I think we need to make it a point to support Mir in dmd. --

Required features for Level 3:
1. https://issues.dlang.org/show_bug.cgi?id=16489
2. https://issues.dlang.org/show_bug.cgi?id=16488
3. AVX & AVX2 floating point vector arithmetic
4. Generic unaligned load/store like (like LDC loadUnaligned and
storeUnaligned)
5. Generic routine to pack and unpack real and imaginary parts.
For usage example, see
https://github.com/libmir/mir/blob/master/source/mir/glas/internal/copy.d#L699
Level 1 and Level 2 requires additional features like automatic
loop unrolling with associative math.
In the same time, I don't think that DMD support is important for
D and Mir. The following features are _much_ more important:
1. Lightweight `nothrow @nogc` threads, implemented using
`struct`s
2. Lightweight `nothrow @nogc` mutexes and barriers, implemented
using `struct`s
3. Low level and detailed CPUID with proper cache sizes (already
implemented for x86 here: https://github.com/libmir/cpuid)
4. Ability to use some phobos modules like std.traits, std.meta,
std.complex.Complex (without ^^), std.experimental.ndslice,
std.allocator without current (old) DRuntime, "module info" and
other harmful for "better C" feature.
5. LDC compiler support for ARM, MIPS, MIPS64, Alpha
6. LDC SDK, which can work out of the box (including windows). It
is required for D to be popular for scientists
This features are good not only for Mir, but for the D future. I
think that D can not be more popular then Go and Rust. This is
reality and I don't think that it is bad. Why? Because D can be a
backend language fo Go and Rust. It can replace C/C++/Fortran in
following fields:
1. Low level high performance computation libraries like BLAS,
Eigen, Intel MKL, MAGMA, scaLAPACK, and many others
2. Close to metal drivers
3. OS kernels
4. Aerospace and related software
5. The Khronos Group software (!)
We have not new concurrents in this fields, but C/C++/Fortran.
Our problem is that we trying to be more hight level language
than the IT industry needs. Lets forget about Go and Rust
"concurrents" and remember about the initial D goal, which is
more actual then ever: replace C/C++ in the IT industry.
Best regards,
Ilya
