Question about WASM binary size using tot (musl 1.2.2)

[haberbyte]

The update to musl 1.2.2 did not cause any issues so far, just leaving this as a general observation, so 👍
So this issue could probably be closed if the following is expected.

I noticed my wasm binary size increases a bit with the latest musl changes.

On 2.0.34 builds i get:
-Oz: 148K
-O3: 220k

On tot builds i get:
-Oz: 153K
-O3: 230k

Given that this is just around 3% increase, is that within reason and expected?
It is still a bit disappointing and i wonder what parts are causing this.

[sbc100]

That is a size increase that we would like to avoid if possible.

I wonder if you can help track down the differences? Perhaps you could attach the different builds (with --profiling-funcs enabled if possible) or you can look at the differences using either twiggy or bloaty two tools that both allow comparison of wasm binaries side by side.

My hope is that there is some major chunk of libc that was not includes before and that is now being included and that wecan find a way to remove that dependency and reduce the binary size. Perhaps something like string formatting?

If i read this right, most of the size increase happens in the data section. Not sure how to further see what's going on there.
Interesting that exp2 and log shows up there, but i guess in terms size it is just a few bytes.

[sbc100]

Nice! Thanks for investigating. It does look like the data section is the significant change here. I imagine its related to the exp2 and log functions, perhaps they have a lot of associated table data?

We need to figure out a way to analyze the differences in the data section. I think there are some flags that will allow the final binary to contain a data section which is split in to individual named chunks, but I will have to get back to you on that.

In the mean time can have a look at where those "NEW" symbols are coming from by running passing -Wl,--trace-symbol=foo at link time. I imagine they are all related to exp and log2. Out of interest do you know why exp and log2 themselves are included?

[sbc100]

Building with -Wl,--no-merge-data-segments along with --profiling-funcs should produce a binary with each chunk of data in its own segment.

[sbc100]

Sadly it looks like bloaty doesn't break down the data segments, but you can use wasm-objdump -x -j DATA to dump the data segments and compare them.

[kripken]

If that doesn't work out, building small programs to test individual functions might help. I tried this now on exp2:

#include <math.h>
int main(int argc, char **argv) {
  return exp2(double(argc) / 3.1415921828);
}

The new version is actually 40% smaller. Reading musl's exp2.c it looks like it was completely rewritten.

[haberbyte]

Thank you for all that great input.

I used -Wl,--no-merge-data-segments and wasm-dis and compared each data section entry line by line. I then compared both builds.

Removing all entries that are on both sides, I am left with this result:

So in the old build there was half and tbl (which is not in the new build).
The new build has pretty large data sections for exp and log/log2.

I have no idea what half and tbl means here. Maybe the previous version somehow had one lookup table for exp/log/log2 data, whereas the new build somehow has one for each?

[haberbyte]

I can also see @kripken 's minimal example being around 40% smaller. I think it is because previously the tbl would have one large data section for pretty much all variants (exp, log, log2, ...).

I came up with another slightly more complex example which shows the increase:

#include <math.h>
int main(int argc, char **argv) {
  double num = double(argc);
  return exp2(num / 3.1415921828) + exp(num) - exp(-num) + log((1 + num) / (1 - num)) + log2(num);
}

With this I get around 11k (tot), and only 6.1k (old musl). It shows the same differences in the data section as with my obersation above.

[haberbyte]

I really have no idea what to do about this. I think within musl it boils down to these commits? bminor/musl@2a3210c bminor/musl@e16f7b3

Should provide a speedup for those log functions, does that generally translate to WASM as well?

[sbc100]

Thanks @haberbyte! I looks like you tracked it down. We will see what we can do about reverting that change or pehaps making it -O3 only.

[haberbyte]

I noticed that my observations can be simplified down to the log and log2 functions.
If I used the tot build and re-define both those functions to use their old version, then code size goes down 2KB in my project.

It is because exp/exp2 actually have size improvements, but the new log, log2 functions have large lookup tables now.
Maybe it is much faster that way? I could not prove this yet in the browser.

So maybe just "reverting" to system/libc/musl/src/math/log.c and system/libc/musl/src/math/log2.c ?
