Hi Mike,

Thanks for your review.

> Or it may be simpler to only check for 32-bit archs and assume all others are 64-bit.

I like this one. I will provide version 2 patch later.

Regards,
Nickle

Hi,

I see the following pattern in the RedfishPkg to cover all CPUs

    #if defined (MDE_CPU_X64) || defined (MDE_CPU_AARCH64) || defined (MDE_CPU_RISCV64)
    //
    // With GCC we would normally use SIXTY_FOUR_BIT_LONG, but MSVC needs
    // SIXTY_FOUR_BIT, because 'long' is 32-bit and only 'long long' is
    // 64-bit. Since using 'long long' works fine on GCC too, just do that.
    //
    #define SIXTY_FOUR_BIT
    #elif defined (MDE_CPU_IA32) || defined (MDE_CPU_ARM) || defined (MDE_CPU_EBC)
    #define THIRTY_TWO_BIT
    #endif

Can we apply the same pattern to OnigurumaUefiPort.h to define SIZEOF_VOIDP and add LOONGARCH64?

#if defined (MDE_CPU_X64) || defined (MDE_CPU_AARCH64) || defined (MDE_CPU_RISCV64) || defined (MDE_CPU_LOONGARCH64) #define SIZEOF_VOIDP  8 #elif defined (MDE_CPU_IA32) || defined (MDE_CPU_ARM) || defined (MDE_CPU_EBC) #define SIZEOF_VOIDP  4 #endif

Or it may be simpler to only check for 32-bit archs and assume all others are 64-bit.

#if defined (MDE_CPU_IA32) || defined (MDE_CPU_ARM) || defined (MDE_CPU_EBC) #define SIZEOF_VOIDP  4 #else #define SIZEOF_VOIDP  8 #endif


Thanks,

Mike
