Subject: [PATCH v4 04/20] StandaloneMmPkg: StandaloneMmCoreMemoryAllocationLib: Fix compiler warning
Date: Tue, 26 Jan 2021 11:46:54 -0800 [thread overview]
Message-ID: <MWHPR06MB3102873B87D7C3E00FC97763F3BC9@MWHPR06MB3102.namprd06.prod.outlook.com> (raw)
In-Reply-To: <20210126194710.2248-1-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.
