    <thetext>MacroAssemblerRISCV64::Imm constrains the integer overloads for I(), S(), and B() with EnableIfInteger&lt;T&gt;, but EnableIfInteger is not defined in WebKit. These are the only references to that name.

As a result, RISCV64 builds that parse MacroAssemblerRISCV64.h fail when ENABLE(ASSEMBLER) is enabled.

The existing codebase already uses C++20 std::integral for this kind of constraint, so these overloads should use template&lt;std::integral T&gt; instead.</thetext>
