REMARKS
•
Pragma REFALIGNED without a pointer-name-list specifies the default
alignment for the entire compilation and can be used in the command line or in the
source text.
•
A global REFALIGNED pragma affects only pointers that do not point to classes,
structs, or unions.
•
If you declare a TYPEDEF and it is of a type that has been given an explicit
reference alignment, then that REFALIGNED value is propagated to the new
TYPEDEF. Otherwise, the new TYPEDEF gets the current global default
REFALIGNED value.
•
When SHARED2 substructs are nested within AUTO, PLATFORM, or SHARED8
structs, the substruct contributes only a 1-byte or 2-byte alignment requirement to
the overall struct, even when the substruct contains 4-byte or 8-byte field types.
REMARKS
The REMARKS pragma directs the native C and C++ compilers to issue remarks.
The pragma default settings are:
Usage Guidelines
•
The REMARKS pragma can be entered only on the compiler RUN command line.
For OSS, the pragma can be specified with the -Wremarks flag of the c89 utility.
•
Remarks are informative diagnostics that are less severe than warnings.
