Implemented the `svm_allocate` host function. adding some debugging printing to the new `svm_allocate` host function. WIP: computing the `returns` byte-size for a function (sdk-macros) * `calldata` is allocated on instance only when non-empty. The `svm-sdk` relies on the host function for Wasm targeted code and on the default global allocator otherwise. adding `svm_sdk_std::panic` (aborts for Wasm and unwinds otherwise) WIP: adding an explicit feature flag for the host static allocation. svm-codec is using the default global-alloactor (not the "static allocation") codec - js tests pass (commenting the `verify_data` for now) tests pass CI - running only on Windows + running the tests 10 times (there seems to be a sporadic failures) CI - skipping the build stage svm-sdk-std: exposing Rust `Vec` svm-sdk-std: using `panic!` running only the `svm-runtime` crate tests. Removing `wabt` (using only `wat`) - it takes much less time to build. using cache action v2 Adding GitHub Action for LLVM Adding caching to the llvm LLVM 10 Returning back the original LLVM action for Windows adding feature-flags `default-cranelift` and `default-llvm` trying to run CI against `llvm` running tests with a single thread runtime - removing two ignored tests related to gas-metering Commenting a test runtime: ignoring all tests except one running tests in dev-mode Building on Linux and macOS svm-sdk-std: returning back Rust `Vec` Commenting part of the problematic test Commenting another part of the problematic test uncomment part of the problematic test cbindgen version bump problemtic test - wasm input file "runtime_calldata.wasm" isn't using the "static-alloc" problemtic test: input wasm is being compiled with less code and no `.cargo/config` file Uncommenting all the problematic test Trying to locate the bug Trying again to pinpoint the bug Adding asserts against setting explicitly empty `returndata` WIP: debugging WIP: debugging... WIP: debugging... skipping the last CI stages for now... WIP: trying to locate the cause of the bug... WIP commenting the "static-alloc" related code from `svm-sdk-alloc` WIP Trying again to make the test fail Trying to figure out whether the #[endpoint] return-type has anything to do with the bug... Commenting "Storage" from the wasm input of the failing test... More debugging the root cause of the problem debugging... adding "Cache workspace" step Splitting cargo caching into isloated steps. adding "Dump GitHub context" step. CI: changing to `crates/runtime` before running the tests Try again to run CI... Try again CI: disabling LLVM installation for now (Windows) Trying again to reproduce a broken CI on Windows... Checking whether the bug has something to do with `svm_sdk::Address` Trying to find a minimal failing input using `Amount` WIP: Debugging... WIP: removing the parameter from the problematic endpoint This should pass (not using `endpoint`) This should fail again... `ExtHost#get_calldata` - returning a static data Re-compile the wasm input Empty `endpoint` prologue. debugging debugging... Trying to narrow the bug WIP Narrowing the epilogue part should fail... Uncommenting part of the epilogue WIP
… the endpoint's macro.

Motivation
This PR builds on top of the two previous PRs:
In high-level, in order to price a program (which has passed validation) we have to:
2.1 Build its CFG
2.2 Find the most expensive execution path in the CFG
3.1 The transaction
CallDatainput3.2 The price of the Wasm instance initiation (it involves
memoryinitialization)3.3 The price of calling
svm_alloc(determined at 2.2) with thebyte sizeof the inputCallData3.4 The price of the invoked function (determined at 2.2)
This PR implements bullets 1. and 2. above.
Implementing 3. and the pricing of
deploy-templateandspawn-apptransactions will be added in a future PR as part of integrating the updatedsvm-gascrate's functionality into thesvm-runtimecrate.
