Oh, hes bool variant is the wrong one. But __sync_val_compare_and_swap should work fine. _Interloc…
Oops! I just realized that my implementation of AtomicCompareExchangeUInt32 is bogus. I shouldn't …
Thank you for the answers. Casey are you willing to implement CompletePreviousWritesBeforeFutureWr…
Just a quick note: you do not want sfence for write barriers on x64. x64's always complete writes…
Pseudonym73, are you sure? Wouldn't we see a lot of crashing software on AMD 64-bit CPU's if they …
In the first case, you want a store fence: In most Intel CPUs, writes are not reordered with othe…
It doesn't matter what version is Visual Studio. Afaik it is available only as 32-bit. If you use …

I think this is the issue...I'm looking into it. I'm not sure if I somehow ended up with a 32bit v…
Are you compiling executable as 64-bit? If you compile executable as 32-bit, then even on 64-bit O…

Hey all, I recently got started watching the Handmade Hero series. I've followed up to the point w…
I'm don't think there is better way for GCC to do just write barrier. Clang should support both of…
In order to get HH compiling again I would like to have CompletePreviousWritesBeforeFutureWrites a…
Yes, just to be clear, it's because it is in a struct with a pointer that I said it would be padde…

Casey is writing code assuming that on Windows it will be compiled with MSVC. Compiling with gcc w…
Oh for Swift. Afaik Swift doesn't support simd/neon intrinsic stuff. It needs to be in compiler/la…

I meant SIMD support in Swift specifically. I already implemented the functions in C before, but w…

I was wondering if anyone knew how to compile with g++. The visual studio compiler doesn't work fo…
That is not a reasonable assumption. Some time I had need to compile code where compiler assumed e…
OSX has proper SSE intrinsic support. What you meant probably is that iOS doesn't support SSE. iOS…
I am not too concerned about it since the code obviously runs fine. I was simply wondering if it i…

Ok, thank you. I'll investigate further. If I find the cause, I'll post it here. Small off topic q…
Actually this is a pretty good point, because it clears up a distinction we were having that we sh…
Yeah, enums kind of suck in C. You really want them to be typed, but I think that wasn't introduc…
