* llvm-readobj: address review comments for ARM EHABI printingSaleem Abdulrasool2014-01-09
| | | | | | | | Rename bytecode to opcodes to make it more clear. Change an impossible case to llvm_unreachable instead. Avoid allocation of a buffer by modifying the PrintOpcodes iteration. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198848 91177308-0d34-0410-b5e6-96231b3b80d8
* tests: disable ARM unwinding tests if ARM is unavailableSaleem Abdulrasool2014-01-08
| | | | | | | | | | Appease the buildbots for targets which do not build the ARM support by moving the ARM specific test into a subdirectory and use the lit configuration to disable them appropriately. Thanks to chapuni and thakis for explaining how to do this! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198736 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-readobj: add support for ARM EHABI unwind infoSaleem Abdulrasool2014-01-08
| | | | | | | | | | | | | | | This adds some preliminary support for decoding ARM EHABI unwinding information. The major functionality that remains from complete support is bytecode translation. Each Unwind Index Table is printed out as a separate entity along with its section index, name, offset, and entries. Each entry lists the function address, and if possible, the name, of the function to which it corresponds. The encoding model, personality routine or index, and byte code is also listed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198734 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-cov: Added -f option for function summaries.Yuchen Wu2013-12-19
| | | | | | | | | | | Similar to the file summaries, the function summaries output line, branching and call statistics. The file summaries have been moved outside the initial loop so that all of the function summaries can be outputted before file summaries. Also updated test cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197633 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Print coverage summary to STDOUT.Yuchen Wu2013-12-18
| | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197606 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Added -c option for branch counts.Yuchen Wu2013-12-18
| | | | | | | | | This will cause llvm-cov to output branch counts instead of branch probabilities. -b must be enabled. Also updated tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197594 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-cov: Added -u option for unconditional branch info.Yuchen Wu2013-12-16
| | | | | | | | | 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
* llvm-cov: Added -b option for branch probabilities.Yuchen Wu2013-12-13
| | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197198 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Added -a option for block data.Yuchen Wu2013-12-10
| | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196856 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-cov: Another fix to llvm-cov test.Yuchen Wu2013-12-03
| | | | | | | Copy all test files to temporary directory, not just test.* files. Tests didn't fail because the missing files occurred in XFAILS. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196305 91177308-0d34-0410-b5e6-96231b3b80d8
* Further fix to llvm-cov test.Daniel Jasper2013-12-03
| | | | | | | It turns out that in some build systems, tests are executed in a non-writable directory. Hopefully, this finally fixes the issue. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196256 91177308-0d34-0410-b5e6-96231b3b80d8

* Copy input files to test directory.Daniel Jasper2013-12-03
| | | | | | | | | | | 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". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196228 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-cov: Removed output to STDOUT/specified file.Yuchen Wu2013-12-03
| | | | | | | | | | | | 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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196184 91177308-0d34-0410-b5e6-96231b3b80d8
* mips: XFAIL llvm-cov testPetar Jovanovic2013-11-29
| | | | | | | | XFAIL llvm-cov.test for MIPS until big-endian issues are fixed for llvm-cov. The test does pass on MIPS little-endian. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195966 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Added file checksum to gcno and gcda files.Yuchen Wu2013-11-20
| | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195191 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-cov: Removed StringMap holding GCOVLines.Yuchen Wu2013-11-14
| | | | | | | | | | | | | | | | | According to the hazy gcov documentation, it appeared to be technically possible for lines within a block to belong to different source files. However, upon further investigation, gcov does not actually support multiple source files for a single block. This change removes a level of separation between blocks and lines by replacing the StringMap of GCOVLines with a SmallVector of ints representing line numbers. This also means that the GCOVLines class is no longer needed. This paves the way for supporting the "-a" option, which will output block information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194637 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Replaced asserts with proper error handling.Yuchen Wu2013-11-14
| | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194635 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | This test compares the output of llvm-cov against a coverage file generated by gcov.

These platforms are marked as XFAIL for now, but will be fixed later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194616 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | This reverts commit r194451. Not sure why the tests are failing on the buildbot. They run fine on my local machine. Could it possibly be because of the endianness of the architectures? The GCNO and GCDA files are little-endian encoded, and llvm-cov expects it to remain that way. Is this a safe assumption? git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194454 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-objdump: Dump COFF import table if -private-headers option is given.Rui Ueyama2013-09-27
| | | | | | | | | | | | | | | | This is a patch to add capability to llvm-objdump to dump COFF Import Table entries, so that we can write tests for LLD checking Import Table contents. llvm-objdump did not print anything but just file name if the format is COFF and -private-headers option is given. This is a patch adds capability for dumping DLL Import Table, which is specific to the COFF format. In this patch I defined a new iterator to iterate over import table entries. Also added a few functions to COFFObjectFile.cpp to access fields of the entry.
