# Check that scripts using the "=" sysroot-prefix work, for both
# toolchains with and without --sysroot support.

# We test this by emitting archives into a subdirectory and expect
# constructs such as GROUP and AS_NEEDED (the only two constructs
# actually tested) to find them (or not); both quoted and unquoted
# paths, with different prefixes on the path and with --sysroot
# present or not, with different arguments.

# Find out if the linker supports sysroot; if it was configured
# "--with-sysroot X" where X is a non-empty string.

# the tests prepend sysroot to the current directory and on most
# common systems "//dir/path" is handled as "/dir/path".

# Entries in the array-tables:
# 0: Testtype; an inclusive bitmask indicating that the test should run on a
# build configured for: 1: non-sysroot, 2: sysroot != "/", 4: sysroot == "/".
# 1: Description, forming part of the dejagnu test-name.
# 2: Replacement for @p@.
# 3: Option to pass to linker (usually something with --sysroot).
# 4: Message substring; a substring to match against the error message
# if an error is expected, or empty if no error is expected.
#
# If the replacement or option contains @cwd@, that'll be replaced by
# "$base_dir/tmpdir", the full path to the location of the script
# (with the actual files in the "sysroot" subdirectory).  If the
# description contains @cwd@, that will be replaced by "<CWD>".
