[ObjectYAML] Support Thin MachO headers to YAML This patch adds support to ObjectYAML for serializing mach_header structs. llvm-svn: 269303

//===- MachOYAML.cpp - MachO YAMLIO implementation ------------------------===//
//
Update the file headers across all of the LLVM projects in the monorepo 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

Move Object format code to lib/BinaryFormat. 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.

[obj2yaml] [yaml2obj] Basic support for MachO::load_command This patch adds basic support for MachO::load_command. Load command types and sizes are encoded in the YAML and expanded back into MachO.

In the meantime as a temporary measure when writing MachO files the load commands are padded with zeros so that the generated binary is valid. llvm-svn: 269442

[YAML] Fix YAML tags appearing before the start of sequence elements Our existing yaml::Output code writes tags immediately when mapTag is called, without any state handling. This results in tags on sequence elements being written before the element itself. For example, we see this: SomeArray: !elem_type - key1: 1 key2: 2 !elem_type2 - key3: 3 key4: 4 We should instead see: SomeArray: - !elem_type key1: 1 key2: 2 - !elem_type2 key3: 3 key4: 4 Our reader handles reading properly, so this bug only impacts writing yaml sequences with tagged elements. As a test for this I've modified the Mach-O yaml encoding to allways apply the !mach-o tag when encoding MachOYAML::Object entries. This results in the !mach-o tag appearing as expected in dumped fat files. llvm-svn: 274067

[obj2yaml] [yaml2obj] Support for MachO Load Command data This re-applies r270115. Many of the MachO load commands can have data appended after the command structure. This data is frequently strings, but can actually be anything. This patch adds support for three optional fields on load command yaml descriptions. The new PayloadString YAML field is populated with the data after load commands known to have strings as extra data. The new ZeroPadBytes YAML field is a count of zero'd bytes after the end of the load command structure before the next command. This can apply anywhere in the file. MachO2YAML verifies that bytes are zero before populating this field, and YAML2MachO will add zero'd bytes. The new PayloadBytes YAML field stores all bytes after the end of the load command structure before the next command if they are non-zero. This is a catch all for all unhandled bytes. If MachO2Yaml populates PayloadBytes it will not populate ZeroPadBytes, instead zero'd bytes will be in the PayloadBytes structure. llvm-svn: 270124

In the meantime as a temporary measure when writing MachO files the load commands are padded with zeros so that the generated binary is valid. llvm-svn: 269442
