mFrame | important element instead of the Controller

I have a re-entrant C++ function whose wasm output is not "thread-safe" when using imported shared memory, because the function makes use of an aliased stack that lives on the shared linear memory on a hardcoded position.

I'm aware that multithreading is not fully supported yet, and if I want to use multiple instances of the same module concurrently, avoiding crashing and data races it's my responsibility, but I accept the challenge.

My X problem is: My code is not thread-safe, and I need it to be by having non-overlapping stacks.

My Y problem is: I'm trying to modify the __stack_pointer so I can implement the stack separation, but it doesn't compile. I have tried with extern unsigned char __stack_pointer; but it throws me the following error:

1. I am making a program that needs to have my FPS counter listed on the top left of the screen. I am using SFML to output my program into a window.
2. I have an FPS.cpp file that contains the class for my FPS counter. There are two methods in this class, "getFPS()" and "update()".

I has Mac OS big sur 11.1, Xcode 12.3(12c33), qt 5.14.2 + qt creator 4.11.1 ( installed with online installer). I made simple project qt quick, build for macos working well, but when i try to build it for iOS emulator, I getting this error:

Here's a minimal, reproducible example:

I am trying to modify an existing example app where the app adds views to the main activity when the user touches the screen. These views are bitmap images that float around the screen. Touching anywhere on the screen adds one of these images at that location.

It does this by creating a new view (the bitmap image) for each touch.

It works fine as is, but I am trying to add a feature where it adds these views programmatically without any user input.

In the below code, I added the onResume() to attempt this functionality. (Adding the same code in onCreate() does not work either.)

Unfortunately it does not add them as I had hoped- instead of adding one every 500ms after the user starts the app, it pauses for 5s and then adds all ten at once.

What do I need to do to implement a delay such that it adds one new view every half second? and why does it do it this way by default?

Thanks!

I have a school assignment to make a program which creates a small window, and when you move the mouse around without clicking it displays the coordinates above in BLACK text, and when you hold and drag the mouse it displays the coordinates above in RED text. I have the program working so it displays the coordinates above the mouse for both events but I'm not sure how to change the color to red when the mouse is being held down. Here is what I have so far:

I have built from scratch Clang on MacOS and I am having problems with it.

Used following to configure Clang for building:

I wrote my MachineFunctionPass following this blog: https://www.kharghoshal.xyz/blog/writing-machinefunctionpass

Then ported it for RISCV target. It was working well. I also add iteration for each instruction to check for Call instruction. It still working, until I tried to write instruction.

This is my MachineFunctionPass:

after having an issue with std::thread's get_id() and printing via fmt (even though I include fmt/ostream.h) I figured I'd put together this simple fmt_test.cpp file (based off of this):
