WebOct 25, 2024 · When a function is called, a new stack frame is created at the current esp location. A stack frame acts like a partition on the stack. All items from previous functions are higher up on the stack, and should not be modified. Each current function has access to the remainder of the stack, from the stack frame until the end of the stack page. Web6186 assembly syntax is based on x86-64 assembly, and like the x86-64, 6186 registers are 64 bits wide. However, the 6186 has a different set of registers. There are just five general-purpose registers, %ra, %rb, %rr, %rx, and %ry. (“[W]hen she tries to be deadly serious she is speaking under…constraint”.)

WebI can say that my dislike of x86 assembly comes from years of 68000 assembly. The difference in registers is one of the keys, for me. 68000 has simply 8 interchangeable data registers (all 32-bit) for operations to be used with 7 interchangeable address registers (also 32-bit).
