0dfa8582c5 Make type explicit for egcs, from Erik Bertelsen in PR 5287. 
Dump the register qualifier while we're here, as suggested in the PR.

f766e521be In kcopy(), make sure we save and restore the old fault handler; kcopy() 
is called from uiomove(), which may be in the code path of servicing
a non-fatal page fault caused by a copyin() or copyout().

Originally suggested by Steve Woodford.

b3fa451227 Amiga uses the common m68k/sig_machdep.c now. Also moved its definition from 
the other 68k ports' files.${port} to arch/m68k/conf/files.m68k.

6f57e5c573 multiple include protect machine/limits.h, fixes pr 4473 (from Mika Nystrom) 1998-01-09 22:23:44 +00:00
is
5d5c1cd59e - avoid system stack underflow when calling sigreturn via trap #0 
- make sure all sigreturn error conditions are reported to the caller,
  instead of the place jumped to.
This is the bugfix part of pr 4628 by ITOH Yasufumi.
The performance optimization part will be handled seperately, after evaluating
its implications.
Testing on 68040 and removing the performance change from the proposed patch
by scottr. Half of the Amiga machdep.c change had to be done manually by me,
as the patchfile didn't apply cleanly.
XXX Yes, Amiga should be changed to use the common sig_machdep.c instead.
XXX Really soon now. I promise.
 1998-01-07 22:46:00 +00:00
is
d002f566b3 Support 68060 (and, for the Amiga, even 68040 buserr frames) in the sendsig() 
and, indirectly, sigreturn() functions.
XXX The Amiga should be switched to using sig_machdep.c instead.

4730a8cbec Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>: 
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
  supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
  by the way it's used).

The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.)  The __indr_reference
change was made for consistency.

2ee51585ba Add ftwotox emulation, by using the fscale emulation routine (preload 
destination register bit pattern with 1.0), which automatically provides
corner case handling.
Missing ftwotox emulation originally reported by Norman Mackenzie in PR 4237,
but he proposed a different implementation.

6ab3092b11 Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern. 
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.
