   9 - Learning SVP64 from Luke, setvl (Horizontal-First), svindex.
  10 - Luke suggested to look at Chacha20 example for Vertical-First
  11 (but not required).
  12 - Look at Luke's examples on Poly1305 bugreport

  33 - Took Monday off as a break.
  34
  35 - Luke and I in conversation with Michiel to finalise the ongoing grant MoU.
  36 *(The MoU was signed the following week.)*
  37
  38 - Raised a bug report relating to ISACaller not taking a sv.bc branch in
  39 Vertical-First mode,
  40 [bug #1210](https://bugs.libre-soc.org/show_bug.cgi?id=1210).
  41   - After checking with Python pdb, it was spotted that ISACaller correctly
  42 computes NIA (Next Instruction Address) based on branch condition,
  43 but this correct NIA is overwritten by extraneous NIA update (which defaults
  44 to to the next instruction address).
  45   - After Jacob pushed a fix in a branch, I ran the test and the sv.bc branch
  46 was taken correctly.
  47
  48 - Continued to work on Libre-SOC documentation included in [[HDL_workflow]]
  49 and [[HDL_workflow/libresoc_bug_process]]. See
  50 [bug #1126](https://bugs.libre-soc.org/show_bug.cgi?id=1126) for updates.

  52 # Luke
  53
  54 * cookbook example pospopcount with shriya
  55 * load/store shifted ls004
  56 * cookbook example maxloc, but stalled due to needing
  57   ddffirst
  58 * Working on Maxloc assembler example, run into same issue as Jacob,
  59 where scalar src/dest but need loop to continue.
  60 * So this feature is pretty important and needs to be added
  61 to the SVP64 spec
  62
  63 # Shriya
  64
  65 * Load/store-shifted corrections, jacob to review (thank you)
  66 * maxloc research
  67 * pospopcount images
