M11(1) General Commands Manual M11(1)
m11 - Macro-11 assembler for UNIX
m11 [ option1 option2 ... ] file1 file2 ... filen
M11 assembles the concatenation of the specified files (file1, etc.) and terminates when an ``.end'' statement is encountered. The
resulting object file is usually named filen.obj (see below). If a file argument, filei does not contain a ``.'' in its name, the file
filei.m11 will be sought before filei itself.
Options, if desired, may appear anywhere in the command, and are chosen from the following list. All options are interpreted before any
files are read.
-ls Produce an assembly listing and place in filen.lst
-lt Produce an assembly listing on the standard output.
-fl If coupled with the -ls or -lt directives, makes the listing have a shortened format. It is shorthand for
-uc Simulate an initial .dsabl lc directive. Force all characters in macro definitions to be upper case. This flag makes lower-case
handling in m11 compatable with the DEC Macro-11 assemblers.
-um Force all characters in macro definitions to be upper case. This flag makes lower-case handling in this release of m11 compatable
with previous versions of m11.
-de Make all option choices needed to make assembly mimic DEC Macro-11. Implies (inter alia) the -uc flag. This includes the Johns
Hopkins asm assembler.
-ha Make all option choices needed to make assembly mimic earlier (Harvard) releases of m11. This implies the -um flag. Default .psect
and .csect attributes are set up in the funny Harvard way.
-mx Produce a listing of the source program as it appears after macro expansion. Macro calls, conditional directives and so on appear
in the listing as comments. Listing appears on standard output. No machine code is generated or listed. This option is meant to
correspond to the -E or -P options of the C compiler cc(1).
-my Like -mx, except that macro calls and conditional directives do not show up in the listing.
-10 Generate an error whenever op codes not in the PDP-11 ``standard instruction set'' are encountered. Programmers writing for a PDP
11/10 can catch instructions illegal for that machine by using this argument.
The default attributes for a .psect or unnamed .csect are redefined, using the colon-separated list args of valid .psect
The default attributes for an .asect are redefined.
-dp:c The default attributes for a named .csect are redefined.
Simulate an initial .list arglist directive. All .list and .nlist directives in the program text which attempt to change the set-
tings established with the -li flag will be ignored.
Like -li:arglist, but for the .nlist directive.
Similarly, for the .enabl directive.
Similarly, but for the .dsabl directive.
Produces a cross-reference listing. If the -ls option is also included, the cross-reference listing will follow the assembly list-
ing in filen.lst. References which are tagged with the symbol # are definitions. References tagged with * are destuctive refer-
ences: the value of the symbol or variable in question is changed. Arglist consists of colon-separated keywords from the following
set. The keywords may be prefix abbreviated:
sym All user-defined symbols are indexed.
mac All macro names are indexed.
per All uses of permanent symbols - op codes, directives, etc - are indexed.
pse All psect names are indexed. For compatability with the RT-11 CREF program, the argument cse is synonymous with pse.
err All errors are indexed.
reg All register uses are indexed.
If no arglist is specified the default sym:mac:err is used. In the listing page and line numbers for uses of symbols are followed
by a # sign if the symbol is defined and by a * sign if the symbol is modified.
-lp Same as -ls, but also spools filen.lst for printing upon completion.
-no No object file is produced. This is useful for syntax checking or list producing.
-xs:n Allots nK words of extra space for symbol table and macro storage. NOTE: This option is currently inoperative: m11 automatically
allots core for its tables as needed.
-xx Debug flag: generate all kinds of wierd hack flack.
-ns No symbol table is included in the object file (thus ddt knows of no symbols from this assembly).
-sx Make the symbol table contain ``local symbols'' as well as ordinary symbols.
-u Treat form feed characters as spaces. This will make m11's idea of line numbers coincide with the UNIX text editors. Macro-11
statements containing imbedded form feed characters will be parsed differently when the -u flag is in effect.
Override the convention of using last name as file name. Instead, use names file.obj and file.lst for object and listing files.
This implementation of Macro-11 is a distant hand-me down from an old DEC Macro-11 modified at Harvard University in the early 1970's. It
is grubby with smudges by Brent Byer, F. J. Howard, Bob Bowering, and Jim Reeds. It does not implement keyword arguments such as are
described in section 7.3.6 of the DEC manual. The .enabl abs option does not work. Listing control is by default .list ttm. Unlike ear-
lier editions of m11 at UCB and at Harvard, it does treat immediate constants of floating point operations correctly: see the last para-
graph of section 6.4.2 on the middle of page 6-27 of the DEC manual. M11 has several directives not described in the DEC manual. See the
New UCB M11 Manual. The default attributes for .psects are different from those described in the DEC manual, but may be changed by the -dp
flag. The .enabl glb feature is implemented: undefined symbols are taken as undefined global externals.
