Hi Gerd, others,
While working on the FdtLib migration to the submodule variant, I decided to
at least try to test build MicrovmX64 ... but I'm failing.
Both clang and gcc builds bail out at a GenFw invocation to generate
ResetVector.efi due to "Did not find any '.text' section". (Assert on line
938 of Elf64Convert.c.)
So I was hitting this also when doing dynamic stack cookies and trying
different ways to make ResetVector be okay being linked to the
null stack cookie lib. There is something that BaseTools doesn't do well
when ResetVector is linked against libraries, are you adding a library
linkage here (say a NULL lib applied globally)?
To fix this for stack cookies, my PR converts ResetVector to be
USER_DEFINED so that BaseTools will not link NULL libs against it.
Worth a shot seeing if making that change (you need to change the
RESETVECTOR rule in the FDF from SEC to USER_DEFINED also) makes
a difference. If this is not being caused by a null library
linkage, then I have no idea what is happening :).
