Hi all,
what is the difference between incb %al and incb $i. According to my knowledge if you have some thing like "i++" (in c) then it is translated in to movw $i %ebx, incw %ebx, movw %ebx $i. My question, when I explicitly
give variable as operand to increment in assembly like "incb $i", then will that instruction execution cycle involves copying the contents from memory to register and increment and copy back to memory. Is this hidden
and Assembler takes care of it when writing to image file (machine codes or elf). Another question: Is incb %al is atomic operation, I mean, Is instruction execution cycle is interrupted by an event or a process.
Thank you.
Sri.
