gcc calls it as "_mconut", llvm calls as "__mcount".
Change the main name of mcount to "mcount()", and created "_mcount" and "__mcount" entries
to work regardless of which compiler the object was created with.
- add MCOUNT_ENTER, MCOUNT_EXIT macro
- __mcount() function should be aligned
- add "-fno-optimize-sibling-calls" option when PROF. for accurate profiling, it is better to suppress the tail call.
ipfilter: Use the softn (NAT softc) host map size in ip_nat6
calculation. The ipfilter NAT table host map size is a tunable
that defaults to a macro value defined at build time. HOSTMAP_SIZE
is saved in softn (the ipnat softc) at initialization. It can be
tuned (changed) at runtime using the ipf -T command. If the
hostmap_size tunable is adjusted the calculation to determine where
to put new entries in the table was incorrect. Use the tunable in
the NAT softc instead of the static build time value.
psref(9), as well as others(audioread, audiowrite, etc..).
- Rename audio_file_enter to audio_sc_acquire_fromfile, audio_file_exit
to audio_sc_release, for clarify. These are the reference counter for
this sc.
- Introduce audio_sc_acquire_foropen for audio{,bell}open.
- audio_open needs to examine sc_dying again before inserting it into
sc_files, in order to keep sc_files consistency.
The race between audiodetach and audioopen is pointed out by riastradh@.
Thank you for many advices.
This can remove a different copy of audio_exlock_enter() in audio_unlink()
and can use normal one. Also, in audiodetach(), this can set the exlock
at more natual order (before calling audio_unlink()).
No noticeable functional changes are intended.
Thanks for comments, riastradh@.
I had broken this in testlang_parse.y 1.22 from 2021-02-07, when I
extracted the common 'eol' from the statements. Extracting 'eol' had
the effect that the action for the statement was run before the line
number increased.
Now the line numbers in the diagnostics are the same again as before.
For lines that end with a backslash, the reported line number is the one
from the last of these lines, not the first one, also as before. This
feature is not used by any of the current tests though.
It looks as if the original author just didn't know how to declare the
type of non-terminals. The explicit types in the '$' expressions were
all consistent.
No functional change.
The libcurses framework is not strictly typed and thus provides plenty
of ways to shoot yourself in the foot. It's a waste of time debugging
things that a proper programming language can easily prevent.
The function addch expects an argument of type 'chtype'. Passing a
"double-quoted" string does not match this, as 'chtype' is completely
different from a plain 'char'. Instead, functions taking a 'chtype'
must be passed a `backtick-quoted` string.
Previously, there were several concurring styles:
$msg in line %zu of file %s
$msg line %zu of file %s
%s, %zu: $msg
All these are now replaced with "%s:%zu: $msg".
In gicv3_set_priority, read the current priority mask and only update it
if we are lowering the priority. The hardware priority filter is raised
only after taking an interrupt. This makes splfoo/splx without an interrupt
in between considerably cheaper as PMR writes are relatively expensive
compared to reads.
While here, avoid an extra daif read when dispatching interrupts by using
ENABLE_INTERRUPT() / DISABLE_INTERRUPT() instead of cpsie() / cpsid() macros.
