Subject: bsdtar: remove tar_i64toa()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=17fc2be73a7722ffd55cdfbf86f2549fe5a7c9a6;p=thirdparty%2Flibarchive.git

bsdtar: remove tar_i64toa()

Format integer values directly at each call site and remove the custom
integer formatter.

This handles the full signed integer range and preserves unsigned byte
counters.
