ARM Compiler toolchain Using the Compiler: Getting Started with the Compiler

Getting Started with the Compiler

The following topics outline the command-line options accepted by the ARM compiler, armcc. They describe how to invoke the compiler, how to pass options to other tools provided with the compiler, and how to control diagnostic messages:

Compiler command-line syntax
Compiler command-line options listed by group
Default compiler behavior
Order of compiler command-line options
Using stdin to input source code to the compiler
Directing output to stdout
Filename suffixes recognized by the compiler
Compiler output files
Factors influencing how the compiler searches for header files
Compiler command-line options and search paths
Compiler search rules and the current place
The ARMCCnINC environment variable
Code compatibility between separately compiled and assembled modules
Linker feedback during compilation
Using GCC fallback when building applications
Unused function code
Minimizing code size by eliminating unused functions during compilation
Minimizing code size by reducing compilation required for interworking
Compilation build time
How to minimize compilation build time
Minimizing compilation build time with a single armcc invocation
Effect of --multifile on compilation build time
Minimizing compilation build time with parallel make
Compilation build time and operating system choice.
