Compiler options

191

--no_ubrof_messages --no_ubrof_messages

Use this option to minimize the size of your application object file by excluding

messages from the UBROF files. A file size decrease of up to 60% can be expected. Note

that the XLINK diagnostic messages will, however, be less useful when you use this

option.

This option is related to the Output options in the C/C++ Compiler category in IAR

Embedded Workbench.

--no_tbaa --no_tbaa

Use --no_tbaa to disable type-based alias analysis. When this options is not used, the

compiler is free to assume that objects are only accessed through the declared type or

through

unsigned char. See Type-based alias analysis, page 124 for more

information.

This option is related to the Optimization options in the C/C++ Compiler category in

IAR Embedded Workbench.

--no_typedefs_in_diagnostics --no_typedefs_in_diagnostics

Normally, when a type is mentioned in a message from the compiler, most commonly

in a diagnostic message of some kind, the typedef names that were used in the original

declaration are used whenever they make the resulting text shorter. For example,

typedef int (*MyPtr)(char const *);

MyPtr p = "foo";

will give an error message like the following:

Error[Pe144]: a value of type "char *" cannot be used to

initialize an entity of type "MyPtr"

If the --no_typedefs_in_diagnostics option is specified, the error message will

be like this:

Error[Pe144]: a value of type "char *" cannot be used to

initialize an entity of type "int (*)(char const *)"

--no_warnings

By default, the compiler issues warning messages. Use this option to disable all warning

messages.

To set the equivalent option in IAR Embedded Workbench, select
