Subject: test/clone.c: minor fixup
X-Git-Tag: v4.5.18~1116
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=16a03d2e97415afe6cf34172a0aea97a95a0b160;p=strace

test/clone.c: minor fixup
Another bunch of patches from John Hughes merged:
signal.c:
+ SVR4 printcontext(): sigset_t != sigset_t*
+ getcontext returns a value, so print on exit of syscall
+ add UC_FP to ucontext_flags for OS writers that can't spell
+ sys_signal(): special case SIG_{ERR,DFL,IGN}
+ decode_subcall(): only do subcall range checking when needed
bunch of UnixWare updates
aclocal.m4, acconfig.h, configure.in: add test for long long type
