If I'm running into
/* Figure out which alternative currently matches. */
if (! constrain_operands (1))
fatal_insn_not_found (insn);
'insn does not satisfy its constraints'
By the way, the instruction is
(insn 325 31 44 0 (nil) (set (mem/s:DI (plus:SI (reg:SI 58 r58 [884])
(symbol_ref:SI ("acpi_lr_stat"))) [7427 sec 0 space 0,
cmsmode 0 S8 A64])
(reg:DI 56 r56)) 67 {*movdi} (nil)
(nil))
Asking abstractly, does this mean that I need to support more
constraints in movdi, or does it mean that reload did something wrong?
Thanks,
- Hendrik
