This CL completes the implementation of DataView prototype methods in TurboFan, by implementing the Uint8, Int8, Uint16, Int16, Uint32, Int32, Float32 and Float64 setters. DataView performance is now ahead of the equivalent TypedArray wrapper, and is now expected to at least match TypedArray performance in the general case as well. This CL also adds a test file in the compiler directory, to make sure that the setters actually behave correctly.

This script averages numbers output from another script. It is useful to average over a benchmark that outputs one or more results of the form <key> <number> <unit> key and unit are optional. For example, if $ bch --allow-natives-syntax toNumber.js outputs Number('undefined'): 155763 Kps (+'undefined'): 193050 Kps parseFloat('undefined'): 23736 Kps then $ avg.py 10 bch --allow-natives-syntax toNumber.js will output [10/10] (+'undefined') : avg 192,240.40 stddev 6,486.24 (185,529.00 - 206,186.00) Kps [10/10] Number('undefined') : avg 156,990.10 stddev 16,327.56 (144,718.00 - 202,840.00) Kps [10/10] parseFloat('undefined'): avg 22,885.80 stddev 1,941.80 ( 17,584.00 - 24,266.00) Kps Change-Id: I237706da8ade1b152e04084e0189007460d359c5 Reviewed-on: https://chromium-review.googlesource.com/1128747 Commit-Queue: Sigurd Schneider <sigurds@chromium.org> Reviewed-by:Georg Neis <neis@chromium.org> Cr-Commit-Position: refs/heads/master@{#54330}

Leszek Swirski authored
When live edit patches a script, it distinguishes between 'changed' and 'unchanged' functions, and unchanged functions have their position and source script patched to the new script instead of being replaced by a new SFI. However, if a 'changed' function has an inner 'unchanged' function, it also holds a pointer to the inner function in its bytecode constant pool. This constant pool entry was not being updated for changed functions (it was for unchanged), and therefore the outer changed function would compile the redundant new function instead of the old, patched, unchanged function. This patch fixes this by patching 'changed' functions' bytecode constant pools. This is done by swapping the script and script function list position of the old new and old 'unchanged' function, rather than just setting the script (and position) on the old one, and using the new function (now pointing at the old script) to read off the old function literal id. This could also be done by reading the function_literal_id off the new function, but we are soon removing that field anyway.

Sigurd Schneider authored
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.

Add new types for function data for SharedFunctionInfo, for uncompiled functions. UncompiledData holds start/end positions, allowing us to remove these fields from SFI. Uncompiled functions with pre-parsed scope data now hold an UncompiledDataWithScope that has a pointer to PreParsedScopeData -- this allows us to also remove the start/end pos from PreParsedScopeData.

Specifically the common bug like new Promise((res, rej) => { res(1); throw new Error("something") }); where the error is silently swallowed by the Promise constructor without the user ever noticing can be caught via this hook.

Instead of creating a separate code object per exported function, we can share the code per signature, and load the function index from the {WasmExportedFunction} object which is being passed as an argument anyway. This greatly reduces instantiation time for modules with a lot of exports. As a next step, we could even share the code across instances, or (with more work) across isolates.

This is a clean-up to completely remove the Heap accessors for roots accessible via ReadOnlyRoots. Where previously ReadOnlyRoots called the Heap accessor, now it accesses the roots array directly using the root index (since ReadOnlyRoots is a friend of Heap).

RegExp builtins were the first to be ported to CSA roughly two years ago. Back then, we weren't really aware of issues surrounding code size and CSA inlining, and thus some of these builtins were bigger than they should be. This CL adds a few new helper builtins and removes inlined calls to SubString, RegExpExecInternal, and StringAdd. It significantly reduces the size of affected builtins. Minor performance regressions due to call overhead are expected.
