Per SMBIOS specs, The Type 0 BIOS Release Date is not a free form field but
must be specified in a US middle-endian format (mm/dd/yyyy), so make sure
we populate it accordingly by converting gcc's __DATE__ string. This is
required for platforms like Windows, that fail to parse the date otherwise.
Also, the system manufacturer should not be set to the same value as the
board manufacturer for the Type 1 strings, as, on the Raspberry Pi, this is
not representative of the actual manufacturer of the system, which is the
Raspberry Pi Foundation always.
It should be noted that we do not expect other compilers than ones using
a __DATE__ format similar to gcc's to be used for the foreseeable future.

So, this hunk is very neat, but nigh-on unreviewable.
I.e. we should defintely have it - but only once.
Could you break this up into some macros to go into some generic
helper lib? (I don't have a better idea than EmbeddedPkg TimeBaseLib,
but then that is already included in this module.)
Would you be OK to break that snippet out separate?

So you would like to have a set of macros like:
TIME_GET_BUILD_YEAR, TIME_GET_BUILD_MONTH, TIME_GET_BUILD_DAY in
TimeBaseLib.h that perform the above?
> Would you be OK to break that snippet out separate?
I think that's a good idea, especially as there is a potential
underlying issue with the __DATE__ format being specific to each
compiler, so we probably want to handle compiler detection somewhere,
preferably globally. For instance, the Intel compiler's __DATE__ format
would not work with the above, so I'll add some "vetted compiler"
detection for the macros.
The one thing I am not planning to look into is that, of course, as long
as you don't explicitly force the compiler to rebuild the sources where
these macros are used, then you may end up with a very obsolete build
date compared to the actual date of your last re-build. But that's
mostly because I don't think there exists a generic solution we can ise
to force recompilation of a file that uses a specific macro and also
because our main goal with these is to ensure that the Pi firmwares,
that we produce through AppVeyor, have a proper build date, and AppVeyor
builds are are always clean.
I'll send an EDK2 patch for the macros, and then a revised patch for
this when I get a chance.

Yes, thanks.
A friendly "your compiler probably won't know what to do with this"
#error would be friendlier than whatever non-GCC/clang would generate
on encountering this.

Yeah, that's fine.

Yeah, I really don't care about that.
Or the flipside, where someone modifies only (say) the Smbios
populating code a month after they built the rest of the tree.
If someone wants to put a *specific* date in, that should be done
manually, and if someone wants information on what was actually built,
they should put in the hashes of the top commits of all repositories
on PACKAGES_PATH as well as whether the state of each was clean.
Managing these bits through a rigid build process, like you are, is
very much valid.

Leif,
I was thinking the "Mmm dd yyyy” form of __DATE__ was standard. Maybe all we need is a compile time assert that checks the format?
6.10.8.1 Mandatory macros 1 The following macro names shall be defined by the implementation: _ _DATE_ _ The date of translation of the preprocessing translation unit: a character string literal of the form "Mmm dd yyyy", where the names of the months are the same as those generated by the asctime function, and the first character of dd is a space character if the value is less than 10. If the date of translation is not available, an implementation-defined valid date shall be supplied
It seems likely some compilers had an alternate version and chose not to change it and break existing code when the format got standardized. You would hope those compilers had some kind of optional strict ANSI flag or some such….
Thanks,
Andrew Fish

Just FYI, this is where I found that ICC might use something other than
Mmm dd yyyy:
https://software.intel.com/content/www/us/en/develop/documentation/cpp-compiler-developer-guide-and-reference/top/compiler-reference/macros/iso-standard-predefined-macros.html
However, I am seeing information that ISO/IEC 9899, as far back as C99,
does define __DATE__ as "Mmm dd yyyy", and I'm starting to think, since
the intel doc mentions an 11 character date, whereas "mm dd yyyy" is
only 10 chars, and it's supposed to highlight ISO compliance, that this
might be an unfortunate typo on the intel web site.
I don't have ICC installed at the moment, so someone may want to check
that ICC does indeed produce "Mmm dd yyyy".

If it turns out that the ICC documentation is only a typo, then I would
think that the need for an ASSERT might be less important.
