| | | | | | | It is mentioned in the LLVM coding standard that _begin() and _end() suffixes should be used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191569 91177308-0d34-0410-b5e6-96231b3b80d8
* Explicitly request unsigned enum types when desiredReid Kleckner2013-09-231-1/+1
| | | | | | | | | | | | | | | | | | | | | The underlying type of all plain enums in MSVC is 'int', even if the enumerator contains large 32-bit unsigned values or values greater than UINT_MAX. The only way to get a large or unsigned enum type is to request it explicitly with the C++11 strong enum types feature. However, since LLVM isn't C++11 yet, I had to add a conditional LLVM_ENUM_INT_TYPE to Compiler.h to control its usage. The motivating true positive for this change is compiling PointerIntPair with MSVC for win64. The PointerIntMask value is supposed to be pointer sized value of all ones with some low zeros. Instead, it's truncated to 32-bits! We are only saved later because it is sign extended back in the AND with int64_t, and we happen to want all ones. This silences lots of -Wmicrosoft warnings during a clang self-host targeting Windows. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191241 91177308-0d34-0410-b5e6-96231b3b80d8
* Handle relocations that don't point to symbols.Rafael Espindola2013-06-051-6/+5
| | | | | | | | In ELF (as in MachO), not all relocations point to symbols. Represent this properly by using a symbol_iterator instead of a SymbolRef. Update llvm-readobj ELF's dumper to handle relocatios without symbols. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@183284 91177308-0d34-0410-b5e6-96231b3b80d8
* Change how we iterate over relocations on ELF.Rafael Espindola2013-05-301-8/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | For COFF and MachO, sections semantically have relocations that apply to them. That is not the case on ELF. In relocatable objects (.o), a section with relocations in ELF has offsets to another section where the relocations should be applied. In dynamic objects and executables, relocations don't have an offset, they have a virtual address. The section sh_info may or may not point to another section, but that is not actually used for resolving the relocations. This patch exposes that in the ObjectFile API. It has the following advantages: * Most (all?) clients can handle this more efficiently. They will normally walk all relocations, so doing an effort to iterate in a particular order doesn't save time. * llvm-readobj now prints relocations in the same way the native readelf does. * probably most important, relocations that don't point to any section are now visible. This is the case of relocations in the rela.dyn section. See the updated relocation-executable.test for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@182908 91177308-0d34-0410-b5e6-96231b3b80d8
* Change getRelocationAdditionalInfo to be ELF only.Rafael Espindola2013-05-091-7/+5
| | | | | | | It was only implemented for ELF where it collected the Addend, so this patch also renames it to getRelocationAddend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181502 91177308-0d34-0410-b5e6-96231b3b80d8
* Add getSymbolAlignment to the ObjectFile interface.Rafael Espindola2013-04-291-0/+7
| | | | | | | | | | | | | For regular object files this is only meaningful for common symbols. An object file format with direct support for atoms should be able to provide alignment information for all symbols. This replaces getCommonSymbolAlignment and fixes test-common-symbols-alignment.ll on darwin. This also includes a fix to MachOObjectFile::getSymbolFlags. It was marking undefined symbols as common (already tested by existing mcjit tests now that it is used). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@180736 91177308-0d34-0410-b5e6-96231b3b80d8

* Remove 'static' from inline functions defined in header files.Chandler Carruth2012-06-201-2/+2
| | | | | | | | | | | | | | | | | There is a pretty staggering amount of this in LLVM's header files, this is not all of the instances I'm afraid. These include all of the functions that (in my build) are used by a non-static inline (or external) function. Specifically, these issues were caught by the new '-Winternal-linkage-in-inline' warning. I'll try to just clean up the remainder of the clearly redundant "static inline" cases on functions (not methods!) defined within headers if I can do so in a reliable way. There were even several cases of a missing 'inline' altogether, or my personal favorite "static bool inline". Go figure. ;] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158800 91177308-0d34-0410-b5e6-96231b3b80d8
