lukem 88c3eadbfa Add missing __RCSID() 2005-06-12 05:21:25 +00:00
matt 57947b7b48 Make longjmp on vax not use sigreturn. Instead it rewrites the 
jmp_buf into one compatible with __longjmp14 and relies on that
to change that into a ucontext_t suitable for setcontext(2).

matt 17a5fd3419 Start the args after the argc. Return to resumecontext after the entry mask. 2005-04-09 20:46:56 +00:00
he 552a47b805 Revert previous; mhitch has already committed a workaround to ../Makefile.inc. 2004-06-06 17:09:48 +00:00
he 4b896b2324 It appears necessary to add -I. to CPPFLAGS for nslexer.c. This is 
most probably caused by gcc 2.95.3; will be documented in doc/HACKS.
Reviewed by ragge.

drochner 0341f6a45e the WARN_REFERENCES text "include <signal.h> for correct reference" is pointless 
as <signal.h> won't help you, so remove it

drochner cd85223ee2 save errno while trying to install a !SA_SIGINFO trampoline -- this 
is expected to fail with !COMPAT_16 kernels, and we shouldn't
overwrite errno in this case

matt 4b376ded6a Change longjmp on VAX (ELF) to use setcontext instead of sigreturn14. 2004-03-21 18:19:52 +00:00
kleink 8e54f10bf7 * Turn isinf(3) and isnan(3) into C99-style macros. 
* Make it possible for ports to override these (i.e., VAX).
* Remove isnanl(), which was internal to libc only.

lukem a93ea220fc Rework how dependency generation is performed: 
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
  This is a change of behaviour.  If a Makefile wants the clean semantics
  it must specifically append to CLEANFILES.
  Resolves PR toolchain/5204.

* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
  that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES

* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d  depend upon ${DPSRCS}

* Deprecate the (short lived) DEPENDSRCS


Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.

Tested with "make -j 8 distribution" and "make distribution".

nathanw 4fb740b8de Implement pthread_atfork() (in libc, because the required threadlib 
stub behavior is exactly the same as the usual behavior).

ragge d1c2e581d6 Rename __sigtramp1.S to __sigtramp.S. 2002-09-12 18:28:52 +00:00
ragge 2e409d7d44 Fix a signal handler bug originally reported by Hugh Graham some year ago: 
If two signals are sent after each other without the process being run in
userspace between them then the second one will overwrite part of the signal
info stored on the userstack.
Fixed by rewriting and simplifying both the signal delivery code and the
trampoline code. Also bump signal version number to 2.
Rename __sigtramp1.S to __sigtramp.S.
 2002-09-12 18:28:22 +00:00
thorpej c061e6bf8b Enable the libc-provided signal trampoline. The old __sigaction14 
entry point has been replaced by the new __sigaction14() which is a
wrapper around the __sigaction_sigtramp system call (which is itself
not directly exposed outside of libc).

No shared library version change is necessary; no new symbols
are exposed outside of libc.
 2002-07-10 04:29:05 +00:00
thorpej 8aa4d3caec New __sigaction14() system call stub which registers the signal 
trampoline, and the signal trampolines themselves.

NOTE: These are not yet enabled; they will be enabled after further
testing on more architectures.

wiz 92d8b1e9fa Revert previous: .S files are currently compiled with -traditional-cpp, 
so __STDC__ is _not_ always defined.

wiz d56bb7c2ec __STDC__ is always defined on NetBSD. 2002-05-26 11:48:00 +00:00
matt 33ce495df4 Put R6 back in the save and adjust frame size for it. Don't save the 
register in sigset area, put them after the sigset area.
 2002-03-30 05:32:32 +00:00
matt 583d4ad39f Put R6 back in save mask (to make mask used by PLT routines). Adjust frame 
size according.  In _longjmp, deal with sp/fp separately since they stored
in reserve order so movq won't work.
