Hi I have the following ARM Linux program. The program detects if the processor has division instruction, if it does, it uses it, otherwise it uses slower library call. The program works with gcc, but it doesn't work with clang. clang reports error on the sdiv instruction in the assembler. The problem is this - you either compile this program with -mcpu=cortex-a9, then clang reports

...e directives are used ".cpu cortex-a15\n .fpu neon-vfpv4". LLVM integrated assembler will choke on it and produce invalid object file. You can try: int main(void) { asm volatile (".cpu cortex-a15\n .fpu neon-vfpv4\n"); return 0; } /usr/bin/ld: Warning: /tmp/as-b084f5.o: Unknown EABI object attribute 488 /usr/bin/ld: /tmp/as-b084f5.o: Unknown mandatory EABI object attribute 8890 /usr/bin/ld: failed to merge target specific data of file /tmp/as-b084f5.o Maybe, all you need to do is fix handling of these directives in the integrated assembler. > When that s...
