/* Specs are strings containing lines, each of which (if not blank)
is made up of a program name, and arguments separated by spaces.
%b substitute the basename of the input file being processed.
This is the substring up to (and not including) the last period
and not including the directory.
- %g substitute the temporary-file-name-base. This is a string chosen
- once per compilation. Different temporary file names are made by
- concatenation of constant strings on the end, as in `%g.s'.
- %g also has the same effect of %d.
- %u like %g, but make the temporary file name unique.
- %U returns the last file name generated with %u.
+ %gSUFFIX
+ substitute a file name that has suffix SUFFIX and is chosen
+ once per compilation, and mark the argument a la %d. To reduce
+ exposure to denial-of-service attacks, the file name is now
+ chosen in a way that is hard to predict even when previously
+ chosen file names are known. For example, `%g.s ... %g.o ... %g.s'
+ might turn into `ccUVUUAU.s ccXYAXZ12.o ccUVUUAU.s'. SUFFIX matches
+ the regexp "[.A-Za-z]*" or the special string "%O", which is
+ treated exactly as if %O had been pre-processed. Previously, %g
+ was simply substituted with a file name chosen once per compilation,
+ without regard to any appended suffix (which was therefore treated
+ just like ordinary text), making such attacks more likely to succeed.
+ %uSUFFIX
+ like %g, but generates a new temporary file name even if %uSUFFIX
+ was already seen.
+ %USUFFIX
+ substitutes the last file name generated with %uSUFFIX, generating a
+ new one if there is no such last file name. In the absence of any
+ %uSUFFIX, this is just like %gSUFFIX, except they don't share
+ the same suffix "space", so `%g.s ... %U.s ... %g.s ... %U.s'
+ would involve the generation of two distinct file names, one
+ for each `%g.s' and another for each `%U.s'. Previously, %U was
+ simply substituted with a file name chosen for the previous %u,
+ without regard to any appended suffix.
%d marks the argument containing or following the %d as a
temporary file name, so that that file will be deleted if CC exits
successfully. Unlike %g, this contributes no text to the argument.
Input files whose names have no recognized suffix are not compiled
at all, but they are included among the output files, so they will
be linked.
- %O substitutes the suffix for object files.
+ %O substitutes the suffix for object files. Note that this is
+ handled specially when it immediately follows %g, %u, or %U,
+ because of the need for those to form complete file names. The
+ handling is such that %O is treated exactly as if it had already
+ been substituted, except that %g, %u, and %U do not currently
+ support additional SUFFIX characters following %O as they would
+ following, for example, `.o'.
%p substitutes the standard macro predefinitions for the
current target machine. Use this when running cpp.
%P like %p, but puts `__' before and after the name of each macro.
This allows config.h to specify part of the spec for running as.
%A process ASM_FINAL_SPEC as a spec. A capital A is actually
used here. This can be used to run a post-processor after the
- assembler has done it's job.
+ assembler has done its job.
%D Dump out a -L option for each directory in startfile_prefixes.
If multilib_dir is set, extra entries are generated with it affixed.
%l process LINK_SPEC as a spec.
arguments. CC considers `-o foo' as being one switch whose
name starts with `o'. %{o*} would substitute this text,
including the space; thus, two arguments would be generated.
+ %{^S*} likewise, but don't put a blank between a switch and any args.
%{S*:X} substitutes X if one or more switches whose names start with -S are
specified to CC. Note that the tail part of the -S option
(i.e. the part matched by the `*') will be substituted for each
%{|!S:X} like %{!S:X}, but if there is an S switch, substitute `-'.
%{.S:X} substitutes X, but only if processing a file with suffix S.
%{!.S:X} substitutes X, but only if NOT processing a file with suffix S.
+ %{S|P:X} substitutes X if either -S or -P was given to CC. This may be
+ combined with ! and . as above binding stronger than the OR.
%(Spec) processes a specification defined in a specs file as *Spec:
%[Spec] as above, but put __ around -D arguments
value is ignored, except with {S*} where S is just one letter; this
passes all matching options.
-The character | is used to indicate that a command should be piped to
-the following command, but only if -pipe is specified.
+The character | at the beginning of the predicate text is used to indicate
+that a command should be piped to the following command, but only if -pipe
