Hello, On top of the correction for fallouts proposed in
https://gcc.gnu.org/ml/gcc-patches/2017-08/msg00271.html the attached patch is needed to support targets still resorting to DWARF2 unwinding on ARM, such as VxWorks6 (VxWorks7 has moved to ARM EH). Tested by verifying that a build with mainline sources for arm-wrs-vxworks proceeds to completion, that a similar gcc-7 based compiler builds fine as well and passes Ada ACATS, which confirms proper operation of the DWARF2 based exceptions. OK to commit ? Thanks in advance for your feedback, Olivier 2017-08-03 Olivier Hainque <hain...@adacore.com> * common/config/arm/arm-common.c (arm_except_unwind_info): Handle DWARF2_UNWIND_INFO.
