|/ | | | | ubsan fails with: wasm-binary.h:97:32: runtime error: left shift of negative value -1 Also use type_traits for is_signed.
* Split construction, scanning, and building phases of S2WasmBuilder (#400)Derek Schuff2016-04-2713-80/+250
| | | | | | | | | | | Instead of doing all of the S2Wasm work in the constructor, split construction, scanning (to determine implemented functions) and building of the wasm module. This allows the linker to get the symbol information (e.g. implemented functions) without having to build an entire module (which will be useful for archives) and to allow the linker to link a new object into the existing one by building the wasm module in place on the existing module.

* Defer creation of CallImports to link time (#395)Derek Schuff2016-04-263-21/+41
| | | s2wasm currently creates a Call AST node if the target is implemented in the current object (thus far assumed to be the final executable) and a CallImport node if not. In preparation for adding additional objects to the link before layout time, we make only Call nodes until link time, and then convert them to CallImport if they are undefined at that time.

* Separate LinkerObject from Linker (#383)Derek Schuff2016-04-254-141/+171
| | | | | Create the LinkerObject class, which has a wasm Module and represents the module plus the information needed to relocate and lay it out. Each Linker owns a "main executable" LinkerObject, and S2WasmBuilder requires a LinkerObject instead of just a Module because LLVM asm files require relocation/linking before they represent a full wasm module. No merging support yet, but the real functionality for #370 is coming soon.
