Hi I use BlockAddress to get the address of BasicBlock , and I use GlobalVariable 's getInitializer() to pass the address of BasicBlock to the global variable of my own program and then I print it out. But , I found that BlockAddress is not always correct. For example, some function's rsp (stack pointer) or other register is maintained by caller, so it would be like:

John, I'm still not sure what you're talking about, I have included the assembly output from two compilations, one with a user explicit catch-all, one with only an implicit cleanup, the DWARF Action Table and Types Table are absolutely identical, as are the indexes used to reference the Action Table from the region maps. -Peter Lawrence.
