     1# Regression test for issue #48557.
     2# Since builds in module mode do not support relative imports at all, the build
     3# ID for (and other contents of) a binary built with -trimpath in module mode
     4# should not depend on its working directory, even if the binary is specified as
     5# a list of relative source files.
     6
     7[short] skip  # links and runs binaries

    13# When we build a binary in module mode with -trimpath, the -D flag (for the
    14# "local import prefix") should not be passed to it.
