<P>The <I>background</I> : there were/are the GCC <B>2.95</B> series. The
|
|
|
|
|
best of them was 2.95.3 . Please note the style of the version numbering.
|
|
|
|
|
This is how the GCC team numbers their compilers. The 2.95 series are good.
|
2001-11-14 22:45:53 +00:00
|
|
|
We never ever saw anything that was miscompiled because of the 2.95's faultiness.</P>
|
2001-11-13 16:19:48 +00:00
|
|
|
|
|
|
|
|
<P>The <I>action</I> : <B>RedHat</B> started to include a GCC version of <B>2.96</B>
|
|
|
|
|
with their distributions. Note the version numbering. This should be the GCC
|
2001-11-14 22:45:53 +00:00
|
|
|
team's versioning. They patched the CVS version of GCC (something between 2.95 and 3.0)
|
2001-11-15 20:05:52 +00:00
|
|
|
They patched it very deep, and used this version in the distrib because 3.0
|
|
|
|
|
wasn't out at time, and they wanted IA64 support ASAP (business reasons).
|
|
|
|
|
Oh, and GCC 2.95 miscompiles bash on the s390 architecture (there is
|
|
|
|
|
no RedHat distribution for s390..) .</P>
|
|
|
|
|
|
|
|
|
|
<P>The <I>facts</I> : <B>MPlayer</B>'s compile process needs the
|
|
|
|
|
<CODE>--disable-gcc-checking</CODE> to proceed upon detecting a GCC version of
|
|
|
|
|
2.96 (apparently it needs this option on <B>egcs</B> too. It's because we don't
|
|
|
|
|
test <B>MPlayer</B> on egcs. Pardon us, but we rather develop <B>MPlayer</B>).
|
|
|
|
|
If you know <B>MPlayer</B>, you should know that it has great speed. It
|
|
|
|
|
achieves this by having overoptimized MMX/SSE/3DNow/etc codes, fastmemcpy, and
|
|
|
|
|
lots of other features. <B>MPlayer</B> contained MMX/3DNow instructions in a
|
|
|
|
|
syntax that all Linux compilers accept it... except RedHat's GCC (it's more
|
|
|
|
|
standard compliant). It simply <B><I>skips</I></B> them. It doesn't give
|
2001-11-16 22:26:47 +00:00
|
|
|
errors. It doesn't give warnings. <B>And</B>, there is Lame. With gcc 2.96, its quality check
|
|
|
|
|
(<CODE>make test</CODE> after compiling) <I>doesn't even run !!!</I>
|
|
|
|
|
But hey, it compiles bash on s390 and IA64.</P>

2001-11-13 16:19:48 +00:00

|
|
|
|
|
|
|
<P>The <I>statements</I> : most developers around the world begun having
|
|
|
|
|
bad feelings about RedHat's GCC 2.96 , and told their RedHat users to
|
|
|
|
|
compile with other compiler than 2.96 . RedHat users' disappointment slowly
|
2001-11-14 22:45:53 +00:00
|
|
|
went into anger. What was all good
|
2001-11-13 16:19:48 +00:00
|
|
|
for, apart from giving headaches to developers, putting oil on anti-RedHat
|
|
|
|
|
flame, confusing users? The answer, I do not know.</P>
|
|
|
|
|
|
|
|
|
|
<P><I>Present age, present time</I> : RedHat says that GCC 2.96-85 and above
|
|
|
|
|
is fixed, and works properly. Note the versioning. They should have started
|
2001-11-14 22:45:53 +00:00
|
|
|
with something like this. What about GCC 2.96.85 ? It doesn't matter now.
|
|
|
|
|
I don't search, but I still see bugs with 2.96 . It doesn't matter now,
|
|
|
|
|
hopefully now <B>RedHat will forget about 2.96</B> and turn towards <B>3.0</B>.
|
|
|
|
|
Towards a deep patched 3.0...

<P><I>What I don't understand</I> is why are we hated by RedHat users for
|
|
|
|
|
putting warning messages, and stay-away documents in <B>MPlayer</B> .
|
|
|
|
|
Why are we called "brain damaged", "total asshole", "childish" by
|
|
|
|
|
<B>RedHat users</B>, on our mailing list, and even on the <B>redhat-devel</B> .
|
|
|
|
|
They even considered forking <B>MPlayer</B> for themselves. RedHat users.
|
|
|
|
|
Why? It's RedHat that made the compiler, why do <U>you</U> have to hate us?
|
|
|
|
|
Are you <U>that</U> fellow RedHat worshippers? Please stop it. We don't hold
|
|
|
|
|
a grudge against users, doesn't matter how loud you advertise its contrary.
|
|
|
|
|
Please go flame Linus Torvalds, the DRI developers (oh, now I know why
|
|
|
|
|
there were laid off by VA!), the Wine, avifile. Even if we are arrogant,
|
|
|
|
|
are we not the same as the previously listed ones? Why do <B>we</B> have

to suffer from your unrightful wrath?</P>

<P>I'm closing this topic. Think over it please. I (Gabucino) personally begun

with <A HREF="http://www.redhat.com">RedHat</A>, then used Mandrake (sorry I

|

don't know their URL), now I have <A

|

HREF="http://www.linuxfromscratch.com">LFS</A>. Never held a grudge against

|
|
|

RedHat or RedHat users, and I still don't. Hate is only comfortable. It

|
|
|
|
won't bring you anywhere.</P>

<P>Tons of users asked us about this. For example Debian users tend to say: Oh,

<LI><B>MPlayer's</B> speed (MMX, SSE, fastmemcpy, etc) optimizations are

processor-specific code. An <B>MPlayer</B> binary compiled for K6 will die

on Pentiums and vice versa. This has to be workarounded by runtime

detection, which is not an easy thing to do becase it causes massive speed

<P>We don't like nvidia's binary drives, their quality, unstability,

non-existant user support, always appearing new bugs. And most users behave

the same. We've been contacted by NVidia lately, and they said these bugs

|
|
|
|
don't exist, unstability is caused by bad AGP chips, and they received
|
|
|
|
|
no reports of driver bugs (the purple line, for example). So: if you have

problem with your NVidia, update the nvidia driver and/or buy a new

years ago. He was an OS/2 advocate then (I was an OS/2 fan too).

He used to go over-the-top, flaming people, and I suspect he had some hard
