[BUG] tile_arange() has issues with negative numbers

[shi-eric]

Bug Description

Example:

import warp as wp


@wp.kernel
def compute():
    a = wp.tile_arange(-10, 10, dtype=int)

    print(a)


wp.launch_tiled(compute, dim=[1], inputs=[], block_dim=16)

This code results in the following issue:

  File "/home/eshi/code-projects/warp/warp/builtins.py", line 1856, in tile_arange_value_func
    raise RuntimeError("wp.tile_arange() arguments must be compile time constants")
RuntimeError: Error while parsing function "compute" at /home/eshi/code-projects/warp/ershi-tests/test_tile_min_docstring.py:6:
    a = wp.tile_arange(-10, 10, dtype=int)
;wp.tile_arange() arguments must be compile time constants

(Note also that the RuntimeError raised in tile_arange_value_func() is not very helpful here).

Similarly, using a negative step doesn't work:

import warp as wp


@wp.kernel
def compute():
    a = wp.tile_arange(10, 0, -1, dtype=int)

    print(a)


wp.launch_tiled(compute, dim=[1], inputs=[], block_dim=16)

Output:

  File "/home/eshi/code-projects/warp/warp/builtins.py", line 1856, in tile_arange_value_func
    raise RuntimeError("wp.tile_arange() arguments must be compile time constants")
RuntimeError: Error while parsing function "compute" at /home/eshi/code-projects/warp/ershi-tests/test_tile_min_docstring.py:6:
    a = wp.tile_arange(10, 0, -1, dtype=int)
;wp.tile_arange() arguments must be compile time constants
