Comment 5 slapcat 2003-02-28 17:28:28 UTC
try building with debugging on

find the line in the mplayer rc4 ebuild:

  local myconf=""

and add:

  local myconf="--enable-debug=3"

emerge mplayer again and gdb will now tell the exact line where the failure occurred

Do you happen to be using a 2.4.20 kernel ?
When you try nano or top, does it do "Illegal instruction" also ?

>s> :) nano, X11, top, xine, mozilla, mc, etc. works ok. There isn't any another one program that does illegal operation.
Comment 12 Martin Schlemmer (RETIRED) gentoo-dev 2003-03-23 10:42:51 UTC
Please try rc5, or try with 2.4.19 kernel.

sorry i can't do test with 2.4.19

could you please attach your

Comment 16 James Bowlin 2003-04-11 17:15:23 UTC
I ran into the same problem trying to see the animatrix video.   I think I know what is going 
wrong.  I have fairly relaxed CFLAGS: "-Os -march=pentium3 -fomit-frame-pointer -pipe" 
but when I watched mplayer compiling I saw a lot of "-O4" and "-march=pentium4". 
 
I've got an Intel(R) Pentium(R) 4 Mobile CPU 1.60GHz. 
 
My guess is that we are encountering the fabled gcc "pentium4 bug".  And I guess further that 
this bug is *very* CPU dependent: all Pentium 4's are equal but some are more equal than others. 
 
I will test this by manually compiling with less agressive gcc flags.  Any pointers to tips on how 
to do this would be appreciated.  I'll start out by re-reading the Gentoo docs on manually 
ebuilding step by step.    A grep "pentium" of the ebuilds turned up nothing so I think the 
aggresive flags are coming from a makefile(s).   
 
If I am correct, for extra credit we could try to get a list of which CPU models barf here.  
That info might be very useful to the gcc folks.  It might also be useful to us so that everyone 
can emerge a working mplayer. 
 
Comment 17 Sven Vermeulen (RETIRED) gentoo-dev 2003-04-14 16:54:41 UTC
Same goes here. Removing "unset CFLAGS CXXFLAGS" in the ebuild made the problem disappear. Athlon XP in laptop. Using own CFLAGS works without any troubles.
Comment 18 Martin Schlemmer (RETIRED) gentoo-dev 2003-04-15 18:52:54 UTC
So basically mplayer's configure script detects your processor type wrong ?
Either please attach a full log of 'emerge mplayer', or try to figure
out what it sets CFLAGS to, and if possible what flag causes the problem.

cvttss2si instruction does some bad job.
1. from which instruction subset comes this opcode (mmx/3dnow/sse ...)
2. find function/.c file which produse this binary code
3. submit smal test case to mplayer and gcc devel teams
 thanks.

I think this is gcc, issue
Comment 23 Marc Hildebrand (RETIRED) gentoo-dev 2003-10-30 01:03:51 UTC
Hmmm, I had a similar problem once...
Please check the "sse-status" of you athlon-xp.
If you do dual-boot, boot into win and use some cpuinfo-prog to check if
sse is enabled (if you have tmpeg you can see it in it's option dialog as
well).
If sse is disabled, check your motherboard vendor for bios-updates (I had
to).
If sse is enabled, boot linux and check /proc/cpuinfo for sse.
If it's not there it's not enabled by the kernel, so everything using sse
will lead to an illegal instruction.
Try some other kernel, I know the latest tested gentoo-sources work well
on my machine but if you are willing to play around a bit I recommend the
2.6.0 series.
Please post your results here.
Cheers,
Marc

It work's! 2.4.23 enables sse on AMD Athlon XP on boot.

Comment 25 roma1390 2003-12-27 07:03:17 UTC
btw: early test shows, that mplayer was compiled with 
CPUflags:  MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 0 SSE2: 0
Compiled for x86 CPU with extensions: MMX MMX2 3DNow 3DNowEx
now it's compiles as:
CPUflags:  MMX: 1 MMX2: 1 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 0
Compiled for x86 CPU with extensions: MMX MMX2 3DNow 3DNowEx SSE

this means, that mplayer knows that i did't have sse, but uses cvttss2si instruction.

This can be mplayer/gcc problem. If this code with cvttss2si is generated from gcc, then this is gcc problem, or problem with wrong gcc parameter. OR this code is optimised in mplayer using asm, and this asm code is wrong writen.
