# Assemble a .s file, then run some utility on it and check the output.
-#
+#
# There should be an assembly language file named FILE.s in the test
# suite directory, and a pattern file called FILE.d. `run_dump_test'
# will assemble FILE.s, run some tool like `objdump', `objcopy', or
# flags to pass to the assembler, the program to run to dump the
# assembler's output, and the options it wants. The option lines have
# the syntax:
-#
+#
# # OPTION: VALUE
-#
+#
# OPTION is the name of some option, like "name" or "objdump", and
# VALUE is OPTION's value. The valid options are described below.
# Whitespace is ignored everywhere, except within VALUE. The option
# (hmm, not great for error detection).
#
# The interesting options are:
-#
+#
# name: TEST-NAME
# The name of this test, passed to DejaGNU's `pass' and `fail'
# commands. If omitted, this defaults to FILE, the root of the
# .s and .d files' names.
-#
+#
# as: FLAGS
# When assembling, pass FLAGS to the assembler.
# If assembling several files, you can pass different assembler
# Link assembled files using FLAGS, in the order of the "source"
# directives, when using multiple files.
#
+# objcopy_linked_file: FLAGS
+# Run objcopy on the linked file with the specified flags.
+# This lets you transform the linked file using objcopy, before the
+# result is analyzed by an analyzer program specified below (which
+# may in turn *also* be objcopy).
+#
# PROG: PROGRAM-NAME
# The name of the program to run to analyze the .o file produced
# by the assembler or the linker output. This can be omitted;
# objcopy: FLAGS
# Use the specified program to analyze the assembler or linker
# output file, and pass it FLAGS, in addition to the output name.
+# Note that they are run with LC_ALL=C in the environment to give
+# consistent sorting of symbols.
#
# source: SOURCE [FLAGS]
# Assemble the file SOURCE.s using the flags in the "as" directive
# to pass. The PROG, objdump, nm and objcopy options have no
# meaning and need not supplied if this is present.
#
+# warning: REGEX
+# Expect a linker warning matching REGEX. It is an error to issue
+# both "error" and "warning".
+#
# Each option may occur at most once unless otherwise mentioned.
#
# After the option lines come regexp lines. `run_dump_test' calls
# `regexp_diff' to compare the output of the dumping tool against the
# regexps in FILE.d. `regexp_diff' is defined later in this file; see
# further comments there.
