Difference between x86, x32, and x64 architectures? In Linux terminology, i386 is the 32bit ISA, and amd64 is the 64bit ISA, also called x86-64 x86 is the superset, so x86-32 (i386) and x86-64 (amd64) are the two flavours of x86 x32 should not be used as a synonym for 32bit x86, because that term refers to something specific and very different (see the other answers comments) –
What is the difference between x86 and x64 - Stack Overflow The difference is that Java binaries compiled as x86 (32-bit) or x64 (64-bit) applications respectively On a 64-bit Windows you can use either version, since x86 will run in WOW64 mode On a 32-bit Windows you should use only x86 obviously For a Linux you should select appropriate type x86 for 32-bit OS, and x64 for 64-bit OS
Why is Windows 32-bit called Windows x86 and not Windows x32? x86 is the name of the architecture that it's built to run on (the name comes from a series of old Intel processors, the names of which all ended in 86, The first of which was the 8086) Although x86 was originally a 16-bit architecture, the version in use today is the 32-bit extension
x86 - What is an effective address? - Stack Overflow call 0x80000000 is a weird example, because x86 doesn't have an absolute direct form of a near call instruction, only call rel32 Do you mean a call from some address that results in EIP=0x80000000? Some assemblers would assemble it that way, but it's an unusual example
x86 64 - Assembly registers in 64-bit architecture - Stack Overflow For more information should read x86-64 and x86-64 calling conventions There's also a convention used in Plan 9 where All registers are caller-saved; All parameters are passed on the stack; Return values are also returned on the stack, in space reserved below (stack-wise; higher addresses on amd64) the arguments
What Does x64 and x86 Mean? - Digital Point This may sometimes be emphasized as x86-32 to distinguish it either from the original 16-bit x86-16 or from the newer 64-bit x86-64 (also called x64) Although most x86-processors used in new personal computers and servers have 64-bit capabilities, to avoid compatibility problems with older computers or systems, the term x86-64 is often used to
x86 - Assembly JLE jmp instruction example - Stack Overflow The x86 assembly uses a system of bit-flags that represent the result of comparisons The conditional jump instructions use these flags when deciding whether to perform the jump or not In your case you'd use the following two instructions:
