Wasm stubs (C to Wasm and Wasm to JS) aren't logged, so they show up as ??? in GDB backtraces. Emit a CodeCreateEvent in the finalization phase of the compilation job so that the JitCodeLogger can keep track of it. With this, a backtrace shows up like (truncated): -(gdb) bt -#0 v8::internal::Runtime_WasmArrayCopy -#1 0x00007fc69d2e155f in Builtins_CEntry_Return1_DontSaveFPRegs_ArgvOnStack_NoBuiltinExit -#2 0x00001c368159fcfc in Function:wasm-function[0]-0-turbofan -#3 0x000000fa00044096 in Stub:c-wasm-entry:i:i -#4 0x00007fc69dc76b76 in v8::internal::GeneratedCode -#5 0x00007fc69dc75b25 in v8::internal::Execution::CallWasm -#6 0x000056506d1a2b6b in v8::internal::wasm::test_gc::WasmGCTester::CallFunctionImpl Bug: v8:11908 Change-Id: I1223b496091f99a94f2e4e665831462cc9617286 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/3109050 Reviewed-by: Clemens Backes <clemensb@chromium.org> Reviewed-by: Georg Neis <neis@chromium.org> Commit-Queue: Zhi An Ng <zhin@chromium.org> Cr-Commit-Position: refs/heads/main@{#76608} |
