And for the people, who periodically asks what are the exact problems with
|
|
gcc 2.96, my answer: <I>we don't know.</I> We just see various bugreports mostly
|
|
gcc internal bugs, compiler syntax errors in source or bad code compiled. They
|
|
all are solved using different version of gcc. I understand that gcc 2.96
|
|
has different default optimization flags and they conflicts with our inline
|
|
asm code, but we can't fix them, and we really don't want to fix them as they
|
|
work with other compilers or gcc versions, and the fix may cause speed loss.
|
|

I think that the gcc 2.96 should be fixed to be option-compatible with other
|
|
releases, but redhat guys refused to do it. If someone interested - ask
|
|
Eugene K., avifile author, he has a long mailing with them, because they had
|
|
the same problems with avifile. Finally he changed avifile source to
|
|
<I>workaround</I> gcc 2.96 bugs...
|
|
We simply has no interest and time to do it.

Ah, and about the pipe-in-comment bug: it wasn't really our bug.
|
|
I've talked one of gcc maintainers, and he told me that gcc 2.96 and 3.x
|
|
supports intel asm syntax, and it caused the pipe bug. But it was a bug,
|
|
because gcc silently, without any warning, ignored the whole asm block.
|
|
*They* have fixed that, now it prints warning and doesn't skip the block.
|
|
(at least he told me, i didn't checked)

Other gcc 3.x problems comes from broken libstdc++ or glibc header (std_*.h)
|
|
installation. They are not our fault. MPlayer compiles and works well with
|
|
gcc 3.x versions. <B>Only 2.96 is broken</B>, but it depends on many environment
|
|
elements, including gcc 2.96 release number, enabled mplayer features, etc.
|
|
<I>If it works for you using gcc 2.96, it doesn't mean it will work for everyone.</I>
