Usage: perf-focus [options] [matcher]
Options:
--process-name <regex> filter samples by process name
--rustc-query convert from raw stacks to rustc query stacks
--print-match dump samples that match and show why they matched
--print-miss dump samples that do not match
--script-match dump samples that match in `perf script` format
--script-miss dump samples that do not match in `perf script` format
--relative make percentages relative to number of matches
--top-n <n> limit graph or histograms to the top <n> fns
--graph <file> dumps a callgraph of matching samples into <file>
--graph-callers <file> as above, but only dumps callers of the matcher
--graph-callees <file> as above, but only dumps callees of the matcher
--hist prints out the most common fns
--hist-callers prints out the most common fns amongst the callers
--hist-callees prints out the most common fns amongst the callees

see `replace_all` in Regex doc [1] for instructions.
May be specified more than once.

--from-stdin read samples from stdin;
when not using this option,
we will execute `perf script`
-F, --frequency <n> frequency at which samples were recorded (-F in perf)
(default: 1000 Hz, like perf)

-Z lower-128bit-ops=val -- rewrite operators on i128 and u128 into lang item calls (typically provided by compiler-builtins) so translation doesn't need to support them,
overriding the default for the current target
-Z human-readable-cgu-names -- generate human-readable, predictable names for codegen units
-Z dep-info-omit-d-target -- in dep-info output, omit targets for tracking dependencies of the dep-info files themselves
-Z approximate-suggestions -- include machine-applicability of suggestions in JSON output
-Z unpretty=val -- Present the input source, unstable (and less-pretty) variants;
valid types are any of the types for `--pretty`, as well as:
`flowgraph=<nodeid>` (graphviz formatted flowgraph for node),
`everybody_loops` (all function bodies replaced with `loop {}`),
`hir` (the HIR), `hir,identified`, or
`hir,typed` (HIR with types for each node).
-Z edition=val -- The edition to build Rust with. Newer editions may include features
that require breaking changes. The default edition is 2015 (the first
edition). Crates compiled with different editions can be linked together.
-Z run-dsymutil=val -- run `dsymutil` and delete intermediate object files
-Z ui-testing -- format compiler diagnostics in a way that's better suitable for UI testing
-Z embed-bitcode -- embed LLVM bitcode in object files
-Z strip-debuginfo-if-disabled=val -- tell the linker to strip debuginfo when building without debuginfo enabled.
