obsolete switch -OG
« on: November 15, 2007, 10:23:47 am »
Hi,
When compiling a program I get the warning: You are using the obsolete switch -OG.
What does it mean?

Check compiler options and remove the -OG switch?
No idea what it used to do, and if it is replaced by some other switch.

-OG generated faster code, -Og smaller. Today fpc uses -Os to generate smaller code, so I suppose that omitting it, will generate faster code  :)

Type fpc with no argument for further information, some switches are obsolete. I think Lazarus' compiler option dialog should be changed due to this change.
