<pre>gcc supports -march=armv7ve option for arm but this is not supported by clang.
Armv7ve description:
armv7ve add supports for ARMv7 virtualization extension, including instructions
such as integer divide instructions.
This makes build scripts difficult to port to clang from gcc.
Example:
$ cat foo.c
int divide(int b, int c) {
return b/c;
}
$ gcc -march=armv7ve -c foo.c # This works as expected
Compiling with clang fails.
$ clang -march=armv7ve -c foo.cc
clang-4.0: error: the clang compiler does not support '-march=armv7ve'</pre>
