Stack checking qualifiers
/noswstackcheck This option uses the non software-stack-checking ATPCS variant.
This is the default.
/swstackcheck This option uses the software-stack-checking ATPCS variant.
2.3.3 Setting the source language
This section describes options that determine the source language variant accepted by
the compiler (see also Controlling code generation on page 2-24).
The following options specify how strictly the compiler enforces the standards and
conventions of that language. By default, the C compilers compile ANSI-C, and the
C++ compilers compile as much as they can of ISO/IEC C++.
-ansi This option compiles ANSI standard C. This is the default for armcc and
tcc. The default mode is a fairly strict ANSI compiler, but without some
of the inconvenient features of the ANSI standard. There are also some
minor extensions allowed (for example
// in comments and $ in
identifiers).
-ansic This option compiles ANSI standard C. This option is synonymous with
the
-ansi option.
-cpp This option compiles ISO/IEC C++. This option is the default with the
C++ compilers and not available with the C compilers.
-embeddedcplusplus
This option compiles standard Embedded C++ (EC++). This option is
not available with the C compilers.
-strict This option enforces more stringent conformance to the ANSI C standard
and the ISO/IEC C++ standard. For example, the following code:
static struct T {int i; };
gives an error when compiled with -cpp -strict , but only a warning with
-cpp . Because no object is declared, static is spurious. In the C++
standard, the code shown is therefore illegal.
You can combine language options:
armcc -ansi Compiles ANSI standard C. This is the default.
armcc -strict Compiles strict ANSI standard C.
armcpp Compiles standard C++.
