As you can see bra is generated correctly, but jsr is incorrect.

Look at the relocations.

Right, ld fixes the relocs. Thanks for the tip.

Is m68hc11 target still supported by gas?

2017-09-16 Thread Marek Pietrzak 

Hello,

I'm reviving some ancient stuff and needed to assemble code for m68hc11 
target (I'm going to add a new target for similar microcontroller, but 
it's a different story). I compiled binutils 2.29 for m68hc11 target on 
Fedora 26 x64 and tried this test program:


a1:
    jsr a2
    bra a2
    .skip 10
a2:
    nop

yet the objdump of the assembly shows me this:

test.o: file format elf32-m68hc11

Disassembly of section .text:

 :
   0:    bd 00 00        jsr    0x0 
   3:    20 0a       bra    0xf 
    ...

000f :
   f:    01      nop

As you can see bra is generated correctly, but jsr is incorrect. The 
same for jmp if you try one. That leads me to a suspicion this target 
hasn't been tested and maintained for some time. Is m68hc11 still 
supported?
