[Bug 383240] Re: Integrate and enable ARMv5TE/v6/VFP and NEON optimisations from ffmpeg trunk for armel

[Loïc Minier]

Back to aes.o, this is the shared pass:
gcc -DHAVE_AV_CONFIG_H -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -I. -I"/build/buildd/ffmpeg-0.5+svn20090706" -D_ISOC99_SOURCE -D_POSIX_C_SOURCE=200112 -I/build/buildd/ffmpeg-0.5+svn20090706/debian/include -std=c99 -fomit-frame-pointer -march=armv6 -pthread -I/usr/include/schroedinger-1.0 -I/usr/include/liboil-0.3 -g -Wdeclaration-after-statement -Wall -Wno-switch -Wdisabled-optimization -Wpointer-arith -Wredundant-decls -Wno-pointer-sign -Wcast-qual -Wwrite-strings -Wtype-limits -Wundef -O3 -fno-math-errno -fno-signed-zeros          -c -o libavutil/aes.o /build/buildd/ffmpeg-0.5+svn20090706/libavutil/aes.c

This is the neon pass:
gcc -DHAVE_AV_CONFIG_H -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -I. -I"/build/buildd/ffmpeg-0.5+svn20090706" -D_ISOC99_SOURCE -D_POSIX_C_SOURCE=200112 -I/build/buildd/ffmpeg-0.5+svn20090706/debian/include -mfpu=neon -mfloat-abi=softfp -std=c99 -fomit-frame-pointer -march=armv7-a -pthread -I/usr/include/schroedinger-1.0 -I/usr/include/liboil-0.3 -g -Wdeclaration-after-statement -Wall -Wno-switch -Wdisabled-optimization -Wpointer-arith -Wredundant-decls -Wno-pointer-sign -Wcast-qual -Wwrite-strings -Wtype-limits -Wundef -O3 -fno-math-errno -fno-signed-zeros          -c -o libavutil/aes.o /build/buildd/ffmpeg-0.5+svn20090706/libavutil/aes.c

So it would seem -mfpu=neon does not generate PIC code in some cases;
perhaps -fPIC is missing?
