Ai like talking to people too, i am just completely wooden outside of servers as some people in this server may know
Afor reasons i cant describe
Aunfortunately half 10pm is not quite the right time lmao
KSame I'm omw into bed it's midnight
KBut 5min voice channel
Aaaaand discord fucked my audio driver, excellent
Mi leave for 5 minutes to make some food
POk I was drifting off to sleep when I thought of an issue: implicit casts. The destination side of the operator needs to be a PtrType<T> where T is actually T, which means there’s no way we can do typed implicit casts
PGoing back to sleep now but @ me in the morning
Poh also don’t forget to check whether Span as Ptr2D actually works

This is an issue that someone (graphite?) raised on Discord but didn't file here. The bool types in C/C++ are kinda weird and can not match, especially when put back to back. webgpu.h shouldn&#...
Lwe currently generate invalid bindings when using stdbool beacuse stdbool is bad
L_Bool in C iirc has an undefined size
KI don't really understand the edge case here
KLooks like there's already a PR to change it to be uint instead. Not sure it's worth fixing on our side
LPR is not finished
Lits not worth fixing on our side, as i had stated on github https://github.com/dotnet/Silk.NET/issues/1593#issuecomment-1664580272
KYeah saw that
Misn't a register always at least 4 bytes
Mmeaning using an int is fine
Ldoesnt work that way for structs
Mstructs are usually padded to the word
Ltheir fields arent
Leither way how big
_Bool is is likely different from MSVC -> GCC so i dont trust itMwhat size is the bool in the chromium impl
Lits stdbool
_Bool, so undefined by the C99 specMwhat compiler does chromium use
Mclang i think right?
Lit can use multiple
Lalso this is unrelated to chromium
LDawn is whats important
Land thats a separate component linked in
Lwgpu is also important
Land thats Rust
Land the official windows libs are MSVC ABI
Lwhile the official linux ones are GNU ABI
Mif there's an inconsistency in the headers then how has this not crashed and burned already
Lit is crashing and burning already
LLall the webgpu headers are using
_Bool, and we dont handle that properlyLno one else in their right mind uses stdbool, so its only now emerging in WebGPU
Mfrom the looks of it, all of the wgpu structs have bools in a place where it can't cause a problem in actuality
Ldid you read the issue i linked
Lits already causing problems
Mhm
L
Myeah im dumb disregard that
Lin the end, this is a bug on our side thats not worth the time and effort to fix due to the undefined ABI size of
_Bool, its better to try to fix upstream if possibleMfair
