[Bug c/22177] New: error: in assign_stack_temp_for_type, at function.c:655

[zhr_buaa at 263 dot net]

this bug occured when compiling the mplayer, file dsputil.c:3243.
here is the compiler report:
dsputil.c:3243: internal compiler error: in assign_stack_temp_for_type, at
function.c:655
the compiling code segment is:
   3237 static int rd8x8_c(/*MpegEncContext*/ void *c, uint8_t *src1, uint8_t
*src2, int stride, int h){
   3238     MpegEncContext * const s= (MpegEncContext *)c;
   3239     const uint8_t *scantable= s->intra_scantable.permutated;
   3240     uint64_t __align8 aligned_temp[sizeof(DCTELEM)*64/8];
   3241     uint64_t __align8 aligned_bak[stride];
   3242     DCTELEM * const temp= (DCTELEM*)aligned_temp;
   3243     uint8_t * const bak= (uint8_t*)aligned_bak;
   3244     int i, last, run, bits, level, distoration, start_i;

Could you add -save-temps to the command line which is compiling the file and attach the 
preprocessed source?

Also could you supply how you run gcc?

We need the preprocessed source file to be able to reproduce it.

this is my command line to compile the source file. then, i change the option -c
to -E and option -o, to generate the dsputil.i. wish this can help u.

[Bug middle-end/22177] [3.4 only] error: in assign_stack_temp_for_type, at function.c:655

[pinskia at gcc dot gnu dot org]

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-06-27 13:38 -------
Reduced testcase:
int rd8x8_c( int stride)
{
    unsigned long long __attribute__ ((aligned (4))) aligned_bak[stride];
    unsigned char * const bak= (unsigned char*)aligned_bak;
}


Confirmed, only happens on the 3.4 branch, I don't know if this is a regression or not so keeping this 
bug opened.

Not a regression since iwwmxt support was new in 3.4

Note that you cannot use __attribute__((aligned (4))) to reduce the alignement
of an object, so this code is invalid (code compiled for iwmmxt processors
requires an ABI change where long long objects are 8-byte aligned).
