Hi,
IIRC you can already use hscFrontendHook in the DynFlags hooks to retrieve
TcGblEnv, and with a little bit of work, also HsParsedModule.

Hi,
IIRC those packages can be "reinstalled", just build & register into a
fresh package database and add it to the pkgdb stack, ghc can shadow
the ones in the global pkgdb.

I notice there's an "--enable-distro-toolchain" flag, does it work
with building a bindist? Thank you.

Hi all, is it possible for a 64-bit ghc to emit 32-bit code, if I supply a
custom ghcPrimIface via Hooks and also modify the platform flags in
DynFlags? The module does not import Prelude and has no dependencies other
than GHC.Prim.

Hi Simon,
If the build environment is managed by an MSYS2 installation, then the
MinGW64 shell startup script automatically sets up "MSYSTEM" for you. It
can be launched like "C:\msys64\msys2_shell.cmd -mingw64 -mintty".

Compiling GHC on a blockchain may not be economical, but running
GHC-compiled programs on a blockchain is definitely a great idea! I've even
come up with a paper title: A Secure Decentralized Transactional

Hi all,
Is the "cml_cont" field of the CmmCall variant is really used in practice?
I traversed the output of raw Cmm produced by ghc compiling the whole base
package, but the value of cml_cont is always Nothing.

Indeed, the boot.sh script is likely what you are looking for. To
compile `base` and retrieve Core for it, you just need to set up an
empty package database, use the Setup.hs script in base to compile it,
and load your plugin via "--ghc-option=.." provided to `Setup
configure`.

Hi,
Joachim Breitner's veggies(https://github.com/nomeata/veggies) project is a
good example of using a vanilla ghc installation to compile standard
libraries like base.

This looks suspicious. I'm curious if this is intended behavior of ghc.

Hi all,
When an MVar# primop blocks, it jumps to a function in
HeapStackCheck.cmm which pushes a RET_SMALL stack frame before
returning to the scheduler (e.g. the takeMVar# primop jumps to
stg_block_takemvar for stack adjustment). But these functions directly
bump Sp without checking for possible
How about using `hscCompileCoreExprHook` to intercept the `CoreExpr`
from the ghci pipeline? There exist GHC API to evaluate a String to a
ForeignHValue iirc; we are not interested in the final ForeignHValue
in this case, we just want the CoreExpr, and the logic of generating
and linking BCO can
Hi Matthew,
It's possible to use Data.Compact.Serialize to write a compact to a
file or read it back. Directly serializing via ByteStrings has also
been discussed before, see link below. Hope this helps!
