shingjan opened a new pull request #9306:
URL: https://github.com/apache/tvm/pull/9306
This PR intends to improve the error rendering by annotating regions of
interest in TIR like synr following PR #8121.
Previously when there is an error:
```
The IR is:
@tvm.script.ir_module
class Module:
@tir.prim_func
def main(a: tir.handle, b: tir.handle) -> None:
A = tir.match_buffer(a, [128, 128, 128, 128], dtype="float32")
B = tir.match_buffer(b, [128, 128, 128, 128], dtype="float32")
# body
# with tir.block("root")
for i, j, k, l in tir.grid(128, 128, 128, 8):
with tir.block([128, 128, 128, 128], "B") as [vi, vj, vk, vl]:
tir.bind(vi, i)
tir.bind(vj, j)
tir.bind(vk, k)
tir.bind(vl, l * 16)
tir.reads([A[vi, vj, vk, vl]])
tir.writes([B[vi, vj, vk, vl]])
B[vi, vj, vk, vl] = A[vi, vj, vk, vl] * tir.float32(2)
Regions of interest:
tir.Block#0
block B(iter_var(vi, range(min=0, ext=128)), iter_var(vj, range(min=0,
ext=128)), iter_var(vk, range(min=0, ext=128)), iter_var(vl, range(min=0,
ext=128))) {
reads([A[vi, vj, vk, vl]])
writes([B[vi, vj, vk, vl]])
B[vi, vj, vk, vl] = (A[vi, vj, vk, vl]*2f)
}
```
With this PR, the error will be rendered like below:
```
The IR with diagnostic is:
@tvm.script.ir_module
class Module:
@tir.prim_func
def main(a: tir.handle, b: tir.handle) -> None:
A = tir.match_buffer(a, [128, 128, 128, 128], dtype="float32")
B = tir.match_buffer(b, [128, 128, 128, 128], dtype="float32")
# body
# with tir.block("root")
for i, j, k, l in tir.grid(128, 128, 128, 8):
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
with tir.block([128, 128, 128, 128], "B") as [vi, vj, vk, vl]:
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
tir.bind(vi, i)
tir.bind(vj, j)
tir.bind(vk, k)
tir.bind(vl, l * 16)
tir.reads([A[vi, vj, vk, vl]])
tir.writes([B[vi, vj, vk, vl]])
B[vi, vj, vk, vl] = A[vi, vj, vk, vl] * tir.float32(2)
```
