xsznix / js-y86 Goto Github PK

I have added a license to the parent project :)

The "top of the stack" is traditionally drawn on the bottom with decreasing values, while the "bottom of the stack" is drawn on the top with increasing values. The simulator has it backwards though - smaller addresses are found near the top of the page, while larger addresses are at the bottom. It'd be nice to see the stack in its current form in the simulator reversed, or at least have an option to do so.

@xsznix Ran into this in my fork (for a class I TA)

Check out what happens when you attempt the following instruction:

irmovl 0x1000, %esp

Hello! Great job on this project. I've been using it for the same CS class you're in and it's a wonderful interface for testing our programs. There's a minor issue with your display in Firefox on my Mac, which prevents me from using it in that browser. The issue doesn't present itself in Safari.

The image should show it all. When ebp and esp jump down, there is not printed output for them.

This may be a case of Firefox not supporting some JS feature that you utilize, and Safari doing so. I don't have time today to dig into your source. In any case I thought I'd let you know!

Is there a bug with cmovl? (cmovq seems to be working, doing the same cmovl should do.)
As far as I know conditional moves should be the same in y86 and y86-64. So shouldn't cmovq be cmovl?

See here: EBP and ESP between rows, below the row that they should be pointing to.

Title says it all, image reinforces the point

I didn't find an access to the %r8d register for example. why not all the registers appears in your implementation
