From 3737c0363050b5f2f3a9ba5d4daac6881069d369 Mon Sep 17 00:00:00 2001 From: Bernhard Reutner-Fischer Date: Fri, 28 Apr 2006 20:02:29 +0000 Subject: [PATCH] - 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 pristine checkout and an old gcc. srcdir=/tmp/busybox/testsuite /tmp/busybox/testsuite/runtest PASS: Applet order FAIL: Common typos PASS: Obsolete function usage PASS: Obsolete function usage make[1]: *** [check] Interrupt make: *** [check] Interrupt I've just corrected that wrong double-printing.
