I think that what you observe is a change in how ES5 treats 'this' argument in builtin functions. It allows 'this' to be of any type for builtin function. The conversion to object (or using a global object in place of null) happens only when we enter JS function, if I read it right. To support this properly, I'm afraid that we'd need to pass 'this' as jsval to builtin functions. We wouldn't need any special casing for toString() then. Thanks, Jacek

Re: [PATCH v11 06/10] mshtml: Associate props with attributes for IE8 mode, but keep them stringified.

I'm not expecting that you implement all those IE8-specific things (in fact, I don't think we need to care too much about it), but the patch in its current shape can break things. Could you just remove this if() and live todo_wines? Thanks, Jacek

[PATCH v3] ws2_32: hardcode optlen to 4 for setsockopt in the TCP_NODELAY case

by Bastien Orivel

According to MSDN [1], `TCP_NODELAY` parameter should be of type `BOOL` which is 4 bytes. Due to a bug [2] in rustc passing a byte instead of an int, any program written in rust that tries to set that option on a socket will fail with a "Invalid parameter supplied" error. Turns out that setsockopt on linux does not want optlen to be less than 4 bytes [3]. Windows' behavior is the following: - For optlen <= 0, return SOCKET_ERROR and set last error to WSAEFAULT - For optlen > 0, ignore the optlen value and set the TCP_NODELAY value to one if the first byte of the given optvalue is not 0. This will fix any rust program using the hyper library to do HTTP requests.

Re: [PATCH vkd3d v8 2/4] vkd3d-shader/hlsl: Handle conditionals in copy propagation.

by Zebediah Figura

So this is failing to optimize the following program, and I can't see why: uniform int i; float main() : sv_target { float x = 0; if (0){} return x; } It generates the following code: 2: float | 0.00000000e+00 3: | = (x.x @2) 4: int | 0 5: | if (@4) { } else { } 6: float | x 7: | = (<retval-0x5620633a6280>.x @6) 8: | return 9: uint | 0 10: float | <retval-0x5620633a6280>[@9] 11: | = (<output-sv_target0>.x @10) I'd expect @6 to be rewritten to @2.x, but that doesn't happen. Do you know why?

Re: [PATCH] ntdll: Set rcx and r11 on exit from syscall dispatcher on x64.

by Paul Gofman

Thanks for testing this. First of all, I did not try to simulate every bit of volatile registers clobbering performed by the kernel. Maybe my mistake here is rather touching r11 at all (while I mostly care about rcx now) or at least making those changes in a single patch. Yet your analysis might be quite helpful, although I can't say I could follow completely. My questions are inline.

In Wine this is handled separately, the syscall_dispatcher() is not involved neither for entering the Unix part (that is done from signal) nor from continuing to user mode (that is done by setting registers from the signal handler and returning right to user mode ntdll entry point). Do you mean your test suggest some modifications to this part? That might be interesting to know but I didn't have an intention to cover all of that at once.
