Hello, I was experimenting with compiler flags trying to tune some performance and got something unexpected with the -fno-pre-inlining flag. I was hoping somebody here might be able to clarify an issue for me. When compiled with -fno-pre-inlining, my test program gives a different result than compiled without (0.988... :: Double, compared to 1.0). It's numerical code, and was originally compiled with -fexcess-precision, however I have tried both with and without -fexcess-precision and the results are the same. The only other compiler flags in use are -O2 and --make. Is this expected behavior or a possible bug? I believe the value with -fno-pre-inlining is correct (and runs about 30% faster too). This was done on an OSX 10.5 Macbook with GHC-6.10.3. I could check this on some other systems if it would be helpful. Sincerely, John Lato
