Re: [Libunwind-devel] [PATCH] Add an option to have start_ip_offset be relative to start_ip

[Keno Fischer]

Bump, does this patch look reasonable?

By default, the start_ip_offset in libunwind's table_entry struct is

relative to the unw_dyn_info_t's segbase. This presents a problem

for us in conjunction with using LLVM's MCJIT because it likes to

spread text sections and the corresponding eh_frame sections quite

far apart. This represents my attempt to support this use case in the

simplest manner that is backwards compatible, by adding a new format

kind (UNW_INFO_FORMAT_REMOTE_TABLE2) that indicates that the

`start_ip_offset` should be interpreted as relative to `start_ip`

rather than segbase.
