Prototype these 6 instructions on arm64: - f64x2.convert_low_i32x4_s - f64x2.convert_low_i32x4_u - i32x4.trunc_sat_f64x2_s_zero - i32x4.trunc_sat_f64x2_u_zero - f32x4.demote_f64x2_zero - f64x2.promote_low_f32x4 Drive-by fix: - f64x2.promote_low_f32x4 accesses out of bounds for the global, the result only has 2 doubles - fcvtn in simulator needs to clear top bits of the Q reg Bug: v8:11265 Change-Id: Icfb3338942f0d0374448fdcfef3847a6e3ce8ff6 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2644066Reviewed-by: Deepti Gandluri <gdeepti@chromium.org> Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> Commit-Queue: Zhi An Ng <zhin@chromium.org> Cr-Commit-Position: refs/heads/master@{#72373}

This includes the instruction opcode, its use in TF, its support in the simulator and the detection of the associated CPU feature. The instruction can be tested in the simulator with the new --sim-arm64-optional-features flag.

This should have no effect unless the embedder uses an old version of the standard library with missing overloads of <math.h> functions, which causes such functions to perform implicit conversion to double. In such cases, the CL removes the implicit conversion.

The platform-specific simulators are only included on the respective hardware, so no need to guard against other platforms. Also, unify where the USE_SIMULATOR macro is evaluated. Make it cover the whole implementation file. Also, make sure to include the respective header file first, as suggested by the style guide, and fix up includes in general.

This patch normalizes the casing of hexadecimal digits in escape sequences of the form `\xNN` and integer literals of the form `0xNNNN`. Previously, the V8 code base used an inconsistent mixture of uppercase and lowercase. Google’s C++ style guide uses uppercase in its examples: https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters Moreover, uppercase letters more clearly stand out from the lowercase `x` (or `u`) characters at the start, as well as lowercase letters elsewhere in strings.

This reverts commit c5aad5f2 The CL was reverted due to missing Chromium dependencies. This commit removes the simulator trace-based tests, and the associated header file dependencies, previously pulled in by DEPS. The NEON support now has only hand-written tests, in test-assembler-arm64.cc. The remaining tests can be added in a later patch.
