Denys Vlasenko	eb17b6f6c9	ash: eval: Return status in eval functions ... Backported from dash: eval: Return status in eval functions The exit status is currently clobbered too early for case statements and loops. This patch fixes it by making the eval functions return the current exit status and setting them in one place -- evaltree. Harald van Dijk pointed out a number of bugs in the original patch. function old new delta evalcommand 1226 1242 +16 cmdloop 383 398 +15 evalfor 223 227 +4 evalcase 271 275 +4 localcmd 348 350 +2 evaltreenr 927 928 +1 evaltree 927 928 +1 evalsubshell 150 151 +1 evalpipe 356 357 +1 parse_command 1585 1584 -1 evalloop 177 164 -13 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 9/2 up/down: 45/-14) Total: 31 bytes Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>	2016-09-28 19:41:57 +02:00
