SOURCE BUG Duration: 46s

Subject

- rerun gcse pass after reload, enable whole-program iff we are not building the lib (due to bug in gcc; see comment.) I would have run the testsuite to check if everything is still behaving, but unfortunately i cannot run the testsuite anymore: it just sits there and does nothing even with a pris

SOURCE BUG

This commit was genuinely broken at the time (not related to our build system): scripts/config/mkconfigs.c (2005-08-01 - 2006-10-05 arasi) uretilen bbconfigopts.h icine .config satirlarini kacissiz, ham newline'larla gömüyordu - gecerli C degildi, busybox'un kendi bb_mkdep araci bile parse edemiyordu (7d219aab7 ile duzeltildi, mkconfigs shell scripte cevrildi)

→ Bu hatanin tam hikayesini ve duzeltme diffini gor
