What are some options to test ARM assembly that some compiler outputs under Windows? QEMU is not an option, right?
So, I've designed a programming language called AEC and I've made an AEC-to-x86 compiler and an AEC-to-WebAssembly compiler. I am thinking about developing an AEC-to-ARM compiler.
A little problem is: ...

How is Rosetta 2 capable of translating x87 instructions (which are stack-based) to ARM machine code (where the FPU is register-based)?
Rosetta 2 is a program that enables the new ARM-based Macs to run programs for old x86-based Macs by translating x86 machine code to ARM machine code. But how does it do that? What seems especially ...

How do I explain to a syntax highlighter to highlight `a` differently in `load s0, a` (where it is a hexadecimal constant) and `regbank a`? [duplicate]
In the syntax highlighter I have implemented in my PicoBlaze Simulator in JavaScript, the assembly code
address 0
load s0, 0
load s0, a
regbank a
is highlighted as ...

What are the advantages and disadvantages of the callee versus caller clearing the stack after a call?
This is more a question about compiler design than language design, but in low level languages, when a function is called, the parameters are pushed onto the stack, and when the function returns, the ...
