925 # EXPECT_ARGUMENTS will be fed to expect in addition to the standard

977 # ...", all being implicitly appended to that list. These are always
978 # expected from $gdb_spawn_id. IOW, callers do not need to worry
979 # about resetting "-i" back to $gdb_spawn_id explicitly.
981 # In EXPECT_ARGUMENTS we can use a -wrap pattern flag, that wraps the regexp
982 # pattern as gdb_test wraps its message argument.

' that is available in gdb_test is also
992 # supported in gdb_test_multiple when -wrap is used.
994 # In EXPECT_ARGUMENTS, a pattern flag -early can be used. It makes sure the

1066 # Expect does something very strange when it receives a single braced

1068 # This means that { "[ab]" } is evaluated as "[ab]", but { "\[ab\]" } is
1069 # evaluated as "\[ab\]". But that's not how TCL normally works
; inside a
1070 # double
-quoted list item
, "\[ab\]" is just a long way of representing
1071 #
"[ab]", because the backslashes will be removed by lindex.
1073 # Unfortunately
, there appears to be no easy way to duplicate the splitting
1074 # that expect will
do from within TCL. And many places make use of the
1075 #
"\[0-9\]" construct, so we need to support that; and some places make use
1076 # of the
"[func]" construct, so we need to support that too. In order to
1077 #
get this right we have to substitute quoted list elements differently
1078 # from braced list elements.
1080 # We
do this roughly the same way that Expect does it. We have to use two
1081 # lists
, because
if we leave unquoted newlines in the
argument to uplevel
1082 # they
'll be treated as command separators, and if we escape newlines
1083 # we mangle newlines inside of command blocks. This assumes that the

5176 # - shlib_load: Link with appropriate libraries to allow the test to
5177 # dynamically load libraries at runtime. For example, on Linux, this adds
5178 # -ldl so that the test can use dlopen.
5179 # - nowarnings: Inhibit all compiler warnings.
5180 # - pie: Force creation of PIE executables.
5181 # - nopie: Prevent creation of PIE executables.
5182 # - macros: Add the required compiler flag to include macro information in
5184 # - text_segment=addr: Tell the linker to place the text segment at ADDR.
5185 # - build-id: Ensure the final binary includes a build-id.
5186 # - column-info/no-column-info: Enable/Disable generation of column table
