ARM Compiler toolchain v4.1 for µVision Using the Compiler

Compiler Diagnostic Messages
6.5 Compiler exit status codes and termination messages
If the compiler detects any warnings or errors during compilation, the compiler writes the
messages to stderr. At the end of the messages, a summary message is displayed that gives the
total number of each type of message of the form:
filename: n warnings, n errors
where n indicates the number of warnings or errors detected.
Note
Remarks are not displayed by default. To display remarks, use the --remarks compiler option.
No summary message is displayed if only remark messages are generated.
The signals SIGINT (caused by a user interrupt, like ^C) and SIGTERM (caused by a UNIX
kill command) are trapped by the compiler and cause abnormal termination.
On completion, the compiler returns a value greater than zero if an error is detected. If no error
is detected, a value of zero is returned.
