Further fix to llvm-cov test. It turns out that in some build systems, tests are executed in a non-writable directory. Hopefully, this finally fixes the issue. llvm-svn: 196256 2013-12-03 08:21:14 +00:00			`# "cd" and globbing are unsupported in lit internal runner.`
Fix llvm-cov test as suggested in r196228's post commit review. llvm-svn: 196255 2013-12-03 07:56:23 +00:00			`REQUIRES: shell`

llvm-cov: Another fix to llvm-cov test. Copy all test files to temporary directory, not just test.* files. Tests didn't fail because the missing files occurred in XFAILS. llvm-svn: 196305 2013-12-03 19:05:03 +00:00			`RUN: cp %p/Inputs/test* .`

llvm-cov: Removed output to STDOUT/specified file. Instead of asking the user to specify a single file to output coverage info and defaulting to STDOUT, llvm-cov now creates files for each source file with a naming system of: <source filename> + ".llcov". This is what gcov does and although it can clutter the working directory with numerous coverage files, it will be easier to hook the llvm-cov output to tools which operate on this assumption (such as lcov). llvm-svn: 196184 2013-12-03 00:57:11 +00:00			`RUN: llvm-cov -gcno=test.gcno -gcda=test.gcda`
llvm-cov: Added -a option for block data. Similar to gcov, llvm-cov will now print out the block count at the end of each block. Multiple blocks can end on the same line. One computational difference is by using -a, llvm-cov will no longer simply add the block counts together to form a line count. Instead, it will take the maximum of the block counts on that line. This has a similar effect to what gcov does, but generates more correct counts in certain scenarios. Also updated tests. llvm-svn: 196856 2013-12-10 01:02:07 +00:00			`RUN: diff -aub test_no_options.cpp.gcov test.cpp.gcov`

Added basic unit test for llvm-cov. This test compares the output of llvm-cov against a coverage file generated by gcov. Currently, llvm-cov does not work on certain platforms (namely big-endian architectures such as PowerPC, among others). These platforms are marked as XFAIL for now, but will be fixed later. llvm-svn: 194616 2013-11-13 22:50:15 +00:00
llvm-cov: Replaced asserts with proper error handling. Unified the interface for read functions. They all return a boolean indicating if the read from file succeeded. Functions that previously returned the read value now store it into a variable that is passed in by reference instead. Callers will need to check the return value to detect if an error occurred. Also added a new test which ensures that no assertions occur when file contains invalid data. llvm-cov should return with error code 1 upon failure. llvm-svn: 194635 2013-11-14 00:07:15 +00:00			`RUN: not llvm-cov -gcno=test_read_fail.gcno -gcda=test.gcda`

Un-revert r196358: "llvm-cov: Added support for function checksums." And add the proper fix. llvm-svn: 196367 2013-12-04 08:57:17 +00:00			`RUN: not llvm-cov -gcno=test.gcno -gcda=test_file_checksum_fail.gcda`

			`RUN: not llvm-cov -gcno=test.gcno -gcda=test_func_checksum_fail.gcda`
llvm-cov: Added file checksum to gcno and gcda files. Instead of permanently outputting "MVLL" as the file checksum, clang will create gcno and gcda checksums by hashing the destination block numbers of every arc. This allows for llvm-cov to check if the two gcov files are synchronized. Regenerated the test files so they contain the checksum. Also added negative test to ensure error when the checksums don't match. llvm-svn: 195191 2013-11-20 04:15:05 +00:00
mips: XFAIL llvm-cov test XFAIL llvm-cov.test for MIPS until big-endian issues are fixed for llvm-cov. The test does pass on MIPS little-endian. llvm-svn: 195966 2013-11-29 21:59:09 +00:00			`XFAIL: powerpc64, s390x, mips`
