> [ml64](https://learn.microsoft.com/en-us/cpp/assembler/masm/ml-and-ml64-command-line-reference?view=msvc-170) is set as the assembler for the Windows platform but is specific to the x64 platform. The [armasm64](https://learn.microsoft.com/en-us/cpp/assembler/arm/arm-assembler-command-line-reference?view=msvc-170) assembler should be used for Windows AArch64.
> 
> The -c and -Ta options are only valid for ml64 and -Ta can be removed from CompileFile.gmk (assembling for x64 works without it).
