            Bug ID: 97028
           Summary: Compilation errors for AVX512 intrinsic with
                    -masm=intel
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: nikita.shulga at gmail dot com
  Target Milestone: ---

Following code snippet, containing no asm blocks can be compiled just fine with
'-Os -mavx512f' options, by compilation fails using gcc-9.0 or newer if
'-masm=intel' is added:
#include <immintrin.h>

float foo(float* con) {
    __mmask16 msk = 0x00ff;
    __m512 a = _mm512_maskz_loadu_ps(msk, con);
    __m512 b = _mm512_set1_ps(con[1]);
    __m512 c = _mm512_mul_ps(a,b);
    return ((float *)&c)[0];
}

That is:
$ gcc -c -Os -mavx512f mul.c ; echo $?
0
$ gcc -c -Os -masm=intel -mavx512f mul.c ; echo $?
/tmp/ccmeN1OP.s: Assembler messages:
/tmp/ccmeN1OP.s:12: Error: invalid use of register
1

And the offending instruction looks as follows:
$ gcc -S -o - -Os -masm=intel -mavx512f mul.c|head -n 12|tail -n1
        vmulps  zmm0, zmm0, DWORD PTR [rdi+4]<{1to16}>

But compilation works just fine if gcc-8 is used instead.

it works for me, what assembler version are you using?  I'm using gas 2.34.0
