00:40 <jenneron[m]> does mesa have problems with LPAE? when I use java with 2048 ram allocated it works, but not enough for my case, when i set max as e.g. 2600, i get a cannot allocate memory error from exyns_dri.so

13:06 <q4a> I'm a bit confused in `mux.i32`. Valhall docs says: If true, `A` is chosen, else `B` is chosen. The `bit` modifier acts bitwise, equivalent to `bitselect()` in OpenCL, so `MUX.i32.bit A, B, mask` calculates `(A & mask) | (A & ~mask)`.

13:07 <q4a> `bitselect()` in OpenCL says: Each bit of result is corresponding bit of a if corresponding bit of c is 0. Otherwise it is the corresponding bit of b.

13:07 <q4a> So this is: `(A & ~mask) | (B & mask)`YR

13:09 <q4a> alyssa: correct `mux.i32` calculation is `(A & ~mask) | (B & mask)` or `(A & mask) | (B & ~mask)`
