- 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).
register name. the rule is that extended asms should have the
regsiter-prefix %s escaped by doubling them, but non-extended asms
don't do the escaping thing, so there the %s should not be doubled.
- use "U" suffix for unsigned constants
- use "L" suffix for long constants
- use "UL" suffix for unsigned long constants
- use hexadecimal instead of decimal
Fixes build problems with vi (now that warnings/errors are enabled) on
mips, powerpc and arm platforms.
to <sys/types.h> and <sys/stdint.h>.
* Add a new C99 <stdint.h> header, which provides integer types of
explicit width, related limits and integer constant macros.
* Extend <inttypes.h> to provide <stdint.h> definitions and format
macros for printf() and scanf().
* Add C99 strtoimax() and strtoumax() functions.
* Use the latter within scanf().
* Add C99 %j, %t and %z printf()/scanf() conversions for
intmax_t, pointer-type and size_t arguments.
XXX if you have libc after citrus locale import, please recompile libc,
and your applications that use mbstate_t (rather rare). really sorry
for the mess.
one to perform a kernel traceback of any (non-swapped-out) process in
the system. For example, to show the traceback for PID 178:
db> t/t 0t178
trace: pid 178 at 0xabcd68
_mi_switch(0x109f60) + 164
...
db>
- MB_LEN_MAX is increased to 32.
- To ensure binary compatibility for old executables
under multibyte locale, versioned setlocale is added.
- __mb_len_cur definision is added in setlocale.c
and enable it in stdlib.h .
It is also important for multibyte locale stuffs,
but I just forgot.
- for sizeof(void *) == 8 arch, this is mandatory. MHLEN is too small
already (less than 80) and there are chances for unwanted packet loss due
to m_pullup restriction.
- for other cases, the change should avoid allocating clusters in most cases
(even when you have IPv4 IPsec tunnel, or IPv6 with moderate amount of
extension header)
portmasters: if your arch chokes with the change (high memory usage or
whatever), please backout the change for your arch.
an unsigned char, since that is what the `tas' instruction uses.
While I'm here, implement the __cpu_simple_lock family of routines.
Why? One, because they're easy. Two, so Steve can get master/slave
MVME systems talking across the backplane. :-)
contains the values __SIMPLELOCK_LOCKED and __SIMPLELOCK_UNLOCKED, which
replace the old SIMPLELOCK_LOCKED and SIMPLELOCK_UNLOCKED. These files
are also required to supply inline functions __cpu_simple_lock(),
__cpu_simple_lock_try(), and __cpu_simple_unlock() if locking is to be
supported on that platform (i.e. if MULTIPROCESSOR is defined in the
_KERNEL case). Change these functions to take an int * (&alp->lock_data)
rather than the struct simplelock * itself.
These changes make it possible for userland to use the locking primitives
by including <machine/lock.h>.
big-endian. i386, pc532 and vax still include <machine/byte_swap.h>
and define macros for the {n,h}to{h,n}*() functions. mips also
defines some endian-independent assembly-code aliases for unaligned
memory accesses.
that is priority is rasied. Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.
This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).
XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX. This platforms still have this bug until their
XXX spl*() functions are fixed.
convention (not that it should matter for assembly).
* Provide an additional set of _C_LABEL() macros for ELF.
* Provide a PIC_PLT() macro for the benefit of ELF.
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.
