KMSRCS is different from SRCS. Put __syscall.S in latter.
2000-12-13 07:05:55 +00:00
0e35eedd7e
Move __syscall.S to the arch specific Makefile.inc's where it is
...
implemented.

Adjust for changes in asm.h.

Add trivial implementation.

Handle __syscall() in user-level code for i386.
2000-12-10 21:27:37 +00:00

Use the SYSTRAP() macro more uniformly.
2000-12-08 22:57:57 +00:00

Use A1 to save the return address, since A0 is no longer preserved across
...
system calls.
2000-12-07 14:13:43 +00:00

The last change broke things if SYS___vfork14 returned an error; fix it.
2000-12-07 14:12:49 +00:00

The mapping is, effectively, an exclusive or with 0x01. Replace.
...
Savings: 10 bytes of code/constant data, 1 machine instruction (including
one memory access).
2000-12-04 12:02:08 +00:00
6751bb4f81
Save the return address in %a1 across the vfork syscall instead of %a0.
2000-12-02 17:03:06 +00:00
c586587e47
Restore %a0 after the call to sigprogmask(2) since an ELF kernel
...
will stomp on it due to SVR4 ABI compliance...

Another change by Hiroshi Horimoto.
2000-11-28 15:23:09 +00:00
c81e32f3dd
Add missing register prefixes.
2000-11-28 11:37:20 +00:00

Add a missing `%' register prefix.
2000-11-28 11:34:14 +00:00
a3a6f324e6
Use dbeq loops, code submitted by Hiroshi Horimoto in PR 3223, integrated
...
and tested by Allen Briggs.
Needs 1/3 less time on 68030, 45% less time on 68040.
XXX On 68060, 1/2 less time for the padding part, but 40% more time on the
copy part. I've stared at the 68060 User Manual, but can't understand why;
must be some wierd (branch) cache interaction.
2000-11-27 22:35:30 +00:00
5d73d71676
Fix modf() (I hope. Can't be any worse than the old version.)
2000-11-01 23:32:41 +00:00
4912e50a59
Make memcpy and memmove use bcopy assembly for mips. Tweak forward copy
...
code for backward copy to make overlap copy faster. This happens in
some SW like sleepycat db. Use temp labels in order to not confused
the profiling tools.
2000-10-10 21:51:54 +00:00

Whitespace botch in previous, noticed by Leo Weppelman and Thorsten Frueauf.

Move the Alpha _mcount() into a .S file so that it can be
...
pre-processed, like other Alpha assembly files.
2000-09-05 16:28:30 +00:00
d3312c2719
Fix layout of fields in jmp_buf. [N.B. we could make JMP_BUFLEN 9 if we want.]
2000-08-28 00:45:59 +00:00

add newline at end of file, to please (the quite buggy) mkid

%edx is free; use it instead of %ebx.

Change comment character from '#' to '!'. (binutils-2.10 doesn't like '#')
2000-08-04 08:47:03 +00:00

Need to reserve a full 64-bit stackframe, not a 32-bit one.
2000-07-26 00:53:50 +00:00
01a39929fc
Store the whole 64-bit pointer...
2000-07-25 20:15:40 +00:00

Use cpp comment style.
2000-07-25 15:14:45 +00:00
c54917029b
Make __dtoul() actually DTRT. The calling convention was totally wrong, and
...
the `big' value should be 2^63, not 2^31.
Also, nuke __fixunsdfsi(), since this is never output by the sparc64 compiler.
2000-07-25 04:26:12 +00:00
4272204d8d
Offset the %i2 stack slot from %sp, not %fp. Otherwise we may modify the
...
caller's registers!
2000-07-24 15:36:49 +00:00

There's no good reason not to assume a 64-bit stack here.
2000-07-24 15:24:55 +00:00

Don't bother saving %f16-%f31, since we don't use them.

e740400671
Just use a store/load pair to get the pattern into the FP reg. This eliminates
...
a bunch of cruft and avoids using a v9a instruction.
In addition, eliminate 8 of the fmovda's, which we are not using the result of
anyway.
Net result is that this should be faster in all cases.
2000-07-23 20:34:07 +00:00

Fix stack BIAS issues.

Revert previous change -- turned out I'd got my build environment in a twist.
2000-07-15 15:07:34 +00:00
985033a7a6
Add fixunssfsi and fixunsdfsi. These are provided by libgcc2.c in GCC 2.95,
...
but not in EGCS.
This version of fixunssfsi is almost exactly the arm32 version. fixunsdfsi is
mostly based on fixdfsi, but with simplifications for 64-bit integers.
Only minimal testing has been applied so far.
2000-07-15 13:26:50 +00:00

Block align pointer *AFTER* fixing up possible stack bias.

Add special treatment of shmat(2).
...
On m68k ELF calling standard (__SVR4_ABI__), if a function
returns a pointer, the return value should go to a0 as well as d0.
2000-07-07 08:20:50 +00:00

Missed in previous: replace the previously used _brk label with an ordinary

Fix a major botch in 1.4 (which I did not do) which broke _brk and malloc.
