Subject: More efficient AbbrevDecl handling (#212)
X-Git-Tag: v0.26~28
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ee37f4c569fa17df9041678c04bdb44b3f1fd38a;p=pyelftools.git

More efficient AbbrevDecl handling (#212)

Create all the AbbrevDecl objects during parsing and later return
references to them - this gives a small performance gain.
