Since the turbo_decompression_elimination flag is removed, there are several methods in machine-type.h that get simplified, e.g TypeCompressedTaggedPointer() can be replaced by just "TaggedPointer()". Also Removing the creation of Change to/from Compressed nodes. Removing these Change nodes' logic is left to a follow-up CL.

This is a reland of 54379af9. Instead of removing the limit completely, this limits to 128 parallel tasks now. This avoids some special handling for the previous default value of -1.

Lack of size information can cause debugging and observability tools to misbehave or to fail. We can see the size for all builtins is zero with objdump: $ objdump -t d8 | grep Builtins_ArgumentsAdaptorTrampoline 0000000001084a00 l F .text 0000000000000000 Builtins_ArgumentsAdaptorTrampoline ^ Size is zero Tools like bpftrace rely on the function size to guarantee a tracepoint is added within function boundaries. Without size information, those tools can't guarantee a tracepoint will be added safely. Add .size directive for each builtin function, as described in https://sourceware.org/binutils/docs-2.24/as/Size.html#Size, to fix this issue. We can see with objdump that the size is properly set: $ objdump -t d8 | grep Builtins_ArgumentsAdaptorTrampoline 00000000010bf820 l F .text 0000000000000140 Builtins_ArgumentsAdaptorTrampoline R=bmeurer@chromium.org, hpayer@chromium.org, verwaest@chromium.org, yangguo@chromium.org Change-Id: I4cd2b0a12b629498dd9d7465cc1002dda37028c7 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/1898807 Commit-Queue: Jakob Gruber <jgruber@chromium.org> Reviewed-by:Benedikt Meurer <bmeurer@chromium.org> Reviewed-by:

Introduce new operator LoadTransform that holds a LoadTransformInfo param, which describes the kind of load (normal, unaligned, protected), and a transformation (splat or extend, signed or unsigned). We have a new method that a full decoder needs to implement, LoadTransform, which resuses the existing LoadType we have, but also takes a LoadTransform, to distinguish between splats and extends at the decoder level. This implements 4 out of the 10 suggested load splat/extend operations (to keep the cl smaller), and is also missing interpreter support (will be added in the future).
