LGTM but can you bump the patchlevel in deps/v8/include/v8-version.h and request backports to the 5.2 and 5.3 branches? |
Contributor

LGTM once patchlevel is updated. |

Thanks for the reviews. I've updated the patch level. Will also request backports to 5.2/5.3 as well. |

Not sure how earlier builds were launched but here are ones that seem to be working: https://ci.nodejs.org/job/node-test-commit-v8-linux/209/ |

CI runs green. |

Going to land now. |

Unfortunately it does not seem to apply. Can you rebase. |

@mhdawson Conflict in v8-version.h, right? Just reset to HEAD and bump the patchlevel yourself. |
Original commit message:
S390:Update inline asm constraint in test-platform
The GetStackPointer() routine in test-platform uses an inline
assembly code to store the current stack pointer value into a static
variable sp_addr. The existing asm code for S390 uses an ST/STG
instruction, with the memory operand associated with the general ('=g')
constraint to sp_addr.
On GCC 4.8.5, the GCC compiler got confused and treated sp_addr as
an integer operand instead of memory operand, resulting in a store
being emitted that writes to an invalid meory location.
Given the specific store instructions being inlined here, we should
restict the sp_addr operand to explicitly be a memory operand using '=m'
instead of '=g'.

Does this need to be backported to v6.x? |
Contributor

@evanlucas No. This fix is S390 specific; v6.x is still using V8 5.0, which doesn't have full S390 support. Unless V8 5.1 lands there.... |

@joransiu Could you do the backport request ? Can you please post a link to the related V8 bug here ? |

Here's the issue tracking the V8 backports (to 5.2 / 5.3). https://bugs.chromium.org/p/v8/issues/detail?id=5225 |
