Yes, I've actually already started to work with this lang-hook so we
can master the DWARF information output for Ada array types (very
useful!). However, it does not solve the issue of knowing what DWARF
operations to output in order to compute the bounds of VLAs
*without* descriptors. (see the end of my 05/14/2014 mail)
You still build some trees in that langhook that describe the bounds etc.
and dwarf2out.c just transforms those trees into DWARF4 expression opcodes.
Absolutely. In my use case, dwarf2out.c currently doesn't know how to
translate trees from the Ada frontend into DWARF opcodes. I started this
thread in order to know how it should do so.
