--- Comment #3 from Paul Floyd <paulf at free dot fr> ---
With clang 17.0.2 (also tried 14.0) I get
0000000000000000 <function>:
0: 55 push %rbp
1: 41 57 push %r15
3: 41 56 push %r14
5: 41 55 push %r13
7: 41 54 push %r12
9: 53 push %rbx
a: 48 81 ec c8 23 00 00 sub $0x23c8,%rsp
11: c5 f9 28 c1 vmovapd %xmm1,%xmm0
15: 4c 89 8c 24 98 21 00 mov %r9,0x2198(%rsp)
With GCC if I add -mno-avx then I get back the base pointer. I presume that
this will turn off all vector extensions from avx onwards.
