Sorry about all the crashes, there were several failed cut-and-pastes from the prototype script. Everything appears to be working now. (...?) 😰 |
This patch fixes errors in the parser of perf output. Previously, each record was assumed to be separated by spaces, but this failed for more generic records (usually from C++) which included signatures (such as `f(a, b)`) or templates (`f<a, b>`). Nested constructs were also possible. This is fixed by introducing a simple tokenizer which extracts <, (, and whitespace from the output , then rebuilds the records by combining any whitespace which appears inside of delimiters. This patch should hopefully resolve the CI errors in GitHub Actions.
