I ran the test case on 3.4.1 through 4.1.2, all with the same error message.
This bug may be related to #25160.

Test Case:
#include <spe.h>

__ev64_fs__ x;

int main(void)
{
   x = __ev_fsabs(x);
   return(0);
}

O.K., x put in .bss:
C:\Controller>powerpc-elf-eabispe-gcc -c -Wa,-alhs=test.lst -fverbose-asm
-msdata=eabi -G 7 test.c

ERR, x put in .sbss (GCC4.1.2):
C:\Controller>powerpc-elf-eabispe-gcc -c -Wa,-alhs=test.lst -fverbose-asm
-msdata=eabi -G 8 test.c
test.c: In function 'main':
test.c:10: internal compiler error: in print_operand, at
config/rs6000/rs6000.c:
