[Gcl-devel] Re: mips64 assembler

[Camm Maguire]

Greetings!  What is wrong with this stub attempting a jump to contents
of register $t0?

(gdb) p/x *(ul *)address@hidden
$3 = {0x3c080077, /*lui t0,0x77*/
      0x2508a170, /*addui t0,t0,0xa170*/
      0x8d08a288, /*lw t0,-23928(t0) */
      0x1000008   /* jr t0*/ }

(gdb) c
Program received signal SIGTRAP, Trace/breakpoint trap.
0x01094148 in ?? () /*this is the jump instruction*/
(gdb) i reg t0
t0: 0x2ae13bf0      /*this is the correct address*/

Any help most appreciated!

Take care,
