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.

ARM: can build with llvm, switch to EABI . bitcode fixes . switch to compiler-rt instead of netbsd libc functions or libgcc for support functions for both x86 and arm . minor build fixes . allow build with llvm without crossbuilding llvm itself . can now build minix/arm using llvm and eabi - without C++ support for now (hence crossbuilding llvm itself is turned off for minix/arm) Change-Id: If5c44ef766f5b4fc4394d4586ecc289927a0d6eb
