      [arm] Add missing RELATIVE_CODE_TARGET iteration · b766299d
      Jakob Gruber authored
      Code object iteration was missing logic for RELATIVE_CODE_TARGET
      reloc entries. Garbage collection could thus miss objects that were
      referenced only as targets of pc-relative calls or jumps.
      
      RELATIVE_CODE_TARGETs are only used on arm, mips, and s390 and only
      at mksnapshot-time.
      
      This exposed another issue in that the interpreter entry trampoline
      copy we generate for profiling *did* contain relative calls in
      runtime-accessible code. This is a problem, since code space on arm is,
      by default, too large to be fully addressable through pc-relative
      calls. This CL thus also disables the related
      FLAG_interpreted_frames_native_stack feature on arm.
      
      Drive-by: Ensure the builtins constants table does not contain Code
      objects.

      [Builtins] Infrastructure for source positions in stubs/builtins · df071e94
      Mike Stanton authored
      Now, the CodeAssembler can annotate Nodes with SourcePositions.
      SourcePositions themselves get a new mode "external," in which
      they get a file_id, line and column. The file_id is currently
      maintained in the isolate, mapping to strings for filenames.
      
      Additionally, inlining information is ignored at this point,
      but in the long run I'd like to recognize calls to different
      CSA functions as manual inlinings.
      
      At this point, if you want to see the results in tools like GDB,
      you'll need to build without clang, and use the GCC toolchain.
      GN flag is_clang=false will do the trick.
