|
# This test checks the "auto importing direct from a dll" functionality,
|
|
# which dramatically reduces the linking time for big libraries and applications
|
|
# by skipping creating/using import libraries. Instead it links directly to the
|
|
# related dll or to a symlinked dll for replacing regular import libraries.
|
|
#
|
|
# The test has 4 stages:
|
|
#
|
|
# 1. compile and link a test dll exporting some text and data symbols and a
|
|
# standard import library
|
|
#
|
|
# 2. create a symbolic link to this dll to simulate a replaced import library.
|
|
#
|
|
# 3. compile and link a client application with the standard import library.
|
|
# This should produce no errors.
|
|
#
|
|
# 4. compile and link a client application with the created dll.
|
|
# This should also produce no errors.
|
|
#
|
|
# 5. compile and link a client application using the "import library".
|
|
# This should also produce no errors.
|
|
#
|
|
# 6. compile and link a client application with auto-import disabled.
|
|
# This should produce a linking error.
|
|
|
|
# This test can only be run if ld generates native executables.
