Hello there!
I used to play with the compiler options of GCC. These days I was recompiling
the packages of my machine using the PKGBUILD files provided by the Arch
community and I just found a few packages became bigger when using the flto=4
parameter.
0s 0s flto 02 02 flto
jansson 142,00 KiB 419,00 KiB 163,00 KiB 433,00 KiB

zlib 293,00 KiB 717,00 KiB 327,00 KiB 752,00 KiB
