DejaGnu directives, which know nothing about the GCC directives, so the
DejaGnu directives must precede GCC directives.
-Several test directives include selectors which are usually preceded by
-the keyword @code{target} or @code{xfail}. A selector is: one or more
-target triplets, possibly including wildcard characters; a single
-effective-target keyword; or a logical expression. Depending on the
-context, the selector specifies whether a test is skipped and reported
-as unsupported or is expected to fail. Use @samp{*-*-*} to match any
-target.

@node Selectors
@subsection Selecting targets to which a test applies
+<<<<<<< HEAD
+
+Several test directives include @var{selector}s to limit the targets
+for which a test is run or to declare that a test is expected to fail
+on particular targets.
+
+A selector is:
+@itemize @bullet
+@item one or more target triplets, possibly including wildcard characters
+@item a single effective-target keyword (@pxref{Effective-Target Keywords})
+@item a logical expression
+@end itemize
+
+Depending on the
+context, the selector specifies whether a test is skipped and reported
+as unsupported or is expected to fail. Use @samp{*-*-*} to match any
+target.
+
+A selector expression appears within curly braces and uses a single
+logical operator: one of @samp{!}, @samp{&&}, or @samp{||}. An
+operand is another selector expression, an effective-target keyword,
+a single target triplet, or a list of target triplets within quotes or
+curly braces. For example:
+
+@smallexample
+@{ target @{ ! "hppa*-*-* ia64*-*-*" @} @}

+@{ xfail @{ lp64 || vect_no_align @} @}
+@end smallexample
+
+@node Effective-Target Keywords
+@subsection Keywords describing target attributes
+
+Effective-target keywords identify sets of targets that support
+particular functionality. They are used to limit tests to be run only
+for particular targets, or to specify that particular sets of targets
+are expected to fail some tests.
+
+Effective-target keywords are defined in @file{lib/target-supports.exp} in
+the GCC testsuite, with the exception of those that are documented as
+being local to a particular test directory.
+
+The @samp{effective target} takes into account all of the compiler options
+with which the test will be compiled, including the multilib options.
+By convention, keywords ending in @code{_nocache} can also include options
+specified for the particular test in an earlier @code{dg-options} or
+@code{dg-add-options} directive.

+@subsection Features for @code{dg-add-options}
+
+The supported values of @var{feature} for directive @code{dg-add-options}
+are:
+
+@table @code
+@item bind_pic_locally
+Add the target-specific flags needed to enable functions to bind
+locally when using pic/PIC passes in the testsuite.
+
+@item c99_runtime
+Add the target-specific flags needed to access the C99 runtime.
+
+@item ieee
+Add the target-specific flags needed to enable full IEEE
+compliance mode.
+
+@item mips16_attribute
+@code{mips16} function attributes.
+Only MIPS targets support this feature, and only then in certain modes.
+@end table
+
+@node Require Support
+@subsection Variants of @code{dg-require-@var{support}}
+
+A few of the @code{dg-require} directives take arguments.
+
+@table @code
+@item dg-require-iconv @var{codeset}
+Skip the test if the target does not support iconv. @var{codeset} is
+the codeset to convert to.
+
+@item dg-require-profiling @var{profopt}
+Skip the test if the target does not support profiling with option
+@var{profopt}.
+
+@item dg-require-visibility @var{vis}
+Skip the test if the target does not support the @code{visibility} attribute.
+If @var{vis} is @code{""}, support for @code{visibility("hidden")} is
+checked, for @code{visibility("@var{vis}")} otherwise.
+@end table
+
+The original @code{dg-require} directives were defined before there
+was support for effective-target keywords. The directives that do not
+take arguments could be replaced with effective-target keywords.
+
+@table @code
+@item dg-require-alias ""
+Skip the test if the target does not support the @samp{alias} attribute.
+
+@item dg-require-compat-dfp ""
+Skip this test unless both compilers in a @file{compat} testsuite
+support decimal floating point.
+
+@item dg-require-cxa-atexit ""
+Skip the test if the target does not support @code{__cxa_atexit}.
+This is equivalent to @code{dg-require-effective-target cxa_atexit}.
+
+@item dg-require-dll ""
+Skip the test if the target does not support DLL attributes.
+
+@item dg-require-fork ""
+Skip the test if the target does not support @code{fork}.
+
+@item dg-require-gc-sections ""
+Skip the test if the target's linker does not support the
+@code{--gc-sections} flags.
+This is equivalent to @code{dg-require-effective-target gc-sections}.
+
+@item dg-require-host-local ""
+Skip the test if the host is remote, rather than the same as the build
+system. Some tests are incompatible with DejaGnu's handling of remote
+hosts, which involves copying the source file to the host and compiling
+it with a relative path and "@code{-o a.out}".
+
+@item dg-require-mkfifo ""
+Skip the test if the target does not support @code{mkfifo}.
+
+@item dg-require-named-sections ""
+Skip the test is the target does not support named sections.
+This is equivalent to @code{dg-require-effective-target named_sections}.
+
+@item dg-require-weak ""
+Skip the test if the target does not support weak symbols.
+
+@item dg-require-weak-override ""
+Skip the test if the target does not support overriding weak symbols.
