gcc 8 for mingw?

Post by Dann Corbit » Sat May 19, 2018 6:20 am

Anyone know of a working gcc 8.x for mingw on Windows platforms?
I am still in the stone age with 7.3.0-2
Might be a limitation of MSYS2

Not what you are looking for but here is my experience with Linux ...

I've been getting slower binaries with gcc5, gcc6, and gcc7, both PGO and non-PGO compare to gcc4.8

gcc8 is the first to produce an actual speedup over gcc4.8. Additionally, one of my machines builds
a 10% faster binary using the PGO. The other a 5% slower one. YMMV.

Hello Dann, mingw64 8.1 is out since a few days :
https://sourceforge.net/projects/mingw- ... posix/seh/

Unfortunately, as far as Orion is concerned, I didn’t notice any speed improvement over 7.3...!
