Tells the compiler that the __regcall
calling convention should be used for functions that do not directly specify a
calling convention.
Syntax
Linux:
-regcall
Windows:
/Qregcall
Arguments
None
Default
- OFF
- The __regcall calling convention will only be used if a function explicitly specifies it.
Description
This option tells the compiler that the __regcall calling
convention should be used for functions that do not directly specify a calling
convention. This calling convention ensures that as many values as possible are
passed or returned in registers.
It ensures that __regcall is the default calling convention for functions in
the compilation, unless another calling convention is specified in a
declaration.
This calling convention is ignored if it is specified for a function with
variable arguments.
Note that all __regcall functions must have prototypes.
