Dan Albert	e5f15210fb	Add missing include to a test case. Some platforms get size_t defined transitively by another include, but Android does not. llvm-svn: 216738	2014-08-29 16:09:32 +00:00
Dan Albert	2c012d495d	Make _Unwind_Backtrace() work on ARM. Summary: Since the personality functions do the actual unwinding on ARM, and will also stop unwinding when they encounter a handler, we invoke _Unwind_VRS_Interpret() directly form _Unwind_Backtrace(). To simplify, the logic for decoding an EHT is moved out of unwindOneFrame() and into its own function, decode_eht_entry(). Unlike unwindOneFrame(), which could only handle ARM's compact personality function entries (section 6.3) decode_eht_entry() can handle the generic entries (section 6.2).

Add missing include to a test case.

Some platforms get size_t defined transitively by another include, but
Android does not.

Make _Unwind_Backtrace() work on ARM.

Summary: Since the personality functions do the actual unwinding on ARM,
and will also stop unwinding when they encounter a handler, we invoke
_Unwind_VRS_Interpret() directly form _Unwind_Backtrace().

To simplify, the logic for decoding an EHT is moved out of
unwindOneFrame() and into its own function, decode_eht_entry(). Unlike
unwindOneFrame(), which could only handle ARM's compact personality
function entries (section 6.3) decode_eht_entry() can handle the generic
entries (section 6.2).
