List of functions missing from 32-bit arm_neon.h

You're right, sorry.  I'm not sure why I was thinking that header was shared.

It looks like there are a *lot* more of these.  Based on a quick script to grep
arm_neon.h for each function listed on ARM's web site
()
as v7/A32 or v7/A32/A64 there are 47 functions missing (plus another 108 if you
include the *_x1/2/3/4 functions, and another 145 if you include the
poly/f16/bf16 stuff).

Here is a list of those first 47:

  vcvtaq_s32_f32
  vcvtaq_u32_f32
  vcvta_s32_f32
  vcvta_u32_f32
  vcvtmq_s32_f32
  vcvtmq_u32_f32
  vcvtm_s32_f32
  vcvtm_u32_f32
  vcvtnq_s32_f32
  vcvtnq_u32_f32
  vcvtn_s32_f32
  vcvtn_u32_f32
  vcvtpq_s32_f32
  vcvtpq_u32_f32
  vcvtp_s32_f32
  vcvtp_u32_f32
  vfma_n_f32
  vfmaq_n_f32
  vld2q_dup_f32
  vld2q_dup_s16
  vld2q_dup_s32
  vld2q_dup_s8
  vld2q_dup_u16
  vld2q_dup_u32
  vld2q_dup_u8
  vld3q_dup_f32
  vld3q_dup_s16
  vld3q_dup_s32
  vld3q_dup_s8
  vld3q_dup_u16
  vld3q_dup_u32
  vld3q_dup_u8
  vld4q_dup_f32
  vld4q_dup_s16
  vld4q_dup_s32
  vld4q_dup_s8
  vld4q_dup_u16
  vld4q_dup_u32
  vld4q_dup_u8
  vreinterpretq_f64_u64
  vrndi_f32
  vrndiq_f32
  vrndn_f64
  vrndnq_f64
  vrndns_f32
  vst3q_lane_s8
  vst3q_lane_u8

I'm not sure how reliable ARM's documentation is... I see that there are
several f64 functions in that list, and I always thought those were supposed to
be exclusive to AArch64.  Assuming ARM's documentation is accurate, though, all
the functions I've checked do seem to be legitimately missing (i.e., I haven't
seen any false positives from my script).

I'm attaching the full list (300 functions), not sure how you want me to handle
this.  Should I file separate bugs for each group (i.e., this one could be for
vcvt*, another one for vrnd*, another for vfma*, etc.)?  One for all of them? 
Or just use this bug for all of them?

Hmm... I see them present for aarch64 and even in the gotbolt setup you
provided (use ARM64 gcc 8.2)
They do seem to be missing from arm though indeed
