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

Remove \brief commands from doxygen comments. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

[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.

[WebAssembly] v8x16.shuffle Summary: Since the shuffle mask is not exposed as an operand in the native ISel DAG, create a new WebAssembly ISD node exposing the mask. The mask is lowered as sixteen immediate byte indices no matter what type the original vector shuffle was operating on.

[WebAssembly] v8x16.swizzle and rewrite BUILD_VECTOR lowering Summary: Adds the new v8x16.swizzle SIMD instruction as specified at https://github.com/WebAssembly/simd/blob/master/proposals/simd/SIMD.md#swizzling-using-variable-indices. In addition to adding swizzles as a candidate lowering in LowerBUILD_VECTOR, also rewrites and simplifies the lowering to minimize the number of replace_lanes necessary rather than trying to minimize code size. This leads to more uses of v128.const instead of splats, which is expected to increase performance. The new code will be easier to tune once V8 implements all the vector construction operations, and it will also be easier to add new candidate instructions in the future if necessary.

[WebAssembly] Add support for the event section Summary: This adds support for the 'event section' specified in the exception handling proposal. (This was named 'exception section' first, but later renamed to 'event section' to take possibilities of other kinds of events into consideration. 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
