Okay, you've done a C++ compiler. Nobody uses that compiler in

For about a decade, dmc was outcompeting the efforts of big
companies in features, compile speed, code optimization, AND
stability.
Sure, it has fallen behind now, but only because Walter sat
down for 15 years so they could catch up.... (time he used to
get streets ahead by creating this thing called 'Mars', which
again the big guys are trying to catch up to).
I'm happy with the codegen the way it is, it is good enough for
me, but let's not make mountains out of hills.
I'm writing a 3D engine in D.
There's many, many of math. In my benchmarks when it's compiled
with DMD there's ~100 fps and with LDC fps raises to ~500. LDC
vectorizes all operations with matrix, inlines, etc.
If it's good to you, it's not so for others.
Quality of codegen is not only performance, but also how many
battery apps drain on portables.
