From c4ede8f8af27e328c9d4dcbe5f8c9a07b4653d4b Mon Sep 17 00:00:00 2001 From: Michal Gorny Date: Wed, 8 Aug 2018 20:45:03 +0000 Subject: [PATCH] [cmake] Append LLVM_VERSION_SUFFIX to SOVERSION Append LLVM_VERSION_SUFFIX to SOVERSION. This makes it possible to use the suffix to differentiate binary-incompatible versions of LLVM built via BUILD_SHARED_LIBS. We are planning to use this to temporarily preserve ABI-incompatible variants of LLVM while switching the system between them, e.g. when rebuilding the system to use libc++. Normally this would mean that once LLVM is rebuilt using libc++ all the reverse dependencies become immediately broken. Using a distinct SOVERSION allows us to preserve the ABI compatibility before all the packages are rebuilt.
