#3840: ghc-6.12.1 takes longer to compile code and produces bigger binaries
compared to ghc-6.10.4

Reporter: maeder | Owner:
Type: bug | Status: new
Priority: normal | Milestone: 6.12.2
Component: Compiler | Version: 6.12.1
Keywords: | Difficulty:
Os: Linux | Testcase:
Architecture: x86 | Failure: None/Unknown
-------------------------+--------------------------------------------------
Comment(by maeder):
I've attached a small subset of our sources that hopefully illustrate the
problem.
{{{
tar zxvf Hets.tgz
cd Hets
ghc --make -O -iatermlib/src Common/atc.hs
ls -S1sh */*.o */*/*.o */*/*/*.o
rm */*.o */*/*.o */*/*/*.o
}}}
The only packages required to compile are base, containers, array, old-
time, time and ghc-prim.
It'll compile 15 files. The generated instances are in the file
ATC/AS_Annotation.hs. The size of the file ATC/AS_Annotation.o is:
{{{
ghc-6.10.4: 116K
ghc-6.12.1: 528K
ghc-6.13.20100211: 196K
}}}
