The patch attached to this message allows the building of the gcc-avr
package against GCC 11.
It simply changes the type of member x_spill_indirect_levels of structure
target_reload, defined in file gcc/gcc/reload.h, from bool to int. This
member is only used in file gcc/gcc/reload1.c, where it is incremented as
a integer with the operator ++. In GCC 11, use of this operator on
variables with type bool is forbiden.
At any rate, this member seems to be intended to behave like an integer
elsewhere in the code. For instance, it is passed as the third argument
of the function find_reloads, defined in file gcc/gcc/reload.c, which
accepts an integer as third argument.
Caveat: I did not do extensive tests to check for side effects of this
change.
Best,
Rafael Laboissière
