From ec44cfdaf0a14fc542b611b223f9be464c688ce5 Mon Sep 17 00:00:00 2001 From: Rafael Espindola Date: Tue, 6 Sep 2016 19:16:48 +0000 Subject: Add an c++ itanium demangler to llvm. This adds a copy of the demangler in libcxxabi. The code also has no dependencies on anything else in LLVM. To enforce that I added it as another library. That way a BUILD_SHARED_LIBS will fail if anyone adds an use of StringRef for example. The no llvm dependency combined with the fact that this has to build on linux, OS X and Windows required a few changes to the code. In particular: No constexpr. No alignas On OS X at least this library has only one global symbol: __ZN4llvm16itanium_demangleEPKcPcPmPi My current plan is: Commit something like this Change lld to use it Change lldb to use it as the fallback Add a few #ifdefs so that exactly the same file can be used in libcxxabi to export abi::__cxa_demangle. Once the fast demangler in lldb can handle any names this implementation can be replaced with it and we will have the one true demangler. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@280732 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/Demangle/lit.local.cfg | 1 + test/Demangle/simple.test | 4 ++++ 2 files changed, 5 insertions(+) create mode 100644 test/Demangle/lit.local.cfg create mode 100644 test/Demangle/simple.test (limited to 'test/Demangle') diff --git a/test/Demangle/lit.local.cfg b/test/Demangle/lit.local.cfg new file mode 100644 index 00000000000..df9b335dd13 --- /dev/null +++ b/test/Demangle/lit.local.cfg @@ -0,0 +1 @@ +config.suffixes = ['.test'] diff --git a/test/Demangle/simple.test b/test/Demangle/simple.test new file mode 100644 index 00000000000..76e70dbba30 --- /dev/null +++ b/test/Demangle/simple.test @@ -0,0 +1,4 @@ +RUN: llvm-cxxfilt _Z1fi abc | FileCheck %s + +CHECK: f(int) +CHECK-NEXT: abc -- cgit v1.2.3
