These should get created as regular targets. 15all: .a .a.b .b.a 16 17# Issue 5: adding more suffixes does not make existing rules into suffix rules 18# 19# When the targets .c.d, .d.c, .d, .d.e, and .e.d were encountered, only .a, 20# .b and .c were known suffixes, so all of them were regular rules. Later 21# rest of the suffixes were made known, so they should all be suffix 22# transformation rules. 23all: issue5a.d issue5b.c issue5c issue5d.e issue5e.d 24 25# Issue 6: transformation search can end up in an infinite loop 26# 27# There is no file or target from which issue6.f could be made from so 28# this should fail. The bug was that because rules .e.f, .d.e and .e.d 29# exist, make would try to make .f from .e and then infinitely try 30# to do .e from .d and vice versa. 31all: issue6.f 32 33# Issue 10: explicit dependencies affect transformation rule selection 34# 35# If issue10.e is wanted and both issue10.d and issue10.f are available, 36# make should choose the .d.e rule, because .d is before .f in .SUFFIXES. 37# The bug was that if issue10.d had an explicit dependency on issue10.f, 38# it would choose .f.e instead. 39all: issue10.e 40 41# Issue 11: sources from transformation rules are expanded incorrectly 42# 43# issue11.j should depend on issue11.i and issue11.second and issue11.i 44# should depend on issue11.h and issue11.first. The bug was that 45# the dynamic sources were expanded before ${.PREFIX} and ${.TARGET} were 46# available, so they would have expanded to a null string. 47all: issue11.j 48 49# we need to clean for repeatable results 50.BEGIN: clean 51clean: 52 @rm -f issue* .[ab]* 53 54.SUFFIXES: .a .b .c 55 56.a .a.b .b.a: 57 @echo 'There should be no text after the colon: ${.IMPSRC}' 58 touch ${.TARGET} 59 60.c.d .d.c .d .d.e .e.d: 61 @echo 'first set' 62 cp ${.IMPSRC} ${.TARGET} 63 64.SUFFIXES: 65.SUFFIXES: .c .d .e .f .g 66 67.e .e.f .f.e: 68 @echo 'second set' 69 cp ${.IMPSRC} ${.TARGET} 70 71issue3.a: 72 @echo 'There is a bug if you see this.' 73 touch ${.TARGET} 74 75issue5a.c issue5b.d issue5c.d issue5d.d issue5e.e issue10.d issue10.f: 76 touch ${.TARGET} 77 78.SUFFIXES: .h .i .j 79 80.h.i: ${.PREFIX}.first 81 @echo '.ALLSRC: ${.ALLSRC}' 82 cp ${.IMPSRC} ${.TARGET} 83 84.i.j: ${.PREFIX}.second 85 @echo '.ALLSRC: ${.ALLSRC}' 86 cp ${.IMPSRC} ${.TARGET} 87 88issue11.h issue11.first issue11.second: 89 touch ${.TARGET} 90
