Hi Brijesh,
Gerd's Jenkins CI caught a number of (most likely invalid)
[-Werror=maybe-uninitialized] issues with the new code. Do you have a
way to build the tree for IA32 with DEBUG_GCC49, evaluate the errors,
and send a series to suppress the warnings whenever they are invalid?
(Simply by assigning zero to the affected variables early into the
affected functions.)
Please note that the coding style requires a specific comment format for
such warning suppressions:
https://bugzilla.tianocore.org/show_bug.cgi?id=607
Of course, if some of these warnings happen to be correct, then the bugs
should be fixed. :)
Please find the first such error below.
Thanks!
Laszlo

I have been using GCC5, will try to setup GCC49 environment and provide
patches to fix this warning. Thanks for report.
