Fixed the increment. Thanks for pointing it out, I was running in circles trying to fix the SetRawValue() implementation because of that. I'll remove the function in the final version of the patch.

Should I respond to all of these if I think it's been done? Should I mark the thread resolved if I think it's been done, or is that something the reviewer should do? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/979#note_11300

Sorry about the unexpected push, I'll be more careful next time. With regards to the bool fixups, are we sure we want to just write the raw data given to us? I ask because I've also noticed that SetRawValue() has a tendency to promote datatypes when given a single value and a vector / matrix paramater. I.e. float and int become a float4 and int4 respectively for both vectors and matrices. (MSDN calls this behavior a "cast.") This results in the next 3 values in the paramater's buffer being set to zero. Assuming SetRawValue() shouldn't fix the bool values itself, should it also avoid fixing the ints and floats? If so, how should we indicate the need for a fixup to other functions? There doesn't seem to be any infrastructure to support that in wine currently. (We could abuse the paramater block support for that, but see the speculation below.) The float and int promotions were the reason I didn't clear the paramater after each test. As doing so would cause us to miss the writes to the next 3 values in the paramater. As they would already be set to zero before the call. Should I still go ahead and clear the paramaters after each test anyway? As a dirty hack, I added a call to zero out the paramaters after each test with a 4x4 matrix of zero ints in v3 of the test. That call is commented out in the push, but if you enable it it will succeed for most of the tests under win10. (I disabled it before I fixed the string test crashes. So it may work fine now, I haven't checked.) I haven't tried checking the paramaters after the current one for alterations. I was going to put that in it's own set of tests. This part is speculation but, if it is a valid use of SetRawValue() to set adjacent paramaters regardless of type with one call, then the entire set of paramaters for a given effect needs to be in the same memory block. (Which seems to be not the case in wine, as there are plenty of calls to heap_alloc() / heap_realloc() using the param->data pointer in effect.c.) That would also imply that there is a specific ordering of paramaters in memory as well. Which would need to be tested for. If this behavior is combined with the bool assumption above, then we'd also need to test for order of operations too. Assuming all of that needs to be done, how do we split this up? Because I have a feeling that this patchset is going to be rather large in scope. (If all of the assumptions and speculation are true that is.) -- https://gitlab.winehq.org/wine/wine/-/merge_requests/979#note_11299
