hello
I find a problem when testing GCC10.0 on aarch64 at -mabi=ilp32 .
The option -mabi=ilp32 should not be used in large code model.
like x86,when using -mx32 and -mcmodel=large together ,it will have error
message
"error: code model ‘large’ not supported in x32 mode".

On aarch64,this is no error message for this option conflict.
