* Do not XFAIL test/tools/llvm-cov tests on powerpc64leUlrich Weigand2014-06-18
| | | | | | | | | | | | | All tests in test/tools/llvm-cov fail on big-endian targets and are supposed to be XFAILed there. However, including "powerpc64" in the XFAIL line is now incorrect, since that matches both powerpc64- and powerpc64le- targets, and the tests pass on the latter. Update the XFAIL lines to use powerpc64- instead (like mips64-). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211172 91177308-0d34-0410-b5e6-96231b3b80d8

* ProfileData: Allow multiple profiles in RawInstrProfReaderJustin Bogner2014-05-16
| | | | | | | | | | | | | | | | | | | Allow multiple raw profiles to coexist in a single .profraw file, given the following conditions: - Zero padding at the end of or between profiles will be skipped. - Each profile must start with a valid header. - Mixing endianness or pointer sizes in concatenated profiles files is not allowed. This is needed to handle cases where a program's shared libraries are profiled as well as the main executable itself, as we'll need to emit each executable's counters. Combining the tables in the runtime would be expensive for the instrumented program. rdar://16918688 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208938 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-cov: Handle missing source files as GCOV doesJustin Bogner2014-05-07
| | | | | | | | | | | If the source files referenced by a gcno file are missing, gcov outputs a coverage file where every line is simply /*EOF*/. This also occurs for lines in the coverage that are past the end of a file that is found. This change mimics gcov. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208149 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Implement --no-outputJustin Bogner2014-05-07
| | | | | | | | In gcov, there's a -n/--no-output option, which disables the writing of any .gcov files, so that it emits only the summary info on stdout. This implements the same behaviour in llvm-cov. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208148 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-cov: Fix handling of line zero appearing in a line tableJustin Bogner2014-05-02
| | | | | | | | | | | | | Reading line tables in llvm-cov was pretty broken, but would happen to work as long as no line in the table was 0. It's not clear to me whether a line of zero *should* show up in these tables, but deciding to read a string in the middle of the line table is certainly the wrong thing to do if it does. I've also added some comments, as trying to figure out what this block of code was doing was fairly unpleasant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207866 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-cov: Add support for gcov's --long-file-names optionJustin Bogner2014-04-23
| | | | | | | | GCOV provides an option to prepend output file names with the source file name, to disambiguate between covered data that's included from multiple sources. Add a flag to llvm-cov that does the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207035 91177308-0d34-0410-b5e6-96231b3b80d8

* ProfileData: Add support for the indexed instrprof formatJustin Bogner2014-04-18
| | | | | | | | This adds support for an indexed instrumentation based profiling format, which is just a small header and an on disk hash table.

* tools: fix heap-buffer-overrun detected via ASANSaleem Abdulrasool2014-04-14
| | | | | | | | | | Once the auxiliary fields relating to the filename have been inspected, any following auxiliary fields need not be visited as they have been consumed (the following fields comprise the filepath as a single unit). Adjust the test to catch this even if ASAN is not enabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206190 91177308-0d34-0410-b5e6-96231b3b80d8
* tools: address possible non-null terminated filenamesSaleem Abdulrasool2014-04-14
| | | | | | | | | If a filename is a multiple of 18 characters, there will be no null-terminator. This will result in an invalid access by the constructed StringRef. Add a test case to exercise this and fix that handling. Address this same vulnerability in llvm-readobj as well. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206145 91177308-0d34-0410-b5e6-96231b3b80d8
* tools: teach objdump about FILE aux recordsSaleem Abdulrasool2014-04-13
| | | | | | | | | Add support for file auxiliary symbol entries in COFF symbol tables. A COFF symbol table with a FILE entry is followed by sizeof(__FILE__) / 18 auxiliary symbol records which contain the filename. Read them and form the original filename that the record contains. Then display the name in the output. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@206126 91177308-0d34-0410-b5e6-96231b3b80d8

* InstrProf: Check pointer size in raw profileDuncan P. N. Exon Smith2014-03-23
| | | | | | | | | | | | | | | Since the profile can come from 32-bit machines, we need to check the pointer size. Change the magic number to facilitate this. Adds tests for reading 32-bit and 64-bit binaries (both big- and little-endian). The tests write a binary using printf in RUN lines (like raw-magic-but-no-header.test). Assuming the bots don't complain, this seems like a better way forward for testing RawInstrProfReader than committing binary files. <rdar://problem/16400648> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204557 91177308-0d34-0410-b5e6-96231b3b80d8

* ProfileData: Introduce InstrProfWriter using the naive text formatJustin Bogner2014-03-21
| | | | | | | | | | | This isn't a format we'll want to write out in practice, but moving it to the writer library simplifies llvm-profdata and isolates it from further changes to the format.

| | | | | | | | | | This introduces the ProfileData library and updates llvm-profdata to use this library for reading profiles.

* Object/COFF: Support large relocation table.Rui Ueyama2014-03-21
| | | | | | | | | | | | | | | | NumberOfRelocations field in COFF section table is only 16-bit wide. If an object has more than 65535 relocations, the number of relocations is stored to VirtualAddress field in the first relocation field, and a special flag (IMAGE_SCN_LNK_NRELOC_OVFL) is set to Characteristics field. In test we cheated a bit. I made up a test file so that it has IMAGE_SCN_LNK_NRELOC_OVFL flag but the number of relocations is much smaller than 65535. This is to avoid checking in a large test file just to test a file with many relocations.

* llvm-objdump: Print x64 unwind info in executable.Rui Ueyama2014-03-04
| | | | | | | | | | | | | | | | | | The original code does not work correctly on executable files because the code is written in such a way that only object files are assumed to be given to llvm-objdump. Contents of RuntimeFunction are different between executables and objects. In executables, fields in RuntimeFunction have actual addresses to unwind info structures. On the other hand, in object files, the fields have zero value, but instead there are relocations pointing to the fields, so that Linker will fill them at link-time. So, when we are reading an object file, we need to use relocation info to find the location of unwind info. When executable, we should just look at the values in RuntimeFunction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202785 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | COFF object files with 0 as string table size are currently rejected.
