Subject: intrinsics and sign-conversion
Date: Fri, 17 Mar 2023 10:22:21 +0100	[thread overview]
Message-ID: <CA+7wUszo4Xm17JKkW7BQiNrEnEczvNrLx02NpMjD2X5=rx6Ymg@mail.gmail.com> (raw)

Hi all,

I am trying to understand why I cannot get gcc to trigger a
sign-conversion warning on the following:

% cat tu.c
#include <immintrin.h>

extern unsigned int bar();

__m128i foo(__m128i a)
{
    return _mm_srai_epi64(a, bar());
}

On Debian/sid:

% gcc-12 -c  -mavx512vl -Wsign-conversion -Werror tu.c && echo "success"
success

Thanks,
-- 
Mathieu
