creating an .init section
Hi,
I would like to create an .init section in the LLVM backend. Can anyone shed me the light on how to do it? Do I have to create it in the clang?
Thanks,
Jin

[LLVMdev] How to tell whether a GlobalValue is user-defined
I think this is preventing constants in the constant pool (e.g., floating
point literal) from being placed in the mergeable constant sections?
We want to keep the const arrays declared in the program (s_dashArraySize1)
out of the mergeable constant sections, but don't mind placing constants
in the constant pool or constant arrays that the compiler defines, such
as switch.table and
