All integer registers are 32 bit. However, many of them have 16-bit or 8-bit subregisters. ax Low 16 bits ofeax bx Low 16 bits ofebx cx Low 16 bits ofecx dx Low 16 bits ofedx si Low 16 bits ofesi di Low 16 bits ofedi ...
1) 0x1(IL_ONLY) It means that assembly’s code is IL_ONLY that is it is pure IL thus it can be compiled to either 32 bit or 64 bit2) 0x2(32BIT_ONLY) means that assembly’s code must be compiled to 32 bit code and cannot be compiled to 64 bit....
⁵ It also means that the x86-32 pun of interpretingnopasxchg eax, eaxdoes not work in x86-64. The self-exchange zeroes out the high 32 bits as a side effect. The Windows debugger doesn’t realize this, and if you ask it to assemblexchg eax, eax, it encodes it as90, using the...
64-bit. The beauty of the ARM design is the processor can seamlessly swap from one mode to the other during its normal execution. This means that the decoder for the 64-bit instructions is a new design that doesn’t need to maintain compatibility with the 32-bit era, yet the processor ...
What's the problem (or question)? Surprisingly, x86 and x86_64 support for Android works just out of the box, the only issue is when running x86 (32-bit) lib on x86_64 (64-bit) emulators even tho it supports 32-bit Android 11 & 12 x86_64 emulator ...
Based on my understanding, the 32bit Windows API is commonly known as Win32. Meanwhile, 64Bit Windows API is called Win64. X86 and X64/AMD64 is referred to Intel/AMD ‘s CPU as Sheng pointed out. Win32 and X86 are defined into two different area. Win32 is major designed for desktop...

Could you please tell me differences between products for 32-bit/x86-64bit development, 32-bit development and x86-64bit development ?If I use the product for 32-bit/x86-64bit development on 32bit-OS can I compile codes which can run on 32bit-OS and 64bit-OS ?Thank ...
