flagQuestion:
.L2:
cmpb %bpl, (%r12,%rax)
setb %cl
addl %ecx, %ecx
orb %cl, (%rbx,%rax)
addq $1, %rax
cmpq $100000000, %rax
jne .L2
flagQuestionWorkaround:
.L7:
cmpb %bpl, (%r12,%rax)
setb %cl
addl %ecx, %ecx
orb %cl, (%rbx,%rax)
addq $1, %rax
cmpq $100000000, %rax
jne .L7
flagIf:
.L12:
cmpb %bl, (%r12,%rax)
jnb .L11
orb $2, 0(%rbp,%rax)
.L11:
addq $1, %rax
cmpq $100000000, %rax
jne .L12
flagIfWorkaround:
.L16:
cmpb %bpl, (%r12,%rax)
setb %cl
addl %ecx, %ecx
orb %cl, (%rbx,%rax)
addq $1, %rax
cmpq $100000000, %rax
jne .L16
There is not much be done with flagIf really since it is a conditional
load/store.
