Get constants of undefined types in IR
Hello all,
I would like to obtain a constant that is initialized with a value of type cpu_set_t, a type which is defined by Pthreads. The problem is that a variable of this type cannot be cast to an int value, even in C source code. I tried get methods from Constant or ConstantInt classes, but with no result.
How can I obtain such constant object in IR?
Thank you,
Iulia

Thank very much you for your answer. Following the indications in your mail, I obtained one of the 16th elements as below:
static cpu_set_t getCpuAffinityElement(cpu_set_t affinity, int index) { cpu_set_t mask; CPU_ZERO(&mask); for(int i = index * sizeof(unsigned long); i < (index + 1) * sizeof(unsigned long); i++) { CPU_SET(i,&mask); } CPU_AND(&affinity, &affinity, &mask); return affinity; }
That looks like a weird function, but it’...
