48# Symlink handling.
49# On POSIX, symlinks to the target can be created before the target exist,
50# and the target can depend on the symlink targets, so that building the
51# target ensures the symlinks exist.
52# However, symlinks didn't exist on Windows until recently, so there the
53# binary needs to be copied -- which requires it to exist. So the symlink step
54# needs to run after the target that creates the binary.
55# In the cmake build, this is done via a "postbuild" on the target, which just
56# tacks on "&& copy out.exe out2.exe" to the link command.
57# GN doesn't have a way to express postbuild commands.  It could probably be
58# emulated by having the link command in the toolchain be a wrapper script that
59# reads a ".symlinks" file next to the target, and have an action write that
60# and make the target depend on that, but then every single link has to use the
61# wrapper (unless we do further acrobatics to use a different toolchain for
62# targets that need symlinks) even though most links don't need symlinks.
63# Instead, have a top-level target for each target that needs symlinks, and
64# make that depend on the symlinks. Then the symlinks can depend on the
65# executable.  This has the effect that `ninja lld` builds lld and then creates
66# symlinks (via this target), while `ninja bin/lld` only builds lld and doesn't
67# update symlinks (in particular, on Windows it doesn't copy the new lld to its
68# new locations).
69# That seems simpler, more explicit, and good enough.
