Log Message:
s_rintl.c: Reduce FreeBSD diff and fix on ld128 platforms.
EXT_FRACBITS, the number of bits in the _binary encoding_ that stores
the trailing significand field, is never 113. In IEEE 754 binary128,
it is 112, even though there are 113 bits of precision in the set of
floating-point numbers -- the leading 1 bit is implicit in binary128.
So ld128 platforms like aarch64 and sparc64 were skipping the real
definition and just defining rintl as an alias for rint, which is
wrong.
In contrast, LDBL_MANT_DIG, the number of bits of precision in the set
of floating-point numbers (p, in IEEE 754 parlance), is 113 in IEEE 754
binary128. This is also the constant used in FreeBSD libm anyway. So
let's just use that instead of trying to translate it to our private
EXT_FRACBITS (not defined in FreeBSD) with a fencepos terror. And
delete the buggy rintl=rint alias.

CVS commit: src/lib/libm/src
Module Name:src
Committed By: kre
Date: Mon Jan 22 14:26:18 UTC 2024
Modified Files:
src/lib/libm/src: math_private.h
Log Message:
Simply an overly complex way of saying "0 or 1" into a cleaner version.
While here add a commment about how the __i386__ magic LD80C macro
might no longer work on all other arch's as well (if someone can verify
that it still does, or can fix it so that it still works on i386, but
also works everywhere else, then please remove that XXX comment.
The issue I am (perhaps imagining) is the (uint32_t) cast.

Log Message:
avoid uninitialised variable accesses.
if __kernel_rem_pio2() or __kernel_rem_pio2f() are called with "nx" less
than 2, the local variable fq[0] may be accessed uninitialised.
__kernel_rem_pio2() has direct calls with nx = 1, and __kernel_rem_pio2f()
is called with a value starting at 3, but may be decreased to less than 2,
implied by this code , if not actually avoided by the tx[] setup above:
nx = 3;

Fix signed overflow in atan2
As a component of atan2(y, x), the case of x == 1.0 is farmed out to
atan(y). The current implementation of this comparison is vulnerable
to signed integer underflow (that is, undefined behavior), and it's
performed in a somewhat more complicated way than it need be. Change

the MI lrint() code assumes that rounding is done in at most double precision

double-precision mode temporarily here.

Log Message:
Appease static analyzers by making all code paths which assign
values into p,q sane. Get rid of redundant assignment. Indent
for legibility. NFC.
This doesn't create a functional difference, as all callers
test number >= 0x4000 anyway.
To see this, note the following:
- consistently, hx is the high bits of x, lx is the low bits,
x is the float.
- & 0x7fff zeroes the sign bit, as does fabs.
A case where it isn't easy to see that there's no functional
change is y1, which does:
ix = hx & 0x7fff (zero signbit of high bits of x)
y = fabs(x) (this has a zeroed signbit but otherwise same as x)
ix >= 0x4000
pone(y); qone(y)
qone(x) (also pone) do:
ix = hx & 0x7fff
ix in qone and in the calling function are the same number,
and the comparison applies for both, and ix < 0x4000 isn't
possible.
(Also, no explosions seem to happen when I feed it random numbers)
