4.33 Message output during Precompiled Header (PCH) processing

Whenever the compiler creates or uses a PCH file, it displays a message. You can suppress these messages or make them more verbose.

Note:

Support for Precompiled Header (PCH) files is deprecated from ARM Compiler 5.05 onwards on all platforms. Note that ARM Compiler on Windows 8 never supported PCH files.

When the compiler creates or uses a PCH file, it displays the following kind of message:

test.c: creating precompiled header file test.pch

You can suppress this message with the compiler command-line option --no_pch_messages.

The --pch_verbose option enables verbose mode. In verbose mode, the compiler displays a message for each PCH file that it considers but does not use, giving the reason why it cannot be used.
