[PATCH] RX: Restrict displacement ranges in "Q" constraint
When using the "Q" constraint in the inline assembler, the displacement value
could exceed the range specified by the instruction.
To avoid this issue, a displacement range check is added to the "Q" constraint.
gcc/
* config/rx/constraints.md (Q): Also check that the address
passes rx_is_restricted_memory-address.
