            Bug ID: 31343
           Summary: MIPS: correct behavior of branch to an imm?
           Product: binutils
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gas
          Assignee: unassigned at sourceware dot org
          Reporter: syq at debian dot org
  Target Milestone: ---

Some code like:
      b   (0)
generates the binary like:

00000000 <.text>:
   0: 1000ffff b 0x0
         0: R_MIPS_PC16 *ABS*
   4: 00000000 nop

It will cause something wrong during runtime, normally, 
jump to an address like 0xABCD0000.

Should we just emit an error for the asm code like this, or
emit binary without relocations?

How should we treat the IMM: may be how many bytes?
