Since JS arguments are always reversed now (https://crrev.com/c/2466116), the logic for skipping the arguments adapter is dead. Hence this CL removes the dead enum value and all code handling it.

Migrate wrapper compilation from the tasks API to the job API. This avoids querying the platform for the number of available threads, and makes the code much more idiomatic.

Replace the "PublishCompilationResults" event by "AddCompiledCode" and "PublishCode". The former will be parallel, while the latter will not be. This was a bit misleading before, since in the "PublishCompilationResults" event we didn't always publish.

The problem was that a raw regexp value was handlified to account for gc, but then afterwards we used the initial regexp value again instead of the handle. This resulted in memory violations if the gc decided to move the regexp object.

Preparing for tail call is usually done by emitting the gap moves and then moving the stack pointer to its new position. An optimization consists in moving the stack pointer first and transforming some of the moves into pushes. In the attached case it looks like this (arm): 138 add sp, sp, #40 13c str r6, [sp, #-4]! 140 str r6, [sp, #-4]! 144 str r6, [sp, #-4]! 148 str r6, [sp, #-4]! 14c str r6, [sp, #-4]! ... 160 vldr d1, [sp - 4*3] The last line is a gap reload, but because the stack pointer was already moved, the slot is now below the stack pointer. This is invalid and triggers this DCHECK: Fatal error in ../../v8/src/codegen/arm/assembler-arm.cc, line 402 Debug check failed: 0 <= offset (0 vs. -12). A comment already explains that we skip the optimization if the gap contains stack moves to prevent this, but the code only checks for non-FP slots. This is fixed by replacing "source.IsStackSlot()" with "source.IsAnyStackSlot()": 108 vldr d1, [sp + 4*2] ... 118 str r0, [sp, #+36] 11c str r0, [sp, #+32] 120 str r0, [sp, #+28] 124 str r0, [sp, #+24] 128 str r0, [sp, #+20] ... 134 add sp, sp, #20 R=jgruber@chromium.org Bug: chromium:1137608 Change-Id: If2b85dde49bf31a6bd3f5e0255407f9390727f9d Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2474784Reviewed-by:

This fixes a bug that made a test fail in mjsunit/wasm/return-call.js (the CFI bot does not run the tests with --variants=extra, hence why it didn't catch it). It also introduces --sim-abort-on-bad-auth, a debug flag for the arm64 simulator that stops a program as soon as an authentication error appears, to make debugging easier.

While the overall goal of this commit is to change deoptimization entries into builtins, there are multiple related things happening: - Deoptimization entries, formerly stubs (i.e. Code objects generated at runtime, guaranteed to be immovable), have been converted into builtins. The major restriction is that we now need to preserve the kRootRegister, which was formerly used on most architectures to pass the deoptimization id. The solution differs based on platform. - Renamed DEOPT_ENTRIES_OR_FOR_TESTING code kind to FOR_TESTING. - Removed heap/ support for immovable Code generation. - Removed the DeserializerData class (no longer needed). - arm64: to preserve 4-byte deopt exits, introduced a new optimization in which the final jump to the deoptimization entry is generated once per Code object, and deopt exits can continue to emit a near-call. - arm,ia32,x64: change to fixed-size deopt exits. This reduces exit sizes by 4/8, 5, and 5 bytes, respectively. On arm the deopt exit size is reduced from 12 (or 16) bytes to 8 bytes by using the same strategy as on arm64 (recalc deopt id from return address). Before: e300a002 movw r10, <id> e59fc024 ldr ip, [pc, <entry offset>] e12fff3c blx ip After: e59acb35 ldr ip, [r10, <entry offset>] e12fff3c blx ip On arm64 the deopt exit size remains 4 bytes (or 8 bytes in same cases with CFI). Additionally, up to 4 builtin jumps are emitted per Code object (max 32 bytes added overhead per Code object). Before: 9401cdae bl <entry offset> After: # eager deoptimization entry jump. f95b1f50 ldr x16, [x26, <eager entry offset>] d61f0200 br x16 # lazy deoptimization entry jump. f95b2b50 ldr x16, [x26, <lazy entry offset>] d61f0200 br x16 # the deopt exit. 97fffffc bl <eager deoptimization entry jump offset> On ia32 the deopt exit size is reduced from 10 to 5 bytes.

This changes remoteObjectId format from "{injectedScriptId:123,id:456}" to "<isolateId>.<contextId>.<id>". Prepending isolateId fixes the problem that remote object ids clash between processes. This is especially troubling during cross-process navigation in Chromium, see bug. We also stop producing and parsing unnecessary json for object ids. Drive-by: fixed some tests dumping object ids. Most tests avoid dumping unstable values like ids, but there were few that still did.

LocalHeap can be used on main thread, however allocation might cause a GC which works differently on the main thread than on a background thread. Support collection on main thread by directly performing the GC instead of requesting the GC as done on background threads. To allow for differentiation between main and background threads, LocalHeap/LocalIsolate now require an additional argument.
