build: compile with C++20 (#441)
* build using c++20 std=c++20 is used by both v8 and Envoy. Switching to use it is necessary to build with more recent versions of v8, and will also reduce overall build surprises when importing proxy-wasm-cpp-host into Envoy. Signed-off-by: Michael Warres <[email protected]> * change --config=clang-asan-strict to --config=clang-asan Signed-off-by: Michael Warres <[email protected]> * chore: support clang-18 and ubuntu-24.04 These changes make Proxy-Wasm build cleanly with clang-18 and pass clang-tidy-18 checks. Signed-off-by: Matt Leon <[email protected]> * chore: ignore c++20 + clang-18 + gcc-14 findings Signed-off-by: Matt Leon <[email protected]> --------- Signed-off-by: Michael Warres <[email protected]> Signed-off-by: Matt Leon <[email protected]> Co-authored-by: Michael Warres <[email protected]>
