I don't see anything changed in this area, nor does it fail for me and many others (I haven't tried on amd64 personally though). What was the previous webkit-gtk version that built fine on that machine? Are you able to poke at it a bit more from your end? For example I can't spot what the value of memoryBits is when it fails assert, looks like python doesn't include that information in the output? :( Can you find out and poke at it a bit?
(In reply to Mart Raudsepp from comment #4) > What was the previous webkit-gtk version that built fine on that machine? None. This is basically a fresh gentoo install. But not fully true. This installation is about 1 year old and lacked now about 8 month of updates. But bare metal, not many packages installed. I emerged all updates and all went fine. But running full in ~testing. Now I wanted to install evolution as package, which wants to pull in webkit-gtk. > Are you able to poke at it a bit more from your end? > For example I can't spot what the value of memoryBits is when it fails > assert, looks like python doesn't include that information in the output? :( > Can you find out and poke at it a bit? Can you guide me a little bit here? I am not sure, how to get those information, but I am happy to try. Running the command "/usr/bin/python3.12 /var/tmp/portage/net-libs/webkit-gtk-2.42.4-r410/work/webkitgtk-2.42.4/Source/JavaScriptCore/wasm/generateWasmOpsHeader.py /var/tmp/portage/net-libs/webkit-gtk-2.42.4-r410/work/webkitgtk-2.42.4/Source/JavaScriptCore/wasm/wasm.json /var/tmp/portage/net-libs/webkit-gtk-2.42.4-r410/work/webkitgtk-2.42.4_build/JavaScriptCore/DerivedSources/WasmOps.h" reproduces the error manually.
(In reply to Mart Raudsepp from comment #4) > For example I can't spot what the value of memoryBits is when it fails memoryBits is 8 according to my added log output.
str(float(memoryBits))) = 8.0 str(float(math.log(memoryBits, 2)))) = 3.0 str(float(2 ** math.log(memoryBits, 2)))) = 7.999999999999999
-mfpmath=sse,387 is a bit unusual. Normally people just set sse. I think (but not 100% sure) that sse is implied by x86-64 but not 100% sure (for mfpmath purposes). Need to check.

At least compiling python with CFLAGS="-march=native -O2 -pipe" does not change anything for me while calling those math functions directly in the interpreter.
>>> 2 ** 3.0 7.999999999999999 >>> 2 ** 3 8 I am confused. Anyone an explanation or idea how to debug this further?
Created attachment 880969 [details] memorybits.patch This quick & dirty patch fixes it for me..
This doesn't even seem all that wrong to me. memorybits is an integer, etc. Could you file a PR to WebKit with the commit message or at least PR message explaining the problem and see what happens as feedback? Something like I did in https://github.com/WebKit/WebKit/pull/19242 perhaps. I remember to poke that now, so if they move it ahead, the commit will probably get rewritten. You can see the original formatting of the commit message they seem to want in net-libs/webkit-gtk/files/2.42.1-arm64-non-jumbo-fix.patch and there's https://github.com/WebKit/WebKit/wiki/Pull-Requests
Thinking on this further - I don't understand the purpose of the assert at all anymore. 2 ** x and log(x, 2) are inverse operations, barring IEE 754 math issues, this assert is guaranteed to succeed. The only case where it wouldn't pass is if python core math library is broken for one of them (unlikely), or the case you are hitting (very likely apparently; and it happens for the value of 5 for me, for example). This was added in https://github.com/WebKit/WebKit/commit/5ba399a221ec38686323efecb0043703bebb659e
https://bugs.webkit.org/show_bug.cgi?id=168836 So the purpose was to check that memoryBits is a power of 2, which the assert doesn't do?
(In reply to Mart Raudsepp from comment #12) > This doesn't even seem all that wrong to me. memorybits is an integer, etc. I still don't understand, why "3.0" produces a different result than "3". > Could you file a PR to WebKit with the commit message or at least PR message > explaining the problem and see what happens as feedback? Yes, I can do that. Fill on their Github? Do you would be willing to include such patch? Based on your example, I don't think, that there will be soon (tm) a fix.

It looks like, that all values with .0 seems to produece that, even 5. >>> 2 ** 5 32 >>> 2 ** 5.0 31.999999999999996 (In reply to Mart Raudsepp from comment #14) > So the purpose was to check that memoryBits is a power of 2, which the > assert doesn't do? What do you mean?
I do wonder, but with the following proramm, the glibc (?) also seems produce wrongly results. #include <stdio.h> #include <math.h> int main() { double x = 2.0; // base double y = 3.0; // power // using the pow() function double ans = pow(x, y); // printing the output printf("%.15f\n", ans); return 0; } $ ./a.out 7.999999999999999
