[wasm] Introduce the TrapIf and TrapUnless operators to generate trap code. Some instructions in WebAssembly trap for some inputs, which means that the execution is terminated and (at least at the moment) a JavaScript exception is thrown. Examples for traps are out-of-bounds memory accesses, or integer divisions by zero. Without the TrapIf and TrapUnless operators trap check in WebAssembly introduces 5 TurboFan nodes (branch, if_true, if_false, trap-reason constant, trap-position constant), in addition to the trap condition itself. Additionally, each WebAssembly function has four TurboFan nodes (merge, effect_phi, 2 phis) whose number of inputs is linear to the number of trap checks in the function. Especially for functions with high numbers of trap checks we observe a significant slowdown in compilation time, down to 0.22 MiB/s in the sqlite benchmark instead of the average of 3 MiB/s in other benchmarks. By introducing a TrapIf common operator only a single node is necessary per trap check, in addition to the trap condition. Also the nodes which are shared between trap checks (merge, effect_phi, 2 phis) would disappear. First measurements suggest a speedup of 30-50% on average. This CL only implements TrapIf and TrapUnless on x64. The implementation is also hidden behind the --wasm-trap-if flag. Please take a special look at how the source position is transfered from the instruction selector to the code generator, and at the context that is used for the runtime call.

[wasm] Introduce the TrapIf and TrapUnless operators to generate trap code. Some instructions in WebAssembly trap for some inputs, which means that the execution is terminated and (at least at the moment) a JavaScript exception is thrown. Examples for traps are out-of-bounds memory accesses, or integer divisions by zero. Without the TrapIf and TrapUnless operators trap check in WebAssembly introduces 5 TurboFan nodes (branch, if_true, if_false, trap-reason constant, trap-position constant), in addition to the trap condition itself. Additionally, each WebAssembly function has four TurboFan nodes (merge, effect_phi, 2 phis) whose number of inputs is linear to the number of trap checks in the function. Especially for functions with high numbers of trap checks we observe a significant slowdown in compilation time, down to 0.22 MiB/s in the sqlite benchmark instead of the average of 3 MiB/s in other benchmarks.

X87: Change the test case for X87 Run_WasmF32SConvertI64/Run_WasmF64SConvertI64. The CL #34701 (https://codereview.chromium.org/1779123002/) added the Run_WasmF32SConvertI64/Run_WasmF64SConvertI64 test cases and X87 failed at them. The reason is same as the CL #33630 (Issue 1649323002: X87: Change the test case for X87 RunRoundInt32ToFloat32), please refer: https://codereview.chromium.org/1649323002. Here is the key comments from CL #33630: Some new test cases use CheckFloatEq(...) and CheckDoubleEq(...) function for result check. When GCC compiling the CheckFloatEq() and CheckDoubleEq() function, those inlined functions has different behavior comparing with GCC ia32 build and x87 build. The major difference is sse float register still has single precision rounding semantic. While X87 register has no such rounding precsion semantic when directly use register value. The V8 turbofan JITTed has exactly same result in both X87 and IA32 port. For CHECK_EQ(a, b) function, if a and b are double or float, it will has similar behaviors like CheckFloatEq(...) and CheckDoubleEq(...) function when compiled by GCC and causes the test case fail. So we add the following sentence to do type case to keep the same precision for Run_WasmF32SConvertI64/Run_WasmF64SConvertI64. Such as: volatile double expect = static_cast<float>(*i). ahaas put those codes in CHECK_FLOAT_EQ and CHECK_DOUBLE_EQ macros in CL #34534 (https://codereview.chromium.org/1773513002 ). So this CL replaced the CHECK_EQ in Run_WasmF32SConvertI64/Run_WasmF64SConvertI64 to CHECK_FLOAT_EQ/CHECK_DOUBLE_EQ for x87 can pass Run_WasmF32SConvertI64/Run_WasmF64SConvertI64 tests.

X87: Change the test case for X87 Run_WasmF32SConvertI64/Run_WasmF64SConvertI64. The CL #34701 (https://codereview.chromium.org/1779123002/) added the Run_WasmF32SConvertI64/Run_WasmF64SConvertI64 test cases and X87 failed at them. The reason is same as the CL #33630 (Issue 1649323002: X87: Change the test case for X87 RunRoundInt32ToFloat32), please refer: https://codereview.chromium.org/1649323002. Here is the key comments from CL #33630: Some new test cases use CheckFloatEq(...) and CheckDoubleEq(...) function for result check. When GCC compiling the CheckFloatEq() and CheckDoubleEq() function, those inlined functions has different behavior comparing with GCC ia32 build and x87 build. The major difference is sse float register still has single precision rounding semantic. While X87 register has no such rounding precsion semantic when directly use register value. The V8 turbofan JITTed has exactly same result in both X87 and IA32 port. For CHECK_EQ(a, b) function, if a and b are double or float, it will has similar behaviors like CheckFloatEq(...) and CheckDoubleEq(...) function when compiled by GCC and causes the test case fail. So we add the following sentence to do type case to keep the same precision for Run_WasmF32SConvertI64/Run_WasmF64SConvertI64. Such as: volatile double expect = static_cast<float>(*i). ahaas put those codes in CHECK_FLOAT_EQ and CHECK_DOUBLE_EQ macros in CL #34534 (https://codereview.chromium.org/1773513002 ). So this CL replaced the CHECK_EQ in Run_WasmF32SConvertI64/Run_WasmF64SConvertI64 to CHECK_FLOAT_EQ/CHECK_DOUBLE_EQ for x87 can pass Run_WasmF32SConvertI64/Run_WasmF64SConvertI64 tests.

[wasm] Introduce the TrapIf and TrapUnless operators to generate trap code. Some instructions in WebAssembly trap for some inputs, which means that the execution is terminated and (at least at the moment) a JavaScript exception is thrown. Examples for traps are out-of-bounds memory accesses, or integer divisions by zero. Without the TrapIf and TrapUnless operators trap check in WebAssembly introduces 5 TurboFan nodes (branch, if_true, if_false, trap-reason constant, trap-position constant), in addition to the trap condition itself. Additionally, each WebAssembly function has four TurboFan nodes (merge, effect_phi, 2 phis) whose number of inputs is linear to the number of trap checks in the function. Especially for functions with high numbers of trap checks we observe a significant slowdown in compilation time, down to 0.22 MiB/s in the sqlite benchmark instead of the average of 3 MiB/s in other benchmarks. By introducing a TrapIf common operator only a single node is necessary per trap check, in addition to the trap condition. Also the nodes which are shared between trap checks (merge, effect_phi, 2 phis) would disappear. First measurements suggest a speedup of 30-50% on average. This CL only implements TrapIf and TrapUnless on x64. The implementation is also hidden behind the --wasm-trap-if flag. Please take a special look at how the source position is transfered from the instruction selector to the code generator, and at the context that is used for the runtime call.

[wasm] Introduce the TrapIf and TrapUnless operators to generate trap code. Some instructions in WebAssembly trap for some inputs, which means that the execution is terminated and (at least at the moment) a JavaScript exception is thrown. Examples for traps are out-of-bounds memory accesses, or integer divisions by zero. Without the TrapIf and TrapUnless operators trap check in WebAssembly introduces 5 TurboFan nodes (branch, if_true, if_false, trap-reason constant, trap-position constant), in addition to the trap condition itself. Additionally, each WebAssembly function has four TurboFan nodes (merge, effect_phi, 2 phis) whose number of inputs is linear to the number of trap checks in the function. Especially for functions with high numbers of trap checks we observe a significant slowdown in compilation time, down to 0.22 MiB/s in the sqlite benchmark instead of the average of 3 MiB/s in other benchmarks. By introducing a TrapIf common operator only a single node is necessary per trap check, in addition to the trap condition. Also the nodes which are shared between trap checks (merge, effect_phi, 2 phis) would disappear. First measurements suggest a speedup of 30-50% on average. This CL only implements TrapIf and TrapUnless on x64. The implementation is also hidden behind the --wasm-trap-if flag. Please take a special look at how the source position is transfered from the instruction selector to the code generator, and at the context that is used for the runtime call.

[wasm] Introduce the TrapIf and TrapUnless operators to generate trap code. Some instructions in WebAssembly trap for some inputs, which means that the execution is terminated and (at least at the moment) a JavaScript exception is thrown. Examples for traps are out-of-bounds memory accesses, or integer divisions by zero. Without the TrapIf and TrapUnless operators trap check in WebAssembly introduces 5 TurboFan nodes (branch, if_true, if_false, trap-reason constant, trap-position constant), in addition to the trap condition itself. Additionally, each WebAssembly function has four TurboFan nodes (merge, effect_phi, 2 phis) whose number of inputs is linear to the number of trap checks in the function. Especially for functions with high numbers of trap checks we observe a significant slowdown in compilation time, down to 0.22 MiB/s in the sqlite benchmark instead of the average of 3 MiB/s in other benchmarks. By introducing a TrapIf common operator only a single node is necessary per trap check, in addition to the trap condition. Also the nodes which are shared between trap checks (merge, effect_phi, 2 phis) would disappear. First measurements suggest a speedup of 30-50% on average. This CL only implements TrapIf and TrapUnless on x64. The implementation is also hidden behind the --wasm-trap-if flag. Please take a special look at how the source position is transfered from the instruction selector to the code generator, and at the context that is used for the runtime call.
