Hiļ¼Bob Thanks! Sorry, It is data type complex int. I would like to implement custom instruction for complex numbers e.g, do complex int shift in one instruction. Currently, complex int number is implemented as a array of int with two real int number in Clang.
I am new to Clang and the implementation of the front end are very complicated to me and there are very few debug information dump in Clang. As a result, it is difficult for me to find out the location of the code which cause the error.
