GCC48 and G++48 "CFLAGS"

[Originale 161]

Hi everyone  

 

For those using gcc48 and g+ +48 I just ask that you optimize use? 

 

I use these CFLAGS

 

CC = g++48

CFLAGS =  -Wall -O3 -std=c++11 -g -pipe -mtune=i686 -fno-rtti -fno-exceptions -pthread -D_THREAD_SAFE

Change -mtune to the target cpu type.

Eg. with enabled ssse3 program will run 10% faster (if the CPU supports)...

Thank you for your reply ATAG

 

I would have done like this

 

-mtune=core2 ?

 

My Proc: core 2 duo E8500

 

Edit: I must put the CFLAGS equal in all serv?

If you compile on the target machine, use -mtune=native it will turn on all CPU flags, that your CPU supports.

I also saw a post you made ​​avai or you talk to remove-g and-wall

I save a lot on the size of the file
