Hi, With my shiny new gcc 5.2 toy, I thought I'd test how its LTO worked for bb, and share the numbers. There were a few hundred new warnings, one parenthesis in ash, and all the rest about strict aliasing, mainly in minix and top.
All on x86_64, defconfig with sync_fancy and ubi* disabled. busybox git 68acc0f8353 gcc 4.2.2: 849405 bytes 100% gcc 5.2.0: 829369 bytes 97.6% LTO 5.2.0: 828209 bytes 97.5% So, the current best LTO saved a bit over a kb, that's pretty well done for bb's manual tuning. - Lauri -- http://www.fastmail.com - Email service worth paying for.
