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

# "cd" and globbing are unsupported in lit internal runner.

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

llvm-cov: Print coverage summary to STDOUT. File summaries will now be optionally outputted which will give line, branching and call coverage info. Unfortunately, clang's current instrumentation does not give enough information to deduce function calls, something that gcc is able to do. Thus, no calls are always outputted to be consistent with gcov output. Also updated tests. llvm-svn: 197606

RUN: llvm-cov -gcno=test.gcno -gcda=test.gcda | diff test_no_options.output -
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

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

RUN: llvm-cov -gcno=test.gcno -gcda=test.gcda -a -b | diff test_-b.output -
llvm-cov: Added -b option for branch probabilities. This option tells llvm-cov to print out branch probabilities when a basic block contains multiple branches. It also prints out some function summary info including the number of times the function enters, the percent of time it returns, and how many blocks were executed. Also updated tests. llvm-svn: 197198

RUN: diff -aub test_-a_-b.cpp.gcov test.cpp.gcov
RUN: diff -aub test_-a_-b.h.gcov test.h.gcov
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. llvm-svn: 197432

RUN: diff -aub test_-a_-b_-u.cpp.gcov test.cpp.gcov
RUN: diff -aub test_-a_-b_-u.h.gcov test.h.gcov
llvm-cov: Added -c option for branch counts. This will cause llvm-cov to output branch counts instead of branch probabilities. -b must be enabled. Also updated tests. llvm-svn: 197594

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

Un-revert r196358: "llvm-cov: Added support for function checksums." And add the proper fix. llvm-svn: 196367

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

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
