Missing support for arithmetic on booleans and vector types #171
Description
Hi,
C project with decreasing boolean variables
I'm facing an issue with compiling some code with SymCC. When a code tries to decrease a boolean variable, an error comes. This does not occur when I compile with pure clang. Please take a look at the example source code and error messages below. The code would not be used often in practice, but it is generated by a mutataion analysis tool.
Example code:
#include<stdio.h>
#include<stdbool.h>
int main()
{
bool var=true;
var--;
return 0;
}
Error message:
Can't handle Boolean operator %11 = add i1 %10, true
double free or corruption (out)
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.

C++ project
Another error happens when I compile a C++ project. Compiling with Clang has no problem, but with SymCC, it has a compile error. I used regular standard library as below:
export SYMCC_REGULAR_LIBCXX=yes
export CC=/opt/symcc/bin/symcc
export CXX=/opt/symcc/bin/sym++
cmake -DLIBS=/opt/lib .
make
But It has no specific error message, and I cannot share the code, unfortunately. The project code does not contain the above issue code, but it shows...the following error message:
