From 38b9b568b950d2c200e1de2e9cb87d5f8ff6d59f Mon Sep 17 00:00:00 2001 From: Nick Lewycky Date: Fri, 29 Jul 2011 04:42:39 +0000 Subject: [PATCH] Teach Path::GetCurrentDirectory to use $PWD, to support users who like to do screwy things by setting PWD != getcwd(). For example, some developers I know will use this to control the value in gcc's DW_AT_comp_dir value in debug output. With this patch, that trick will now work on clang too. The only other effect of this change is that the static analysis will now respect $PWD when reporting the directory of the files in its HTML output. I think that's fine. llvm-svn: 136459 --- llvm/lib/Support/Unix/Path.inc | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/llvm/lib/Support/Unix/Path.inc b/llvm/lib/Support/Unix/Path.inc index f295b92e4a5b..a139399cba3b 100644 --- a/llvm/lib/Support/Unix/Path.inc +++ b/llvm/lib/Support/Unix/Path.inc @@ -251,9 +251,12 @@ Path::GetUserHomeDirectory() { Path Path::GetCurrentDirectory() { + if (char *pwd = getenv("PWD")) + return Path(pwd); + char pathname[MAXPATHLEN]; - if (!getcwd(pathname,MAXPATHLEN)) { - assert (false && "Could not query current working directory."); + if (!getcwd(pathname, MAXPATHLEN)) { + assert(false && "Could not query current working directory."); return Path(); }
