* Move Object format code to lib/BinaryFormat.Zachary Turner2017-06-071-1/+1
| | | | | | | | | | | | This creates a new library called BinaryFormat that has all of the headers from llvm/Support containing structure and layout definitions for various types of binary formats like dwarf, coff, elf, etc as well as the code for identifying a file from its magic.

* Sort the remaining #include lines in include/... and lib/....Chandler Carruth2017-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | I did this a long time ago with a janky python script, but now clang-format has built-in support for this. I fed clang-format every line with a #include and let it re-sort things according to the precise LLVM rules for include ordering baked into clang-format these days. I've reverted a number of files where the results of sorting includes isn't healthy. Either places where we have legacy code relying on particular include ordering (where possible, I'll fix these separately) or where we have particular formatting around #include lines that I didn't want to disturb in this patch. This patch is *entirely* mechanical. If you get merge conflicts or anything, just ignore the changes in this patch and run clang-format over your #include lines in the files. Sorry for any noise here, but it is important to keep these things stable. I was seeing an increasing number of patches with irrelevant re-ordering of #include lines because clang-format was used. This patch at least isolates that churn, makes it easy to skip when resolving conflicts, and gets us to a clean baseline (again). llvm-svn: 304787
* [ARM] Fix handling of mapping symbols when changing sectionsJohn Brawn2017-04-201-1/+1
| | | | | | | | | | | ChangeSection incorrectly registers LastEMSInfo as belonging to the previous section, not the current section. This happens to work when changing sections using .section, as the previous section is set to the current section before the call to ChangeSection, but not when using .popsection.

* Change how we handle section symbols on ELF.Rafael Espindola2017-02-021-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | On ELF every section can have a corresponding section symbol. When in an assembly file we have .quad .text the '.text' refers to that symbol. The way we used to handle them is to leave .text an undefined symbol until the very end when the object writer would map them to the actual section symbol. The problem with that is that anything before the end would see an undefined symbol. This could result in bad diagnostics (test/MC/AArch64/label-arithmetic-diags-elf.s), or incorrect results when using the asm streamer (est/MC/Mips/expansion-jal-sym-pic.s). Fixing this will also allow using the section symbol earlier for setting sh_link of SHF_METADATA sections. This patch includes a few hacks to avoid changing our behaviour when handling conflicts between section symbols and other symbols. I reported pr31850 to track that. llvm-svn: 293936

| | | | | | | | | | | | | | | | | | | | | | | Summary: This fixes three bugs, in all of which state is not or incorrecly reset between objects (i.e. when reusing the same pass manager to create multiple object files): 1) AttributeSection needs to be reset to nullptr, because otherwise the backend will try to emit into the old object file's attribute section causing a segmentation fault. 2) MappingSymbolCounter needs to be reset, otherwise the second object file will start where the first one left off. 3) The MCStreamer base class resets the Streamer's e_flags settings. Since EF_ARM_EABI_VER5 is set on streamer creation, we need to set it again after the MCStreamer was rest. Also rename Reset (uppser case) to EHReset to avoid confusion with reset (lower case).

* Handle ARMv6-J as an alias, instead of fake architectureArtyom Skrobov2015-11-201-1/+0
| | | | | | | | | | | | | | | | | | | | | | Summary: This follows D14577 to treat ARMv6-J as an alias for ARMv6, instead of an architecture in its own right. The functional change is that the default CPU when targeting ARMv6-J changes from arm1136j-s to arm1136jf-s, which is currently used as the default CPU for ARMv6; both are, in fact, ARMv6-J CPUs. The J-bit (Jazelle support) is irrelevant to LLVM, and it doesn't affect code generation, attributes, optimizations, or anything else, apart from selecting the default CPU.

* Stop producing .data.rel sections.Rafael Espindola2015-11-181-9/+4
| | | | | | | | | | | | | | | | | If a section is rw, it is irrelevant if the dynamic linker will write to it or not. It looks like llvm implemented this because gcc was doing it. It looks like gcc implemented this in the hope that it would put all the relocated items close together and speed up the dynamic linker. There are two problem with this: * It doesn't work. Both bfd and gold will map .data.rel to .data and concatenate the input sections in the order they are seen. * If we want a feature like that, it can be implemented directly in the linker since it knowns where the dynamic relocations are. llvm-svn: 253436
* [Assembler] Make fatal assembler errors non-fatalOliver Stannard2015-11-171-2/+4
| | | | | | | | | | | | | | Currently, if the assembler encounters an error after parsing (such as an out-of-range fixup), it reports this as a fatal error, and so stops after the first error. However, for most of these there is an obvious way to recover after emitting the error, such as emitting the fixup with a value of zero. This means that we can report on all of the errors in a file, not just the first one. MCContext::reportError records the fact that an error was encountered, so we won't actually emit an object file with the incorrect contents.

The ARM and AArch64 assembly parsers were not setting this, so error messages did not have source information. Differential Revision: http://reviews.llvm.org/D14645 llvm-svn: 253219

| | | | | | | | | | | | | | | | | | | | | | | | | | | | and related. NFC. Summary: This is the first patch in the series to migrate Triple's (which are ambiguous) to TargetTuple's (which aren't). For the moment, TargetTuple simply passes all requests to the Triple object it holds. Once it has replaced Triple, it will start to implement the interface in a more suitable way. This change makes some changes to the public C++ API. In particular, InitMCSubtargetInfo(), createMCRelocationInfo(), and createMCSymbolizer() now take TargetTuples instead of Triples. The other public C++ API's have been left as-is for the moment to reduce patch size. This commit also contains a trivial patch to clang to account for the C++ API change.

| | | | | | | | | | | | | | | Now that most of the methods in Clang and LLVM that were parsing arch/cpu/fpu strings are using ARMTargetParser, it's time to make it a bit more conforming with what the ABI says. This commit adds some clarification on what build attributes are accepted and which are "non-standard". It also makes clear that the "defaultCPU" and "defaultArch" methods were really just build attribute getters. It also diverges from GCC's behaviour to say that armv2/armv3 are really an ARMv4 in the build attributes, when the ABI has a clear state for that: Pre-v4. llvm-svn: 238344

There are a few issues with the current split between MCSection and MCSectionData. * It optimizes the the not as important case. We want the production of .o files to be really fast, but the split puts the information used for .o emission in a separate data structure. * The ELF/COFF/MachO hierarchy is not represented in MCSectionData, leading to some ad-hoc ways to represent the various flags. * It makes it harder to remember where each item is. The attached patch starts merging the two by moving the alignment from MCSectionData to MCSection.
