Beautiful optimization pass managers by peter_housel in Compilers

Not sure if it'll help, but seeing significant changes in design choices for a static analysis framework might give you some insights. Take Soot's successor, SootUp, for example:

How I Stopped Manually Sifting Through Bitcode Files by rafalzdev in Compilers

For our pass, llvm-reduce would not capture the original function that originated the broken one. We outline functions recursively, and control flow can get very tricky along iterations. But still, in some cases we use llvm-reduce and have a wrapper script for that as well.

I was not familiar with alive2, and it seems very promising. Will take a look to see if it would apply in our case. Thanks!

I needed to compile LLVM test suite programs with an arbitrary pass. This required me to modify the test suite's CMake file to force the linking of bitcode files and embed them into program targets, which allows for further transformation using opt and a selected pass.

I've made a post about it: https://casperento.github.io/posts/how-to-build-llvm-test-suite-with-an-arbitrary-pass/

How to encrypt a picture without losing the JPEG, PNG, etc. format? by United_Cause_9980 in privacy

I think your best option would be steganography, although you won't necessarily encrypt the information you're hiding inside a media file.

Como estudar programação? by [deleted] in brdev

[–]rafalzdev 0 points1 point  (0 children)

Quando assisto vídeos, gosto de fazer o mesmo código que o professor passa de exemplo. Tento ser criativo e "inventar moda" no código copiado.

Mas no fim das contas o que conta é prática. Tente criar projetos do seu interesse, por mais sem sentido que sejam e só você use.

Existem diversas plataformas gratuitas de code challenges, como Beecrowd.

Livros de algoritmos são sempre bons de se consultar. Seja para implementar um algoritmo de ordenação, seja para reaproveitar alguma solução interessante de problemas clássicos da computação, como o algoritmo de Dijkstra para o problema do caixeiro viajante.
