Right. As part of D4762. That didn’t cover ghci though it seems ;)

Tamar, could you please have a look wrt. to libffi and windows?
Dec 4 2018
The ghci ffi guard breaks the build. Without it, this builds for me on macOS in ~40min for the default build.

Seems to build a ghc on macOS.
As determined on IRC today, the proper solution here is to likely teach hadrian about extra-libraries as specified in cabal files.
We currently hardcode some of the in hadrian, but should rather read them from the cabal files and fix the cabal files where
they are missing.

So we are looking for libffi as a dependency of ghci, that makes some sense as ghci does reference quite a bit of libffi symbols.
For completeness sake: here's the dead_strip_dylib documentation:
-dead_strip_dylibs Remove dylibs that are unreachable by the entry point or exported symbols. That is, suppresses the generation of load command commands for dylibs which supplied no symbols during the link. This option should not be used when linking against a dylib which is required at runtime for some indi- rect reason such as the dylib has an important initializer.
The question (to me) is: why doesn't ghc reference libffi if it needs it? Or are we bundling libffi just for convenience?
It doesn't build for me; bails out with some rather weird linker errors.
I wouldn't put it past my system to be screwing me over here. I'll have to try in a clean room install again.

Didn't manage to try it, but LGTM source wise.

Two minor issues, I'd appreciate to see addressed otherwise LGTM.

I have a concern about the LLVM implementation. using *usub*, while the primop name suggests it should be *uadd*.

@last_g if you do not intend to address LLVM in any way in this patch, does this mean it will potentially render the llvm backend broken? I'm not asking for the same functionality in the LLVM backend, just that we ensure not to break -fllvm.

Howdy @Phyx, I actually did try my luck on GHC 7.3; but this ended up being really messy. And then I have no idea how to build gcc/mingw on windows properly.

Note that while we have the fix in LLVM, the result only works with the llvm-ng backend, not with the stock llvm backend due to the excessive use of aliases in the stock backend, which confuses LLVM's entry-point logic.
May 23 2018
As @simonmar noted, the LLVM part is missing, I don't see any fundamental reasons why the LLVM backend could not support the same.
Similar to the -ffunction-sections question:
- has this been tested on macOS with -dead_strip, which uses the .subsections_via_symbols directive?
- The lack of symbols as @simonmar noted, is concerning to me as well, and I'm in the same boat, not making the connect with D4713 yet. Could you provide the same Perf-list without the D4713 interaction?

@trofi you might want to still try --via-asm with https://github.com/haskell/hsc2hs/pull/8. It might be faster, as we do not need to do the binary search for constants.
Ideally we'd also extend it to compute all constants in one go, instead of computing each on their own.
Ok, let's do this in 8.6.

won't make it in 8.4 anymore.

... and the windows build is green!
- Adds hvr's fix
- Windows, are we friends now?
Mar 1 2018
- add .buildinfo from dist/build into bindist-list
Feb 28 2018
- fix .buildinfo lookup for bindist
- in-place is the worst

for the record:
make: *** [utils/check-ppr/dist-install/build/Main.dyn_o] Segmentation fault: 11 make: *** Waiting for unfinished jobs.... make: *** [utils/check-api-annotations/dist-install/build/Main.dyn_o] Segmentation fault: 11 make: *** [utils/ghctags/dist-install/build/Main.dyn_o] Segmentation fault: 11 make: *** [all] Error 2
This does however cause my stage2 ghc to segfault, and I have no idea why...

Sorry to be a bit late to the party 🎉
@bgamari yey, everything is green... except for Linux which fails with Haddock 🗡

Lovely, haddock is failing... what the hell?
