-O: Specify Output File
By default the assembler determines the name of the object file to be created by strip-
ping any suffix or extension from the first source filename and appending .obj. The

-O
option allows the user to override the default filename and specify a new name for
the object file.

-T: Specify Listing Page Width
This option allows specification of the assembly list file page width, in characters.

should be a decimal number greater than 41. The default width is 80 characters.

-V: Produce Assembly Debug Information
This option will include line number and filename information in the object file produced
by the assembler. Such information may be used by debuggers.
by the assembler. Such information may be used by debuggers.
Note that the line numbers will correspond with assembler code lines in the assembler
file. This option should not be used when assembling an assembly file produced by the
code generator. In that case, debug information should relate back to the original C
source, not the intermediate assembly code.

6.3.12
-VER:Specify Version Information
This option allows the full version information, including optional text to indicate beta
builds or release candidate builds, to be passed to the assembler. This information is
only used in the title of the assembly list file and is not reflected in the output to the
--VER
builds or release candidate builds, to be passed to the assembler. This information is
only used in the title of the assembly list file and is not reflected in the output to the
--VER
option.
6.3.13
-X: Strip Local Symbols
The object file created by the assembler contains symbol information, including local
symbols; i.e., symbols that are neither public or external. The -X option will prevent the
local symbols from being included in the object file, thereby reducing the file size.

--CHIP: Specify Device Name
This option defines the device which is being used. The device type can also be indi-
cated by use of the device directive in the assembler source file, see
Section 6.4.9.20 “PROCESSOR”. You can also add your own processors to the
compiler via the compiler’s chipinfo file.

This option is applied if compiling using xc8, the command-line driver and the --CHIP

--DISL: Disable Messages
This option is mainly used by the command-line driver, xc8, to disable particular
message numbers. It takes a comma-separate list of message numbers that will be
disabled during compilation.
