* In AsmConstWalker, don't assume a segment exists (#697)jgravelle-google2016-09-141-2/+10
| | | | | | | | | | It's possible to generate an EM_ASM call with empty contents (due to ifdefs, for example), and this gets converted to an empty string. AsmConstWalker assumes that by this point any addresses it is pointing to have a corresponding data section, which is reasonable. However in the case of an empty string, we don't create a data section, but just leave that address uninitialized, i.e. set to 0. In the case of AsmConstWalker, a correct thing to do is to emit the empty string as metadata, which becomes an empty emscripten_asm_v call.
* Add flag to s2wasm to export __growWasmMemory function (#696)jgravelle-google2016-09-091-0/+208
* Add a flag to s2wasm to export grow_memory Binaryen's wasm.js-post.js calls back in to wasm in order to grow the linear memory, via a function that asm2wasm exports called __growWasmMemory. This changes exposes that method through s2wasm when invoked with a flag. * Move AsmConstWalker from wasm-linker to wasm-emscripten * Add test for memory growth in s2wasm * Move makeDynCallThunks into wasm-emscripten module * Move mutation in getTableSegment into a separate method * Move emscripten metadata generation into wasm-emscripten Also make AsmConstWalker internal to the wasm-emscripten module, as it's only used for the metadata pass.
