From 5e436b3b0ef06258ed2d7929946eb00684973183 Mon Sep 17 00:00:00 2001 From: Nick Lewycky Date: Wed, 4 May 2011 22:34:29 +0000 Subject: [PATCH] Create the parent directories to place the .gcda files in if they don't exist. That's kinda weird because the .gcno files are supposed to already be there, but libgcov does this and somehow Google has managed to depend on it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130879 91177308-0d34-0410-b5e6-96231b3b80d8 --- runtime/libprofile/GCDAProfiling.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/runtime/libprofile/GCDAProfiling.c b/runtime/libprofile/GCDAProfiling.c index 13fe0fd873d..dcf57ab9edc 100644 --- a/runtime/libprofile/GCDAProfiling.c +++ b/runtime/libprofile/GCDAProfiling.c @@ -24,6 +24,8 @@ #include #include #include +#include +#include /* #define DEBUG_GCDAPROFILING */ @@ -64,6 +66,21 @@ static char *mangle_filename(const char *orig_filename) { return filename; } +static void recursive_mkdir(const char *filename) { + char *pathname; + int i, e; + + for (i = 1, e = strlen(filename); i != e; ++i) { + if (filename[i] == '/') { + pathname = malloc(i + 1); + strncpy(pathname, filename, i); + pathname[i] = '\0'; + mkdir(pathname, 0750); /* some of these will fail, ignore it. */ + free(pathname); + } + } +} + /* * --- LLVM line counter API --- */ @@ -75,6 +92,7 @@ static char *mangle_filename(const char *orig_filename) { void llvm_gcda_start_file(const char *orig_filename) { char *filename; filename = mangle_filename(orig_filename); + recursive_mkdir(filename); output_file = fopen(filename, "wb"); /* gcda file, version 404*, stamp LLVM. */
