(gdb) call debug_rtx(*outloc)
(subreg:TI (reg:V4SI 23 xmm2 [99]) 0)
(but of course it looks like NO_REGS doesn't make any sense for this reload)
(gdb) up
#2 0x0849b343 in find_reloads (insn=0x402401b8, replace=0, ind_levels=0,
live_known=1, reload_reg_p=0x87f5a00)
at /space/rguenther/src/svn/gcc-4_1-branch/gcc/reload.c:3953

(gdb) call debug_rtx (insn)
(insn 58 57 59 2 (set (subreg:TI (reg:V4SI 23 xmm2 [99]) 0)
(lshiftrt:TI (subreg:TI (reg:V4SI 96) 0)
(const_int 32 [0x20]))) 711 {sse2_lshrti3} (nil)
(nil))
and we call push_reload with in
(subreg:TI (const_vector:V4SI [
(const_int 9633 [0x25a1])
(const_int 9633 [0x25a1])
(const_int 9633 [0x25a1])
(const_int 9633 [0x25a1])
]) 0)
Looking at reload.c:1018 I don't feel like wanting to dig further ;)
