symbolizer [<options>]
Parses log from stdin and converts symbolizer markups into human readable
stack traces using local or remote debug symbols.
选项：
--analytics-show
Show the opt-in/out status for collection of analytics and what we collect when opt-in.
--analytics=enable|disable
Enable or disable collection of analytics:
--analytics=enable Enable collection of analytics and save the
status in a configuration file.
--analytics=disable Disable collection of analytics and save the
status in a configuration file.
--auth \[deprecated]
Starts the authentication process for symbol servers.
--build-id-dir=<path>
Adds the given directory to the symbol search path. Multiple
--build-id-dir switches can be passed to add multiple directories.
The directory must have the same structure as a .build-id directory,
that is, each symbol file lives at xx/yyyyyyyy.debug where xx is
the first two characters of the build ID and yyyyyyyy is the rest.
However, the name of the directory doesn't need to be .build-id.
--dumpfile-output=<path>
Write the dumpfile output to the given file.
--help
-h
Prints this help.
--ids-txt=<path>
Adds the given file to the symbol search path. Multiple --ids-txt
switches can be passed to add multiple files. The file, typically named
"ids.txt", serves as a mapping from build ID to symbol file path and
should contain multiple lines in the format of "<build ID> <file path>".
--omit-module-lines
Omit the "\[\[\[ELF module ...]]]" lines from the output.
--prettify-backtrace
Try to prettify backtraces.
--symbol-cache=<path>
Directory where we can keep a symbol cache, which defaults to
~/.fuchsia/debug/symbol-cache. If a symbol server has been specified,
downloaded symbols will be stored in this directory. The directory
structure will be the same as a .build-id directory, and symbols will
be read from this location as though you had specified
"--build-id-dir=<path>".
--symbol-index=<path>
Populates --ids-txt and --build-id-dir using the given symbol-index file,
which defaults to ~/.fuchsia/debug/symbol-index. The file should be
created and maintained by the "symbol-index" host tool.
--symbol-path=<path>
-s <path>
Adds the given directory or file to the symbol search path. Multiple
-s switches can be passed to add multiple locations. When a directory
path is passed, the directory will be enumerated non-recursively to
index all ELF files. When a file is passed, it will be loaded as an ELF
file (if possible).
--symbol-server=<url>
Adds the given URL to symbol servers. Symbol servers host the debug
symbols for prebuilt binaries and dynamic libraries.
--version
-v
Prints the version.
