pk 63c8772a52 Do the `_REENTRANT' song-and-dance. 1996-11-16 20:43:07 +00:00
jtc f6f38dd61e Changed the test that determines whether or not source and destination
memory regions are "potentially overlapping" to a test that determines
that the regions are actually overlapping.  Because the code for the
overlapping case is seven instructions longer, this signifcantly
improves performance in the average case.

think of no good reason to be different.
1996-11-07 05:20:33 +00:00
jtc f1af62ef3d Changed so that when __REENTRANT is defined, cerror calls __errno()
for the address of a variable used to store the error number instead
of writing to the global errno.

In a multi-threaded program, __errno() will return a pointer to a
thread-specific variable.

jonathan a68c573b21 Rewrite from scratch. 1996-10-19 12:32:04 +00:00
jtc 41da409893 Added new macros:
SYSCALL_NOERROR(x):     Like SYSCALL except that "x" is a syscall
				that can never fail.

        RSYSCALL_NOERROR(x):    Like RSYSCALL except that "x" is a syscall
				that can never fail.

These macros simply call SYSCALL / RSYSCALL, and serve as placeholders
until an optimized implementation is done.
1996-10-19 00:25:22 +00:00
jtc 41056da8a0 Include <machine/asm.h> instead of defining our own ENTRY() macro
Changed all instances of ENTRY() to match the new calling convention
(it takes a second argument ).

Added new macros:
	SYSTRAP(x):		Expands to the code used to call syscall x.
				This is used to simplify other macros.

	SYSCALL_NOERROR(x):	Like SYSCALL except that "x" is a syscall
				that can never fail.

	RSYSCALL_NOERROR(x):	Like RSYSCALL except that "x" is a syscall
				that can never fail.

cgd 7b8ed4c70b update for new <machine/asm.h> and generally clean up:

cgd 572e3f3188 don't forget inifinity.c 1995-02-25 16:24:22 +00:00
cgd ea1ca14ecb need these for new gen/Makefile 1995-02-25 16:20:12 +00:00
cgd 6929ad87a5 need these now, with new net Makefile.inc 1995-02-25 14:58:43 +00:00
cgd 3f45f31f15 strange corner cases:
(1) zero top 32 bits for 32-bit unsigned ops; 32-bit value can
		be accidentally(?) sign-extended by the compiler/assembler.
	(2) fix return value for mod's that cause traps

jtc e7d917e6eb Remove extra "u" constraint that caused gcc 2.6.3 not to compile this file.
Note that gcc 2.4.5, the compiler we are currently using, still compiles it
correctly after this change.

cgd e4f5181d15 libc support for the alpha. more functions should be written in assembler,
but that's optimization.  8-)
