he ea56bcee84 Hide the register number constants behind an _R_ prefix, and also 
rename FPBASE to _FPBASE, so that we avoid polluting the user's
name space when e.g. <sys/ptrace.h> is included.  Previously, the
PC symbol in mips/regnum.h would conflict with the declaration of
the external variable by the same name in termcap.h, as discovered
by the ``okheaders'' regression test.

christos adfca9e3e4 This is not needed anymore. 2003-11-25 22:41:12 +00:00
christos 6477735848 m68k does not sigcontext<->mcontext anymore. 2003-11-25 21:27:30 +00:00
uwe 6d08061385 Do not move incoming paramters to callee-save registers when not 
necessary.  Saves about a dozen of instructions.
 2003-11-20 17:55:11 +00:00
uwe b3c165e505 Add _INITCONTEXT_U_MD, we need to clean _REG_SR. 2003-11-20 17:38:08 +00:00
uwe 1e78682585 In pthread__locked_switch set self->pt_uc only when the context is inited. 
In STACK_SWITCH subtract STACKSPACE, not add it (it's zero for now anyway).
 2003-11-20 03:31:02 +00:00
uwe 024d461f8f First cut at pthreads MD code for sh3. Based on m68k version. 
Regression tests still failing: sem, sigalarm.

martin 3e8ef3d56a Fix ucontext conversion macros. From Christian Limpach. 2003-11-11 16:21:05 +00:00
martin d708163f7f All the ucontext <-> {fp}reg macros were slightly simplistic and untested 
before (old gdb support on sparc did not use this).
Pointed out by Christian Limpach.

fvdl c4e432f3bd Make register usage more consistent, also in comparison with the i386 
version, for easier maintenance.
 2003-11-08 21:46:42 +00:00
fvdl 127827f46e Restore %rax correctly during a full context restore (oops). 2003-11-08 21:45:59 +00:00
yamt 71b290e975 use explicit "l" suffixes. (eg. lea -> leal) 2003-10-30 13:56:37 +00:00
fvdl c2405107f1 Correct and simplify computing the return point; just use PC-relative 
addressing.
 2003-10-20 14:50:18 +00:00
fvdl b30e737545 Make sure the stack stays aligned. 2003-10-19 21:45:03 +00:00
chs f58c80fc8f fix typo in previous. 2003-10-12 00:25:25 +00:00
cl bfa716044e SA_SIGINFO support for m68k (libpthread) 2003-09-22 14:45:48 +00:00
cl c6de69ee49 fix pt_trapuc handling errors: 
- movl to address register doesn't set flags (add explicit test)
- clr only clears a word (use clrl)
 2003-09-17 20:08:07 +00:00
cl 89d0cfd21f Remove possible race condition in upcall recycling. 2003-09-07 14:47:44 +00:00

From sparc64 fix by Andrey Petrov <petrov@netbsd>.

petrov 0d472e116b typo in previous commit, annul isn't good there, 
noticed by Eduardo Horvath.
 2003-08-26 17:50:06 +00:00

petrov c139cd4893 Use correct context to switch to. 2003-08-25 22:48:24 +00:00
ragge 644236bf71 Add PT_TRAPUC and pthread__switch_return_point. 
Not tested (as most of the pthread stuff on vax) but at least
allow the system to compile.
 2003-08-25 20:32:13 +00:00
scw 46fc66f7d8 Adapt to Nathan's recent pt_trapuc/pt_sleepuc change. 2003-08-12 14:01:08 +00:00
agc eb7c1594f1 Move UCB-licensed code from 4-clause to 3-clause licence. 
Patches provided by Joel Baker in PR 22280, verified by myself.

matt 0f8d87a96d Update to new world order. **not tested** But will allow builds to 
finish.
 2003-07-09 00:55:45 +00:00
uwe ea81adf86a Not that the branch in SETC doens't have a delay slot, remove the 
.empty comment as it's no longer pertinent.
 2003-07-05 23:01:25 +00:00
marcus 4e24351384 PIC patch from Valeriy E. Ushakov applied. 
Also, removed bogus delay slot flag from branch instruction.
 2003-07-05 22:50:09 +00:00
marcus cccf9dfce5 The field "pt_sleepuc" doesn't exist in struct pthread_st. 2003-07-05 21:27:23 +00:00
nathanw 9639eeaf54 Adapt to pt_trapuc: change STACK_SWITCH to check for a value in pt_trapuc 
and use it preferentially to a value in pt_uc, clearing it once on the new
stack. Move stores into pt_uc back to before the stack switch; storing
after the stack switch opened a one-instruction race condition where an upcall
that had just started a chain could be preempted again, and would bomb when
restarted due to its pt_uc not yet having been updated. Now that pt_trapuc
is what the upcall code writes to, it is safe to store to pt_uc before
switching stacks.

Remove obsolete pt_sleepuc code.

nathanw 1414a095ac Remove PT_SLEEPUC and add PT_TRAPUC. 2003-06-26 01:29:28 +00:00
nathanw 39f9ecfa06 Oops, reordering the PT_STATE/PT_SWITCHTOUC/PT_SWITCHTO assembly 
killed a live value too soon. Fix by using a different register for
the PT_STATE immediate.
 2003-06-24 18:54:56 +00:00
nathanw 96458e8892 Update the switch_return point name in the static case. 2003-06-23 22:50:23 +00:00
uwe b92f152573 First bits of SH3 support. Only _context_u.S is implemented (passess 
cu[1-6] tests), the pthread_switch.S is stubbed out for now.

Code posted by Christian Groessler (cpg at aladdin dot de) to port-sh3.

Compile-tested only.
 2003-06-13 07:45:17 +00:00
nathanw 4bd45b7b3b Oops, that's switch_return_point, not locked_return_point. The perils 
of cut-and-paste.
 2003-06-12 23:19:27 +00:00
nathanw aa6f5de228 STACKSPACE of 16 is too small, given the use of CALLFRAME_SIZ; 
increase to match.
