#3725: Annotations not written to interface files
---------------------------------+------------------------------------------
Reporter: rl | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.13 | Keywords:
Os: Unknown/Multiple | Testcase:
Architecture: Unknown/Multiple | Failure: Other
---------------------------------+------------------------------------------
Small example:
{{{
module C where
data T a = T a
}}}
Compile it:
{{{
newbie:tests rl$ ~/projects/ndp/ghc/inplace/bin/ghc-stage2 -O2 -c C.hs
newbie:tests rl$ ls -l C.hi
-rw-r--r-- 1 rl rl 485 4 Dec 12:53 C.hi
}}}
Add an annotation: `{-# ANN type T () #-}`. Compile:
{{{
newbie:tests rl$ ~/projects/ndp/ghc/inplace/bin/ghc-stage2 -O2 -c C.hs
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
newbie:tests rl$ ls -l C.hi
-rw-r--r-- 1 rl rl 485 4 Dec 12:53 C.hi
}}}
Note that the interface file hasn't been updated. Remove `C.hi` and
recompile:
{{{
newbie:tests rl$ rm C.hi
newbie:tests rl$ ~/projects/ndp/ghc/inplace/bin/ghc-stage2 -O2 -c C.hs
Loading package ghc-prim ... linking ... done.
Loading package integer-gmp ... linking ... done.
Loading package base ... linking ... done.
Loading package ffi-1.0 ... linking ... done.
newbie:tests rl$ ls -l C.hi
-rw-r--r-- 1 rl rl 507 4 Dec 12:54 C.hi
}}}
Only now has the annotation been written to `C.hi`.
