new libunwind, updated to netbsd b1f513eedd existing libunwind used '0' in lsda_encoding as 'not present,' whereas that is a valid encoding and does occur and would be ignored. a missing encoding is actually 0xff. The commit that addresses this is: commit 8d4b51028d1a12b58d616f4b605254a877caafcf Author: joerg <joerg> Date: Tue Mar 11 23:52:17 2014 +0000 0 is a valid LSDA encoding and can be seen in statically linked programs. Initialize lsdaEncoding to DW_EH_PE_omit and check for that value to decide whether a value should be decoded. more bugfixes are necessary. this update is up to: commit b1f513eedd332426d88acbb118b6e9070966dcb9 Author: joerg <joerg> Date: Wed May 14 22:13:36 2014 +0000 Lazy VFP processing works a lot better if the functions contain a return instruction. 2014-05-12 15:17:14 +02:00			`# $NetBSD: Makefile.inc,v 1.5 2014/03/19 16:46:23 joerg Exp $`
