--- Comment #2 from dodji at redhat dot com ---
Hello,
I could reproduce the issue, thanks for reporting the issue.
This appears to be one these embarrassing quadratic behaviour that the current
type canonicalization process has :-(
I tried the work-in-progress type-hashing branch on the binary and here is what
I am getting:
$ time ~/git/libabigail/hash-types/build/tools/abidw -d usr/lib/debug
usr/lib64/libgs.so.9.27 > libgs.so.9.27.hashed.abi
real 0m45,004s
user 0m44,734s
sys 0m0,142s
$
In other words, the current type-hashing work on the branch
https://sourceware.org/git/?p=libabigail.git;a=shortlog;h=refs/heads/users/dodji/hash-types
seems to address precisely this kind of issues.
I'll look into this a bit more to see if I can find a work-around before I am
done with the type-hashing work. But we might as well wait for type-hashing
work to land.
