Numba Meeting: 2018-11-13

Attendees: Stuart, Stan, Siu, Todd

LLVM 7 status
- problem with common linkage symbol allocation during caching
- TODO:
  - fix SVML with new patch first
  - Look at LLVM master to see if anyone is fiddling with this code
String status
- string PR is in but pending literal/constant refactor PR
- next step optimizations:
  - Single character optimizations
  - faster substring search
Clean up old numba style
- prefer @overload over manual template
- tanh impl mismatch: cpython vs numpy
Cast is not handling refct.

#3490 - ARMv7l np.trace test failing
#3489 - kwarg support in extending API @overload_method broken
#3486 - numba.stencil does not have a “mode” parameter
#3485 - Implement mode “wrap” for numba.stencil
#3483 - cuda.to_device ignore current context
#3482 - Getting PTXAS info from cuda kernel
#3475 Flushing STDOUT in nopython mode
#3474 - LoweringError when passing kwargs to print()
#3472 - List comprehension in jit function will not trigger undefined variable errors

#3491 - Prevent faulthandler installation on armv7l.
- ready to merge
#3488 - Remove dead script.
- ready to merge
#3487 - Raise unsupported for kwargs given to print()
- ready to merge
#3484 - Size Numba logo in docs in px units. Fixes #3313
- ready to merge
#3480 - np.tri, np.tril, np.triu - default optional args
- Very close to ready
- General observation: handling keyword arguments and optional arguments is too hard. Need streamlining and documentation.

3397 - Fix with-objmode warning
- ready to merge
3392 - Launch and attach gdb directly from Numba.
3390 - typeinfer: use unknown_loc object instead of string literal
3385 - conda recipe: whitelist libiomp5.dylib
3382 - CUDA_ERROR_MISALIGNED_ADDRESS Using Multiple Const Arrays
- ready to merge
3162 - Support constant dtype string in nopython mode in functions like numpy.empty.
- Need to resolve #3195
3160 - First attempt at parallel diagnostics
- Stuart will implement Todd's suggestion
3134 - [WIP] Cfunc x86 abi
- Needs re-review
3046 - Pairwise sum implementation.
#2999 - Support LowLevelCallable
#2950 - Fix dispatcher to only consider contiguous-ness.
- ready to merge
