driver: Something fishy about file output with -fno-code -fwrite-interface
Consider these modules:
https://gist.github.com/2656b7f38c0546aece7ecee198dbf686
Then if I run
../_build/stage1/bin/ghc S.hs -fno-code -fwrite-interface
Then the resulting files are
S.dyn_o S.hi S.hs S.o T.dyn_hi-boot T.dyn_o T.hi T.hi-boot T.hs T.hs-boot T.o
Notice there is no .o-boot
or dyn_o-boot
files produced.
But if you look at the progress output, it claims T.hs-boot
produces T.dyn_o
, that is surely wrong.
[1 of 3] Compiling T[boot] ( T.hs-boot, nothing, T.dyn_o )
[2 of 3] Compiling S ( S.hs, S.o, S.dyn_o )
[3 of 3] Compiling T ( T.hs, T.o, T.dyn_o )
Something doesn't add up.
