Hadrian compiles GHC without interpreter even on platforms that support it
While compiling GHC 9.4.7 on mips64el, I noticed that GHC was compiled without interpreter support. In contrast, when compiling using the old make system (again on mips64el) GHC is compiled with interpreter support as expected.
Taking a look at the code, we can see that Hadrian has a hard-coded list to decide which targets support GHCi (see https://gitlab.haskell.org/ghc/ghc/-/blob/00920f176b0235d5bb52a8e054d89a664f8938fe/hadrian/src/Oracles/Setting.hs#L289). In contrast, the old make build system has a different logic to decide which targets support GHCi (see https://gitlab.haskell.org/ghc/ghc/-/blob/00920f176b0235d5bb52a8e054d89a664f8938fe/mk/config.mk.in#L178). If I understand the code correctly, the old make build system enables GHCi on all platforms that support shared libraries, which means all platforms except for powerpc-ibm-aix
, x86_64-unknown-mingw32
and i386-unknown-mingw32
.
Please consider extending Hadrian to use the same logic as the old build system, and compile GHC with interpreter support on all platforms that support shared libraries.
