linux-user: add tkill(), tgkill() and rt_sigqueueinfo() strace
Improve strace support for syscall tkill(), tgkill() and rt_sigqueueinfo() by implementing print functions that match arguments types of the system calls and add them to the corresponding starce.list entry. tkill: Prior to this commit, typical strace output used to look like this: 4886 tkill(4886,50,0,4832615904,0,-9151031864016699136) = 0 After this commit, it looks like this: 4886 tkill(4886,50) = 0 tgkill: Prior to this commit, typical strace output used to look like this: 4890 tgkill(4890,4890,50,8,4832630528,4832615904) = 0 After this commit, it looks like this: 4890 tgkill(4890,4890,50) = 0 rt_sigqueueinfo: Prior to this commit, typical strace output used to look like this: 8307 rt_sigqueueinfo(8307,50,1996483164,0,0,50) = 0 After this commit, it looks like this: 8307 rt_sigqueueinfo(8307,50,0x00000040007ff6b0) = 0 Signed-off-by: Miloš Stojanović <Milos.Stojanovic@rt-rk.com> Signed-off-by: Riku Voipio <riku.voipio@linaro.org>
