GCC upstream have not release x.y.1 (since 5.1.0 release). x.y.1 is just "some commit between x.y.0 and x.(y+1).0". And distros may apply some their own modifications unknown by upstream. For example, Ubuntu is modifying their GCC code to enable -fPIE by default. The modifications (in .patch or .diff files) or modified GCC source tree should be available somewhere on the website of the distro. -- Xi Ruoyao <xry111@xxxxxxxxxxxxxxxx> School of Aerospace Science and Technology, Xidian University
