Algorithm

Ограничения ввода:

  1. Угол в радианах n
  2. Ограничения n: (|n| <= 1) P.S. такие ограничения установил, а не |n| < pi / 2, потому что точности C не хватает для точного просчёта последовательностей и погрешность очень резко повышается до значения более 0.05%

Критерии на 4/10

4_1

  • В проекте это файл solution.c

4_2

  • Компиляция без отладочных опций:
gcc -O0 -masm=intel solution.c -S -o solution_1.s
  • После компиляции создался файл solution_1.s, комментарии написаны в нём

4_3

  • Использованы аргументы командой строки и ручное редактирование, получился файл solution.s
gcc -O0 -Wall -masm=intel -S -fno-asynchronous-unwind-tables -fverbose-asm -fcf-protection=none solution.c

4_4

  • Программа скомпилирована и скомпонована без опций отладки
gcc solution_1.s -o main -lm

4_6

  • Отчёт сформирован.

Критерии на 5/10

5_1

  • Функции с передачей данных через параметры использованы solution.c
long double bernoulliNumber(int n);
long long factorial(int n);
long double tanhNumber(long double angle, int threshold);

5_2

  • Локальные переменные использованы(Например, angle, maxThreshold, threshold в функции main и result, n , n2 в функции tanhNumber). Это можно увидеть в файле solution.c
long double angle;
int maxThreshold = 11;
int threshold = 1;
long double result = 0;
int n = 1;
int n2 = n * 2;

5_3

  • В ассемблерную программу при вызове функции добавлены комментарии, описывающие передачу фактических параметров и перенос возвращаемого результата. Это можно увидеть в файле solution.s

5_4

  • В функциях для формальных параметров добавлены комментарии, описывающие связь между параметрами языка Си и регистрами (стеком). Это можно увидеть в фале solution.s

5_5

  • Информация добавлена в отчёт
