Here's a simple test, for starters:

$ cat t.s
.globl foo
.space 8
.ent foo
foo:
.space 16
        b foo
.end foo
$ as -64 -KPIC t.s -o t.o
$ objdump -dr t.o

0000000000000008 <foo>:
        ...
  18:   10000000        b       1c <foo+0x14>
                        18: R_MIPS_PC16 foo+0x14
[snip]
$ ld -melf64btsmip t.o -o t
$ objdump -dr t
[snip]
00000000100000e8 <foo>:
        ...
    100000f8:   10000001        b       10000100 <foo+0x18>
