Hi,
I was trying to feed the "reload" phase with a different hardware
register assignment to pseudo registers (using reg_renumber array)
than the ones produced by local-alloc or global-alloc. However, I get
problems with the following instruction in post-reload.c:391 in
"reload_cse_simplify_operands" function stating that the "insn does
not satisfy constraint".
Can someone please help me if the following instruction has any
specific constraint requirement during register allocation phase?
(insn:HI 100 99 102 8 (parallel [
(set (reg:SI 108)
(div:SI (reg:SI 75 [ prephitmp.6 ])
(reg:SI 74 [ prephitmp.8 ])))
(set (reg:SI 109)
(mod:SI (reg:SI 75 [ prephitmp.6 ])
(reg:SI 74 [ prephitmp.8 ])))
(clobber (reg:CC 17 flags))
]) 196 {*divmodsi4_cltd} (insn_list:REG_DEP_TRUE 99 (nil))
(expr_list:REG_UNUSED (reg:CC 17 flags)
(expr_list:REG_UNUSED (reg:SI 109)
(expr_list:REG_DEAD (reg:SI 74 [ prephitmp.8 ])
(expr_list:REG_DEAD (reg:SI 75 [ prephitmp.6 ])
(expr_list:REG_UNUSED (reg:CC 17 flags)
(expr_list:REG_UNUSED (reg:SI 109)
(nil))))))))
