Filename suffixes recognized by the compiler

The compiler uses filename suffixes to identify the classes of file involved in compilation and in the link stage. The filename suffixes recognized by the compiler are described in Table 1.

Note

Explicitly specifying --c90, --c99, or --cpp overrides the effect of filename suffixes.

Table 1. Filename suffixes recognized by the compiler

Suffix	Description	Usage notes
`.c`	C source file	Implies `--c90`
`.C`	C or C++ source file	On UNIX platforms, implies `--cpp`. On non-UNIX platforms, implies `--c90`.
`.cpp` `.c++` `.cxx` `.cc` `.CC`	C++ source file	Implies `--cpp` The compiler uses the suffixes `.cc` and `.CC` to identify files for implicit inclusion.
`.d`	Dependency list file	`.d` is the default output filename suffix for files output using the `--md` option.
`.h`	C or C++ header file	-
`.i`	C or C++ source file	A C or C++ file that has already been preprocessed, and is to be compiled without further preprocessing.
`.ii`	C++ source file	A C++ file that has already been preprocessed, and is to be compiled without further preprocessing.
`.lst`	Error and warning list file	`.lst` is the default output filename suffix for files output using the `--list` option.
`.a` `.lib` `.o` `.obj` `.so`	ARM, Thumb, or mixed ARM and Thumb object file or library.	-
`.pch`	Precompiled header file	`.pch` is the default output filename suffix for files output using the `--pch` option.
`.s`	ARM, Thumb, or mixed ARM and Thumb assembly language source file.	For files in the input file list suffixed with `.s`, the compiler invokes the assembler, armasm, to assemble the file. `.s` is the default output filename suffix for files output using either the option `-S` or `--asm`.
`.S`	ARM, Thumb, or mixed ARM and Thumb assembly language source file.	On UNIX platforms, for files in the input file list suffixed with `.S`, the compiler preprocesses the assembly source prior to passing that source to the assembler. On non-UNIX platforms, `.S` is equivalent to `.s`. That is, preprocessing is not performed.
`.sx`	ARM, Thumb, or mixed ARM and Thumb assembly language source file.	For files in the input file list suffixed with `.sx`, the compiler preprocesses the assembly source prior to passing that source to the assembler.
`.txt`	Text file	`.txt` is the default output filename suffix for files output using the `-S` or `--asm` option in combination with the `--interleave` option.
