-------------------- Start of forwarded message -------------------- From: Allan McRae <[email protected]> Date: Mon, 27 Jul 2015 14:15:30 +1000 Subject: [arch-dev-public] CFLAGS We have a couple of bugs open about our CFLAGS. 1) https://bugs.archlinux.org/task/44361 -Remove the no-op --param=ssp-buffer-size=4 switch from CFLAGS Since we moved from -fstack-protector to -fstack-protector-strong, this paramater is unused and can be removed. 2) https://bugs.archlinux.org/task/44362 - Add -fstack-check Read more about this here: https://gcc.gnu.org/onlinedocs/gccint/Stack-Checking.html This is essentially a no-op for most code, so should have no real performance hit. I can not find any benchmarks to demonstrate that though. This would mean: CFLAGS="-march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fstack-check" Opinions?
