# The following command will:
|
|
# 1. dump the symbols of a library using `nm`
|
|
# 2. extract only those lines that we are interested in via `grep`
|
|
# 3. from those lines, extract just the symbol name via `sed`, which:
|
|
# * always starts with "_ZN" and ends with "E" (`legacy` mangling)
|
|
# * always starts with "_R" (`v0` mangling)
|
|
# 4. sort those symbol names for deterministic comparison
|
|
# 5. write the result into a file
|
|
