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.
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.
