Dmitry Goncharov 33468b3f31 [SV 60297] Add .NOTINTERMEDIATE special target ... Support a new special target, .NOTINTERMEDIATE. Any file or pattern prerequisite of this target will never be considered intermediate. This differs from .SECONDARY in that .SECONDARY files won't be deleted but they will still not be built if they are missing. .NOTINTERMEDIATE files are treated the same way as a target which is explicitly mentioned in the makefile. This is mostly useful with patterns; obviously mentioning a target explicitly here is enough in and of itself to make something not intermediate. Some adjustments made by psmith@gnu.org * NEWS: Announce the new feature. * doc/make.texi (Special Targets): Document .NOTINTERMEDIATE. (Chained Rules): Describe how to use .NOTINTERMEDIATE. * src/main.c (main): Add "notintermediate" to the .FEATURES variable. * src/filedef.h (struct file): Add "notintermediate" flag. * src/file.c (no_intermediates): Mark global .NOTINTERMEDIATE. (snap_file): Support .NOTINTERMEDIATE special target. Throw an error if the same target is marked both .NOTINTERMEDIATE and .SECONDARY or .INTERMEDIATE. (rehash_file): Merge intermediate, notintermediate, secondary flags. (remove_intermediates): Check notintermediate flag before removing. (print_file): * src/implicit.c (pattern_search): Set notintermediate based on the pattern. * tests/scripts/targets/NOTINTERMEDIATE: Add a new test suite.		2021-07-25 17:15:38 -04:00
