8fb3f3f682 Remove 'register' keyword. 2002-03-21 18:49:23 +00:00

d095bc220d Fix some bugs that would prevent %fsr to be set correctly, and add
support for fcmp and fcmpe instructions with a condition code
specification other than %fcc0.
This (primarily the first part) seems to fix a lot of problems that
people were seeing, e.g. perl and gawk failures.

57f31f4714 Fix __dtoul to work on sparc64 (it used a half-way v8 stack layout),
and make it PIC-aware.

9300cb7db7 Save/restore the %y register around calls to the C user trap handler;
gcc emits the deprecated sparc v8 instructions that use this register
when optimizing for UltraSparc machines because they are apparetly
faster then their v9 counterpars there.

f496405572 Fix a bug where siglongjmp would clobber the argument to return from
sigsetjmp.  It would return the value of the signal flag, instead.

4895e965c3 Add userland floating point emulator code for sparc64. This is a port
of the (never committed) in-kernel version (with some optimizations and
cleanups), which in turn was ported from NetBSD.

d1497824f0 Add space for %fsr and %tstate to utrapframe. Save them in the generic
user trap entry code.  Restore %asi and %ccr from the saved %tstate before
returning to the trapping user code.

fd8e4ebc8c o Move NTOHL() and associated macros into <sys/param.h>. These are
deprecated in favor of the POSIX-defined lowercase variants.
o Change all occurrences of NTOHL() and associated marcros in the
  source tree to use the lowercase function variants.
o Add missing license bits to sparc64's <machine/endian.h>.
  Approved by: jake
o Clean up <machine/endian.h> files.
o Remove unused __uint16_swap_uint32() from i386's <machine/endian.h>.
o Remove prototypes for non-existent bswapXX() functions.
o Include <machine/endian.h> in <arpa/inet.h> to define the
  POSIX-required ntohl() family of functions.
o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>,
  and <sys/param.h>.
o Prepend underscores to the ntohl() family to help deal with
  complexities associated with having MD (asm and inline) versions, and
  having to prevent exposure of these functions in other headers that
  happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
  third-party software forgetting to include an appropriate header.
o Remove some now unneeded pollution from <sys/types.h>.
o Add missing <arpa/inet.h> includes in userland.

Tested on:	alpha, i386

6ce4e876a7 Add libc side of user trap handling.
Add support for handling floating point disabled traps mostly in userland
for the simple single threaded case.  Not yet enabled by default.
Implement __sparc_utrap_install as specified by the sparc abi.
