Use and() and or() functions for logical-AND and OR (#6310)

2025-02-08T02:27:23+00:00

* Use and() and or() functions for logical-AND and OR With this commit, Slang will emit function calls to `and()` and `or()` for the logical-AND and logical-OR when the operands are non-scalar and the target profile is SM6.0 and above. This is required change from SM6.0. For WGSL, there is no operator overloadings of `&&` and `||` when the operands are non-scalar. Unlike HLSL, WGSL also don't have `and()` nor `or()`. Alternatively, we can use `select()`.

WGSL: Convert signed vector shift amounts to unsigned (#6023)

2025-01-10T19:05:05+00:00

* WGSL: Fixes for signed shift amounts - Handle the case of vector shift amounts - Closes #5985 - Move handling of scalar case from emit to legalization - Add tests for bitshifts. * Move the binary operator legalization function to a common place * Metal: Legalize binary operations Closes #6029. * Fix Metal filecheck test The int shift amounts are now converted to unsigned. * format code --------- Co-authored-by: slangbot <186143334+slangbot@users.noreply.github.com> Co-authored-by: Yong He
