<strong>Compiler</strong> Diagnostic Messages<br />
6.4 Prefix letters in compiler diagnostic messages<br />
The compilation tools automatically insert an identification letter to diagnostic messages. See<br />
Table 6-2. <strong>Using</strong> <strong>the</strong>se prefix letters enables <strong>the</strong> tools to use overlapping message ranges.<br />

The following rules apply:<br />
• All of <strong>the</strong> compilation tools act on a message number without a prefix.<br />
• A message number with a prefix is only acted on by <strong>the</strong> tool with <strong>the</strong> matching prefix.<br />
• A tool does not act on a message with a non-matching prefix.<br />
There<strong>for</strong>e, <strong>the</strong> compiler prefix C can be used with --diag_error, --diag_remark, and<br />
--diag_warning, or when suppressing messages, <strong>for</strong> example:<br />
armcc --diag_suppress=C1287,C3017 ...<br />
Use <strong>the</strong> prefix letters to control options that are passed from <strong>the</strong> compiler to o<strong>the</strong>r tools, <strong>for</strong><br />
example, include <strong>the</strong> prefix letter L to specify linker message numbers.<br />
