This reverts commit313d4844d9. Reason for revert: https://ci.chromium.org/p/v8/builders/ci/V8%20Linux%20gcc/6354 Original change's description: > Reland^3 "[parser] Introduce UnoptimizedCompileFlags" > > This is a reland of0a59e0cb08> which was a reland of146f5375da> which was a reland ofd91679bf3a> > Initializes the BackgroundCompileTasks's language_mode in the > constructor (previously only initialized after successful parse) in case > the parse failed. We still need to reset it after parse in case the > language mode changed (because we encountered "use strict"). > > Original change's description: > > [parser] Introduce UnoptimizedCompileFlags > > > > UnoptimizedCompileFlags defines the input flags shared between parse and > > compile (currently parse-only). It is set initially with some values, and > > is immutable after being passed to ParseInfo (ParseInfo still has getters > > for the fields, but no setters). > > > > Since a few of the existing flags were output flags, ParseInfo now has a > > new output_flags field, which will eventually migrate to a ParseOutputs > > structure. > > > > Bug: v8:10314 > > Change-Id: If3890a5fad883bca80a97bf9dfe44d91797dc286 > > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2096580 > > Commit-Queue: Leszek Swirski <leszeks@chromium.org> > > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > > Reviewed-by: Simon Zünd <szuend@chromium.org> > > Reviewed-by: Ross McIlroy <rmcilroy@chromium.org> > > Cr-Commit-Position: refs/heads/master@{#66782} > > TBR=ulan@chromium.org,szuend@chromium.org,rmcilroy@chromium.org > > Bug: v8:10314 > Change-Id: Ieee0bbfade4fe0b56de03bff47a7364959608d6a > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2157367 > Reviewed-by: Leszek Swirski <leszeks@chromium.org> > Commit-Queue: Leszek Swirski <leszeks@chromium.org> > Cr-Commit-Position: refs/heads/master@{#67265} TBR=leszeks@chromium.org Change-Id: I90ac035caa76d4c4baf5ce207247d1ce5169fb2f No-Presubmit: true No-Tree-Checks: true No-Try: true Bug: v8:10314 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2157370 Reviewed-by: Sathya Gunasekaran <gsathya@chromium.org> Commit-Queue: Sathya Gunasekaran <gsathya@chromium.org> Cr-Commit-Position: refs/heads/master@{#67266}
