Subject: [PATCH v2 03/16] StandaloneMmPkg: StandaloneMmCoreMemoryAllocationLib: Fix compiler warning
Date: Tue,  5 Jan 2021 10:59:22 -0800	[thread overview]
Message-ID: <MWHPR06MB3102DD127EF77696D54A2877F3D10@MWHPR06MB3102.namprd06.prod.outlook.com> (raw)
In-Reply-To: <20210105185935.3769-1-kun.q@outlook.com>

Assigning MmramRangeCount from MmCorePrivate (UINT64) to local variable
MmramRangeCount (UINT32) will cause compilation failure due to "warning
C4244: '=': conversion from 'UINT64' to 'UINT32', possible loss of data".
This changes defines local MmramRangeCount as UINTN type and adds type
cast before value assignment.

    - Changed variable type to UINTN and cast before assignments [Jiewen]
