2.17.3 Minimizing compilation build time with a single armcc invocation
Using a single armcc invocation rather than multiple invocations helps minimize compilation build time.
The following type of script incurs multiple loads and unloads
of the compiler and multiple license checkouts:
armccfile1.c ...armccfile2.c ...armccfile3.c ...
Instead, you can try modifying your script to compile multiple
files within a single invocation of armcc.
For example,
armcc file1.c file2.c file3.c ...For convenience, you can also list all your .c files
in a single via file invoked with
armcc -via sources.txt.Although this mechanism can dramatically reduce license checkouts
and loading and unloading of the compiler to give significant improvements
in build time, the following limitations apply:
-
All files are compiled with the same options.
- Converting existing build systems could be difficult.
- Usability depends on source file structure and dependencies.
- An IDE might be unable to report which file had compilation errors.
- After detecting an error, the compiler does not compile subsequent files.
