| - Detect code paths in non-void functions that don't reach a return statement |
| |
| - Improve handling of constants and their initializers. Constant initializers |
| should never generate any code. This is trival for scalar constants. It is |
| also trivial for arrays, matrices, and vectors that are accessed with |
| constant index values. For others it is more complicated. Perhaps these |
| cases should be silently converted to uniforms? |
| |
| - Track source locations throughout the IR. There are currently several |
| places where we cannot emit line numbers for errors (and currently emit 0:0) |
| because we've "lost" the line number information. This is particularly |
| noticeable at link time. |
