there is also unwind-arm-common.inc, which is included by ./config/arm/unwind-arm.h and ./config/c6x/unwind-c6x.h, so yes, not many, only few. > For ia64-elf ISTM this header should be coming from newlib but I don't want to use newlib or glibc, I just wanted to see if my other patch breaks something.
