-mtune uses all available instructions. By default, all instructions
are enabled.

But the docs say that -mtune only uses non-generic insns when -march is also
given.

Then you should use -mtune=i586 or an option not to

As operands to most operators (or as an expression on their own), but apparently
not (generally) to []. Beyond that, as with ot
Hi Matt,
Does the assembler allow for both ldrsheq and ldreqsh? (the latter version is
what the ARM docs indicate).
Nope, just ldreqsh.
When will I be able to get a canned version of the updated tool-chain?
The fix is in the latest binutils release (v2.20), so you can get that
from wher
Thank you, Nick. Much appreciated. Does the assembler allow for both ldrsheq
and ldreqsh? (the latter version is what the ARM docs indicate).
When will I be able to get a canned version of the updated tool-chain?
Thanks,

That does not work for me.
$ cat nopl.s
cmove %eax,%edx
.align 8
$ as --32 -mtune=i686 nopl.s
$ objdump -dr | grep nopl

Hi Vincent,

Anyway I can now reproduce the problem. It is possible to fix the code in
bfd_elf_m68k_set_target_options to avoid the seg-fault, but I t
Hi Matthew,
Is this the right place for this?
Yes. :-)
The GNU assembler takes the following instruction (for example):
ldreqsh r9, [sl], #0x3f
and assembles it to:
0x00da94d0
This is a bug, now fixed. The current version of GAS assembles it to:
00da93ff
