callback because el_line updates the legacy LineInfo structure and
we need to notify that the cached copy of the the buffer has changed.
Of course the resizing function can call el_line itself to update
the buffer, so prevent recursion. Bug found by Peter Rufer at Arista.
Doing
fexcept_t ex = 0;
fesetexceptflag(&ex, excepts);
has the effect of _clearing_ all the exceptions in excepts. Using
fesetexceptflag doesn't make this easier, because we would have to
record which exceptions were already raised. So just set the fflags
bits in the fcsr register directly.
i386 Xen PV domU get spurious fpudna traps from userland. Older eager FPU
contact switching code took care of ignoring them. When transitioning
from eager switching to awlays switching, this special handling was
removed, causing "fpudna from userland" panics.
This change restores the previosu behavior where fpudna traps from
userland are ignored on Xen PV domU.

This looks to make macppccd builds with cdrtools-3.02a10.
. In particular, add NetBSD 8.3 to timeline
. Add respective "publication dates" of those points in time
While here, also:
. Fix white space idiosyncracies and opt for https instead of http
. Track some changes made to the FreeBSD version of this file
'disklabel -r -w' writes a disklabel at a wrong sector in
NATIVELABEL_ONLY && !LABELUSESMBR && LABELSECTOR != 0 case
if the target disk doesn't have a valid disklabel, due to
incorrect LABEL_OFFSET value.
Found and investigated on NetBSD/hp300 bootable CD tests.
Maybe this affects ports that use distrib/utils/x_disklabel
but have no MBR support, i.e. only NetBSD/hp300 10.0 and
NetBSD/ews4800mips 9.0 and later.
Should be pulled up to netbsd-10 and netbsd-9.
No floating-point exception traps on RISC-V.
Also don't pass the result of divide-by-zero converted to integer to
usleep. Although the floating-point result of divide-by-zero is
well-defined by IEEE 754 (+/-infinity), the outcome of C conversion
to integer is not. And while on some architectures this might return
zero, on RISC-V it looks like it'll return all bits set. And as of
PR 58184, usleep now honours sleeps longer than 1sec, which means
this will be waiting at least two billion microseconds, or about half
an hour...
So instead, just write the result to a volatile variable.
These instructions can be omitted if the return values are unused.
In contrast, _writes_ to the rounding mode or exceptions must not be
omitted (even if we ignore the return value, which is the old value
of the field).
I think "memory" is the wrong clobber on these asm blocks too; they
can't be reordered around _floating-point_ instructions, while
reordering around loads and stores is fine. But I don't know how to
spell the right thing in gcclish.
- Include fenv.c and fma(3) symbols (which just use the FMADD
instruction).
- Note the .FN symbols in libm for the asm functions. The FN symbols
point at the function _descriptors_; the .FN symbols point at the
first instruction of the function.
XXX Unclear why we have the .FN symbols for asm functions but not for
C functions. I'm not sure we should be exporting them.
