[LLVMdev] Adding custom pragma's for generating particular LLVM IR
Hi ML readers,
I would first apology if this was already addressed on this ML, but I
didn't find information on this topic.
I would like to add custom pragma's that generate particular LLVM IR.
Here is an example:
int a, b;
/* ... */
#pragma mypragma shared(a, b)
