Copy input files to test directory. With r196184, llvm-cov creates a new file right next to the input file. However, the Inputs-directory can't simply be assumed to be writable under all build systems. Also, this prevents a new source file from showing up in the source tree if the test aborts before the call to "rm". llvm-svn: 196228 2013-12-03 07:35:32 +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`

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`

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			`RUN: not llvm-cov -gcno=test.gcno -gcda=test_checksum_mismatch.gcda`

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`
