My gut feeling is that adjusting instruction sizes after you generated the machine code is just a bad idea. In theory it can be done, but I'd expect there's always a better solution to the problem it's trying to solve (e.g. delay the generation of the machine code, or just use pessimistically-sized instructions). === Stefan

Also, not really. For x86, Intel defines them, and other

That does not contradict what I wrote. Both assembly languages are
specific to the AMD64 architecture.

You are confusing builtins with intrinsics. Builtins are defined by
the compiler. E.g., __builtin_addcll() is supported by clang on all
architectures, but is not supported by gcc. By contrast, the
intrinsic _addcarry_u64() is defined by Intel and is supported on gcc
and clang (and, I guess icc, and maybe others), but only when
compiling for AMD64.

Essentially, it is C89, but:
Has // style comments;
Has "long long" and similar.
Vs, plain C89, where one only has
/* comment */
long (32-bit).
More or less what most versions of MSVC supported between ~ 2000 and
2013 (VS2015 added some C99 stuff).
Still required if one wants to be able to target Win2K or WinXP, as the
versions of the compiler that support these only support C95.
Much prior to this, and it drops to C89; but mostly only really matters
if one wants to compile code on Windows 3.11 or similar.
Though, there is the other option of (for older Windows versions, or
real-mode MS-DOS) using Borland C instead.
OTOH, for some other targets there are compilers like SDCC or CC65,
which IIRC lack support for "long long", but I sorta suspect there is no
practical reason to want to run this code on these targets (well, except
maybe for novelty of running Decimal128 math on a 6502 or something...).
I did set a limit of mostly ignoring 8/16-bit machines.

Though, probably going to be a good long time before MSVC gets these...
For now, if one wants 128-bit math, it is mostly via wrapper structs and
explicit function calls.
Could work OK. Except that shift-and-subtract division is slow.
At present, I lack a good/efficient way to break a 128-bit integer into
10e9 chunks (if using the 10e9 divider, this sucks).
Can note that GCC seemingly doesn't support 128-bit integers on 64-bit
RISC-V. Also, doing 128-bit arithmetic on RV64 kinda sucks as there is
basically no good way to do extended precision arithmetic (essentially,
the ISA offers nothing more here than what C already gives you).
Like, you can do what is essentially:
c_lo = a_lo + b_lo;
c_hi = a_hi + b_hi;
if((c_lo<a_lo) || (c_lo<b_lo))
c_hi++;
But... This kinda sucks...
...
Though, can at least do multiply by 10e9 and similar fast-ish via
fixed-patterns shift-and-add. In premise, could use the "toothpaste
tube" strategy (multiplying by powers of 10 to squeeze digits out the
top), but would need to figure out the appropriate magic number to
multiply against the Int128 value (via a 128*128->256bit multiply,
keeping high result) to be able to get the value scaled correctly to use
this algo (this multiply also being an area of concern).
Ironically, this strategy is more directly relevant to Binary128 or
similar, as in this case, Binary128 will already have the mantissa bits
scaled in the correct way (after normalizing to remove the integer part).
I had experimented with trying to "crack" groups of digits off the
low-end, eg:
while(arr[0]>=1000000000)
{
arr[0]-=1000000000;
Inc(arr+1);
}
But, alas, it was seemingly not so easy, and this does not give the
correct results.
It is possible to use an approach similar to double-dabble (feeding in
the binary number 1 bit at a time, and adding the decimal vector to
itself and incrementing for each 1 bit seen). But, alas, this is also
slow in this case (takes around 128 iterations to convert the Int128 to
4x 10e9). Though, still slightly faster than using a shift-subtract
divider to crack off 9 digit chunks by successively dividing by 1000000000.
Or, maybe make another attempt at Radix-10e9 long division and see if I
can get it to actually work and give the correct result.
Though, might be worthwhile, since if I could make the DIV operator
faster, I could claim a result of "faster than IBM's decNumber library".
Even if in practice it might still be moot, as it is still impractically
slow if compared with Binary128.

What makes you think so? It has certainly worked every time I tried
it. E.g., Gforth's "configure" reports:
checking size of __int128_t... 16
checking size of __uint128_t... 16
[...]
checking for a C type for double-cells... __int128_t
checking for a C type for unsigned double-cells... __uint128_t
That's with gcc 10.3.1

You only need to check for c_lo<a_lo (or for c_lo<b_lo), they will
either both be true or both be false.
Here's 128-bit arithmetic on RV64GC (and very similar on MIPS and
Alpha):
add a4,a4,a5
sltu a5,a4,a5
add s8,s8,s9
add s9,a5,s8
RISC-V (and MIPS and Alpha) becomes relly bad when you need add with
carry-in and carry-out (five instructions).

Seems so. Testing again, it does appear to work; the error message I thought I remembered seeing, instead applied to when trying to use the type in MSVC. I had thought I remembered checking before and it failing, but it seems not. But, yeah, good to know I guess. As for MSVC: tst_int128.c(5): error C4235: nonstandard extension used: '__int128' keyword not supported on this architecture MSVC doesn't recognize __int128_t at all. Where: """ Microsoft (R) C/C++ Optimizing Compiler Version 19.44.35219 for x64 Copyright (C) Microsoft Corporation. All rights reserved. """ ... Either way, it falls outside the scope of the C dialect I was targeting here; and at least one of the compilers I am using still doesn't support it. It is possible though I could still have an ifdef for targets that have this type. Misc: Decided to post a graph generated by BGBCC: https://x.com/cr88192/status/1989134230648156378/photo/1 It shows the relative distribution of constants as recorded by the compiler. I had considered trying to feed the data into LibreOffice, but the interface is awkward enough that it became less effort to just add graph-drawing code to my compiler. Nevermind if graph-drawing technically falls outside of the compiler's scope of responsibilities. Partly this was to make a case for why it makes sense to have 33-bit immediate values, but not bother so much with slightly larger values. Basically, one has to cross a big gap of "mostly nothing" before reaching a modest spike up near the 64-bit mark. Note that Y axis is in Log 2 (it was either this or mask off 0). Granted, there are other possible ways to graph this. This particular example mostly resulted from compiling Doom. >> Also, doing 128-bit arithmetic on RV64 kinda sucks as there is >> basically no good way to do extended precision arithmetic (essentially, >> the ISA offers nothing more here than what C already gives you). >> >> Like, you can do what is essentially: >> c_lo = a_lo + b_lo; >> c_hi = a_hi + b_hi; >> if((c_lo<a_lo) || (c_lo<b_lo)) >> c_hi++; > > You only need to check for c_lo<a_lo (or for c_lo<b_lo), they will > either both be true or both be false. > OK, I wasn't sure here. > Here's 128-bit arithmetic on RV64GC (and very similar on MIPS and > Alpha): > > add a4,a4,a5 > sltu a5,a4,a5 > add s8,s8,s9 > add s9,a5,s8 > > RISC-V (and MIPS and Alpha) becomes relly bad when you need add with > carry-in and carry-out (five instructions). > OK. Still not great. On my ISAs, it is one of: ALUX R10, R12, R10 //if supported Or(XG1/XG2): CLRT ADDC R12, R10 ADDC R13, R11 Never got around to adding a 3R ADDC (and as-is is basically the same idiom as carried over from SH-4). On XG3, the latter is no longer formally allowed (partly for consistency with RISC-V), but nothing technically prevents it (support for SR.T and predication was demoted to optional, and currently not enabled by default). Could maybe still make sense to add a 3R ADDC though at some point, as it could help with 256-bit arithmetic (and 256-bit stuff is not addressed by ALUX). Or, maybe even ADDCX, for 128-bit ADD-with-Carry?... Though, did randomly remember a video I saw recently talking about how, if the dinosaurs were still around, it is very unlikely human-like creatures would have emerged. The idea was that creatures would rise to the peaks of the "fitness landscape" and eventually get stuck there, and it would have created a world where basically there would have been no paths that would have favored anything human-like emerging (and it is unlikely that any creatures would descend back into the "valleys" to reach other possible peaks in the landscape). Does make me wonder if similar ideas could apply to things like software and CPU architecture. Like, possible higher peaks that could potentially lead to significant improvements in performance or capability, but nothing can reach them as there is a "valley of suck" in the way. Well, there are always random detours that seem to point this way, such as with things like trinary logic, analog electronics, stochastic logic, etc. Which have interesting properties but are, strictly speaking, inferior to what we have now. Say, for example, it does seem like Trinary could be used to drive more data over a differential signaling bus, say: 00: 0 (Z) 01: +1 (P) 10: -1 (N) 11: Hi (H, idle state) Then, say, one can drive the equivalent of 9 bits of data in 6 clock cycles, with enough additional states that they could be used either for error-detection or DC balancing (could in concept do something like NRZ where there would often be multiple possible paths to encode every possible bit sequence and the encoder chooses the path that maintains the best balance and avoids getting stuck in a non-changing state for too many cycles). Say, for example, every 2 trits encodes 3 bits, but then leaves one redundant option. If one assumes that a scheme similar to NRZ is used, then in cases where one gets a long run of 0 bits or similar, then it can use a redundant zero encoding such that "on the wire" it still sees a state transition, maybe: ZZ: 000, ZP: 001 ZN: 010, PZ: 011 PP: 100, PN: 101 NZ: 110, NP: 111 NN: 000 Though, if the mapping rotates after every odd trit, then it becomes statistically unlikely that and significant DC-imbalance could arise (but would make NRZ redundant). Or, if it does arise somehow, the encoder could stick some idle-state pulses into the mix as well (possibly understood as repeating the prior trit). So, say, ZH/PH/NH being equivalent to ZZ/PP/NN but with an extra transition, vs HH being the true idle state. Well, unless going through a coupling transformer (like in Ethernet) where ZZ/HZ would be ineffective (but would be saved by a ZZ/NN transition). But, this seems like one of those things that presumably someone would have already thought of it?... ...

More or less it seems.
This leaves, apparently:
MSVC: Maybe once had it for IA-64, but nowhere else;
GCC: Supported, but lacks a printf modifier for it in glibc.
Clang: Supported, but lacks support for 128-bit integer literals?...
BGBCC: Supported, with literals and 'I128' printf modifier.
Where, 'I128' is similar to 'I64' in MSVC,
as for a long time they also lacked the 'll' modifier and similar.
ISA's:
X64: Can build manually via register pairs (any two registers), ADD+ADC
allows for 128-bit in 2 instructions;
Many 128-bit ops can be built using flags bits;
ISA supports widening multiply and narrowing divide, though typically
with hardwired registers.
XG1/XG2:
CLRT+ADDC+ADDC
Theoretically arbitrary, BGBCC only uses even pairs;
CLRT needed to clear the SR.T flag;
Normal ADD does not modify SR.T.
Could maybe be better if there were a 3R ADDC variant,
and maybe a carry-out only variant (so no CLRT was needed).
ADDX
Even pairs only, single instruction.
XG3:
Support for SR.T was demoted to optional,
half the encoding space goes unused if predication isn't used though.
Could bit a "better" RV-C in there (*1).
ALUX instructions could be used, also optional.
Otherwise, it is left in a similar situation to RISC-V here.
*1: Noted before that if one tweaks the design of RV-C some:
Makes Imm/Disp fields smaller;
Replaces Reg3 with Reg4 (X8..X27);
...
It is possible to get an set of 16-bit ops that both use less encoding
space and get a better average hit rate than the existing RV-C ops
(mostly by not trying to do Imm6/Disp6 in said ops; and only using Reg5
on a few instructions).
However, IMO, makes more sense to support RV-C for binary compatibility,
than for the encoding scheme not being "kind of a turd".
However, "XG3 sub-variant that drops predicated encodings in favor of
re-adding a new/different set of 16-bit encodings" was not a
particularly attractive option.
For where it makes sense to use XG3 though, likely it makes sense to
allow/use SR.T and the predicated encodings, which can still offer a
small but non-zero performance benefit (even if debatable if it is
something that is worth spending half of the encoding space on).
I did also experimenting with allowing a few blocks to be used for
pair-encoded ops. One other possibility could be some additional
unconditional-only instruction blocks (but, these would be N/E in XG1/XG2).
One possibility could also be an "XG3 Lite" subset:
Likely unconditional only, and also disallows RISC-V encodings.
Or, IOW:
...xx00 Disallowed
...xx01 Disallowed
...xx10 Allowed
...xx11 Disallowed
Could maybe make sense if I wanted a core on a smaller FPGA.
However, there isn't that much incentive to go for much smaller than the
XC7S50 with this, and for current use-cases that could involve an XC7S25
or XC7A35T, you kinda really want to try to maximize code density
(mostly because the currently available dev-boards with these FPGAs tend
to lack external RAM).
The Intel/Altera chips tend to always have integrated ARM cores;
Boards with Lattice FPGAs (probably ECP5 or similar in this case, *)
tend to be obscure and overpriced (even if theoretically the FPGAs
themselves are cheaper).
*: One is harder pressed to make a non-trivial CPU core that fits into
an ICE40.
Though, one other possibility being trying to again implement dual-core
on an XC7A100T, but possibly sharing FPU and SIMD between the cores (may
or may not be viable).
In this case, there would be a mechanism such that inter-core interlocks
could trigger to disallow both cores trying to access the FPU or SIMD
unit on the same clock-cycle. Though unclear how this could interact
with pipeline stalls (would ideally want both cores to have independent
pipelines; but then one needs to arbitrate things such that both units
get their results at the expected clock cycle, ...).
Though, to that end, may also make sense to consider going to a
dual-issue superscalar with 4R2W register file.

In "Extending General-Purpose Registers with Carry and Overflow Bits" <http://www.complang.tuwien.ac.at/anton/tmp/carry.pdf> I discuss adding a carry bit and overflow bit to every GPR of an architecture. To make it concrete how that would affect the instruction set, I propose such an instruction set extension for RISC-V. It contains the instructions addc rd, rs1, rs2 which adds the carry bit of rs2 to the 65-bit (i.e., including the carry bit) data in rs1. The other instruction I proposed is bo rs1, rs2, target which branches if the overflow bit of rs1 or rs2 are set (why check two registers? Because it fits in the RISC-V conditional branch instruction scheme). A 256-bit addition (d1,c1,b1,a1)+(d2,c2,b2,a2) would look as follows add a3,a1,a2 add b3,b1,b2 addc b3,b3,a3 add c3,c1,c2 addc c3,c3,b3 add d3,d1,d2 addc d3,d3,c3 with 4 cycles latency. addc is limited to having two source registers (RV64G instructions all have this limit). The decoder could combine a pair of add and addc instructions into one three-source macro-instruction. Alternatively, one could add a three-source instruction addc4 (VAX-inspired naming) to the instruction set, and maybe include subc4 as well. >Does make me wonder if similar ideas could apply to things like software >and CPU architecture.

Network effects favour incumbents, and network effects are strong in computer architecture for general-purpose processors. Sometimes I think that it's a miracle that we have seen the progress in computer architecture that we have seen: 1) We used to have a de-facto standard of 36-bit word-addressed machines (ok, there were character-addressed and digit-addressed machines at the time, too), and it has been superseded by a standard of 8-byte-addressed machines with word size 16 bits, 32 bits, or 64 bits. The mechanism here seems to have been that most of the 36-bit machines had 18-bit addresses, and, as Gordon Bell wrote, running out of address bits spells doom for an architecture. 2) At one point (late 1980s) it looked like big-endian would win (almost all workstations at the time, with DEC stuff being the exception that proved the rule), but eventually little-endian won, thanks to PCs (which inherited the Datapoint 2200 byte order) and smart phones (which inherited the 6502 byte order). Another, less surprising development is that trapping on unaligned accesses is dying out in general-purpose machines. In the 1980s and 1990s most architectures trapped on unaligned accesses. But that's a "feature" that almost no software relies on, so there are no network effects in its favour. OTOH, porting software from an architecture that performs unaligned accesses is easier to architectures that perform unaligned accesses. So eventually all general-purpose architectures have converted to performing unaligned accesses, or died out.

My point was that 1-bit of carry is not enough when MUL and IV need
64-bits--and that is the issue CARRY addresses. In addition multi-

For multiplication, instruction sets provide widening multiplication,
with one instruction producing two words, or with instructions that
produce low and high words. These days I would consider doing this
with SIMD registers, which would allow the double-width result in a
single register; that was an option for ARM A64, but they chose to use
GPRs and low and high instructions; strange. For AMD64, it was not
really an option (it continued with the multiplication instructions
that existed in IA-32); for RISC-V, it also was not an option, as its
M extension was designed long before the V extension.
For division, again double-width by single-width division has been
designed into several instruction sets and is a good stepping stone
for multi-precision by single-width division. Again, using SIMD
registers appears to be a way to reduce the number of register
accesses in the instruction.
The double-width->single-width shift looks like a good stepping stone
for multi-precision shifts. It's unclear to me why Intel included two
instructions for that purpose: SHLD and SHRD.

Actually, the way to go would be to unroll by a factor of two, with
the n registers and m registers switching role between the
sub-iterations. If you do not want to go there, you would not use a
RISC-V mov, because that expands to an instruction that destroys the
carry bit. Instead, you would use an idiom (e.g., or rm, rn, zero)
that transfers the carry bit.

I thought up to now that the stuff covered by CARRY means
(R12,R13) = R8+R9+R12
(R12,R14) = R10+R11+R12
(R12,R14) = R14+R13+R12
Which would be wrong for the desired operation. What is needed
instead is, maybe
(R12,R14) = ((R8+R9)+(R10+R11))+R12
My expectation is that with CARRY, something functionally equivalent
might be implemented as:
MOV R12,#0
MOV R15,#0
MOV R16,#0
VEC R7, {}
... LDDs
CARRY R12,{{IO}}
ADD R13,R8,R9
CARRY R15,{{IO}}
ADD R14,R10,R11
CARRY R16,{{IO}}
ADD R14,R14,R13
STD ...
LOOP ...
ADD R15,R15,R16
ADD R12,R12,R15

I think I've said so before, but it bears repeating: I _really_ love CARRY! It provides a lot of "missing link" operations, while adding zero extra bits to all the instructions that don't need it. That said, if I had infinite resources (in this case infinity == 4 sources), I would like to have an unsigned integer MulAddAdd like this: (hi, lo) = a*b+c+d simply because this is the largest possible building block that cannot overflow, the result range covers the full 128 bit space. From what you've taught us about multipliers, adding one (or in this case two) extra inputs to the adder that aggregates all the partial multiplication products will be close to free in time, but the routing of the extra set of inputs might require an extra cycle?

Alas:: the best CARRY can do is:

In the integer case, there is no rounding.
In the FP case, FMAC is not part of the CARRY applicable OpCode space.

What latency?

With the carry in the result GPR, you could achieve that as follows:
add t,c,d
umaddc hi,lo,a,b,t
(or split umaddc into an instruction that produces the low result and
one that produces the high result).
The disadvantage here is that, with d being the hi of the last
iteration, you will see the full latency of the add and the umaddh.

1 multiply latency {likely 4 cycles} but more importantly no more cycles
than
c = a*b;

You can do this at the added latency of ADD.

CARRY is an instruction-modifier it is not "executed" {or you can
consider it "executed" in the DECODE stage of the pipeline.} The
subsequent MUL takes no more time CARRY or no-CARRY.
