I only try to use the simulator until my account to access the blades is
enabled.

When I compiled the source I did a little mistake, I forgot to change
spu-gcc to spu-gcc43 and it compiled fine. Then I changed to spu-gcc43
an I got this error:
spu-gcc43 -O3 -W -Wall -Winline -Wmissing-prototypes -Wno-main -I.
-I/opt/cell/sysroot/opt/cell/sdk/usr//spu/include
-I../../../../../src/mesa/ -I../../../../../src/mesa
-I../../../../../src/gallium/include
-I../../../../../src/gallium/auxiliary
-I../../../../../src/gallium/drivers -DSPU_MAIN_PARAM_LONG_LONG -include
spu_intrinsics.h -c spu_texture.c
spu_texture.c: In function 'get_four_texels':
spu_texture.c:100: error: parameter list does not match a valid
signature for spu_splats()

this is line 100 of :
   const qword tile_size = (qword) spu_splats(sizeof(tile_t));

spu_splats() is in gcc-4.3 a builtin an does not recognize size_t as
valid argument-type. I changed the line as follows and it compiled fine.
   const qword tile_size = (qword) spu_splats((unsigned int)sizeof(tile_t));


I don't know if this is a good idea to simply cast it  to unsigned int
or if this is a a bug of the builtin spu_splats().


Kind regards,
