Fantastic, welcome.

Appreciated.

Yes, it's really there to help people to do just that.

Ok, i thought about this a bit, and the most immediate useful thing to do
is quite simple, we need a new table on the wiki that shows the Khronos
OpenCL functions vs the proposed Transcendentals and Trig functions.

Columns with the FP32 name FP16 name native name fast name if one exists.

cos | half_cos | native_cos | fast_cos

Most of the fast column would be empty.

Use the exact function names from the 1op and 2op table, as the 1st column.

2nd column is the FP32 OpenCL name.
3rd is the "half_ name" if it exists
4th is the "native_ name" if it exists
5th is the "fast" name if it exists.

https://libre-riscv.org/ztrans_proposal/

Page is here, it is backed by git so you cannot "lose" anything.

Link to OpenCL table on that page.

Ignore anything NOT in the 1op or 2op table such as round, erfc, fmax,
floor and so on. JUST the transcendentals exp pow log and trigs cos sin
sinpi atan etc.

This is just a really quick nontechnical but also really important task
right now which needs doing, we can talk and plan something else over time
ok?

Really appreciate your help Michael.

L.
