Subject: [PATCH 04/25] Make sure stdint.h is always used with MSVC on
|
|
|
67650e |
ARM/ARM64, since all the versions of Visual Studio that support ARM or ARM64
|
|
|
67650e |
have that header. Without this, uint64_t would be defined to unsigned long,
|
|
|
67650e |
which is 32-bits in the Microsoft world.
|
|
|
67650e |
|
|
|
67650e |
Also fix aarch64/initplat.c so that memset/memcpy only apply
|
|
|
67650e |
to gcc. Otherwise MSVC throws an error for __SIZE_TYPE__.
|
|
|
67650e |
|
|
|
67650e |
Updating this patch to v2, since it turns out MSVC will also emit
|
|
|
67650e |
memset and memcpy intrinsics that we can use an implementation for.
|
|
|
67650e |
This is true for both ARM and ARM64.
|
|
|
67650e |
To make this work, I'm defining __SIZE_TYPE__ to UINTN if not
|
|
|
67650e |
already defined.
