-x
Specifies the language of source files.
Syntax
-x language
Where:
language-
Specifies the language of subsequent source files, one of the following:
c- C code.
c++- C++ code.
assembler-with-cpp- Assembly code containing C directives that require the C preprocessor.
assembler- Assembly code that does not require the C preprocessor.
Usage
-x overrides the default language
standard for the subsequent input files that follow it on the command-line. For
example:
armclang
inputfile1.s -xc inputfile2.s inputfile3.s
In this example, armclang treats the input files as follows:
inputfile1.sappears before the-xcoption, so armclang treats it as assembly code because of the.ssuffix.inputfile2.sandinputfile3.sappear after the-xcoption, so armclang treats them as C code.
Note
Use-std to set the default
language standard.Default
By default the compiler determines the source file language from the filename suffix, as follows:
.cpp,.cxx,.c++,.cc, and.CCindicate C++, equivalent to-x c++..cindicates C, equivalent to-x c..s(lower-case) indicates assembly code that does not require preprocessing, equivalent to-x assembler..S(upper-case) indicates assembly code that requires preprocessing, equivalent to-x assembler-with-cpp.
