- Subject: [commit] Remove unused function in irix5-nat.c
Hello,
this removes another never-used function, get_longjmp_target in irix5-nat.c.
This hasn't been used in a while; to properly support longjmp on irix
gdbarch support needs to be added to mips-irix-tdep.c instead.
Committed to mainline.
Bye,
Ulrich
ChangeLog:
* irix5-nat.c (JB_ELEMENT_SIZE, get_longjmp_target): Remove.
