+* The .type pseudo-op now accepts a type of STT_IFUNC which can be used to
+ indicate that if the symbol is the target of a relocation, its value should
+ not be used. Instead the function should be invoked and its result used as
+ the value.

Changes in 2.19:
* New pseudo op .cfi_val_encoded_addr, to record constant addresses in unwind
