A basic question but I have trouble finding an answer. In assembly, disregarding which one, are the flags used to perform JE, JNE, JL, JG, JLE, JGE usually all cleared after the jump is done ?

CodePudding user response：

Conditional jump instructions do not set flags. So you can for example jump multiple times on the same comparison:

cmp eax, ecx
jl foo         ; if eax < ecx jump to foo
jg bar         ; if eax > ecx jump to bar
jmp baz        ; otherwise jump to baz
