Hello,
I'm trying to understand how to query information about `Var`s from a
Core plugin. Consider the snippet of haskell:
```
{-# LANGUAGE MagicHash #-}
import GHC.Prim
fib :: Int# -> Int#
fib i = case i of 0# -> i; 1# -> i; _ -> (fib i) +# (fib (i -# 1#))
main :: IO (); main = let x = fib 10
Hello all,
I was interested in building the GHC RTS with GCC's AddressSanitizer and
Ubsan enabled.
What I want to do very specifically is to pass "-fsanitize=address
-fsanitize=undefined" when compiling the RTS.
What's the "correct" way to set this up in the build system? Is there a
configure fl
I'm not sure if this is the right place, but I'm putting this out there at
any rate:
I'd be interested in a deep dive into STG and related shenanigans "within
the compiler", since my understanding is that a decent amount
has changed since the last paper on STG (eval/apply). This is out of an

Ben,
Thank you for the fix :) However, the link appears to be broken?

Elm has a interesting take on this: a collection of all error messages (
https://github.com/elm-lang/error-message-catalog).
I created an empty repo (
https://github.com/bollu/hask-error-messages-catalog) and shot an email to
haskell-cafe asking for examples where GHC generates unintuitive error

Hello all,
Thanks for all the work that's put into GHC :)
I've tried to get into GHC development before, but I was unsuccessful,
mostly because I didn't dedicate enough time to understanding the problem
at hand & exploring the codebase.
I'd like to give it another shot. This time, I think I have
I believe the guarantee at that chunk of code is that void_total of the era
will be >= 0.
I could add an asset at those sections of code if need be.
If not, what is the correct type to be used here? I think size_t is
reasonable as none of them are supposed to be negative in the first place.
