[PATCH] D84610: [ELF] --icf: don't fold text sections with LSDA

[Amos Bird via Phabricator via llvm-commits]

amosbird added a comment.

I've compared three version of lld by linking clickhouse with `-fexceptions` and `--icf=all`. Here are the stripped binary size of the related outputs:

| bytes | binary     |                          |
| 259837744     | clickhouse | <---- clang12 (patch)    |
| 249643904     | clickhouse | <---- clang12 (no-patch) |
| 249643824     | clickhouse | <---- clang10            |
