Target and Compiler

Specify target environment

To match your run-time environment, use the target and compiler options. The analysis uses these options to determine variable sizes, language extensions and compiler-specific behavior. If you still get compilation errors, you can work around specific errors with options from the Macros and Environment Settings category.

Polyspace Options

expand all

Language

`Source code language (-lang)`	Specify language of source files
`C standard version (-c-version)`	Specify C language standard followed in source code
`C++ standard version (-cpp-version)`	Specify C++ language standard followed in source code

Compiler

Required

`Compiler (-compiler)`	Specify the compiler that you use to build your source code
`Target processor type (-target)`	Specify size of data types and endianness by selecting a predefined target processor
`Generic target options`	Specify size of data types and endianness by creating your own target processor

Optional

`Management of size_t (-size-t-type-is)`	Specify the underlying data type of `size_t`
`Management of wchar_t (-wchar-t-type-is)`	Specify the underlying data type of `wchar_t`
`Block char16/32_t types (-no-uliterals)`	Disable Polyspace definitions for `char16_t` or `char32_t`
`Sfr type support (-sfr-types)`	Specify sizes of `sfr` types for code developed with Keil or IAR compilers
`Pack alignment value (-pack-alignment-value)`	Specify default structure packing alignment for code developed in Visual C++
`Ignore pragma pack directives (-ignore-pragma-pack)`	Ignore `#pragma pack` directives

Advanced

`Division round down (-div-round-down)`	Round down quotients from division or modulus of negative numbers instead of rounding up
`Enum type definition (-enum-type-definition)`	Specify how to represent an `enum` with a base type
`Signed right shift (-logical-signed-right-shift)`	Specify how to treat the sign bit for logical right shifts on signed variables
