From 73e1c4a0309d3c81ad21f2c769d33222f6615abb Mon Sep 17 00:00:00 2001 From: George Rimar Date: Fri, 22 Mar 2019 10:24:37 +0000 Subject: [llvm-objcopy] - Implement replaceSectionReferences for GroupSection class. Currently, llvm-objcopy incorrectly handles compression and decompression of the sections from COMDAT groups, because we do not implement the replaceSectionReferences for this type of the sections. The patch does that.
