17 # Test for PR 307: depcomp with depmode=dashmstdout libtool race condition
18 # Report from Laurent Morichetti.
19 # (Also exercises check_LTLIBRARIES.)
22 # The dashmstdout depmode calls libtool in parallel to generate the
23 # dependencies (with -M flag) and to build the objfile (both have
24 # --mode=compile and -o).
25 # The process with 'libtool --mode=compile .* -M' can corrupt the objfile
26 # as none is generated by the compiler. Since --mode=compile and -o are
27 # set libtool assumes that a objfile should be generated and will execute
28 # invalid $mv & $LN_S.
31 # Now 'depcomp' never compute dependencies in the background, as this can
32 # cause races with libtool. Compute the dependencies after the actual
35 required
