Jason, am I correct to assume that the second SC here:

(gdb) x/10i $lr
0x7fffefdc:     addi    r3,r1,24
0x7fffefe0:     li      r0,295
0x7fffefe4:     sc

This is __sigreturn14


0x7fffefe8:     li      r0,1
0x7fffefec:     sc

and this is exit (process croaks if sigreturn failed).


0x7fffeff0: .long 0x7fffe56c

isn't part of the sigtramp?
