Matthias Klose <doko at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |NEW --- Comment #4 from Matthias Klose <doko at gcc dot gnu.org> 2012-02-21 13:36:44 UTC --- Peter Maydell commented: Specifically the functions exist but return ENOSYS, which is why this: if (getcontext (&c) < 0) abort (); will abort. Trying to get these functions into eglibc for ARM is kind of on the Linaro toolchain group's todo list, but (a) not at a hugely high priority and (b) it will take a little while for them to percolate through eglibc and back into distros anyway, so apps/configure scripts need to be prepared to handle the returns-ENOSYS case anyway.
