[llvm-cxxfilt]Add test to show that empty lines can be handled I recently discovered a bug in llvm-cxxfilt introduced in r353743 but was fixed later incidentally due to r355031. Specifically, llvm-cxxfilt was attempting to call .back() on an empty string any time there was a new line in the input. This was causing a crash in my debug builds only. This patch simply adds a test that explicitly tests that llvm-cxxfilt handles empty lines correctly. It may pass under release builds under the broken behaviour, but it fails at least in debug builds.

[llvm-cxxfilt] Improve strip-underscore behavior Summary: For platform that uses macho format, c++filt should be stripping the leading underscore by default. Introduce the binutil compatible "-n" option to control strip-undercore behaivor together with the existing "-_" option and fallback to system default if none of them are set. rdar://problem/57173514 Reviewers: compnerd, erik.pilkington, dexonsmith, mattd Reviewed By: compnerd, erik.pilkington Subscribers: jkorous, ributzka, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D70250 2019-11-18 23:51:41 +01:00			`RUN: llvm-cxxfilt -n < %t \| FileCheck %s`
