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

[WebAssembly] Merge used feature sets, update atomics linkage policy Summary: It does not currently make sense to use WebAssembly features in some functions but not others, so this CL adds an IR pass that takes the union of all used feature sets and applies it to each function in the module. This allows us to prevent atomics from being lowered away if some function has opted in to using them. When atomics is not enabled anywhere, we detect whether there exists any atomic operations or thread local storage that would be stripped and disallow linking with objects that contain atomics if and only if atomics or tls are stripped. When atomics is enabled, mark it as used but do not require it of other objects in the link. These changes allow libraries that do not use atomics to be built once and linked into both single-threaded and multithreaded binaries.

These relocations are of type R_WEBASSEMBLY_GLOBAL_INDEX_LEB. This change also adds support for reading relocations of this type in WasmObjectFile.cpp. Since its a globally imported symbol this does mean that the get_global/set_global instruction won't be valid until the objects are linked that global used in no longer an imported global.

But currently we only store exception info in this section.) The event section is added between the global section and the export section. This is for ease of validation per request of the V8 team. This patch: - Creates the event symbol type, which is a weak symbol - Makes 'throw' instruction take the event symbol '__cpp_exception' - Adds relocation support for events - Adds WasmObjectWriter / WasmObjectFile (Reader) support - Adds obj2yaml / yaml2obj support - Adds '.eventtype' printing support Reviewers: dschuff, sbc100, aardappel Subscribers: jgravelle-google, sunfish, llvm-commits Differential Revision: https://reviews.llvm.org/D54096 llvm-svn: 346825

[WebAssembly] Initial implementation of PIC code generation This change implements lowering of references global symbols in PIC mode. This change implements lowering of global references in PIC mode using a new @GOT reference type. @GOT references can be used with function or data symbol names combined with the get_global instruction. In this case the linker will insert the wasm global that stores the address of the symbol (either in memory for data symbols or in the wasm table for function symbols). For now I'm continuing to use the R_WASM_GLOBAL_INDEX_LEB relocation type for this type of reference which means that this relocation type can refer to either a global or a function or data symbol. We could choose to introduce specific relocation types for GOT entries in the future.

Follow-up patches will implement a real AsmPrinter, which will require adding MI opcodes specific to WebAssembly.

[WebAssembly] Support CFI for WebAssembly target Summary: This patch implements CFI for WebAssembly. It modifies the LowerTypeTest pass to pre-assign table indexes to functions that are called indirectly, and lowers type checks to test against the appropriate table indexes. It also modifies the WebAssembly backend to support a special ".indidx" assembly directive that propagates the table index assignments out to the linker.

[WebAssemby] Implement block signatures. Per spec changes, this implements block signatures, and adds just enough logic to produce correct block signatures at the ends of functions. Differential Revision: https://reviews.llvm.org/D25144 llvm-svn: 283503

Reland "[WebAssembly] More uses of uint8_t for single byte values" Summary: Original change was D43991 (rL326541) and was reverted by rL326571 and rL326572. This adds also the necessary MCCodeEmitter patch.

[WebAssembly] Replace SIMD expression types with V128 Summary: The spec only defines a SIMD expression type of V128 and leaves interpretation of different vector types to the instructions. Differential Revision: https://reviews.llvm.org/D50367 Patch by Thomas Lively llvm-svn: 339082

[WebAssembly] made assembler parse block_type Summary: This was previously ignored and an incorrect value generated. Also fixed Disassembler's handling of block_type.

[WebAssembly] Add an option to make get_local/set_local explicit. This patch adds a pass, controlled by an option and off by default for now, for making implicit get_local/set_local explicit. This simplifies emitting wasm with MC. Differential Revision: https://reviews.llvm.org/D25836 llvm-svn: 285009

[WebAssembly] Implement more WebAssembly binary encoding. This changes locals from being declared by the emitLocal hook in WebAssemblyTargetStreamer, rather than with an instruction. After exploring the infastructure in LLVM more, this seems to make more sense since declaring locals doesn't use an encoded opcode. This also adds more 0xd opcodes, type encodings, and miscellaneous binary encoding bits. llvm-svn: 285040

[WebAssembly] Use LEB encoding for value types Previously we were using the encoded LEB hex values for the value types. This change uses the decoded negative value and the LEB encoder to write them out. Differential Revision: https://reviews.llvm.org/D30847 Patch by Sam Clegg llvm-svn: 297777
