[SAOC 2026] MLIR support Weekly Update #1

[Asadbek]

Hello everyone,

I am Asadbek and I will be working on adding MLIR support in LDC 
compiler as part of SAOC 2026. I wanted to share the first of 
many of the upcoming weekly updates on my progress on adding MLIR 
support to LDC compiler. You can find about the milestones at [1].

During the first week, I have worked on adding new special 
`LDC_inline_mlir` pragma that later let us implement `inlineMLIR` 
akin to `inlineIR` function. That is the first starting point for 
adding MLIR and thanks to my mentor Nicholas Wilson for coming up 
with this idea as it will let us use inlined MLIR code and also 
force us to setup necessary MLIR infrastructure in the compiler 
with smaller but noticeable compiler feature.

I have implemented basic semantic analysis and already started 
(but not yet finished) setting up MLIR build infrastructure for 
LDC compiler.

I went through old D forum threads [2] on adding MLIR support and 
I found good tips that helped me to improve my local compiler 
development setup.

I'll keep posting weekly updates so the community can follow the 
project's progress. Thanks for reading!

Best,
Asadbek
