nathanw 4fb740b8de Implement pthread_atfork() (in libc, because the required threadlib 
stub behavior is exactly the same as the usual behavior).
 2003-02-13 02:50:48 +00:00
petrov 12784e54c3 Correct unsigned to float conversions, add license, adjust style. 2003-02-06 20:23:35 +00:00
martin 912ab5ad59 Check how the compiler expects the return value of this function 
by testing SOFTFLOATSPARC64_FOR_GCC.

Should fix PR port-sparc64/20140.
 2003-02-01 09:19:58 +00:00
thorpej 3fdac2b8c5 Merge the nathanw_sa branch. 2003-01-18 10:52:16 +00:00
chs cab484e445 move includes to the top so that this builds in libc context too. 2002-10-29 04:40:55 +00:00
petrov ade04d7707 Compile with an ISO C preprocessor. 2002-10-29 00:22:18 +00:00
chs c04f87a03e remove setjmp/longjmp from libkern, they're not used. 2002-10-27 18:45:11 +00:00
chs c5a350ef59 use %g5 instead of %g7 (since we want to use %g7 for the cpu_info pointer 
in the kernel).  resync libc and libkern versions of this file.
 2002-10-27 18:41:27 +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entry point has been replaced by the new __sigaction14() which is a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 86223838f0 Also need <machine/fsr.h> and <machine/psl.h>. 2002-07-10 03:27:23 +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.
 2002-05-26 12:24:55 +00:00
wiz d56bb7c2ec __STDC__ is always defined on NetBSD. 2002-05-26 11:48:00 +00:00
bjh21 6bd902a1db Adapt for recent lib/libc/softfloat changes. 2002-05-22 10:20:20 +00:00
bjh21 010758bf16 Add SIGFPE support to SoftFloat, so fpsetmask/fpgetmask now work. A new 
variable, float_exception_mask (#defined to _softfloat_float_exception_mask)
contains the current exception mask.
Also make the argument to float_raise into an fp_except.
Also synchronise file header comments between files.

eeh 22abdf821b Use large (-fPIC) relocations. 2002-05-07 01:34:21 +00:00
eeh b92211c580 Go back from using %g2 (an application register) to %g7 (a system register) 
for syscall returns.
 2002-05-07 01:32:46 +00:00
eeh 1d63620b87 Add support for large -fPIC relocations. 2002-05-07 01:31:33 +00:00
bjh21 251de84ccc Consistently declare the types of float_rounding_mode and float_exception_flags 
as fp_rnd and fp_except respectively.
 2002-05-06 19:05:00 +00:00
thorpej 046b47950e Add a .register directive to appease newer gas. 2002-05-05 17:51:46 +00:00
bjh21 25540eca7e All the versions of softfloat-specialize were practically identical, so replace 
them with a single one.

jmc a7839b0fdc Fix typo in previous commit 2002-03-27 03:43:39 +00:00
jmc a1fe3592c6 Correct mistaken signature for _Qp_dtoq. It gets a double passed in, not 
a pointer to double which causes obvious errors on evaluation
 2002-03-27 03:41:54 +00:00
jmc f40c307405 Move names for softfloat lib that _Qp functions call into _softfloat_ 
namespace
 2002-03-04 21:26:39 +00:00
simonb 2d8577fb83 Clean up some rampant code duplication wrt ieee number handling: 
- Add alignment-safe double and float unions.
 - Use the above for the __infinity and __nan constants on all
   architectures that use the standard ieee754 representation of
   those constants.
 - Add a single copy of various ieee754 math functions (frexp, isinf,
   isnan, ldexp and modf) that had numerous duplicates among the
   arch-specific directories.
 - Use the above functions on all architectures where the generic C
   versions where used.  Architectures that had local assembly
   routines are untouched (for those functions only).
 2002-02-19 13:08:12 +00:00
jmc 4b4c3144ba Enable the _Qp* routines to be built always and allow full softfloat to be 
pulled in if MKSOFTFLOAT gets enabled.
 2002-02-05 07:54:01 +00:00
jmc d9c86555ad Add softfloat and quad softfloat setup for sparc64 (thanks to Andrey Petrov 
for most of this. I just integrated the build).

This adds proper functions for the _Qp* parts of the sparc64 ABI (which
handle quad softfloat). The routines work but need additional testing.
However if the compiler calls these currently bad things (core dumps)
will happen as gcc 2.95.3 generates bad calls for these.

Until that problem is fixed in the toolchain -msoft-quad-float cannot be
enabled as the default option for all builds (but the routines need to be
in libc as libgcc contains some references to these and anything including
it via --whole-archive will need the symbols to at least resolve).

thorpej ac8c1c29e9 * Add WSYSCALL() to SYS.h, which creates a system call with an 
internal name and a weak alias for the name.
* Add a WEAKASM syscall list, and process it.
* Make sysarch() have an internal name (_sysarch()).
 2002-01-14 00:55:55 +00:00
thorpej 5d3e829423 Add internal names for fp{get,set}{mask,round,sticky}(), and 
externally-visible weak aliases for the internal names.

tv 26375a1710 Remove -Wa,-Av9a hack from <sys.mk> and relegate it to the places that need 
it (kernel and libc).

The current version of the gas assembler in the tree (2.11.2) already
defaults to generating object files for "-Av9 -64", supporting V9
instructions in ELF64 object format.  "-Av9a" is only needed for specific
parts of the NetBSD base sources, and not for all third-party code.

thorpej f98eeabaa2 sparc64 version, cloned (har har!) from the sparc version and tweaked. 2001-07-23 07:35:44 +00:00
thorpej fed292651f From rev. 1.11 of the 32-bit version: 
Add a macro "CALL()" to call a function correctly in the pic and non pic
case. Write ERROR() in terms of call.
