2.1.93 --interface_enums_are_32_bit
This option helps to provide compatibility between external code interfaces, with regard
to the size of enumerated types.
Usage
It is not possible to link an object file compiled with --enum_is_int, with another object
file that is compiled without --enum_is_int. The linker is unable to determine whether
or not the enumerated types are used in a way that affects the external interfaces, so on
detecting these build differences, it produces a warning or an error. You can avoid this
by compiling with --interface_enums_are_32_bit. The resulting object file can then be
linked with any other object file, without the linker-detected conflict that arises from
different enumeration type sizes.
Note
When you use this option, you are making a promise to the compiler that all the
enumerated types used in your external interfaces are 32 bits wide. For example, if you
ensure that every enum you declare includes at least one value larger than 2 to the power
of 16, the compiler is forced to make the enum 32 bits wide, whether or not you use
--enum_is_int. It is up to you to ensure that the promise you are making to the compiler
is true. (Another method of satisfying this condition is to ensure that you have no enums
in your external interface.)

2.1.94 --interleave
This option interleaves C or C++ source code line by line as comments within an
assembly listing generated using the --asm option or -S option.
