From 89452cf827d9699027b60212b2795b9e14d5ea7a Mon Sep 17 00:00:00 2001 From: Yuchen Wu Date: Mon, 16 Dec 2013 22:14:02 +0000 Subject: llvm-cov: Added -u option for unconditional branch info. Outputs branch information for unconditional branches in addition to conditional branches. -b option must be enabled. Also updated tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197432 91177308-0d34-0410-b5e6-96231b3b80d8 --- test/tools/llvm-cov/Inputs/test_-a_-b_-u.cpp.gcov | 160 ++++++++++++++++++++++ test/tools/llvm-cov/Inputs/test_-a_-b_-u.h.gcov | 14 ++ 2 files changed, 174 insertions(+) create mode 100644 test/tools/llvm-cov/Inputs/test_-a_-b_-u.cpp.gcov create mode 100644 test/tools/llvm-cov/Inputs/test_-a_-b_-u.h.gcov (limited to 'test/tools/llvm-cov/Inputs') diff --git a/test/tools/llvm-cov/Inputs/test_-a_-b_-u.cpp.gcov b/test/tools/llvm-cov/Inputs/test_-a_-b_-u.cpp.gcov new file mode 100644 index 0000000000..0d2c6b3935 --- /dev/null +++ b/test/tools/llvm-cov/Inputs/test_-a_-b_-u.cpp.gcov @@ -0,0 +1,160 @@ + -: 0:Source:test.cpp + -: 0:Graph:test.gcno + -: 0:Data:test.gcda + -: 0:Runs:2 + -: 0:Programs:1 + -: 1:#include "test.h" + -: 2:#include + -: 3: + -: 4:bool on = false;
