Bug ID: 29360
Summary: Ada ranges emitting/reading/diffing are not supported
in libabigail
Product: libabigail
Version: unspecified
Status: NEW
Severity: enhancement
Priority: P2
Component: default
Assignee: dodji at redhat dot com
Reporter: dodji at redhat dot com
CC: libabigail at sourceware dot org
Target Milestone: ---
fedabipkgdiff --self-compare -a --from fc36 zlib-ada
Appears to be stuck. Upon closer look it appears that abipkgdiff is stuck in
an infinite loop:
build/tools/abipkgdiff --self-check --d1
/home/dodji/.cache/fedabipkgdiff/downloads/zlib-ada-debuginfo-1.4-0.30.20120830CVS.fc36.x86_64.rpm
/home/dodji/.cache/fedabipkgdiff/downloads/zlib-ada-1.4-0.30.20120830CVS.fc36.x86_64.rpm
.
Free form range types (range types that are not part of array types), used in
Ada are not fully supported by Libabigail.
What is not supported is their serilization in abixml, their de-serialization
from abixml and their comparison by the comparison engine.
I started a branch with that work, at
https://sourceware.org/git/?p=libabigail.git;a=shortlog;h=refs/heads/free-range-types.
What needs to be done is the support for diffing. Basically, creating a diff
type for range types, coming up with a compute_diff function that takes ranges
and returns the diff type for ranges and adding support for reporting the
changes carried by the range diff type.
This is a nice little feature to work on, IMHO.

--- Comment #1 from dodji at redhat dot com ---
It looks like this support for Ada ranges is now in.
At least from this patch:
ff8cba87 dwarf-reader: Support indirectly referenced subrange_type DIEs
I am thus closing this bug now.
