build: use thin archives rather than incremental linking

2018-03-01T02:28:39+00:00

This changes to build system to use thin archives rather than incremental linking for built-in.o, similar to recent change to Linux. built-in.o is renamed to built-in.a, and is created as a thin archive with no index, for speed and size. All built-in.a are aggregated into a skiboot.tmp.a which is a thin archive built with an index, making it suitable or linking. This is input into the final link. The advantags of build size and linker code placement flexibility are not as great with skiboot as a bigger project like Linux, but it's a conceptually better way to build, and is more compatible with link time optimisation in toolchains which might be interesting for skiboot particularly for size reductions. Size of build tree before this patch is 34.4MB, afterwards 23.1MB. Signed-off-by: Nicholas Piggin Signed-off-by: Stewart Smith

mktime: fix off-by-one error calling days_in_month

2017-08-24T02:59:15+00:00

From auditing all the mktime() users, there seems to be only a *very* small window around new years day where we could possibly return incorrect data to the OS, and even then, there would have to be FSP reset/reload on FSP machines. I don't *think* there's an opportunity on other machines. Signed-off-by: Stewart Smith
