* Sync up with NetBSD libexecinfo changes 2014-2019Conrad Meyer2019-10-261-6/+38
| | | | | | | | | | | | | | | | | Drop portions that are unlit or redundant with llvm-libunwind: builtin.c, unwind.h, and unwind_arm_ehabi_stub.c. This code should now work with -fPIE binaries, should we choose to build any that way. When backtrace() array is full, signal an error so the underlying Itanium-style C++ exception handling library (llvm-libunwind) knows to stop tracing instead of continuing. (It should stop on its own when it finishes unwinding, so this is mostly an extra seatbelt against an infinite loop bug in the unwinder.) Notes: svn path=/head/; revision=354112
* Update to 2013-08-29 NetBSD libexecinfo snapshotEd Maste2013-08-291-3/+3
| | | | | | | | This adds my patch to use the kern.proc.pathname sysctl instead of relying on procfs(5). Notes: svn path=/head/; revision=255033
