TASKING VX-toolset for ARM User Guide}{/* the entire for loop is part of the pragma optimize */a += i;}v = a;Supported pragmasThe compiler recognizes the following pragmas, other pragmas are ignored. Pragmas marked with (*)support a label prefix.alias symbol=defined_symbolDefine symbol as an alias for defined_symbol. It corresponds to an equate directive (.EQU) at assemblylevel. The symbol should not be defined elsewhere, and defined_symbol should be defined with staticstorage duration (not extern or automatic).call {near | far | default | restore} (*)By default, functions are called with 26-bit PC-relative calls. This near call is directly coded into theinstruction, resulting in higher execution speed and smaller code size. The destination address of a nearcall must be located within +/-32 MB from the program counter.The other call mode is a 32-bit indirect call. With far calls you can address the full range of memory. Theaddress is first loaded into a register after which the call is executed.See C compiler option --call (-m).compactmaxmatch {value | default | restore} (*)With this pragma you can control the maximum size of a match.See C compiler option --compact-max-size.extension isuffix [on | off | default | restore] (*)Enables a language extension to specify imaginary floating-point constants. With this extension, you canuse an "i" suffix on a floating-point constant, to make the type _Imaginary.float 0.5iextern symbolNormally, when you use the C keyword extern, the compiler generates an .EXTERN directive in thegenerated assembly source. However, if the compiler does not find any references to the extern symbolin the C module, it optimizes the assembly source by leaving the .EXTERN directive out.With this pragma you can force an external reference (.EXTERN assembler directive), even when thesymbol is not used in the module.16
