From cbf5311a347da4745e92fcd0e15997f5d4960ab9 Mon Sep 17 00:00:00 2001 From: Justin Bogner Date: Wed, 3 Jun 2015 02:48:09 +0000 Subject: [PATCH] llvm-cov: Make llvm-cov --version DTRT In r233132 we started requiring a subcommand in llvm-cov, but this made `llvm-cov --version` invalid, which is kind of silly. Print version information in this case, as most people would expect. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@238897 91177308-0d34-0410-b5e6-96231b3b80d8 --- tools/llvm-cov/llvm-cov.cpp | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/tools/llvm-cov/llvm-cov.cpp b/tools/llvm-cov/llvm-cov.cpp index bf66f583a52..8c5acaef63b 100644 --- a/tools/llvm-cov/llvm-cov.cpp +++ b/tools/llvm-cov/llvm-cov.cpp @@ -13,6 +13,7 @@ #include "llvm/ADT/StringRef.h" #include "llvm/ADT/StringSwitch.h" +#include "llvm/Support/CommandLine.h" #include "llvm/Support/Path.h" #include "llvm/Support/Process.h" #include "llvm/Support/raw_ostream.h" @@ -43,6 +44,12 @@ static int helpMain(int argc, const char *argv[]) { return 0; } +/// \brief Top level version information. +static int versionMain(int argc, const char *argv[]) { + cl::PrintVersionMessage(); + return 0; +} + int main(int argc, const char **argv) { // If argv[0] is or ends with 'gcov', always be gcov compatible if (sys::path::stem(argv[0]).endswith_lower("gcov")) @@ -57,6 +64,7 @@ int main(int argc, const char **argv) { .Case("report", reportMain) .Case("show", showMain) .Cases("-h", "-help", "--help", helpMain) + .Cases("-version", "--version", versionMain) .Default(nullptr); if (Func) {
