But is does matter:: when i == NEGMAX:: i == -i ?!?!?
In what kind of arithmetic world does -i == i ???
{maybe not enough though}

And you mean "int8_t i = 0x80;" anyway. 0xff is -1 on an 8-bit two's complement machine - and then its negative is 1. > signed char j = -i; > > if( i == j ) // WTF > > NEGMAX == -NEGMAX in 2-s complement. > > I submit this is a lot stranger than having 2 zeros. > And that is why signed integer overflow is undefined behaviour in C. When you have overflows, there are no correct answers - no answers that make mathematical sense. Once you say that signed integer overflow is UB, and your code does not execute UB (or does not care what happens if it does), then signed integer types in C obey nice mathematical laws like "-i != i" except for when "i" is 0, and "a + b > a" if "b > 0". Two's complement wrapping is wonderful for tasks such as implementing multi-word arithmetic, and for efficient hardware implementations - but not at a higher level.

I think that's certainly _part_ of it. DEC made the LINC, which was a one's complement machine... or, rather, it made kits with which researchers could make their own LINC computers. Later on, they made the PDP-5, largely for process control, which was two's complement. Later, this caused some extra complexity when they made the LINC-8 and its successor the PDP-12, which combined their PDP-8 (almost compatible with the PDP-5) and the LINC in one box. They also made an 18-bit computer, the PDP-4 (which had compatible successors in the PDP-9 and PDP-15) which had a set of one's complement instructions and an additional set of two's complement instructions. I guess that let those machines act as bridges between hardware which was either one way or the other. That case illustrates what a mess this was for a while. Most other makers chose to go either one way or the other. IBM went with sign-magnitude on the IBM 704 and its successors. Although the index registers, which presumably didn't matter as much, were two's complement. The IBM System/360, though, was sign-magnitude for floating point (like nearly everyone else) but two's complement for binary integers. (Decimal integers were sign-magnitude still.) In my opinion, it was the decision by IBM to make the switch which legitimized sign-magnitude. Just as DEC switched from making 18-bit, 36-bit, and 12-bit computers to the 16-bit PDP-11 after the System/360 (and the PDP-11 also had general registers) IBM, being the biggest computer company, was hugely influential. People designing computers tended to copy whatever IBM did. After the IBM 704, computers from a whole bunch of manufacturers looked like the IBM 704 in many ways. Some of those ways aren't just IBM influence; using six-bit characters because only upper-case printing was needed for a computer was just a result of the technology of the day. As costs came down, and as IBM went to the eight-bit byte mostly because packed decimal four-bit digits fit in it efficiently, people started considering letting computers use lower-case. So once IBM used two's complement, and the roof didn't fall in, people woke up and realized that one's complement was a waste of time. John Savard

Their earlier 18-bit machine, the PDP-1, despite having a five-bit opcode field (unlike the four-bit opcode field of the PDP-4 and its successors) was one's complement only. John Savard

The DEC Computer Engineering book says that the PDP-4 was designd to be a lower cost PDP-1, 5/8 of the performance for half the cost. They added two's complement arithmetic because the users wanted to do multiple precision and floating point arithmetic with more than 18 bits which is a lot easier to do in two's complement. It also added a "link" bit to hold the carry out of the accumulator, and instructions to test it so you could do something like this for a two word addition CLA A / low part TAD B / carry is in the link bit DAC C CLA A+1 / high part SZL / skip on zero link IAC / add 1 to AC if there was a carry TAD B+1 DAC C+1 The PDP-5 and -8 also had a link bit. -- Regards, John Levine, johnl@taugh.com, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly

On Alpha you needed to play tricks with predicated instructions, afair you had two forms of ADD, one that just added two registers and one that did the same plus an extra increment which represented an incoming carry. Even on x86/x64 you get into similar situations when you need to add multiple parts together, it is easy to get stuck with long manual carry chains.

No, Alpha is just like MIPS and RISC-V. For RISC-V: add tmp1, carry, summand1 sltu carry1, tmp1, summand1 add sum, tmp1, summand2 sltu carry2, sum, tmp1 add carry, carry2, carry1 Alpha has no predicated instructions apart from a conditional move and no addition with an extra increment. What you describe reminds me of IA-64; it certeinly selects between a+b and a+b+1 with predication, but I don't remember how it gets the carry-out into a flag. >Even on x86/x64 you get into similar situations when you need to add >multiple parts together, it is easy to get stuck with long manual carry >chains. Not sure what you mean here. If you do it the conventional way, you certainly have a carry chain of n-1 carries if you add two n*64-bit numbers; so you have n dependent adds involved. If you want more parallelism, Michael S has presented a technique here that allows breaking such a chain into pieces, but it increases the number of instructions to execute, so you probably want to have a chain of a few such dependencies before you break one. Alexander Yee has implemented Kogge-Stone addition in AVX-512, but found that the variant that uses mask operations it is slower on Skylake X than the conventional way. On AMD processors with AVX-512, it looks better. He also has a longer sequence that avoids the mask instructions and is faster on Skylake X. If you want to have more addition chains at the same time, as in m1+m2+m3, or m1*m2 (which needs two addition chains in a conventional implementation), AMD64 gives you two carry chains with ADX (which, interestingly, is not included in x64-64-v4, even though ADX is included in all processors that have all of the features of x64-64-v4). Once you need three carry chains, you are out of luck with AMD64. >Possibly the best primitive is MAA (Mul Add Add) representing > > (sumlo, sumhi) = muladdadd(f1, f2, a1, a2); > >since this can never overflow the two-element result? It is useful for m1*m2, but not for addition. With one carry flag (e.g., ARM A64), a primitive (lo, hi) = muladd(f1,f2,a1) or alternatively (li, hi) = muladd_carry(f1,f2,a1) would already be helpful and would be a little closer to the usual instruction formats. A disadvantage of implementing all these primitives for multiplication as instruction is that in any usual implementation of such instructions it adds the latency of the multiplication on the whole chain, whereas you can avoid that if the addition is separate. BTW, the Alpha/RISC-V approach is not as bad for implementing muladdadd as it is for add with carry-in and carry-out; e.g., if you want to minimize the latency from a1 to hi (because hi will become the a1 in the next limb): mulhu hi, f1, f2 mul lo, f1, f2 add lo, lo, a2 sltu carry, lo, a2 add hi, hi, carry add lo, lo, a1 sltu carry, lo, a1 add hi, hi, carry That's three cycles of latency. Of course, AMD with ADX is better: # a1co = a1-C-O # f1 is in rdx; AT&T operand order mulx f2, lo, hico adcx a2, hico adox a1, hico # hi = hico+C+O The addition of C and O happens in the next limb. So here we have a latency of one cycle from one limb to the next (if C and O are independent, as in Intel P-cores). - anton -- 'Anyone trying for "industrial quality" ISA should avoid undefined behavior.'

Mea Culpa! You are correct, I mixed up Alpha and IA-64.

It's just a flip-flop. The carry out becomes the new carry in after the next clock. There is no problem at all to propagate this over as many additions as you want As far as I know, all machines these days have an ADD with carry as a single instruction. Jeroen Belleman

Keep in mind that this computer was designed in 1962, built out of individual transistors soldered onto PC cards, and had 1K, 4K, or 8K 18 bit words of core memory. Of course more modern instruction sets are better. The point is that they understood that two's complement made multiple precision arithmetic a lot easier than one's comp or sign-magnitude, and they added a testable flag where they stored the carry. As the manual said about the tad instruction: 2's complement add. The C(Y) are added to C(AC) in 2's complement arithmetic. If there is a carry out of bit 0 of the AC, the Link will be set to 1. This feature is useful in multiple precision arithmetic. -- Regards, John Levine, johnl@taugh.com, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly

Turning TAD into TADC (with carry-in) would only have require to use a full adder instead of a half-adder for the lowest bit of the adder and put a wire from the link bit to the carry-in of that full adder. And given that it also has a ones-complement addition, the lowest bit probaly already uses a full adder for the end-around-carry (another reason would be that it may have a narrower (maybe even 1-bit) adder that is used in multiple rounds for a full-width addition, like the original Nova). So the only cost would be to mux the link bit with the end-around-carry depending on the instruction, rather than just masking the end-around carry depending on the instruction. Doing the multiplexing with a wired-or would require one additional gate and two wires; even for a cheap model, the incremental cost would be tiny. The 6502 was also designed to be extremely cheap, and it was designed to be so cheap that it does not even support 16-bit-wide ALU operations despite having 16-bit addresses, but it does include carry-in. They could have shaved off a few more transistors for having only a half-adder for the lowest bit of the ALU, but did not. As for 1962 and more modern instruction sets being better, I think that, yes, they suffered from not having that many good examples to look at, while 64 years later I can point at the 6502 as an example that did this aspect better, while being designed for very low cost, too. S/360 does not have an add with carry-in, either, and IIRC it took until S390 (or S390x?) for them to add it, while microprocessors, having learned the lesson with the 8-bit architectures, usually included add with carry-in and carry-out from the start (with the notable exceptions of MIPS and its descendants). Looking at the PDP-11, it seems to me that again, it supports double-precision arithmetic with the ADC and SBC instructions, but not multiple-precision arithmetics: It splits the add with carry-in into two instructions: ADC and ADD (ADC only adds the carry), but the carries of the two instructions have to be combined with a complex sequence of instructions in order to achieve an add with carry-in and carry-out. The VAX has ADWC, which is a full add with carry-in and carry-out, so the minis eventually learned the lesson, shortly after the micros, and a lot of years before the mainframes. - anton -- 'Anyone trying for "industrial quality" ISA should avoid undefined behavior.'

That's what I meant. I only recently learned that the Z80 also has a four-bit ALU, making two passes for an 8-bit addition. I *had* wondered why the 6502 got similar performance at 1 MHz as the Z80 at 3 to 4. -- This USENET posting was made without artificial intelligence, artificial impertinence, artificial arrogance, artificial stupidity, artificial flavorings or artificial colorants.

It gives examples, e.g. INC B takes 1 M-cycle consisting of 4 T-states. On the 6502 INX and INY take 2 cycles. ADD HL, DE takes 3 M-cycles consisting of 11 T-states. The 6502 does not do reg-reg adds and does not have 16-bit registers, but the minimum would be something like: #L in A # C is known to be clear, otherwise preprend CLC at 2 cycles adc E # E in zero page sta L lda H # H in zero page adc D # D in zero page #H in A with a total of 12 cycles. INC (IY+d) takes 6 M-cycles and 23 T-states On the 6502 this might be either # IY in x, but x can only hold 8 bits INC d,x # 6 cycles with d in zero page, 7 otherwise or, if that's too restrictive, # IY in zero page # C is known to be clear, otherwise preprend CLC at 2 cycles ldy #d lda (IY),y adc #1 sta (IY),y with a total of 14 or 16 cycles. So even this sequence beats the Z80 in terms of cycles (but not by a factor of 3 or 4). The restricted version beats it by a factor of 3-4 in cycles. So if the 6502 programmer could arrange to use of INC d,x for INC (IY+d) often, and the Z80 progammer could not make use of ADD HL,DE often, the factor of 3-4 in cycles is possible. However, my impression is that there is a lot of cherry-picking in such reports. For a more recent and, I think, more balanced report, but still using only one particular task popular in benchmarking during the period, <https://www.ele.uva.es/~jesus/sieves/update.pdf> reports a factor 1.9 more cycles on the Z80 than the 6502 (so a TRS-80 Model I (1.78MHz Z80) would perform very similar to a PET or Apple II (1MHz 6502)); however, 4MHz became a more common clock rate for Z80 systems, while even the 1982-vintage C64 still has only 1MHz. More on the sieve comparison can be found on <https://www.ele.uva.es/~jesus/sieves/sievetst.html>. This also points to an earlier paper by Jesus Arias <https://www.ele.uva.es/~jesus/sieves/onthe6502.pdf> where the benchmark programs were less optimized, but the relations between 6502 and Z80 are similar. But the interesting thing for an earlier discussion here is that he also compares to the BN16, a 16-bit RISC processor he designed. It takes 7678 transistors in CMOS, and he estimates that it would be 3000-4000 transistors in NMOS, which would be similar to the 6502. With that the task takes a similar number of executed instructions as on the 6502, but many fewer clock cycles. Apparently the BN16 uses a 16-bit data bus (it achieves 1.11 CPI), so it would be too expensive to use at the time. Designing it for an 8-bit data bus would take some more transistors and increase the CPI to 2.11 (with the same instruction set), but that's still better than the 6502's CPI of 3.04. Maybe one could design a CPU with lessons from RISCs, but also including 8-bit-wide instructions for a better CPI and smaller programs, without too many additional transistors. - anton -- 'Anyone trying for "industrial quality" ISA should avoid undefined behavior.'
