The RNG state is initialized with random_seed parameter that usually has lots of zeros. Each random generation iteration shuffles bits with xor operation over the state. It takes a while before the state is populated with enough 1s and starts generating uniformly distributed numbers. The patch warms up the state with 32 iterations when --random_seed is used.

Previously, bootstrapper.cc contained a mixture of approaches: - NewStringFromAsciiChecked("foo"): 40 matches - NewStringFromStaticChars("foo"): 4 matches - InternalizeUtf8String("foo"): 55 matches The most common use case for any of these in the bootstrapper is to represent property names. For those, we eventually need internalized strings anyhow. E.g. NewStringFromAscii causes an InternalizeString call later, possibly creating a copy or ThinString. This patch uses InternalizeUtf8String where it makes sense to do so. https://chromium-review.googlesource.com/c/v8/v8/+/1253603/1/src/bootstrapper.cc#2098 Bug: v8:8238 Change-Id: I124607988b75449d7f78d5933657c35b532bd1c9 Reviewed-on: https://chromium-review.googlesource.com/c/1255727 Commit-Queue: Mathias Bynens <mathias@chromium.org> Reviewed-by:Toon Verwaest <verwaest@chromium.org> Cr-Commit-Position: refs/heads/master@{#56417}

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.

After rewriting a rewritable assignment expression we possibly add the resulting do-expression in two places: the rewritten expression and the parent block. That would observably generate duplicate code. Luckily this can't happen since the only recursive paths that would call this function again change the context to ASSIGNMENT_ELEMENT from ASSIGNMENT. Hence simply DCHECK_NULL(block_) and reset it to nullptr at the end. Change-Id: I17b84dedcd7daf800d9ccb90e3dd975e84b12717 Reviewed-on: https://chromium-review.googlesource.com/c/1264282Reviewed-by:

var declarations that walk through with scopes are special in that the variable will always end up in the outer declaration scope, but the initializer for the var will possibly target the with scope. Hence we can't simply use the resolved variable proxy from the declaration for the initialization. However, if we know that the var declaration lives in the scope where it will be declared (the common case), there can't be a with scope in between. Hence we are free to reuse the proxy.

When parsing an identifier as an expression we'll immediately create an unresolved VariableProxy in the parsing scope. If this variable ends up becoming a declaration, e.g., due to arrow function parameter, we'll move it into the function scope for that arrow function. Then to actually create the declarations we rewrite the "pattern". When we declare the variable, the proxy is automatically resolved to the variable we create from it. That means it can't be in the unresolved list anymore. We tried to remove the unresolved variable. Unfortunately, if there was a sloppy eval in a parameter context, there's an additional var-block scope created for the parameter. Rewriting happens in *that* scope. Hence we didn't always manage to remove the unresolved variable. I suppose as a fix an additional variable proxy was introduced; since otherwise the implicit resolution upon declaration would trigger a dcheck in scope resolution later. This CL removes the initial variable proxy from the correct scope, so it can be reused for the declaration.

- Get rid of an unnecessary call to uloc_canonicalize in js-locale. - Do not use regex, but rely on ICU for the structrural validity check with Chrome's ICU or ICU 63 or newer. Otherwise, continue to use regex. This became possible thanks to a couple of bug fixes in ICU ToT that were cherry-picked for Chromium's ICU. Not yet done is to change js-locale to use CanonicalizeLocale(). That will make a few more tests pass.
