- - OCTEON kernel seems OK, something in my private configuration?
[6] - vax vs c++ exceptions issue, same as it ever was
[7] - fails just as poorly in gxemul/landisk as GCC 9
-[8] - i386 seems to have a signal delivery issue. GCC 9 or 10 kernels are
- unable to reboot properly, and GCC 10 atf runs hang in signal delivery.
- bisection so far has reduced bug introduction between 2020-05-08 and
- 2020-05-15. possibly pthread or condvar changes in this period.
+[8] - i386 seems to have a signal delivery issue. pthread tests hang and then
+ complain with eg:
+ threads_and_exec: q[ 627.6700846] sorry, pid 3154 was killed: orphaned traced process
+ this problem occurs with GCC 9 as well.
[9] - x68k/stand fails with:
link loadbsd/loadbsd.x
loadbsd1: program header #1 is not loadable
- may be due to it pulling in libc sources that get TLS marked?
+ problem is understood (thanks tsutsui@): previously loadbsd was linked
+ against normal userland libc components for m68k, which allows it to
+ detect running on m68000 CPU and sanely fail, instead of an barf error.
+ new gcc built libc includes TLS support, that isn't compatible with this
+ and the conversion process fails. can be fixed by using libkern instead,
+ and accepting the poor error on m68000.
