JB, that is the same toxic response that Dave was shining a light on.?
Good job!
Dave, thanks for bringing this to our attention.? Since Motion is one of
the "apps" you mention, it is very relevant to the readers of this
mailing list.
People may not understand the motivation for companies to sabotage OSS
(Open Source Software), but it's real, and it's all for profit.? If they
make the x86 code generation less efficient via the compiler, especially
for older CPU's, then most people will just think they need a new
computer, and viola, a new sale is the result.
Sticking your head in the sand about the issue is your prerogative, but
will not help the situation.

If there is a problem some of the programmers out there should chime in and *be
specific about what the problems are* *in layman's terms*. Also what do we
do about it other than complain? I am one of those people that would not
know. I do compile things occasionally including motion on a Fedora box.

Harlan,
? Unfortunately this problem doesn't have an easy solution (other than
using a non-GCC based tool chain).? Alternate tool chains would likely
require the user to purchase them, which most people won't do.
? The problem the link outlines is the compiler generates less
efficient code than it should, and those involved in the development of
GCC are not receptive to input on fixing it (quite the opposite actually).
? In layman's terms, anything built with GCC, including the Linux
kernel, system drivers, and applications (like Motion) would run slower
(use more CPU cycles) and consume more memory than they would otherwise
(at least on x86 architectures).? Until someone produces an alternative
to GCC, with better optimization, we're pretty much stuck with what we
have today.? Maybe someone will introduce a fork to GCC, that provides
those improvements.
