* llvm-cov: Ignore missing .gcda filesJustin Bogner2014-02-04
| | | | | | | | When gcov is run without gcda data, it acts as if the counts are all zero and labels the file as - to indicate that there was no data. We should do the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200740 91177308-0d34-0410-b5e6-96231b3b80d8

* tools: add support for decoding ARM attributesSaleem Abdulrasool2014-01-30
| | | | | | | | Enhance the ARM specific parsing support in llvm-readobj to support attributes. This allows for simpler tests to validate encoding of the build attributes as specified in the ARM ELF specification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200450 91177308-0d34-0410-b5e6-96231b3b80d8
* Simplify the handling of iterators in ObjectFile.Rafael Espindola2014-01-30
| | | | | | | | | | | | None of the object file formats reported error on iterator increment. In retrospect, that is not too surprising: no object format stores symbols or sections in a linked list or other structure that requires chasing pointers. As a consequence, all error checking can be done on begin() and end(). This reduces the text segment of bin/llvm-readobj in my machine from 521233 to 518526 bytes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200442 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-cov: Accept the long forms of gcov optionsJustin Bogner2014-01-29
| | | | | | | | | This is a bit imperfect, as these options don't show up in the help as is and single dash variants are accepted, which differs from gcov. Unfortunately, this seems to be as good as it gets with the cl::opt machinery, so it'll do as an incremental step. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200419 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-cov: Expect a source file as a positional parameterJustin Bogner2014-01-29
| | | | | | | | | | | Currently, llvm-cov isn't command-line compatible with gcov, which accepts a source file name as its first parameter and infers the gcno and gcda file names from that. This change keeps our -gcda and -gcno options available for convenience in overriding this behaviour, but adds the required parameter and inference behaviour as a compatible default. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200417 91177308-0d34-0410-b5e6-96231b3b80d8

* COFF: Add a missing enum value for high entropy ASLR.Rui Ueyama2014-01-26
| | | | | | | | | That bit is not documented in the PE/COFF spec published by Microsoft, so we don't know the official name of it. I named this bit IMAGE_DLL_CHARACTERISTICS_HIGH_ENTROPY_VIRTUAL_ADDRESS because the bit is reported as "high entropy virtual address" by dumpbin.exe, git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200121 91177308-0d34-0410-b5e6-96231b3b80d8
* llvm-readobj: add support for PE32+ (Windows 64 bit executable).Rui Ueyama2014-01-26
| | | | | | | | | | | | PE32+ supports 64 bit address space, but the file format remains 32 bit. So its file format is pretty similar to PE32 (32 bit executable). The differences compared to PE32 are (1) the lack of "BaseOfData" field and (2) some of its data members are 64 bit. In this patch, I added a new member function to get a PE32+ Header object to COFFObjectFile class and made llvm-readobj to use it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200117 91177308-0d34-0410-b5e6-96231b3b80d8
* Fix "llvm-objdump -d -r" to show relocations inline for ELF filesMark Seaborn2014-01-25
| | | | | | | | | | | | | | | | | | | This fixes a regression introduced by r182908, which broke llvm-objdump's ability to display relocations inline in a disassembly dump for ELF object files. That change removed a SectionRelocMap from Object/ELF.h, which we recreate in llvm-objdump.cpp. I discovered this regression via an out-of-tree test (test/NaCl/X86/pnacl-hides-sandbox-x86-64.ll) which used llvm-objdump. Note that the "Unknown" string in the test output on i386 isn't quite right, but this appears to be a pre-existing bug.

* Be a bit more consistent about using ErrorOr when constructing Binary objects.Rafael Espindola2014-01-21
| | | | | | | | | | | | | | | | | | | | | | | The constructors of classes deriving from Binary normally take an error_code as an argument to the constructor. My original intent was to change them to have a trivial constructor and move the initial parsing logic to a static method returning an ErrorOr. I changed my mind because: * A constructor with an error_code out parameter is extremely convenient from the implementation side. We can incrementally construct the object and give up when we find an error. * It is very efficient when constructing on the stack or when there is no error. The only inefficient case is where heap allocating and an error is found (we have to free the memory). The result is that this is a much smaller patch. It just standardizes the create* helpers to return an ErrorOr. Almost no functionality change: The only difference is that this found that we were trying to read past the end of COFF import library but ignoring the error. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199770 91177308-0d34-0410-b5e6-96231b3b80d8
