Adrian Prantl 212c104ea3 Reapply "Avoid emitting redundant or unusable directories in DIFile metadata entries."" ... This reverts commit r348280 and reapplies D55085 without modifications. Original commit message: Avoid emitting redundant or unusable directories in DIFile metadata entries. As discussed on llvm-dev recently, Clang currently emits redundant directories in DIFile entries, such as .file 1 "/Volumes/Data/llvm" "/Volumes/Data/llvm/tools/clang/test/CodeGen/debug-info-abspath.c" This patch looks at any common prefix between the compilation directory and the (absolute) file path and strips the redundant part. More importantly it leaves the compilation directory empty if the two paths have no common prefix. After this patch the above entry is (assuming a compilation dir of "/Volumes/Data/llvm/_build"): .file 1 "/Volumes/Data/llvm" "tools/clang/test/CodeGen/debug-info-abspath.c" When building the FileCheck binary with debug info, this patch makes the build artifacts ~1kb smaller. Differential Revision: https://reviews.llvm.org/D55085 llvm-svn: 348513		2018-12-06 18:44:50 +00:00
