The objections I raised in:
https://sourceware.org/pipermail/gdb-patches/2020-April/167372.html
I think mostly apply to this revision too. So this is still not
approved.
The primary objection is (miss-)treatment of range endings and empty
ranges. You've expressed your position in other mail, so I wont try
to repeat you for fear of straw-manning your position. But for me any
solution would need to acknowledge that this is a work around for bugs
in the DWARF generated by specific versions of GCC, and weren't
present in much older versions of GCC, and might not be present in
newer versions of GCC, nor might these bugs be present in other
producers of DWARF.
In better news, I think my objection related to the lack of use of
std::vector would be easy enough to work around. This patch should
absolutely use std::vector, but a later patch can introduce
gdb::vector.
For those compilers where the performance of std::vector is good
enough, we make gdb::vector an alias for std::vector. For those
compiler where you are aware of a performance problem with
std::vector, then make gdb::vector a completely new, API compatible
implementation of std::vector. Heck, GCC code is copyright assigned
to FSF, so if GCC's std::vector is good enough you could just copy the
implementation from there.
Thanks,
Andrew
