Kazu Hirata	b6a01caa64	[llvm/unittests] Use std::nullopt instead of None (NFC) ... This patch mechanically replaces None with std::nullopt where the compiler would warn if None were deprecated. The intent is to reduce the amount of manual work required in migrating from Optional to std::optional. This is part of an effort to migrate from llvm::Optional to std::optional: https://discourse.llvm.org/t/deprecating-llvm-optional-x-hasvalue-getvalue-getvalueor/63716	2022-12-02 22:10:37 -08:00
Daniel Thornburgh	8bd078b57c	[Symbolize] Parse multi-line markup elements. ... This allows registering certain tags as possibly beginning multi-line elements in the symbolizer markup parser. The parser is kept agnostic to how lines are delimited; it reports the entire contents, including line endings, once the end of element marker is reached.

Daniel Thornburgh	2040b6df0a	[Symbolize] Parser for log symbolizer markup. ... This adds a parser for the log symbolizer markup format discussed in https://discourse.llvm.org/t/rfc-log-symbolizer/61282. The parser operates in a line-by-line fashion with minimal memory requirements. This doesn't yet include support for multi-line tags or specific parsing for ANSI X3.64 SGR control sequences, but it can be extended to do so. The latter can also be relatively easily handled by examining the resulting text elements. Reviewed By: peter.smith Differential Revision: https://reviews.llvm.org/D124686	2022-06-17 10:26:24 -07:00
