ARM Compiler toolchain v4.1 for µVision Using the Compiler

Compiler Features
4.27 Manually specifying the filename and location of a PreCompiled Header (PCH)
file
To manually specify the filename and location of a PCH file, use any of the following compiler
command-line options:
• --create_pch=filename
• --pch_dir=directory
• --use_pch=filename
If you use --create_pch or --use_pch with the --pch_dir option, the indicated filename is
appended to the directory name, unless the filename is an absolute path name.
Note
If multiple options are specified on the same command line, the following rules apply:
• --use_pch takes precedence over --pch
• --create_pch takes precedence over all other PCH file options.
