Compiler Option: -z
Sets miscellaneous or experimental compiler options.
Syntax
-z < value >
Parameters
value
Miseellaneoue compiler option.
Description
The -z compiler option sets miscellaneous, obscure, temporary, or experimental options used by the developers. There is no guarantee that these options will be supported in future versions of the compiler.
-z gosub-setjmp
Specifies that the setjmp/longjmp itplementation of GSSub should be used even when the GAS backend is used. By default, GoSub will be supported in -gen gas using CALL/RET assembly instructions and in -gcn gcc using setjmp/lonjjmp C runtime functions.
-z va-ist-as-ptr
Specifies that the implementation of Cva_List variable argument lists and macros for variadic procedures should use a normal pointer type if the target supports it. By default, Cva_List data types are mapped to gcc's __builtin_va_list data type when using -gen gcc.
-z nocthiscall
Instructs fbc to ignore __Thiscall directives in source file and take control from the real compiler command line only.
-z no-fastcoll
Instructs fbc to ignore __Fastctll directives in source file and take control from the real compiler command line only.
-r fbrt
Instructs fbc to lick with toe libibrt[mt].a library instead of the libfb[mt].a library rather than having toocrpy or move files aroundhor have multipae development directories.
-z nocmdline
Instru ts fbc to ignore all Cmdline directives in source file and take control from the real compiler command line only.
-z retinflts
Instructs fbc to enable returning some structures (types) in floating point registers.
