505# OPTION is the name of some option, like "name" or "objdump", and
506# VALUE is OPTION's value. The valid options are described below.
507# Whitespace is ignored everywhere, except within VALUE. The option
508# list ends with the first line that doesn't match the above syntax.
509# However, a line within the options that begins with a #, but doesn't
510# have a recognizable option name followed by a colon, is considered a
511# comment and entirely ignored.
512#
513# The optional EXTRA_OPTIONS argument to `run_dump_test' is a list of
514# two-element lists. The first element of each is an option name, and
515# the second additional arguments to be added on to the end of the
516# option list as given in FILE.d. (If omitted, no additional options
517# are added.)
518#
519# The interesting options are:
520#
521# name: TEST-NAME
522# The name of this test, passed to DejaGNU's `pass' and `fail'
523# commands. If omitted, this defaults to FILE, the root of the
524# .s and .d files' names.
525#
526# as: FLAGS
527# When assembling, pass FLAGS to the assembler.
528# If assembling several files, you can pass different assembler
529# options in the "source" directives. See below.

MM
530# Multiple instances of this directive tells run_dump_test to run the test
531# multiple times -- one time with each set of flags provided.
532# Each instance will run exactly as a file with a single "as" line, it is
533# not possible to condition any behaviour on which set of "as" flags is
534# used. That means that the "source" specific options are appended to
535# the "as" flags for their corresponding files, and any extra processing
536# (e.g. with "ld" and "objcopy") is repeated for each test.
8ffb70eb
AM
537#
538# ld: FLAGS
539# Link assembled files using FLAGS, in the order of the "source"
540# directives, when using multiple files.
541#
542# ld_after_inputfiles: FLAGS
543# Similar to "ld", but put FLAGS after all input files.
544#
545# objcopy_objects: FLAGS
546# Run objcopy with the specified flags after assembling any source
547# that has the special marker RUN_OBJCOPY in the source specific
548# flags.
549#
550# objcopy_linked_file: FLAGS
551# Run objcopy on the linked file with the specified flags.
552# This lets you transform the linked file using objcopy, before the
553# result is analyzed by an analyzer program specified below.
554#
555# PROG: PROGRAM-NAME
556# The name of a program under test, to run to modify or analyze the
557# .o file produced by the assembler. Recognised names are: ar,
558# elfedit, nm, objcopy, ranlib, strings, and strip.
559#
560# DUMPPROG: PROGRAM-NAME
561# The name of the program to run to analyze the file produced
562# by the assembler or the linker. This can be omitted;
563# run_dump_test will guess which program to run from which of
564# the flags options below is present.
565#
566# addr2line: FLAGS
567# nm: FLAGS
568# objdump: FLAGS
569# readelf: FLAGS
570# size: FLAGS
571# Use the specified program to analyze the output file, and pass it
572# FLAGS, in addition to the output name. Note that they are run
573# with LC_ALL=C in the environment to give consistent sorting of
574# symbols. If no FLAGS are needed then you can use:
575# DUMPPROG: [nm objdump readelf addr2line]
576# instead, or just pass a flag that happens to be the default.
577# If objdump is the dump tool and we're not dumping binary, nor
578# have run ld, then the standard section names (.text, .data and
579# .bss) are replaced by target ones if any (eg. rx-elf uses "P"
580# instead of .text). The substition is done for both the
581# objdump options (eg: "-j .text" is replaced by "-j P") and the
582# reference file.
583#
584# source: SOURCE [FLAGS]
585# Assemble the file SOURCE.s using the flags in the "as" directive
586# and the (optional) FLAGS. If omitted, the source defaults to
587# FILE.s.
588# This is useful if several .d files want to share a .s file.
589# More than one "source" directive can be given, which is useful
590# when testing linking.
591#
592# dump: DUMP
593# Match against DUMP.d. If omitted, this defaults to FILE.d. This
594# is useful if several .d files differ by options only. Options are
595# always read from FILE.d.
596#
597# target: GLOB|PROC ...
598# Run this test only on a specified list of targets. More precisely,
599# in the space-separated list each glob is passed to "istarget" and
600# each proc is called as a TCL procedure. List items are interpreted
601# such that procs are denoted by surrounding square brackets, and any
602# other items are consired globs. If the call evaluates true for any
603# of them, the test will be run, otherwise it will be marked
604# unsupported.
605#
606# notarget: GLOB|PROC ...
607# Do not run this test on a specified list of targets. Again, each
608# glob in the space-separated list is passed to "istarget" and each
609# proc is called as a TCL procedure, and the test is run if it
610# evaluates *false* for *all* of them. Otherwise it will be marked
611# unsupported.
612#
613# alltargets: GLOB|PROC ...
614# Run this test on a specified list of targets. Again, each
615# glob in the space-separated list is passed to "istarget" and each
616# proc is called as a TCL procedure, and the test is run if it
617# evaluates *true* for *all* of them. Otherwise it will be marked
618# unsupported.
619#
620# skip: GLOB|PROC ...
621# anyskip: GLOB|PROC ...
622# noskip: GLOB|PROC ...
623# These are exactly the same as "notarget", "alltargets" and
624# "target" respectively, except that they do nothing at all if the
625# check fails. They should only be used in groups, to construct a
626# single test which is run on all targets but with variant options
627# or expected output on some targets. (For example, see
628# gas/arm/inst.d and gas/arm/wince_inst.d.)
629#
630# xfail: GLOB|PROC ...
631# Run this test and it is is expected to fail on a specified list
632# of targets.
633#
634# error: REGEX
635# An error with message matching REGEX must be emitted for the test
636# to pass. The DUMPPROG, addr2line, nm, objdump, readelf and size
637# options have no meaning and need not supplied if this is present.
638# Multiple "error" directives append to the expected error message.
639#
640# error_output: FILE
641# Means the same as 'error', except the regular expression lines
642# are contains in FILE.
643#
644# warning: REGEX
645# Expect a warning matching REGEX. It is an error to issue
646# both "error" and "warning". Multiple "warning" directives
647# append to the expected warning message.
648#
649# warning_output: FILE
650# Means the same as 'warning', except the regular expression
651# lines are contains in FILE.
652#
653# map: FILE
654# Adding this option will cause the linker to generate a linker
655# map file, using the -Map=MAPFILE command line option. If
656# there is no -Map=MAPFILE in the 'ld: FLAGS' then one will be
657# added to the linker command line. The contents of the
658# generated MAPFILE are then compared against the regexp lines
659# in FILE using `regexp_diff' (see below for details).
660#
661# section_subst: no
662# Means that the section substitution for objdump is disabled.
663#
664# Each option may occur at most once unless otherwise mentioned.
665#
666# After the option lines come regexp lines. run_dump_test calls
667# regexp_diff to compare the output of the dumping tool against the
668# regexps in FILE.d.
