[WebAssembly] Use inline target tripple in test cases This is somewhat preferable since (in many cases) it allows llc to be run directly on the .ll files without having to pass the `-mtriple` argument. Differential Revision: https://reviews.llvm.org/D42438 llvm-svn: 323299

[WebAssembly] Check function signatures by default But only produce a warning (for now) unless --fatal-warnings is passed. Differential Revision: https://reviews.llvm.org/D46484 llvm-svn: 331574

[WebAssembly] Add --export flag to force a symbol to be exported This is useful for emscripten or other tools that want to selectively exports symbols without necessarily changing the source code. Differential Revision: https://reviews.llvm.org/D42003 llvm-svn: 322408

[WebAssembly] Define __heap_base global This is an immutable exported global representing the start of the heap area. It is a page aligned. Differential Revision: https://reviews.llvm.org/D42030 llvm-svn: 322609

[WebAssembly] Add __data_end link-sythentic symbol. This is similar to _end (See https://linux.die.net/man/3/edata for more) but using our own unique name since our use cases will most likely be different and we want to keep our options open WRT to memory layout. This change will allow is to remove the DataSize from the linking metadata section which is currently being used by emscripten to derive the end of the data.

[WebAssembly] Reorder synthetic functions to come first This matches the existing ordering that's been there for globals for a while (__stack_pointer coming first). Differential Revision: https://reviews.llvm.org/D44333 llvm-svn: 327286

[WebAssembly] Don't error when --undefined symbols are not found This matches the behavior of the ELF linker where -u/--undefined means symbols will get pulled in from archives but won't result in link error if they are missing. Also, don't actually great symbol table entries for the undefined symbols, again matching more closely the ELF linker. This also results in simplification of the code.
