Hi Andrew,
Here is a simpler testcase, with the resulting assembly attached below
int main() {
asm ("nop" "\n"
"\t" "nop" "\n"
"\t" "nop");
asm volatile ("nop" "\n"
"\t" "nop" "\n"
"\t" "nop");
}
objdump --disassemble-all -M intel -M

Hi Steven,
Thanks for reaching out. The project is still in very early stages. So
far we have taught the analyzer the basic behavior for
PyLong_FromLong, PyList_New, and Py_DECREF via known function
subclassing. Additionally, Py_INCREF is supported out of the box.

From what I can see below. You do. The case is exactly this.

On the contrary, code compiled with gcc with or without the applied patch

Some transformations treat 1-bit types as a synonym of _Bool and mix the
types in expressions, such as:

_Bool _3;

On a Microsoft Windows target the following (placed inside a function of
