Studiu structura tablourilor de tip bool

Atat la concursuri si olimpiade cat si in aplicatii practice, de multe ori se intalneste problema eficientei spatiului, cel mai grav caz al acesteia fiind stocarea unui tablou care contine valori de tip bool. Toate seturile de instructiuni moderne (x86, x64, ARM) pot adresa memorie doar la nivel de octet. Din aceasta cauza, aplicatii care necesita granularitate mai mare pentru elemente ce nu necesita ocuparea unui intreg octet trebuie ori sa sacrifice timp de executie pentru a combina mai multe elemente intr-un singur octet, ori sa sacrifice memorie, punand un singur element per octet si ignorand spatiul ramas neutilizat.

Exista un zvon ca tablourile din C sunt optimizate automat de compilator pe sisteme Linux in cadrul Olimpiadei de Informatica.

Deoarece mediul incurajat in cadrul Olimpiadei este Code::Blocks cu compilatoarele gcc/g++ MinGW, e natural ca si comisia de evaluare sa foloseasca aceleasi compilatoare pe Windows si variantele lor de linux pentru eva

breakingin 1

Reverse engineering a custom VM architecture

This gist contains all the scripts written in the first video of the series.

  • breakingin-add.py sends the first program we wrote: a simple addition.
  • breakingin-good-bf.py implements the more efficient opcode search.
  • breakingin-syscall-search.py tries all syscall numbers.
  • breakingin-write.py demonstrates syscall call convention with the write (1) syscall.

breakingin 1.5

Automating assembly with FASM macros

This gist contains all the scripts written in the intermediary mini-video of the series.

  • macros.inc contains all the macros.
  • breakingin-add-2.fasm is the add program we wrote to test this workflow works.
  • assemble.py contains both the assemble function as well as a test program.
