Disable events on entry to be safe.
It should have been mostly safe for most cases, but for FPU traps
we need to reload the FPU state if we got interrupted at trap entry.
Hopefully fixes:
panic: kernel diagnostic assertion "curlwp->l_md.md_flags & MDL_FPU_IN_CPU" failed: file "/home/source/ab/HEAD/src/sys/arch/x86/x86/fpu.c", line 524
when running tests.
Otherwise the ABSENT_NUMERIC(-1) or CANCELLED_NUMERIC(-2) will be converted
incorrectly to size_t and then down to uint16/32_t.
Picked up by DIAGNOSTIC builds.
Thanks to Michael Forney for the fix for PR lib/52293.
t_cabsl source is in t_cabsl.cxx not t_cabsl.cc - the latter
is what bsd.tests.mk defaults to.
This only broke after my commit of share/mk/bsd.dep.mk rev 1.85
but I don't know why it didn't cause a problem previously.
Fix "make tags" to actually build a tags file:
- Use !commands() instead of !target(), so that the rule actually works
- Write to ${.OBJDIR}/tags for read-only source (don't know why ${.TARGET}
isn't sufficient).
- Only match *.[cly] from ${.ALLSRCS} - just excluding *.h causes failures
because of ${targ}: subdir-${targ} in bsd.subdir.mk.
Thanks to uwe@ for assistance.
inconsistency whether it is biased or not in kernel.
- Obsolete __lwp_settcb() in order to let kernel know new TLS address via
_lwp_setprivate(2). Alternatively, we can call _lwp_setprivate(2) within
__lwp_settcb() like mips, but it is just double handling; we adjust %r2
appropriately in _lwp_setprivate(2) via cpu_lwp_setprivate().
- Make sure that, like other ports, l_private represents address of tcb,
not biased one as in %r2. This guarantees that the returned values from
_lwp_getprivate(2) and __lwp_getprivate_fast() are always same. Also,
we can obsolete PTRACE_LWP_GETPRIVATE() macro.
Now, *_pl_private tests in tests/lib/libc/sys successfully pass, while
no other tests become newly falling.
Found by tests/lib/libc/sys/t_sigaltstack, which passes now, while
no other tests are not falling newly.
XXX
Shouldn't we turn _UC_{SET,CLR}STACK into MI?
When conversion specifier is not a derivative form of "%s", retrieve
input as 32bit integer, and then convert to string literal. Then we
can avoid interpretation from ASCII code to integer, which is
apparently byte-order depended.
When analyzing a build log, the first 'stopped' output
from make, is the end of interesting output.
Normally when a build fails deep down in a parallel build
the log ends with many blockes of error output from make,
with all but the fist being unhelpful.
We add a function dieQuietly() which will return true
if we should supress the error output from make.
If the failing node was a sub-make, we want to die quietly.
Also when we read an abort token we call dieQuietly telling we
want to die quietly.
This behavior is suppressed by -dj or
setting .MAKE.DIE_QUIETLY=no
