* Create .symtab_shndxr only when needed.Rafael Espindola2014-03-25
| | | | | | | | | | | | | | | | | | | | | | | We need .symtab_shndxr if and only if a symbol references a section with an index >= 0xff00. The old code was trying to figure out if the section was needed ahead of time, making it a fairly dependent on the code actually writing the table. It was also somewhat conservative and would create the section in cases where it was not needed. If I remember correctly, the old structure was there so that the sections were created in the same order gas creates them. That was valuable when MC's support for ELF was new and we tested with elf-dump.py. This patch refactors the symbol table creation to another class and makes it obvious that .symtab_shndxr is really only created when we are about to output a reference to a section index >= 0xff00. While here, also improve the tests to use macros. One file is one section short of needing .symtab_shndxr, the second one has just the right number. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204769 91177308-0d34-0410-b5e6-96231b3b80d8

* 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.

* 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-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
