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.
