# Tests for the special target .END in dependency declarations,
|
|
# which is run after making the desired targets.
|
|
#
|
|
# This test is very similar to deptgt-end.mk, except for the -j option.
|
|
# This option enables parallel mode, in which the code from job.c partially
|
|
# replaces the code from compat.c.
|
|
#
|
|
# Before 2020-08-22, this test crashed with a null pointer dereference.
|
|
# Before 2020-09-23, this test crashed with an assertion failure.

# The deferred commands are run in the order '.END .BEGIN all'.
|
|
# This may be unexpected at first since the natural order would be

# '.BEGIN all .END', but it is implemented correctly.
|
|
#
|
|
# At the point where the commands of a node with deferred commands are run,
|
|
# the deferred commands are appended to the commands of the .END node.
|
|
# This happens in Compat_RunCommand, and to prevent an endless loop, the
|
|
# deferred commands of the .END node itself are not appended to itself.
|
|
# Instead, the deferred commands of the .END node are run as if they were
|
|
# immediate commands.
