Hi all,
We are in the process of Porting X86 Flash Player Code to DaVinci
ARM. We build the source with modifications in Makefile and by reducing
optimization level from O3 to O2 (since we got internal compiler error when
building with O3).
Before running the swf files with the built application, we execute startx &
and export DISPALY=0:0 When we run the swf file with compiled application, the
player closes immediately giving following error
Alignment trap: standalone-640- (1357) PC=0x00094ab8 Instr=0xe5810000
Address=0x40e22532 FSR 0x813
Bus error
After i executed the instruction echo 2 > /proc/cpu/alignment to hide the
alignment trap then i run the same application. I could able to run the .swf
files but its too slow. performance is very bad.
At the end of running the .swf file, Segmentation fault is displayed on the
console.
I saw the number of alignment traps as follows.
[EMAIL PROTECTED]:/workdir/tmp# more /proc/cpu/alignment
User: 28018915
System: 0
Skipped: 0
Half: 0
Word: 28018914
DWord: 0
Multi: 0
User faults: 2 (fixup)
There are millions alignment traps we can see.
Please suggest how to solve Alignment Trap Problem? and How to improve the
performance?
