From 176380fd113a97b09c99a5f7273725527823fa1b Mon Sep 17 00:00:00 2001 From: Jeff King Date: Thu, 24 Sep 2020 15:22:29 -0400 Subject: Revert "fast-export: use local array to store anonymized oid" This reverts commit f39ad38410da554af54966bf74fa0402355852ac. That commit was trying to silence a type-punning warning on older versions of gcc. However, its analysis was all wrong. I didn't notice that we _were_ in fact type-punning because there are two versions of put_be32(): one that uses casts and unaligned loads, and another that uses bitshifts. I looked at the latter, but on my platform we were defaulting to the former. However, as of the previous commit, we'll always use the bitshift version. So we can drop this hackery to avoid the warning, making the code slightly cleaner.
