The C++ code uses the A instruction key for return address signing, which is the default for Clang and GCC when the -mbranch-protection option is used (although this can be configured to use the B key). Using the B key for JS means that it's not possible to use an A key signing gadget to replace a return address signed with the B key and vice-versa. This should offer a degree of separation from the C++ side.

There are cases where we push FP and LR to the stack even though we have already created a frame and already stored them. Avoid doing this, by cleaning up the caller- and callee-saved register lists, and passing a LinkRegisterStatus argument to TruncateDoubleToI.

This was done mostly automatically using this command: ag -l '\btypedef\b' src test | xargs -L1 \ perl -i -p0e 's/typedef ([^*;{}]+) (\w+);/using \2 = \1;/sg' Patchset 2 then adds some manual changes for typedefs for pointer types, where the regular expression did not match.

For each intrinsic/runtime function we define in runtime.h, an inline version is automatically declared. We only ever use 24 of the inline functions. Even though we don't call the other ones, macro magic means they still take up space by existing in various arrays and tables like kIntrinsicFunctions. They also create code in switch statements. Some drive-by cleanups: - Remove the switch in NameForRuntimeId() and just use the table of runtime functions to lookup the name directly. - Remove tests for IsFunction, ClassOf and StringAdd intrinsics as they are the last users of the inline versions of these. - Remove the MaxSmi inline version as it is only used in tests. Saves 64 KiB binary size.

This CL uses pc-relative jumps and calls (B/BL) for calls from embedded builtins to embedded builtins. To make this work, the code range size is limited to 32MB on arm during mksnapshot, which ensures that all builtin to builtin offsets for jumps/calls fit into the B/BL immediate. At code generation time, we put a placeholder into the instruction offset which we resolve to the right code object when the code is copied to the heap. We use a new relocation mode RELATIVE_CODE_TARGET for these relative jumps. The relocation mode RELATIVE_CODE_TARGET should never appear after generating the snapshot. We modify the target_address/set_target_address methods of RelocInfo such that they return the absolute target addresses for pc-relative B/BL instructions. This ensures that the GC can treat RELATIVE_CODE_TARGET in the same way as code targets. This, however, only matters during snapshot creation time, and production code never contains RELATIVE_CODE_TARGET relocations.

We had a kRootRegisterBias on x64 before. This CL ports the feature to all other platforms as well. The root register bias is helpful to adjust the value of the root register, which allows to better utilize signed immediate offset constants in load instructions. We currently use a separate add instruction to add kRootRegisterBias in the code that initializes the root register. This could be improved by adding a custom relocation mode ensuring that instead of the root address, the root address plus the bias is inserted (and in this way the add instruction can be omitted).

Add support for CSDB, equivalent to HINT #20, in the system instruction space. Additionally, relax the "unallocated" identification of hint instructions that we don't support, such that they'll now disassemble as "unimplemented (System)" rather than "unallocated".

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.
