# Issues from PR 49086
|
|
|
|
# Issue 3: single suffix rules remain active after .SUFFIXES is cleared
|
|
#
|
|
# There's a rule for issue3.a, but .a is no longer a known suffix when
|
|
# targets are being made, so issue3 should not get made.
|
|
all: issue3
|
|
|
|
# Issue 4: suffix rules do not become regular rules when .SUFFIXES is cleared
|
|
#
|
|
# When the rules were encountered, .a and .b were known suffices, but later
|
|
# on they were forgotten. These should get created as regular targets.
|
|
all: .a .a.b .b.a
|
|
|
|
# Issue 5: adding more suffixes does not make existing rules into suffix rules
|
|
#
|
|
# When the targets .c.d, .d.c, .d, .d.e, and .e.d were encountered, only .a,
|
|
# .b and .c were known suffixes, so all of them were regular rules. Later
|
|
# rest of the suffixes were made known, so they should all be suffix
|
|
# transformation rules.
|
|
all: issue5a.d issue5b.c issue5c issue5d.e issue5e.d
|
|
|
|
# Issue 6: transformation search can end up in an infinite loop
|
|
#
|
|
# There is no file or target from which issue6.f could be made from so
|
|
# this should fail. The bug was that because rules .e.f, .d.e and .e.d
|
|
# exist, make would try to make .f from .e and then infinitely try
|
|
# to do .e from .d and vice versa.
|
|
all: issue6.f
|
|
|
|
# Issue 10: explicit dependencies affect transformation rule selection
|
|
#
|
|
# If issue10.e is wanted and both issue10.d and issue10.f are available,
|
|
# make should choose the .d.e rule, because .d is before .f in .SUFFIXES.
|
|
# The bug was that if issue10.d had an explicit dependency on issue10.f,
|
|
# it would choose .f.e instead.
|
|
all: issue10.e
|
|
|
|
# Issue 11: sources from transformation rules are expanded incorrectly
|
|
#
|
|
# issue11.j should depend on issue11.i and issue11.second and issue11.i
|
|
# should depend on issue11.h and issue11.first. The bug was that
|
|
# the dynamic sources were expanded before ${.PREFIX} and ${.TARGET} were
|
|
# available, so they would have expanded to a null string.
|
|
all: issue11.j
|
|
|
|
# we need to clean for repeatable results
