Add fast softint support for PowerPC (though only booke uses it).
Redo FPU/VEC support and add e500 SPE support.
Rework trap/intrs to use a common trapframe format.
Support SOFTFLOAT (no hardfloat or fpu emulation) for BookE.
change, we should be fully conformant with the N32 and N64 ABIs.
Add {fpclassify,infinity,isnan,ininf,signbit}l_ieee754.c back to lib/libc/gen.
Note that infinityl_ieee754.c will work with either 64-bit, 80-bit, or
128-bit long doubles.
* Years in the [90,99] range are considered to be in 1900.
* Years in the [0,89] range are considered to be in 2000.
This makes my MacBookPro2,2 be recognized as from 2007 instead of 1907, which
in turn lets ACPI (and many other things!) work.
Fix proposed by jmcneill@ as an alternative to my workaround in acpi_quirks.c
sent to port-i386@.
now automatically picked based on the ABI of the target the library
is compiled for.
(the host libc symbolname to override still needs a little attention
based on the system version)
one had the problem of bypassing the syscall layer and doing a
function call into the kernel directly. Therefore there was no
way for users of librumpclient to specify compat. The new model
pushes the compat handling in the kernel and leaves only the task
of selecting the right syscall number to the client.
This change also introduces a stable ABI for rump syscalls, i.e.
it is possible to use the same syscall client library both on NetBSD
5.0 and -current and get the syscalls resolved to the right place
depending on the ABI at the time the client binary is compiled.
A list of what to be called when will have to maintained separately
simply because this information is not available in syscalls.master
-- in the case of the normal kernel we always want to resolve a
newly linked syscall to the latest version, whereas in rump we
might want to resolve a syscall to a -current kernel to the 5.0
compat call (because our client namespace is 5.0). This information
in maintained in rump_syscalls_compat.h with the current format:
/* time_t change */
#if !__NetBSD_Prereq__(5,99,7)
#define RUMP_SYS_RENAME_STAT rump___sysimpl_stat30
....
If no compat override is given, a syscall resolves automatically
to the latest version of the syscall.
Also, this change autogenerates forward declarations for all syscall
types where it is possible (i.e. ones without typedef insanity).
This makes it possible to include rump_syscalls.h without including
rump.h.
