* Relax COFF string table checkNico Rieck2014-02-26
| | | | | | | | | COFF object files with 0 as string table size are currently rejected. This prevents us from reading object files written by tools like cvtres that violate the PECOFF spec and write 0 instead of 4 for the size of an empty string table. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@202292 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a SymbolicFile interface between Binary and ObjectFile.Rafael Espindola2014-02-21
| | | | | | | | | | | This interface allows IRObjectFile to be implemented without having dummy methods for all section and segment related methods. Both llvm-ar and llvm-nm are changed to use it. Unfortunately the mangler is still not plugged in since it requires some refactoring to make a Module hold a DataLayout. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201881 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm-objdump/COFF: Print SEH table addresses.Rui Ueyama2014-02-20
| | | | | | | SEH table addresses are VA in COFF file. In this patch we convert VA to RVA before printing it, because dumpbin prints them as RVAs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201760 91177308-0d34-0410-b5e6-96231b3b80d8

* Use the information provided by getFlags to unify some code in llvm-nm.Rafael Espindola2014-02-05
| | | | | | | | | | It is not clear how much we should try to expose in getFlags. For example, should there be a SF_Object and a SF_Text? But for information that is already being exposed, we may as well use it in llvm-nm. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200820 91177308-0d34-0410-b5e6-96231b3b80d8

* Simplify getSymbolFlags.Rafael Espindola2014-01-31
| | | | | | | None of the object formats require extra parsing to compute these flags, so the method cannot fail. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200574 91177308-0d34-0410-b5e6-96231b3b80d8
* Only ELF has a dynamic symbol table. Remove it from ObjectFile.Rafael Espindola2014-01-30
| | | | | | | | | COFF has only one symbol table. MachO has a LC_DYSYMTAB, but that is not a symbol table, just extra info about the one symbol table (LC_SYMTAB). IR (coming soon) also has only one table. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200488 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
* Make createObjectFile's signature a bit less error prone.Rafael Espindola2014-01-29
| | | | | | | This will be better with c++11, but right now file_magic converts to bool, which makes the api really easy to misuse. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200357 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

* Pass the computed magic to createBinary and createObjectFile if available.Rafael Espindola2014-01-22
| | | | | | | identify_magic is not free, so we should avoid calling it twice. The argument also makes it cheap for createBinary to just forward to createObjectFile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199813 91177308-0d34-0410-b5e6-96231b3b80d8

* 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

* llmv-objdump/COFF: Print export table contents.Rui Ueyama2014-01-16
| | | | | | | | | | | | | | | | This patch adds the capability to dump export table contents. An example output is this: Export Table: Ordinal RVA Name 5 0x2008 exportfn1 6 0x2010 exportfn2 By adding this feature to llvm-objdump, we will be able to use it to check export table contents in LLD's tests. Currently we are doing binary comparison in the tests, which is fragile and not readable to humans. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199358 91177308-0d34-0410-b5e6-96231b3b80d8
* Don't use DataRefImpl to implement ImportDirectoryEntryRef.Rui Ueyama2014-01-16
| | | | | | | | | DataRefImpl (a union of two integers and a pointer) is not the ideal data type to represent a reference to an import directory entity. We should just use the pointer to the import table and an offset instead to simplify.
