mycroft 959acd6d47 Looks like I forgot to add this copy of isnan.c. 1999-09-17 21:32:53 +00:00
mycroft b3b07a4c6e Another microoptimization. Take advantage of the addition already having set
the flags for the <=0 comparison.
1999-08-30 18:28:24 +00:00
mycroft 0560606383 Reuse the trick of loading 0.0 (rather than 1.0) and then modifying the
exponent.  It's a bit faster on some machines.

augustss 75d2dfe657 Remove more unused mulexp variables. 1999-08-30 15:11:32 +00:00
mycroft 5f34ffabca ldexp(denormal, exp>1023) would generate the wrong result in all non-overflow
cases.  Totally rework this code to fix this bug *and* make it faster.
1999-08-29 22:45:32 +00:00
mycroft 0ae41d0984 Use the C version of ldexp(). The assembler version was broken in several
ways (ldexp(0.0, 5000) returned +Inf, didn't do normalization/denormalization,
etc.).
1999-08-29 19:08:44 +00:00
mycroft ea4b733810 Trivial KNF. 1999-08-29 18:39:35 +00:00
mycroft ed01c49a3f Use the C version. The assembler version was just transliterated (and buggy)
anyway.
1999-08-29 18:32:36 +00:00
mycroft c8190acc41 Separate isnan() into a separate module, and make isinf()/isnan() use ieee.h. 1999-08-29 18:11:28 +00:00
thorpej 30dca7f7db 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.

matthias 71dd06e171 Go for correctness instead of speed as suggested by Ian Dall. This fixes
pr#port-pc532/7710.

matthias bb36354c10 Fix spurious page faults by double word aligning the source and not the
destination. Thank's to Ian Dall for this fix.

matthias f44e783c10 When invoking ALTENTRY, the arguments may not contain spaces (not even
after the ",") or this will fail when cpp is run with -traditional-cpp.

jonb f23e238690 things like newfs need bswap64 in libc 1999-01-22 14:22:36 +00:00
bouyer dc306354b0 Move the bswap functions from libutil to libc (this bups the
minor of libc and the major of libutil). For little-endian architectures
merge the bnswap() assembly versions with nto* and hton* using symbols
aliasing. Use symbol renaming for the bswap function in this case to avoid
namespace pollution.
Declare bswap* in machine/bswap.h, not machine/endian.h. For little-endian
machines, common code for inline macros go in machine/byte_swap.h
Sync libkern with libc.
Adjust #include in kernel sources for machine/bswap.h.
1999-01-15 13:31:15 +00:00
kleink 6348b7d5b5 * 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.

thorpej efd37a7da8 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.
1998-12-02 19:29:56 +00:00
thorpej e644246e6a 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.

mycroft f948529426 Add some more items to KMSRCS. 1998-02-22 09:04:50 +00:00
thorpej bedc7b48df 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.)

matthias 8c90828457 Introduce ASSRCS. This is set to all the ns32k md assembler source files.
arch/ns32k/Makefile sets SRCS, LSRCS and DPSRCS from this.

cgd 4d7e773266 A foolish consistency... gen, net, and string all get MD sources
specified by including a Makefile.inc from the appropriate MD directory.
stdlib doesn't do that, but there's no reason that it shouldn't (and
it'd be nice to eliminate the 'if's from the MI stdlib Makefile.inc).
