A Brief Introduction to LLVM

[adennyh]

Thanks for this. I felt like learning about LLVM, and this video is nice. You explain it technically enough yet simple enough for non-compiler guy like me to understand.

[Calm_Energy]

I feel like that is such a great way to describe LLVM assembly "strongly typed RISC" yep!

[kartikch]

This explanation is beautifully. Thanks for this.

[omicron]

I haven't seen anyone else mention it so I have to say, your slide animations are killer!

[sepidet]

Thank you so much for this awesome easy-to-understand explanation

[Jan_Jan_]

This was a great explanation - thank you! :)

[abdulqawisaif]

Thanks for this nice and simple talk / lecture :)

[tiberiushoughton]

@Morgan thx so much for this explanation and also for doing an episode on the SE (software engineer) podcast

@Morgan
Thanks! learned something new today.

m*n different compilers for m languages and n targets? nonsense! using a common intermediate level to bring that down to m frontends + n backends has been done forever (also by gcc). The only difference is that gcc connects to its front- and backends at compile-time, so you might need to recompile it with different compiler-flags for different target architectures.

[AnujFalcon]

Without LLVM no. of compilers = m*n; with LLVM no. of compilers = m+n (where m = no. of compilers for source to LLVM and n for LLVM to target machine code)

Thank You Morgan! This is helpful. Do you have any good video pointers to learning llvm dialects?

I think cpython doesn't normally compile python to C and execute? I think it is parsed to some byte code and then run on virtual machine just like Java?

[cepi]

What is the name of this guy? Are there any other his LLVM talks?

[MccZerk]

10:10 "You can compile Python over to C and then C to machine code", this is not true. The compiler is written in C, Python is compiled to bytecode.

@morgan: Is the optimization 2 * x - x = x really valid? considering 2 * x might overflow.

@Morgan Wide
Hi Morgan, can you suggest me some blog where i can learn more about llvm.
I even have a doubt, how can we generate a java bytecode using llvm.

[Sina-xwxp]

one again, immutable variable is not a variable it is a constant :)

[dialecticalmonist]

"LLVM is not an acronym".

Um... ok, great, but could you perhaps say SOMETHING more informative about the name origin?

There is much wrong with this presentation. Compilers didn't "used to be monolithic", you are talking about GCC, which didn't have an external intermediate format. Intermediate formats, and modular compilers go back to the 1950's. Second, you don't need a whole new compiler per language. GCC is sufficiently modular to support multiple languages, and this is actually very common.
