Changed __float128 to the type _Float128 specified in ISO/IEC TS 18661.
__float128 is used as a fallback if _Float128 is not supported.
New function mpfr_get_str_ndigits about conversion to a string of digits.
New function mpfr_dot for the dot product (incomplete, experimental).
New functions mpfr_get_decimal128 and mpfr_set_decimal128 (available
only when MPFR has been built with decimal float support).
New function mpfr_cmpabs_ui.
New function mpfr_total_order_p for the IEEE 754 totalOrder predicate.
The mpfr_out_str function now accepts bases from -2 to -36, in order to
follow mpfr_get_str and GMP's mpf_out_str functions (these cases gave an
assertion failure, as with other invalid bases).
Shared caches: cleanup; really detect lock failures (abort in this case).
Improved mpfr_add and mpfr_sub when all operands have a precision
equal to twice the number of bits per word, e.g., 128 bits on a 64-bit
platform.
Optimized the tuning parameters for various architectures.
- Keep a bitmap of eligible interrupt-handling CPUs in the pci_chipset_tag_t.
If this bitmap is 0, then we assume that all PCI interrupts should be
routed to the primary CPU.
- Add an optional PCI chipset callback for setting the CPU affinity of
an interrupt.
- When an establishing an interrupt handler, select the CPU that will
handle this irq using the following algorithm:
==> If the irq already has a CPU assignment, keep it.
==> Otherwise, find the CPU with the fewest registered handlers that
is eligible from both a hardware (based on the pci_chipset_tag_t)
and software (based on cpu_info::ci_schedstate.spc_flags) perspectives.
==> Fall back to the primary CPU failing all else.
This variable has served at least 27 years bringing unnecessary
redundancy to the code. It was already redundant at 1993-03-21, when
the code was imported to NetBSD.
When there is a dependency group at the end of a top-level makefile,
this dependency group is not finished properly. This allows to add
further commands to the targets of this dependency group, which was not
intended.
Since at least 1993-03-21, adding other makefiles in a .MAKEFILES
dependency has invoked undefined behavior because the command line
arguments were copied directly into the global makefiles variable,
without a proper strdup. Shortly after that, the word list created by
Str_Words (formerly brk_string) was freed.
This applies to both the -f and the -v and -V options. Luckily it is an
edge case to use these options in .MAKEFLAGS at all.
The -T option had already been fixed at 2000-12-30, but not the other
options.
Parsing a single shell command from a line does not belong in
Parse_File, its proper place is in Parse_Line. Having the whole
detailed code inline in Parse_File is even more confusing.
The tags prevent the structs from accidentally becoming compatible
types.
While here, remove a few typedefs for structs that are single-purpose,
since there is no point in abstracting from the actual representation of
these types.
