SUBTTL SAIL/GOGOL MACROS AND SWITCHES
COMMENT ⊗ SWITCHES : AN INTRODUCTION
Conditional assembly runs rampant in SAIL. Most of the switches are used to
select options (debug or no debug, etc.) Some are only valid at Stanford.
There is one, EXPORT, tested by the macros NOEXPO and EXPO, which decides
whether this is for Stanford or somebody else.
We have a program which, by reading the SAIL files and looking for switch-
testing macros, can do the conditional assembly once and for all (removing
the conditional stuff from the files. It is such a set of files which
we normally send out, so if you see some switches and macros below that
never get referenced, it's because that code was taken out of your files.
The conditional assembly switches are assigned in the following files:
DCS DCS ←2 ;SLS (experimental) system
FTDEBUG ←1 ;include debugging in cmplr
;NOCOM COM2SW ←0 ;OBSOLETE SWITCH, WAS TO
; DISTINGUISH 2-SEG COMPILER
WOM DCS ←1 ;WOM (experimental) system
HEAD EXPORT ←if NDEF then 0 else EXPORT
DCS ←if NDEF then 0 else DCS
; COM2SW ←if NDEF then 1 else 0
SIXSW ←if NDEF then (if EXPO then 0 else 1) else SIXSW ;sixbit PPN's
HEDSYM ←if NDEF then 0 else HEDSYM ;With HEDSYM on, assembling HEAD
; yields HEAD.REL, a symbol
; file for the USERCON function
GLB GLOBSW ←1 ;runtimes know about glb mdl
LOW SEGS ←1 ;upper or lower assembly
LOWER ←1 ;assembles SAILOW or GLBLOW
UPPER ←0
UP SEGS ←1
LOWER ←0
UPPER ←1 ;assembles UPPER or GLOBAL
FILSPC IS PART OF HEAD AS OF NOV 1973
FILSPC FILXXX ←SAISGn ;SAIL upper segment name
SLOFIL ←SAILOW ;SAIL lower segment name
GLOB <
FILXXX ←GLBSGn ;global model upper segment name
SLOFIL ←GLBLOW ;global model lower segment name
>;GLOB
SGDEVC ←SYS ;device for segment files
SGPPNN ←0 ;PPN for segment files
LOCSYM ←0 ;no local uppers in lower file
NOPROT ←0 ;want upper segment protected
DB FTDEBUG ←1
SAIL LEAPSW ←1 ;LEAP exists
FTDEBUG ←if NDEF then 0 else FTDEBUG
GLOBC ←if LEAP and NOEXPO then 1 else if NDEF then 0 else GLOBC
PATSW ←if NDEF then 0 else PATSW ;compile AOS/SOS to PAT words
RENSW ←if NDEF then 1 else RENSW ;compile Re-entrant Code
TMPCSW ←if NDEF then (if EXPO then 1 else 0) else TMPCSW
;TMPCOR UUO available and used
;; #KS BY JRL (12-13-72) ADD LOADVR SWITCH
LOADVR ←if NDEF then 54 else LOADVR (for differences in block code
for required rel files,libraries in LOADER 54)
SAILRUN was a switch controlling some runtimes. Now runtimes will
be assembled to assume a compiler (since that's common anyway).
;; %BC% BY KVL (1/3/74) ADD BAIL SWITCH
BAISW ←if STANFO then 1 else 0 ;Bail only at stanford
GOGOL UPPER ←if NDEF then 0 else
UPPER ←if NDEF then 0 else UPPER
LOWER ←if NDEF then 0 else LOWER
SEGS ←UPPER or LOWER
GLOBSW ←if NDEF then 0 else GLOBSW
RENSW ←if NDEF then 1 else RENSW ;assemble Upper-Segment Library
SAILRUN no longer exists.
; SWITCH SETTINGS & MACROS
These macros come in pairs, and exist so that the above-mentioned
program will have an easy job of it. The meaning of each pair is
obvious. They may be used only as in the following example:
SW < ;or NOSW, starting in col. 1 (any comment out here)
(code to appear under this switch)
>;SW or NOSW, must be same, any comment out here
These things may be nested without confusing anyone.
Here are the macros

SAILOY.REL[1,3] is the low segment (always for NSAIL)
SAISG4.SEG[1,3] is the segment
LIBSA1, HLBSA1[1,3] are the libraries.
Will go back to SAISG3 shortly.

OLD SAIL (VERSION "15") BECOMES STANDARD PROCESSOR "OSAIL"
EXTENSION .OSA , LOW SEGMENT IS SAILOX (PREV SAILOW)
SAISG2.REL IS ITS UPPER
NOW SAISG3.SEG IS THE UPPER, SAILOW.REL IS THE LOWER, LIBSA1, HLBSA1
ARE THE LIBRARIES.

FEATURES
1. bug fixes
2. macro changes
3. process changes
SAISG6.SEG is the segment. LIBSA6.REL, the library.
GLBSG6.SEG is the global segment.

DSCR HERE
CAL MACRO
PAR ROUTINE NAME
DES For runtime routine vector. If this is a library or one-segment
run, this is equivalent to placing a label "HERE". Otherwise, the
label is placed on a JRST instruction in a vector of JRST's in the
upper segment. The JRST is to "HERE". This allows the code for
runtimes to be changed without forcing everyone to forsake their
SAIL-compiled core images.

RES For ZERODATA, the ZVBLS PC is switched to for the data. For others,
the VBLS PC. A check is made to ensure that the appropriate area is
big enough for the new data.
DES This allows data to be concentrated in one area (for reentrancy
consideration, one-instruction CLEAR operations, etc.), but to
be defined locally. Some special purpose programs can examine the
CREF listing file to print summaries, sorted cross-references, etc.

SUBTTL SAIL/GOGOL USER TABLE DESCRIPTION
DSCR USER DATA AREA TEMPLATE
DES These values serve as indices for the run-time routines
into the user's data table. The table is necessary to allow
the routines to be re-entrant. The table is allocated
in the SAILOR sequence at startup time; many of its values
(data area bounds, etc.) are placed in it at that time.
One can force re-initialization of this and all other dynamic
areas by setting GOGTAB to 0 before next CORGET.
