| # This is wrapper for faster addr2line, that is required for "perf --call-graph dwarf" | |
| # NOTE: since v6.3 perf supports specifying addr2line and supports LLVM so it is not required there | |
| # stdbuf is important here to avoid buffering, otherwise perf will stuck | |
| stdbuf -o0 -i0 sed -e 's/,//' -e 's/^$/ffffffffffffff/' | llvm-addr2line "$@" |
