PowerPC: Initial SFrame support for 64-bit PowerPC ELF ABI

Reviewer Indu Bhagat needs more time to test patches related to PowerPC SFrame support.

Indu Bhagat apologizes for the delay in reviewing Abhay Kandpal’s patches for 64-bit PowerPC ELF ABI SFrame support. Work commitments have prevented Indu from running the necessary stacktracer tests. Indu expects to have more time in a few weeks and asks Abhay if he would prefer a rebased v3 instead of waiting for review of v2.

In the Thread 2 participants
  1. Indu Bhagat reviewer

    Requests more time to test the SFrame support patches due to work commitments, and asks if a rebased v3 would be preferred.

    “Apologies I have not been able to find time in the last few weeks, due to some work related commitments. I expect to find a better balance in a few weeks. At this time, I wanted to run some stacktracer tests on ppc using your patches, but havent been able to get to the task.”
  2. Abhay Kandpal proposer

    Previously pinged Indu for a review of v2 of the SFrame support patches and offered to post a rebased v3 if that would be easier.

In Details

This is a follow-up on a review of patches intended to add support for SFrame unwind information to the 64-bit PowerPC ELF ABI. The reviewer, Indu Bhagat, is currently unable to perform the necessary stacktracer tests due to external work commitments and is seeking to manage the review timeline, potentially by accepting a rebased version of the patches.
