Message-ID: <OF47E5ECAA.FB9CAD3F-ONC225774A.004A51CD-C225774A.0051B95D@il.ibm.com> (raw)


Hello,

I have a question regarding code generation for a new target I'm working
on.
I am using GCC 4.6.

In reload pass  the following first instruction is replaced with the
second one after spilling reg 182 to the stack.  The problem is that
the generated new instruction does not have a valid address format and
I'm not sure why it was considered as a valid replacement.
Any help on how to resolve this is appreciated.

(insn 282 150 151 13 jctrans.c:109 (set (reg:SI 12 r12)
        (mem/s:SI (plus:SI (reg/v/f:SI 182 [ incomp ])
                (const_int 8 [0x8])) [6 *incomp_85 S4 A32])) -1 (nil))

(insn 282 150 151 13 jctrans.c:109 (set (reg:SI 12 r12)
        (mem/s:SI (plus:SI (mem/c:SI (plus:SI (reg/f:SI 63 r63)
                        (const_int -12 [0xfffffff4])) [56 %sfp+-12 S4 A32])
                (const_int 8 [0x8])) [6 *incomp_85 S4 A32])) -1 (nil))

Thanks,
Revital
