------- Additional Comments From rth at gcc dot gnu dot org 2005-08-04 20:48 -------
The reason that we're rejecting the "m" alternative is that we've expanded
"+mr"(blen) to
(set (reg/v:SI 60 [ blen.25 ])
(asm_operands:SI ("") ("=mr") 2 [
(mem/i:SI (plus:SI (reg/f:SI 16 argp)
(const_int 16 [0x10])) [0 d+0 S4 A32])
(reg/v/f:SI 65 [ a ])
(reg/v/f:SI 67 [ b ])
(reg/v:SI 68 [ blen ])
Note reg 60 as output and reg 68 as input. Probably out-of-ssa is
missing the fact that we'd like these variables to be unified.

this code is a part of library (-fPIC in use).
-fomit-frame-pointer won't help.

Could this be related to PR19398: secondary reloads don't consider "m" alternatives?

(In reply to comment #3)
> I can't build the Objective Caml compiler with this gcc error :/
If we change the asm to like so:
asm(""
: "+r" (a), "+r" (b), "+m" (blen), "+m" (out), "=&r" (tmp)
: "m" (d)
: "eax", "edx");
We don't get an error.
Also using -fomit-frame-pointer works around the problem by adding another free register.
What is most likely happening is we are not selecting the secondary constraint.
Oh, reload sucks.
