Hello, I find a problem about usage. The commit 1910070b298052d7ca8e4024891465824588c1e9 fixed demangle.h to remove support for ancient GNU (pre-3.0), Lucid, ARM, HP, and EDG demangling styles. But usage of nm and objdump is still show the following message. -C, --demangle[=STYLE] Decode low-level symbol names into user-level names The STYLE, if specified, can be `auto' (the default), `gnu', `lucid', `arm', `hp', `edg', `gnu-v3', `java' or `gnat' So if you execute --demangle=gnu, it will display error message: unknown demangling style gnu. Would you delete unsupported styles from usage of nm and objdump?
