* Make wasm-as emit the names section/debug info only with -g (#705)Alon Zakai2016-09-261-1/+6
|
* Update binary encodings for call instructions and segments (#706)Derek Schuff2016-09-221-9/+10
| | | | | * Call instructions no longer encode the arity * Segments encode the linear memory index (0 for MVP)
* Update binary format toward 0xc (#704)Derek Schuff2016-09-221-88/+137
| | | | | | Updates section headers and formats for type, import, function, table, memory, and export sections, as well as "names" section, which is now a user section.

* use globals in asm2wasmAlon Zakai2016-09-071-7/+42
|
* get_global and set_global use a Name instead of an Index, to be more ↵Alon Zakai2016-09-071-7/+7
| | | | consistent with refering to other global objects; e.g. this avoids ordering issues with imported vs non-imported globals

|
* add shared-constants.h for wasm constantsAlon Zakai2016-06-261-11/+11
|
* Add mode to wasm validator to check for web-environment constraints (#584)Derek Schuff2016-06-141-4/+0
| | | | | | | In the web embedding, modules are not allowed to import or export functions which have i64 params or return values. Add a mode to the validator to check for this, and add flags to s2wasm and wasm-as to enable or disable this check. Also add tests.
* use WASM_UNUSED in some places to fix compiler warning/error on unused ↵Alon Zakai2016-06-081-0/+5
| | | | variables we only use in asserts (#579)
* make call_indirect type a name, so that it is not a dependency on the ↵Alon Zakai2016-06-031-4/+5
| | | | module, which would break consistency and make some parallel passes tricky (#568)
* fix bugs found using afl (#546)Dominic Chen2016-05-311-4/+9

* | Use a class with implicit overflow checks for Address (#486)Derek Schuff2016-05-121-1/+1
|/ | | | It includes implicit conversion from u64 and implicit conversion to address_t. This makes it easier to use without ugly casting and but still gets the overflow checks.
* add error handling for binary errors in new spec testAlon Zakai2016-05-091-7/+7
|
* allow error handling in binary parsingAlon Zakai2016-05-091-1/+2
|
* Harmonize the internal opcodes with the binary format (#433)Alon Zakai2016-05-031-30/+40
| | | | | | * harmonize the internal opcodes with the binary format, so they clearly parallel, and also this helps us avoid needing the type to disambiguate * comment on GetLocal in C API
* Check LEB128 encoding fits in destination integer (#408)JF Bastien2016-04-301-7/+23
| | | | | | | | | | | * Check LEB128 encoding fits in destination integer As found by #404, the insignificant LEB128 bits were silently dropped when dealing with signed LEB values which tripped UBSAN in hello_world. This fixes #409. * Fix typo.
* validate in binaryen shell and on wasm binaries, and fix type checkingAlon Zakai2016-04-291-0/+6

| | | | types, can more simply be held by unique_ptrs on the owning module. this avoids need to coordinate arena allocation for their elements, and only the far more plentiful expression nodes are a perf factor anyhow
* Remove UB (#405)JF Bastien2016-04-271-8/+6
