Description
|
In .ad file, the format
operand no_rax_RegL()
%{
constraint(ALLOC_IN_RC(long_no_rax_rdx_reg));
match(RegL);
match(rRegL);
match(rdxRegL);
format %{ "RCX" %}
interface(REG_INTER);
%}
If register selected other than RCX the output of PrintOptoAssembly will be wrong. The output will be confusing since the real case with no rcx selected.

Evaluation

We can detect and complain about some version of this problem but I think it would be better if formats were never specified for register operands.
