFAULT;
			return (-1);
		}
	#endif

drochner 24ca0bcfa6 The last commit changed the behavious wrt sign extension.
Back it out and replace with LINTED comments.

christos 314e0b18b9 change an #if __GNUC >= 2 to #if (__GNUC__ >= 2) || defined(lint)
to get the right definition of qshift_t.

christos 9ed746aaf1 Cast things to (digit) where the LHS is (digit) to avoid loss of precision
lint warnings. This change should be harmless.

christos 3314f1b0c5 Cast signed long shifts to unsigned long to avoid lint portability warnings.
The comment above the code mentions that it should work even on machines
that shift in zeroes.

mouse a9aceea509 Make shifting by 0 work even when shifting by 32 is equivalent to shifting
by 0.  Fixes lib/4845 (KNFification of the fix given therein).

cgd 1656c8d473 don't include lshrdi3.c in MI sources, since they're already in MD sources 1996-12-20 19:44:12 +00:00
jtc ae94fc4d74 Note functions that probably can be removed 1996-06-01 21:39:21 +00:00
jtc 8e1fdaa50e Don't special case shift counts > QUAD_BITS or == 0. The former is
undefined behavior (so we can do whatever we want) while the latter
doesn't happen much in actual practice.

These changes make these functions considerably smaller and faster.

jtc 17c5522d18 Re-arranged code a bit so that gcc can optimize this a bit better.
This change results in better code on the i386, m68k, & ns32k, and
equivalent code on the sparc.

jtc af8ead3302 Fix from Jochen Pohl which fixes case where quad multiply
goes awry if bit 31 of at least one of the operands is set
(PR #1591).
