From e50d23c30cd8259941b25e336b11cd96e4f6cd31 Mon Sep 17 00:00:00 2001 From: Hongxu Jia Date: Mon, 28 Mar 2016 04:18:46 -0400 Subject: gcc-5.3/gcc-4.9: -fdebug-prefix-map support to remap relative path For relative path in DWARF, -fdebug-prefix-map could not remap it, so translate to real path before mapping.
