In regards to vectorisation, one of my first targets is the uComplex
unit, which uses a record type consisting of 2 Doubles to hold a complex
number and whose operator procedures are good candidates for the
'vectorcall' calling convention under Win64 (it's a little more flexible
at creating vec
I have a passion for games programming so this one really rings close
for me. The tricky thing is that early SSE and AVX instructions have to
fill and use the entire register - it's only AVX512 that starts to allow
partial filling, so things like packed 3-dimensional vectors are a
little diffi

Your plans are vectorization are an important gain for linear algebra and
games.
Could you detect things like:
var
a, b, c: TVec2;
begin
c := a + b * V2(10, 10);
where th
The other slight difficulty is that because I'm looking at the direct
assembly langauge, I'm not always sure what Pascal code produces said
assembly language. Granted that's because I tend to dump the assembly
files without the -al option, and I only tend to use the -ar option if
there's some
It's probably a good idea, yes. Normally the optimisations I implement
are due to me spotting something in the RTL or compiler disassembly
while optimising something else, so the tests per se are in those
units. Dedicated tests, like my recently added POPCNT tests, are a good
idea even if the

Some people requested a Patreon post as to my plans for 2022 with FPC,
so I was happy to oblige. Plans may change a bit though depending on
what happens in life and also what Florian's own vision is with the
compiler, but this is the gist of it:
