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: cd %p/Inputs`

llvm-cov.test: Tweak win32 hosts not confused by \r\n in llvm-cov's stdout. "diff -b" -- Ignore space changes. llvm-svn: 194694 2013-11-14 11:45:10 +00:00			`RUN: \| diff -aub 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: 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`

llvm-cov.test: Remove XFAIL:arm. Seems this is passing since my tweaks. llvm-svn: 194712 2013-11-14 17:08:26 +00:00			`XFAIL: powerpc64, s390x`
