joerg | Pass PICFLAGS down to cc-as-as and use __PIC__ to decide if it is small
vs big PIC mode. Retire -DPIC and -DBIGPIC.
|

| 16-Jul-2013 |
matt | Use SYSTRAP.
Don't use the PLT to call CERROR
Use LEA_LCL / GOT_SETUP
Remove non-__ELF__ code.
Make __minbrk and __curbrk hidden and avoid using the GOT for them.
Convert to motorola syntax.

matt | Convert to normal Motorola syntax for addressing.
%r@ -> (%r)
%r@- -> -(%r)
%r@+ -> (%r)+
%r@(n) n(%r)
etc.
No object differences.

phx | branches: 1.15.6; 1.15.12;
SystemV-R4 ABI for M68k returns pointers in %a0, so we have to make sure
that CERROR returns -1 in %a0 in addition to %d0 and %d1, to make functions
like mmap(2), mremap(2), shmat(2) or sbrk(2) return -1 in case of an error.
A side effect of this bug was a segfault caused by jemalloc, when mmap()
failed.

agc | branches: 1.14.38; 1.14.46;
Move UCB-licensed code from 4-clause to 3-clause licence.
Patches provided by Joel Baker in PR 22280, verified by myself.
|
| 1.13 |
| 25-Oct-1999 |
thorpej | Add register prefixes.
|
| 1.12 |
| 18-Oct-1999 |
itohy | ELF PIC support.
|
| 1.11 |
| 02-May-1999 |
kleink | branches: 1.11.2;
We can shave off a register-register move when using the SVR4 ABI: __errno()
will return its pointer result in a0.
|
| 1.10 |
| 29-Apr-1999 |
kleink | Declare cerror using _ENTRY() to get, among other things, a .type statement.
|
| 1.9 |
| 14-Jan-1999 |
kleink | * 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.
|
| 1.8 |
| 06-Oct-1998 |
kleink | Declare one of {__errno,errno}, depending on _REENTRANT.
|
| 1.7 |
| 01-Jul-1998 |
thorpej | Use _C_LABEL() to generate C labels.
|
| 1.6 |
| 07-Nov-1996 |
jtc | Change __REENTRANT to _REENTRANT, the latter is used Solaris and I can
think of no good reason to be different.
|
| 1.5 |
| 07-Nov-1996 |
jtc | Changed so that when __REENTRANT is defined, cerror calls __errno()
for the address of a variable used to store the error number instead
of writing to the global errno.
In a multi-threaded program, __errno() will return a pointer to a
thread-specific variable.
|
| 1.4 |
| 13-Dec-1995 |
thorpej | New-style RCS ids. Use the RCSID() macro where appropriate.
|
| 1.3 |
| 04-Aug-1994 |
chopps | fixed ld.so to properly save all regs when binding PIC functions. We no
longer need the special case (PIC) code to push args when calling cerror.
|
| 1.2 |
| 02-Apr-1994 |
cgd | branches: 1.2.2;
have cerror DTRT on returns, w.r.t. quads and -1. it needs to be done
here (think of syscall(SYS_lseek,...)). also, kill bogus lseek thang.
|
| 1.1 |
| 25-Nov-1993 |
paulus | Machine-dependent files for generic m68k machines (copied from hp300),
modified to support shared libraries.

sborrill | Pull up the following revisions(s) (requested by phx in ticket #1085):
lib/libc/arch/m68k/sys/cerror.S: revision 1.15
Ensure functions like mmap(2), mremap(2), shmat(2) or sbrk(2) return -1 in
case of an error. A side benefit of this is to fix a segfault caused by
jemalloc when mmap() failed.

tls | Rebase to HEAD as of a few days ago.

yamt | sync with head.

this commit was splitted into small chunks to avoid
a limitation of cvs. ("Protocol error: too many arguments")
