YES!  Looky:

  Breakpoint 1, 0xc00037a0 in start_here ()
  3: x/5i $pc
  0xc00037a0 <start_here>:	lis	r2,-16368
  0xc00037a4 <start_here+4>:	ori	r2,r2,42032
  0xc00037a8 <start_here+8>:	addis	r4,r2,16384
  0xc00037ac <start_here+12>:	addi	r4,r4,624
  0xc00037b0 <start_here+16>:	mtsprg	3,r4
  (gdb)
