The internal structure of FunctionData. This makes sure that changes to the fields of FunctionData either get automatically captured on the llvm side, or force a manual corresponding update.
Declared in <llvm/ProfileData/CtxInstrContextNode.h>
#define CTXPROF_FUNCTION_DATA(PTRDECL, CONTEXT_PTR, VOLATILE_PTRDECL, MUTEXDECL)
The macro arguments (see CtxInstrProfiling.h for example):
PTRDECL is a macro taking 2 parameters: a type and the name of the field. The field is a pointer of that type;
VOLATILE_PTRDECL is the same as above, but for volatile pointers;
MUTEXDECL takes one parameter, the name of a field that is a mutex.
