12 The information in this man page is an extract from the full documenta‐
13 tion of gputils and is limited to the meaning of the options. For com‐
14 plete and current documentation, refer to "gputils.ps" located in the
15 gputils docs directory.

18 gpasm is an assembler for Microchip (TM) PIC (TM) micro-controllers.
19 It's intended to be compatible with the manufacturer's MPASM assembler.
20 gpasm is part of gputils. Check the gputils(1) manpage for details on
21 other GNU PIC utilities.

24 Below is a summary of the gpasm options. gpasm options always super‐
25 sede any settings in the source code.
26 -a FMT, --hex-format FMT
28 GPASM supports inhx8m, inhx8s, inhx16, and inhx32 hex file for‐
29 mats. This option controls which hex file format is used. The
30 default is inhx32.
31 -c, --object
33 Output a relocatable object (new COFF format).
34 -C, --old-coff
36 Output a relocatable object (old COFF format).
37 -d, --debug
39 Output debug messages.
40 -D SYM=VAL, --define SYM=VAL
42 Define SYM with value VAL. This is equivalent to placing
43 "#define SYM VAL" in the source.
44 -e [ON|OFF], --expand [ON|OFF]
46 Macro expansion in the listing file is controlled using the
47 EXPAND and NOEXPAND directives. This option can force either
48 directive to be ignored. When "ON" is selected the macros are
49 always expanded regardless of the presence of NOEXPAND. Like‐
50 wise, "OFF" will force macros not to be expanded.
51 -f, --full-address
53 Show full address in .lst file at the memory map region.
54 -g, --debug-info
56 Use debug directives for COFF.
57 -h, --help
59 Show the usage message and exit.
60 -i, --ignore-case
62 All user defined symbols and macros are case sensitive. This
63 option makes them case insensitive.
64 -I DIR, --include DIR
66 The top level assembly file is passed to gpasm as an argument.
67 This file can contain INCLUDE directives. These directives open
68 the specified file and then its contents are assembled. GPASM
69 searches for these files in the local directory. If the file is
70 not located, the default header path is checked. Finally, all
71 paths specified using this argument are searched.
72 -j, --sdcc-dev16-list
74 Help to the extension of the pic16devices.txt file in the sdcc
75 project. Using by itself, displays the all '16e' devices. Along
76 with the '-p' option, shows only the specified device.
77 -k, --error
79 Enables creation of the error file.
80 -l[12[ce]|14[cef]|16[ce]], --list-chips[=([12[ce]|14[cef]|16[ce]])]
82 List supported processors based on various aspects. (f => x)
83 -L, --force-list
85 Ignore NOLIST directives. This forces gpasm to print every line
86 assembled in the list file output.
87 -m, --dump
89 Upon completion of the final pass of assembly, display the con‐
90 tents of instruction memory.
91 --mpasm-compatible
93 This option sets the MPASM compatibility mode.
94 -M, --deps
96 Output a dependency file.
97 -n, --dos
99 By default, gpasm generates hex files using ISO format. How‐
100 ever, some device programmers required a DOS formatted file.
101 This option will cause gpasm to generate a DOS formatted hex
102 file.
103 -o FILE, --output FILE
105 Alternate name of output files. Option effect of:
106 -- If the "-c" option included in the command line:
107 FILE.o, FILE.lst, FILE.err
108 (The "FILE.o" should specified.)
109 -- If the "-c" option not included in the command line:
110 FILE.hex, FILE.cod, FILE.lst, FILE.err
111 (The "FILE.hex" should specified.)
112 -p PROC, --processor PROC
114 Select the processor.
115 -P FILE, --preprocess FILE
117 Write preprocessed asm file to FILE.
118 -q, --quiet
120 Suppress anything sent to standard output.
121 -r RADIX, --radix RADIX
123 The supported radices are BIN, DEC, OCT, and HEX. The default is
124 HEX.
125 -s[12[ce]|14[cef]|16[ce]],
127 --list-processor-properties[=([12[ce]|14[cef]|16[ce]])]
128 Lists properties of the processors. Using by itself, displays
130 the all devices or group of the devices. Along with the '-p'
131 option, shows only the specified device. (f => x)
132 -S [0|1|2], --strict [0|1|2]
134 Set the strict level of the recommended instruction-parameters
135 (W or F and A or B). The "strict messages" have higher priority
136 than the warnings. (See: -w [0|1|2]) [0]
137 0: Is the default. No strict messages.
138 1: Show warning messages if one of is missing.
139 2: Show error messages if one of is missing.
140 -t, --sdcc-dev14-list
142 Help to the extension of the pic14devices.txt file in the sdcc
143 project. Using by itself, displays the all '14' and '14e'
144 devices. Along with the '-p' option, shows only the specified
145 device.
146 --strict-options
148 If this is set, then an option may not be parameter of an
149 another option. For example: -I -c
150 -u, --absolute
152 Use absolute paths.
153 -v, --version
155 Show the version information and exit.
156 -w [0|1|2], --warning [0|1|2]
158 This option sets the message level.
159 0: Is the default. It will allow all messages, warnings and
160 errors to be reported.
161 1: Will suppress the messages.
162 2: Will suppress the messages and warnings.
163 -X, --macro-dereference
165 Use the source from where the macro was invoked for errors.
166 -y, --extended
168 Enable 18xx extended mode.
