ABICALLS -> __ABICALLS__

branches: 1.8.2;
Remove all the .abicalls assembler directives - "SYS.h" already has that.

* 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.

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.

* Add Mips ABI changes for ELf shared library support.
From OpenBSD, patched into NetBSD by <bouyer@ensta.fr>.
* Include generic NetBSD/mips <mips/*.h> files, instead of old Sprite names.

Add NetBSD RCSid headers, and change assembly-code LIBC_SCCS id tag string
from "Id:" to "NetBSD:".

Fix a tyop in a comment.

* fix handling of invalid arguments (was jumping to wrong label!)
(found by... running the regress test!)
* clean up punctuation.
* create a proper frame for the child fn that follows the o32 calling
conventions. In particular, leave 4 stack slots that the child
fn can write on, put the GP above them, and invoke .cprestore
properly in light of the child fn arg area. (realized it was a
problem upon inspection, verified using the regress test compiled
-O0.)

ABICALLS -> __ABICALLS__

branches: 1.3.2;
Duh, call the clone's entry point w/ jal, so that when it returns,
it returns to the correct $ra (not the parent's!!).

Cosmetic change.

Add a __clone(2) entry point.

Switch mips to the new libc compat code layout.

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.

Merge all MD __sigaction14_sigtramp.c copies into one:
- sparc and sparc64 were not using version 0 sigcontext when there were
no arguments in the signal version. This was probably a bug.
- vax is using +1 the version numbers of the other archs.
- Only hppa was defining __LIBC12_SOURCE__ so it was getting a working
sigcontext before. all the other ports that supported sigcontext had
the compat code disabled.
[pointed out by thorpej, thanks!]
If we want to remove sigcontext support from userland at least now there
is less work to do so.

branches: 1.7.8;

save errno while trying to install a !SA_SIGINFO trampoline -- this

original slots/regs.

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.

Add syscall stubs for __vfork14(). These are basically copies of Ovfork.S
with the syscall numbers changed.

Since 4.4BSD vfork(2) did not share address space, Ovfork.S could be changed
to be identical to fork.S (modulo syscall numbers). __vfork14.S, however,
needs to remain separate since with a shared address space, the stub needs to
pre-decrement the stack and do an indirect jump to the return address, so that
the shared stackframe is still there when the parent returns. (Obviously,
this does not apply to systems which to not build stackframes on leaf calls.)

brk(2) should update __curbrk, not __minbrk or garbage.

For mips n32/n64 explicitly save the GP reg on the stack, and
restore it _after_ the call to __errno(). Fixes sending the

looks like nobody ever seriously tried the _REENTRANT version of this
code (which, uh, seems the default for a fresh build)... it wasn't
setting up v1 properly (the instruction to set up v1 was after the
return jump, in "reorder" code... i.e. after the end of the function).
That would break error returns from 64-bit syscalls (e.g. checks
in dd and who knows what else) to see if input or output are pipes.
It looks like the non-_REENTRANT version was broken (on the nathanw-sa
branch) in rev 1.9.2.1 and fixed in 1.9.2.2, but the _REENTRANT version
was never fixed, and the broken bits were merged back on to the trunk.

Merge the nathanw_sa branch.

From Arne Juul <arnej@math.ntnu.no>:
Explicilty reload the mips-ABIcall GOT/$gp in cerror().
cerror() gets called from outside libc (e.g., from libposix's rename(),

Mark exect(3) obsolete and bind it to plain execve(2) on all platforms

The original exect(2) from BSD4.2 was enabling bit for tracing
(single-step mode) and calling execve(2). The purpose of it was to generate
a signal for a tracer once the application will change its image to a new
program.

This approach no longer works as:
- exect(2) traces (single-steps) libc and it requires hundreds or
thousands steps before entering a new image
- it's vax and x86 specific code
- this functionality has been moved to the kernel - once a process is
traced it will generate SIGTRAP with si_code TRAP_EXEC and route it to
its debugger
- the side effects and unportability make this interface unusable
- there are no known users of this interface
- it apparently never worked better since day0 of NetBSD ("day0 bug")

Users are requested to move to other execve(2) variants. Calling current
execve(2) as it is the most similar behavior to this one from BSD4.2.

Discussed several times on mailing lists and in PR/51700.

Add warning to exect(3) telling about marking this function obsolete.

This function is prepared to be removed in next libc major bump.

* Include generic NetBSD/mips <mips/*.h> files, instead of old Sprite names.

Add NetBSD RCSid headers, and change assembly-code LIBC_SCCS id tag string
from "Id:" to "NetBSD:".

libc support for mips. libkern hooks are disabled

Clean up deleted files.

Switch mips to the new libc compat code layout.

Move UCB-licensed code from 4-clause to 3-clause licence.

ABICALLS -> __ABICALLS__

branches: 1.9.2;
Remove all the .abicalls assembler directives - "SYS.h" already has that.

* 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.

Warn about references to the compatibility() sigaction(), sigpending(),
sigprocmask(), sigreturn(), and sigsuspend(), and direct the user to
include <signal.h> to generate the correct reference.

mips libc stubs for sig*14 signal API (128bit sigset_t),
plus backward-compatibility for the old 1.3 libc entrypoints.

* Add Mips ABI changes for ELf shared library support.

Rename "syscall" to "_syscall" and provide "syscall" as a weak alias.

branches: 1.7.26;
Since N32/N64 pass the first 8 arguments in registers, we can load all
the arguments into those registers before invoking the syscall having
the kernel syscall handler from having to do that.
