From 66e30f8db180bdc0fba637c84e7b72396a08d8f2 Mon Sep 17 00:00:00 2001 From: Bill Wendling Date: Tue, 27 Mar 2012 21:17:04 +0000 Subject: Try to use the CWD if the path to the GCDA output is not available (e.g., the executable has been moved to another machine). If that's not available (read-only or something), then exit gracefully. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@153538 91177308-0d34-0410-b5e6-96231b3b80d8 --- runtime/libprofile/GCDAProfiling.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/runtime/libprofile/GCDAProfiling.c b/runtime/libprofile/GCDAProfiling.c index 4ffb12b15e..712dba08be 100644 --- a/runtime/libprofile/GCDAProfiling.c +++ b/runtime/libprofile/GCDAProfiling.c @@ -113,6 +113,20 @@ void llvm_gcda_start_file(const char *orig_filename) { recursive_mkdir(filename); output_file = fopen(filename, "wb"); + if (!output_file) { + filename[0] = '\0'; /* The size of filename should be big enough. */ + char *cptr = strrchr(orig_filename, '/'); + strcat(filename, cptr ? cptr + 1 : orig_filename); + output_file = fopen(filename, "wb"); + + if (!output_file) { + fprintf(stderr, "LLVM profiling runtime: while opening '%s': ", + filename); + perror(""); + exit(1); + } + } + /* gcda file, version 404*, stamp LLVM. */ #ifdef __APPLE__ fwrite("adcg*204MVLL", 12, 1, output_file); -- cgit v1.2.3
