Compilers don’t have to disassemble instructions, so the fact that x86 is hard to disassemble doesn’t matter. And it’s not actually hard in practice if the binary contains labels for function starts. Neither x86 nor arm are easier to compile for, because they both have different quirks that cause headaches. X86 has two operant forms, which require more work. Arm has restrictions on conditional jump distance and immediate encodings, which requires more work. So, an instruction set that had no two operant forms like x86 and that allows any instruction to have any sized immediate would probably be easiest to compile form. Allowing any instruction to have a 32-bit or even 64-bit immediate would lead to either all instructions being huge or to variable length instructions. X86’s use of variable length instructions allows 32-bit immediates everywhere, so in that sense, it makes compiling easier.
