Signed-Bitfield; Signed-Char; Syntax-Only; Sysdefs - Analog Devices VISUALDSP++ 3.5 Manual

A compiler will "pass along" the appropriate
when invoking another VisualDSP++ tool, for example, when the com-
piler driver invokes assembler and linker.

-signed-bitfield

The
-signed-bitfield
compiler to make bitfields which have not been declared with an explicit
signed or unsigned keyword to be signed. This switch does not effect plain
one-bit bitfields which are always unsigned. This is the default mode. See
also the
-unsigned-bitfield

-signed-char

The
-signed-char
the default type for
__SIGNED_CHARS__
-unsigned-char

-syntax-only

The
-syntax-only
check the source code for syntax errors and warnings. No output files will
be generated with this switch.

-sysdefs

The
-sysdefs
several preprocessor macros describing the current user and user's system.
The macros are defined as character string constants and are used in func-
tions with null-terminated string arguments.
