.ll file by clang crashes tsar #3

Open mishapankin opened 1 year ago

mishapankin commented 1 year ago

Проблема

Если попытаться анализировать файл, полученный с помощью clang, а не tsar, то tsar падает.

Воспроизведение

  1. Создать файл bug.c 
    int main() { return 0; }
  2. Скомпилировать файл с помощью clang 
    clang bug.c -emit-llvm -S
  3. Запустить анализ 
    tsar bug.ll --print-all
