Enhance the hw bound check reported in #1262: When registering signal handlers for SIGSEGV & SIGBUS in boundary check with hardware trap, preserve the previous handlers for signal SIGSEGV and SIGBUS, and forward the signal to the preserved signal handlers if it isn't handled by hw bound check.
Remove unnecessary memset after mmap to decrease the number of page faults, as reported in #1269.
…#1279) Sub module's auxiliary stack boundary and bottom may be different from main module's counterpart, so when calling sub module, its aux stack info should be gotten and set to exec_env firstly, or aux stack overflow and out of bounds memory access exception may be thrown when calling sub module's function. Fix the issue reported in PR #1278.
Fix the issue reported in #1282. When i32/i64 rotate (rotl/rotr) with 0, the LLVM IRs translated are: left<<0 | left>>64 and left >>0 | left<<64 The value of left >> 64 and left <<64 in LLVM are treated as poison, which causes invalid result when executing the aot function. Directly return left when right is 0 to fix the issue.
The existing validation didn't work as expected; e.g. for address pool: 8.8.8.8/24 the application had access to the 127.0.0.1 address (which should not).
Add API wasm_runtime_set_module_inst, per request from #1275
Set noexecstack CXX link flags for wamrc to avoid generating binary with exec stack.
According to import subtyping validation: https://webassembly.github.io/spec/core/valid/types.html#import-subtyping wasm-c-api needs to check types when linking.
Fix libc-wasi poll_oneoff hang issue Fix libc-uvwasi environ_get sanity check issue
Implement boundary check with hardware trap for interpreter on 64-bit platforms: - To improve the performance of interpreter and Fast JIT - To prepare for multi-tier compilation for the feature Linux/MacOS/Windows 64-bit are enabled.
Fix build script to enable hw bound check for interpreter when AOT is disabled, so as to enable spec cases test for interp with hw bound check. And fix the issues found.
