Hi all,
Zubin is preparing the 9.4.6 release so we expect to release it within
the next two weeks.
The focus of the release ot back-port the quite large number of fixes
which are marked for backport to 9.4.
The ticket which tracks bumping the bootstrap compiler to 9.4 is
https://gitlab.haskell.org/ghc/ghc/-/issues/23195
We should bump all the images and update the configure check *before*
merging changes which require a newer bootstrap compiler.

I don't think you need to engineer this requirement. GHC should work

Hi Facundo
Some pointers...
1. Only put things in the EPS if they are not going to change
throughout the whole compilation
2. Treat everything which can change as a home package
2a. I suppose you have performed your own dependency analysis, so
build your own `ModGraph` and start looking from

Hi Gergo,
Source Notes are what you are looking for. Currently the only way to
enable them is to either use `-g` or `-finfo-table-map`. The result
will be core which contains nodes which attempt to describe where the
core expression came from, it's not perfect though!
See Section 5.4 -
Looks good Ben.
Would it be good to add a target to hadrian which builds just the
right dependencies for this to work? and then deals with setting

Hi Norman,
I think you are overcomplicating things quite a bit.
1. Build a HEAD (9.3) compiler
2. Setup a normal cabal project to depend on the `ghc` library
3. Use the cabal -w option to point to your HEAD compiler to build the
project (`cabal build -w /path/to/head`)
That will work reliably

My patch adding `-finfo-table-map` and `-fdistinct-constructor-tables`
is ready to review and should be included in 9.2.
https://gitlab.haskell.org/ghc/ghc/-/merge_requests/3469
There are also a one outstanding patches related to ghc-debug.
Hi Andrew,
I updated the README for ghc-debug last week but forget to send this mail!

Cheers,

Hi,
My patch 3358 needs to get merged before the 8.12 fork.
When I finished it (in May), it passed CI and after this point I
lacked time to work on it further. Now I have asked 4 times for this
patch to get merged and it is still open.
The GHC proposal for this patch already took an
tly serializing via ByteStrings has also

Dear devs,
I have been under the impression for a while that you can write a
compact region to a file and the functions in GHC.Compact.Serialized
also seem to suggest this is possible.
https://hackage.haskell.org/package/ghc-compact-0.1.0.0/docs/GHC-Compact-Serialized.html
It seems like there
Patches I would like merged:
* Short ByteString Patch - seems stalled again
* My patches to allow compacting a ModIface - Need to put these up for review
* Make Q (TExp a) a newtype (Proposal 195
-https://github.com/ghc-proposals/ghc-proposals/pull/195) - Not yet
written but will not be a big
So we are clear here you are trying to store additional core bindings
other than the ones stored normally in the interface files?
It sounds like to me you might need to use `forkM` to make your custom
loading lazier.

Simon,
I think the issue was a missing entry in the .gitignore file. Ryan
fixed something to with that in this MR
(https://gitlab.haskell.org/ghc/ghc/-/merge_requests/3222) but he says
it was the dist-boot rather than dist-install directory.

Hi,
I noticed that the UniqMap module was removed from the tree
See 1c7c6f1afc8e7f7ba5d256780bc9d5bb5f3e7601
Why was it removed? I needed it today and now I am unsure what the
suitable replacement is.
As a general point, please can we stop with these annoying
refactorings which delete unused

Hi all,
I have hacked together a new profiling mode code named "Profile by
Info Table" which
uses the address of the info table as the band identity in the profile.
The main point of this is that you can then look up the source
location of the info table in the dwarf information when rendering
; dynamic libraries? If your GHC is dynamically linked the library DWARF info
> might be available in their respective .so's.

I followed the instructions on the wiki to enable debug symbols in my
build of GHC.
(https://gitlab.haskell.org/ghc/ghc/-/wikis/building/hadrian#enabling-dwarf-debug-symbols)
So I added these flags to may hadrian.settings file
