# Programming Exercise 9: Assembly Printing

This is the continuation of hw07. You can continue from your own code or use the parser from the website as starting point.

## Implementation

Print out assembly code from your instruction-selected-and-register-allocated-LLVM-IR.

- Export functions with `.global` and set a proper symbol type and size, e.g. using `.type func, @function` and (at the end) `.size func, .-func`.
- Create a sufficiently large and suitably aligned stack frame, which you clean up before return. If your architecture uses a link register, remember to store it as well. Calculate offsets into your stack frame for all alloca instructions.
- Take care of basic block labels; make use of fallthrough where easily possible, but don't forget to emit proper branches if this is impossible.
- Annotate your function correctly with CFI directives.

Enjoy your working compiler!

# Submission

Send an e-mail to engelke+cghomework@in.tum.de until 2023-01-18, 23:59 with:

- Subject: "Homework 9: YourMatrNr YourName"
- A single(!) .tar.xz file attached named with "hw9-YourMatrNr-YourLastName.tar.xz", which contains a single folder "hw9-YourMatrNr-YourLastName", which contains your submission
- The message body can remain empty
- Include a Makefile with compilation directives s.t. `make` compiles the code
- Specify correct dependencies in the Makefile
- Use `llvm-config --cppflags --ldflags --libs` to find LLVM.
- Avoid external dependencies and complex build systems (no cmake, cargo, etc.)
- Put the source in a single source file (if easily possible)
- Include answers to theory questions as comments in the source file
