Subject: transition to using functions for internal signal blocking/restoring
X-Git-Url: http://nsz.repo.hu/git/?p=musl;a=commitdiff_plain;h=2c074b0d6cb2b28c5d1c0ccb2809965f4676efeb;hp=2c074b0d6cb2b28c5d1c0ccb2809965f4676efeb

transition to using functions for internal signal blocking/restoring

there are several reasons for this change. one is getting rid of the
repetition of the syscall signature all over the place. another is
sharing the constant masks without costly GOT accesses in PIC.

the main motivation, however, is accurately representing whether we
want to block signals that might be handled by the application, or all
signals.
