# Test that mimics a use case of -n to produce a kernel mapped shared-object
|
|
# in a non paged context. We specifically want to test:
|
|
# - We can allocate the headers into the first program header (via PHDRS)
|
|
# typically -n does not allocate headers.
|
|
# - The alignment of the .text section is not page aligned.
