* Remove section_rel_empty. Just compare begin() and end() instead.Rafael Espindola2014-04-03

* Implement get getSymbolFileOffset with getSymbolAddress.Rafael Espindola2014-04-03
| | | | | | | | | | | | This has the following advantages: * Less code. * The old ELF implementation was wrong for non-relocatable objects. * The old ELF implementation (and I think MachO) was wrong for thumb. No current testcase since this is only used from MCJIT and it only uses relocatable objects and I don't think it supports thumb yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205508 91177308-0d34-0410-b5e6-96231b3b80d8

* [RuntimeDyld] Allow processRelocationRef to process more than one relocation ↵Juergen Ributzka2014-03-21
| | | | | | | | | | | | | entry at a time. Some targets require more than one relocation entry to perform a relocation. This change allows processRelocationRef to process more than one relocation entry at a time by passing the relocation iterator itself instead of just the relocation entry.

* 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.

* Object: Provide a richer means of describing auxiliary symbolsDavid Majnemer2014-03-19
| | | | | | | | | | | | | | | | The current state of affairs has auxiliary symbols described as a big bag of bytes. This is less than satisfying, it detracts from the YAML file as being human readable. Instead, allow for symbols to optionally contain their auxiliary data. This allows us to have a much higher level way of describing things like weak symbols, function definitions and section definitions. This depends on D3105.

* Object/COFF: change data type of SymbolNumber from int16 to uint16.Rui Ueyama2014-03-15
| | | | | | | | | | | | Microsoft PE/COFF Spec clearly states that the field is of signed interger type. However, in reality, it's unsigned. If cl.exe needs to create a large number of sections for COMDAT sections, it will just create more than 32768 sections. Handling large section number as negative number is not correct.

* llvm-objdump/COFF: Print load configuration table.Rui Ueyama2014-02-19
| | | | | | | | | | | | Load Configuration Table may contain a pointer to SEH table. This patch is to print the offset to the table. Printing SEH table contents is a TODO. The layout of Layout Configuration Table is described in Microsoft PE/COFF Object File Format Spec, but the table's offset/size descriptions seems to be totally wrong, at least in revision 8.3 of the spec. I believe the table in this patch is the correct one. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201638 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).

* 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().

* 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
