While formally GP is not a callee-saved register, for static linking
the link time optimization described in section 3.2.3 of the "Calling
Standard for Alpha Systems" allows the caller to rely on GP being the
value needed within setjmp() - and not restore it after return if setjmp
and the call site share a GP value.
This fixes longjmp/setjmp for statically linked programs, e.g. /rescue/csh
or the static tcsh variant from pkgsrc.
Changes from tzdata2013a to tzdata2013b:
Changes affecting current and future time stamps:
Haiti uses US daylight-saving rules this year, and presumably future years.
This changes time stamps starting today. (Thanks to Steffen Thorsen.)
Paraguay will end DST on March 24 this year.
(Thanks to Steffen Thorsen.) For now, assume it's just this year.
Morocco does not observe DST during Ramadan;
try to predict Ramadan in Morocco as best we can.
(Thanks to Erik Homoet for the heads-up.)
Changes affecting commentary:
Update URLs in tz-link page. Add URLs for webOS, BB10, iOS.
Update URL for Solaris. Mention Internet RFC 6557.
Update Internet RFCs 2445->5545, 2822->5322.
Switch from FTP to HTTP for Internet RFCs.
so we need to retry if curlwp took a context switch during the call.
Otherwise, CPU-local invariants can get screwed up:
panic: kernel diagnostic assertion "cur->pcg_avail == cur->pcg_size" failed
This is (was) very easy to reproduce by just running:
while : ; do RUMP_NCPU=32 ./a.out ; done
where a.out only calls rump_init(). But, any situation there's contention
and a pool doesn't have emptygroups would do.
