Add new compatibility mode to binary, to be able to replace llvm-symbolizer/addr2line #314

Closed qarmin closed 3 months ago

I have found crash with AddressSanitizer in zed and used commands from below to get readable output 

export ASAN_SYMBOLIZER_PATH=$(which llvm-symbolized-18)
export ASAN_OPTIONS=symbolize=1

this worked fast, but I got not fully converted output

with

export ASAN_SYMBOLIZER_PATH=$(which addr2line)
export ASAN_OPTIONS=symbolize=1

I got proper

but entire operation took almost 160 seconds (llvm-symbolizer took 2 seconds)

When compiling this package and trying to use it, I have this error

export ASAN_SYMBOLIZER_PATH=$(which a2l)
zed
==177959==ERROR: External symbolizer path is set to '/home/rafal/.cargo/bin/a2l' which isn't a known symbolizer. Please set the path to the llvm-symbolizer binary or other known tool.

it is possible to add new mode to be able to replace llvm-symbolizer?

Nevermind, looks that sanitizer checks for specific name
