Error has low context when parsing presumably invalid XML

[hegza]

Preconditions:

We have an experimental SVD generator that produces presumably incorrect CMSIS-SVD XML: file.svd.

What I did

Compiled svd2rust from master branch in debug mode, then executed:

RUST_LOG=trace ./svd2rust -i file.svd --log=trace --target=riscv

with all combinations of RUST_LOG & --log for good measure. Additionally, same results reproduce with svd2rust from cargo install svd2rust.

Output

[ERROR svd2rust] expected ,

Expected output

More context. Like, possibly a line number or more debug/trace. Discussion on Rust Embedded at Matrix yields that likely source is svd-parser itself or the error interface to it. Example output:

[TRACE svd2rust] parsing line 56
[ERROR svd2rust] expected ',' on line 56

Parsing errors now much better.
Reopen if still actual.
