* Update the file headers across all of the LLVM projects in the monorepoChandler Carruth2019-01-191-4/+3
| | | | | | | | | | | | | | | | | to reflect the new license. We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach. Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository. llvm-svn: 351636
* [llvm-readobj][ELF]Add demangling supportJames Henderson2019-01-171-0/+6
| | | | | | | | | | | | | | | | | | | | | This change adds demangling support to the ELF side of llvm-readobj, under the switch --demangle/-C. The following places are demangled: symbol table dumps (static and dynamic), relocation dumps (static and dynamic), addrsig dumps, call graph profile dumps, and group section signature symbols. Although GNU readelf doesn't support demangling, it is still a useful feature to have, and brings it on a par with llvm-objdump's capabilities. This fixes https://bugs.llvm.org/show_bug.cgi?id=40054.

* [llvm-readelf] Allow single-letter flags to be merged.Jordan Rupprecht2019-01-151-17/+32
| | | | | | | | | | | | | | | | | | | Summary: This patch adds support for merged arguments (e.g. -SW == -S -W) for llvm-readelf. No changes are intended for llvm-readobj. There are a few short flags (-sd, -sr, -st, -dt) that would conflict with grouped single letter flags, and having only some grouped flags might be confusing. So, allow merged flags for readelf compatibility, but force separate args for llvm-readobj. From what I can tell, these two-letter flags are only used with llvm-readobj, not llvm-readelf. This fixes PR40064. Reviewers: jhenderson, kristina, echristo, phosek Reviewed By: jhenderson Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D56629 llvm-svn: 351205

* CodeGen: support an extension to pass linker options on ELFSaleem Abdulrasool2018-01-301-0/+7
| | | | | | | | | | | | | | | | | | Introduce an extension to support passing linker options to the linker. These would be ignored by older linkers, but newer linkers which support this feature would be able to process the linker. Emit a special discarded section `.linker-option`. The content of this section is a pair of strings (key, value). The key is a type identifier for the parameter. This allows for an argument free parameter that will be processed by the linker with the value being the parameter. As an example, `lib` identifies a library to be linked against, traditionally the `-l` argument for Unix-based linkers with the parameter being the library name. Thanks to James Henderson, Cary Coutant, Rafael Espinolda, Sean Silva for the valuable discussion on the design of this feature. llvm-svn: 323783

* [CodeView] Decouple record deserialization from visitor dispatch.Zachary Turner2016-08-051-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Until now, our use case for the visitor has been to take a stream of bytes representing a type stream, deserialize the records in sequence, and do something with them, where "something" is determined by how the user implements a particular set of callbacks on an abstract class. For actually writing PDBs, however, we want to do the reverse. We have some kind of description of the list of records in their in-memory format, and we want to process each one. Perhaps by serializing them to a byte stream, or perhaps by converting them from one description format (Yaml) to another (in-memory representation). This was difficult in the current model because deserialization and invoking the callbacks were tightly coupled. With this patch we change this so that TypeDeserializer is itself an implementation of the particular set of callbacks. This decouples deserialization from the iteration over a list of records and invocation of the callbacks. TypeDeserializer is initialized with another implementation of the callback interface, so that upon deserialization it can pass the deserialized record through to the next set of callbacks. In a sense this is like an implementation of the Decorator design pattern, where the Deserializer is a decorator. This will be useful for writing Pdbs from yaml, where we have a description of the type records in Yaml format. In this case, the visitor implementation would have each visitation callback method implemented in such a way as to extract the proper set of fields from the Yaml, and it could maintain state that builds up a list of these records. Finally at the end we can pass this information through to another set of callbacks which serializes them into a byte stream.

If iterator increment fails (because the archive header is damaged) the iterator will be set to 'end()', and the error stored in the given Error&. The Error value should be checked by the user immediately after the loop. E.g.: Error Err; for (auto &C : A->children(Err)) { // Do something with archive child C. } // Check the error immediately after the loop. if (Err) return Err; Failure to check the Error will result in an abort() when the Error goes out of scope (as guaranteed by the Error class). llvm-svn: 275316

Changed getAsArchive() from ErrorOr<...> to Expected<...> so now all interfaces there use the new llvm::Error model for return values. In the two places it had if (!Parent) this is actually a program error so changed from returning errorCodeToError(object_error::parse_failed) to calling report_fatal_error() with a message. In getObjectForArch() added error messages to its two llvm::Error return values instead of returning errorCodeToError(object_error::arch_not_found) with no error message. For the llvm-obdump, llvm-nm and llvm-size clients since the only binary files in Mach-O Universal Binaries that are supported are Mach-O files or archives with Mach-O objects, updated their logic to generate an error when a slice contains something like an ELF binary instead of ignoring it. And added a test case for that. The last error stuff to be cleaned up for libObject’s MachOUniversalBinary is the use of errorOrToExpected(Archive::create(ObjBuffer)) which needs Archive::create() to be changed from ErrorOr<...> to Expected<...> first, which I’ll work on next. llvm-svn: 274079
