Hi clang developers,
I am working on supporting arbitrary precision integer type in clang on local branch. Specifically, I am going to introduce a “bitwidth” like: “int attribute_((bitwidth(N)))”, and directly generate llvm type iN.
Currently I am thinking of two options:
Support the new attribute similar to the “address space”
Create a new “APIntegerType” as a subclass of clang AST Type.
Do you know which option is better/more simple?
Thanks a lot
