The attached patch implements support for ARM EABI unwinding and c++
exception handling. The original patch (against csl-arm-branch) can be
found here:

Please make sure that each new function definition has a comment above it describing what the function does and the significance of the arguments and return value if any. Some functions (e.g. in config/arm/pr-support.c) have no comments, others say nothing about the parameters.

I think the documentation should refer to @code{true} and @code{false}
rather than @code{TRUE} and @code{FALSE}.  tm.texi only refers to the
lowercase versions at present.  The code has both, though I think we
should prefer the C99-and-C++-type lowercase versions for new code.

Updated patch attached addresses these issues. No functional changes.

The comment for output_ttype should describe the TT_FORMAT and TT_FORMAT_SIZE nodes and TARGET_UNWIND_TABLES_DEFAULT needs an entry in tm.texi.

The middle-end changes look well segregated. The ARM changes are within your purview. The libstdc++ changes also look clean, and there have been no objections.

Therefore, the patch is OK for mainline. However, as a courtesy, please do not check the patch in for 48 hours. That will give the EH and/or libstdc++ people a last chance to object.
