[QST] Does numba-cuda emit coverage for `coverage.py`?

[qalshidi]

Hi,

I ran the following with environment variables NUMBA_JIT_COVERAGE=1 and NUMBA_COVERAGE=1.

import numpy as np
from numba import cuda
import numba as nb

@nb.jit
def fn_w_branch(x):
    x[1] = 1
    x[2] = x[0] + x[1]
    if x[0] == 0:
        x[0] = 5
    else:
        x[0] = 7

@cuda.jit
def fn_1(x):
    x[0] = 5

@cuda.jit
def fn(x):
    x[0] = dev_fn(5)

@cuda.jit(device=True)
def dev_fn(x):
    if x == 5:
        return x + 5
    else:
        return x + 7

items = np.zeros(12)

fn_1[1,1](items)
print(items)

fn[1,1](items)
print(items)

fn_w_branch(items)
print(items)

The output I get after coverage run file.py coverage report -m is as follows:

Name            Stmts   Miss  Cover   Missing
---------------------------------------------
reproducer.py      28      5    82%   16, 20, 24-27
---------------------------------------------
TOTAL              28      5    82%

It seems the regular numba jit compiled code was measured but not the cuda jit code. Is there a way to make cuda jit compiled code emit coverage data?

Thanks.
