Hi,
I found that TX39 disassembler always disassembles "jalx" instruction, but TX39 processor doesn't have such according to specification from Toshiba. But objdump clearly produce following code:
bfc00da0: 77f00c7d jalx 0xbfc031f5
This seems to be wanted behaviour? In source code of binutils, I see a comment in opcodes/mips-dis.c in function print_insn_mips ():
/* We always allow to disassemble the jalx instruction. */
But what sense does it make if this instruction is not supported by r3900 mips variant ?
Best regards,
coderat
