| |
| ; This file is processed by the script opts.sh. It is a database of |
| ; command line options, with each record separated by a blank line, |
| ; and each field appearing on its own line. The first field is the |
| ; command-line switch with the leading "-" removed. All options |
| ; beginning with "f" or "W" are implicitly assumed to take a "no-" |
| ; form; this form should not be listed. If you do not want this |
| ; negative form and you want it to be automatically rejected, add |
| ; RejectNegative to the second field. |
| |
| ; The second field is a space-separated list of which parts of the |
| ; compiler recognize the switch, as declared by "Language" entries. |
| ; If the switch takes an argument, then you should also specify |
| ; "Joined" and/or "Separate" to indicate where the argument can |
| ; appear. If a Joined argument can legitimately be omitted, specify |
| ; "JoinedOrMissing" instead of "Joined". If the argument to a switch |
| ; is a non-negative integer, you can specify "UInteger" and the switch |
| ; decoder will convert the argument for you, or complain to the user |
| ; if the argument is invalid. "Var(name,set)" creates an integer |
| ; variable "name". The variable is declared and initialized to value |
| ; given by "Init(value)" (or zero if this property is not defined). |
| ; When the option is passed to compiler, this variable is set to "set" |
| ; if value passed through the flag is nonzero, !"set" if value is zero, |
| ; or to value if "set" is omitted. If "VarExists" is specified, the |
| ; declaration for the variable is not created. If "Report" is specified, |
| ; the flag is output with -fverbose-asm. |
| |
| ; The third field is the help text to output with --help. This is |
| ; automatically line-wrapped on output. Normally the switch is output |
| ; automatically, with the help text on the right hand side of the |
| ; output. However, if the help text contains a tab character, the |
| ; text to the left of the tab is output instead of the switch, and the |
| ; text to its right forms the help. This is useful for elaborating on |
| ; what type of argument a switch takes, for example. If the second |
| ; field contains "Undocumented" then nothing is output with --help. |
| ; Only do this with good reason like the switch being internal between |
| ; the driver and the front end - it is not an excuse to leave a switch |
| ; undocumented. |
| |
| ; Comments can appear on their own line anwhere in the file, preceded |
| ; by a semicolon. Whitespace is permitted before the semicolon. |
| |
| ; For each switch XXX below, an enumeration constant is created by the |
| ; script opts.sh spelt OPT_XXX, but with all non-alphanumeric |
| ; characters replaced with an underscore. |
| |
| ; Please try to keep this file in ASCII collating order. |
