<pre>This works correctly:
$ cat test.c
void foo() {
asm ("fadd.s f1, f2, f3");
asm ("fadd.d fa0, fa1, fa2");
}
$ clang --target=riscv32 -O2 -S test.c -o-
(...)
foo: # @foo
# %bb.0: # %entry
#APP
fadd.s f1, f2, f3
#NO_APP
#APP
fadd.d fa0, fa1, fa2
#NO_APP
ret
(...)
If anything, I wonder if that works more than it should, since we accept that
inline assembly even when not targetting the floating-point extensions.</pre>
