GCC 4.4.1-tdm-2 for MinGW (with installer)

<< < (5/8) > >>

Conan Kudo:
How about an MinGW-w64 version? Is that in the pipeline?

TDragon:
killerbot: yes.

Pharaoh Atem: maybe.

I found a problem with 4.4.1-tdm-2, regarded to the optimization. I observe a lost of precision in numeric code if "O" flags are used. In case of O1 it is small, but not negligible, in case of O2 it is intolerable.
I found that errors occurs when "O" flags are used, from "O1". If the the same set of the command-line optimization options introduced separately as it described in GCC manual, no problem detected up to "-fexpensive-optimizations".

TDragon:
Have you observed similar problems in the official MinGW release(s)?

I not tried official release. Looks like problem not exists in 4.4.0-tdm. At least I do not found it, but I used it a lot.
