4cc90c99f2 The last change broke things if SYS___vfork14 returned an error; fix it. 2000-12-07 14:12:49 +00:00
is
0bffee4893 The mapping is, effectively, an exclusive or with 0x01. Replace. 
Savings: 10 bytes of code/constant data, 1 machine instruction (including
one memory access).

6751bb4f81 Save the return address in %a1 across the vfork syscall instead of %a0. 2000-12-02 17:03:06 +00:00
scw
c586587e47 Restore %a0 after the call to sigprogmask(2) since an ELF kernel 
will stomp on it due to SVR4 ABI compliance...

4dab4ff2ca 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.

30dca7f7db Add __msgctl13(), __semctl13(), and __shmctl13() (symbols are __RENAME()'d 
in their respective header files).  Add PSEUDO stubs for the old versions
of these system calls.

Note that __semctl13() doesn't require the extra stub that the old
semctl()/__semctl() did, as the SUSv2 version takes variable arguments,
and thus does not require the extra indirection.

dc306354b0 Move the bswap functions from libutil to libc (this bups the 
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.

6348b7d5b5 * On architectures using ELF, and conditionally on those in transition, rename 
_ASM_LABEL(cerror) and _ASM_LABEL(curbrk) to _C_LABEL(__cerror) and
_C_LABEL(__curbrk) (or their respective architecture-specific equivalents) to
avoid possible name clashes with identifiers used in user applications.
* Do the same for minbrk on all architectures to avoid a GCC-specific (and
on ELF architectures effectively useless) symbol reference renaming in MI code.

efd37a7da8 Warn about references to the compatibility vfork() (i.e. the vfork() with 
the 4.4BSD non-shared-address-space semantics), and direct the user to
include <unistd.h> to generate the correct reference.

This warning isn't about an ABI compatibility issue, but the new vfork() is
considerably faster.
