Arm Compiler armasm User Guide : --brief_diagnostics, --no_brief_diagnostics

--brief_diagnostics, --no_brief_diagnostics

Enables and disables the output of brief diagnostic messages.

This option instructs the assembler whether to use a shorter form of the diagnostic output. In this form, the original source line is not displayed and the error message text is not wrapped when it is too long to fit on a single line. The default is --no_brief_diagnostics.
