[edk2] [PATCH] BaseTools: align ENCODE_ERROR macro with MdePkg version

Posted by Leif Lindholm 6 years, 4 months ago

BaseTools' BaseTypes.h defined the ENCODE_ERROR macro as
whereas MdePkg defines it as

When building with GCC 6.3 (at least) the former triggers
"error: overflow in implicit constant conversion [-Werror=overflow]"
Resolve this by aligning it with the latter one.

This also requires aligning the BaseTools typedef of RETURN_STATUS with
the MdePkg one: INTN -> UINTN.

Add an explicit initialization of *Alignment to 0 in GenFfs.c
GetAlignmentFromFile to get rid of a warning occuring with GCC after
this change (-Werror=maybe-uninitialized).
