Series | Fix sparc64 build with GCC 9 [committed] | expand |
From: Joseph Myers <joseph@codesourcery.com> Date: Tue, 13 Nov 2018 00:27:41 +0000 > Similar to the x86_64 and armv7 build issues, glibc fails to build for > sparc64 with current mainline GCC because of aliases declared in the > course of defining IFUNCs, which copy their attributes from a header > declaration, ending up with fewer attributes than the (built-in) > string function they alias. This patch fixes the issue similarly to > the fixes for those other architectures. > > Tested with build-many-glibcs.py compilers build for > sparc64-linux-gnu. Committed. Thank you.
