Hi,
The build for ghc-cryptonite failed in the mass rebuild [1] and a
later rebuild by me [2], but only on s390x. The failure appears to be
LTO related. This doesn't appear to affect many other Haskell
packages. (I've found one seemingly-related failure in
ghc-haskell-src-exts [3].) Since it's Haskell, I'm using the standard
macros that should pass consistent flags, etc., so I'm not sure what
more information I can provide.
What happens is that ld.gold warns about mixed LTO/non-LTO:
[ 1 of 131] Compiling Crypto.Cipher.DES.Primitive (
Crypto/Cipher/DES/Primitive.hs,
dist/build/Crypto/Cipher/DES/Primitive.p_o )
/usr/bin/ld.gold: warning: incremental linking of LTO and non-LTO
objects; using -flinker-output=nolto-rel which will bypass whole
program optimization
and then errors out because of many LTO mismatches like:
/tmp/ghc794663_0/ghc_19.c:11:19: error:
