Mike Haboustak	ee167c650e	[SV 28456] Don't override $< when no default rule has been defined ... The check for matching a file's command to the default rule's command does not account for null. If no .DEFAULT is defined a rule with no recipe has it's $< variable set to the value of $@. This breaks second expansion, particularly when used with pattern rules. * src/commands.c [set_file_variables]: Check that cmds is set * tests/scripts/features/se_explicit: Test case * tests/scripts/features/se_implicit: Test case Copyright-paperwork-exempt: yes	2019-07-13 11:47:26 -04:00
Paul Smith	fd30db1290	[SV 31155] Parse order-only tokens in second expansion results.	2013-09-22 17:10:35 -04:00
Paul Smith	5601726151	Keep a local count of the max dependency list size. ... This global variable could be modified during recursion so keep our own local copy to compare against.	2013-07-09 19:14:40 -04:00
Paul Smith	d65b267e4a	- Fix broken handling of order-only prereqs in secondary expansion ... of implicit rules. - Fix leaked memory when dealing with implicit rule chains that have file variables or pattern variables.	2009-09-24 20:59:22 +00:00
Paul Smith	0afbbf8595	- Rework secondary expansion so we only defer it if there's a possibility ... it might be needed: for most situations we parse prereqs immediately as we used to. Reduces memory usage. - Fixes Savannah bug #18622.	2009-09-24 02:41:44 +00:00
