Extended Description

For the c language input:

void sub1(void) {
printf("in sub1\n");
}
int main(unsigned long long id) {
sub1();
printf("returned from sub1\n");
return 0;
}

When the llc command with the option -march=cellspu is run, the code generated in the assembly file:
brsl $lr, sub1-.
should not have the -. appended to the target.

If the -. is removed and the code is assembled and linked for the spu the test will execute successfully.

Note that external symbols such as:
brasl $lr, printf
do not have the decoration.

The same bitcode will generate correct output with the llc command and the -march=ppc32:
bl sub1
