I don't set -ffunction-sections explicitly but it seems to be used when I look at the .cmd files. The build command is nothing fancy, I just set ARCH=mips CROSS_COMPILE=mips64-unknown-linux-gnuabin32- and build with make -j24.Thanks for reporting this issue! I'm assuming your kernel build enables dead code elimination and uses the --ffunction-sections compiler flag. Without this patch, all the functions -- I think there are only .text.unlikely.* and .text.* are grouped together in the final vmlinux. This patch modifies the linker script to place .text.unlikely.* functions before .text.* functions. I've examined arch/mips/kernel/vmlinux.lds.S, and haven't found any obvious issue. Can you send me the following? (1) the kernel build command (2) System.map without the patch (3) System.map with the patch Best regards, -Rong
I've attached the System.map, built on next-20241111 as well as it with this series reverted.
