--- Comment #13 from Uros Bizjak <ubizjak at gmail dot com> 2011-07-17 20:02:40 UTC ---
Looking at the example in Comment #0, RTX expansion pass generates:
;; D.2794_77 = &q + D.2793_76;
(insn 84 83 85 (parallel [
(set (reg:DI 173)
(plus:DI (reg/f:DI 54 virtual-stack-vars)
(const_int -160 [0xffffffffffffff60])))
(clobber (reg:CC 17 flags))
]) pr47744.c:5 -1
(nil))
Why 64bit virtual register to hold &q _address_?
