      [gn] Allow building a snapshot with unwinding information. · 73ab0f4b
      pierre.langlois authored
      Add a new "v8_perf_prof_unwinding_info" option to gn that translates to building
      the snapshot with "--perf-prof-unwinding-info". It allows unwinding TF generated
      code from the snapshot.
      
      Additionally, add a warning if one uses the option along with a snapshot which
      was not build with unwinding information.
      
      Running tests in this configuration revealed an issue in the checks performed
      when accessing the stub cache. We would assume that the `Code::Flags` bitfield
      only contains the `Kind` and `ExtraICState` fields, when there is also a
      `HasUnwindingInfo` field which can now be set for stubs.

      [ignition] Change --trace-ignition to a runtime flag · 4becbe34
      Leszek Swirski authored
      Generate the code (extra runtime calls) for --trace-ignition support at
      compile time, based on a #define (similar to TRACE_MAPS). Then check for
      --trace-ignition at run-time when deciding whether to actually print
      anything. This should make --trace-ignition less painful to use.
      
      Note that --trace-igition is disabled by default, even on debug builds.
      It has to be enabled with the gn arg "v8_enable_trace_ignition=true"
      
      As a drive-by, TRACE_MAPS is renamed to V8_TRACE_MAPS, for consistency,
      and SFI unique index (needed both by --trace-ignition and --trace-maps)
      is cleaned up to be behind another #define.

      Revert of [snapshot] Move builtins generation into mksnapshot (patchset #8 id:160001 of https://codereview.chromium.org/2760233005/ )
      
      Reason for revert:
      I think that this CL breaks chromium compilation on windows with clang (). All other CLs in the list looks trivial and don't change test/unittest/BUILD.gn.
