OK. Doesn't look like a big impact.
Thanks,

Gerd,
Sorry, gotta ask: does this make much difference in the size of the
compiled code? That's a constraint on many real-hardware X64 platforms,
especially for 32-bit code.
Quick test with OvmfPkg/OvmfPkgIa32X64.dsc (sec/pei ia32, dxe x64):
master branch:
FV Space Information
SECFV [11%Full] 212992 (0x34000) total, 23728 (0x5cb0) used, 189264
(0x2e350) free

(0x92048) free

So slightly more for 64-bit code.
take care,
Gerd
