            Bug ID: 66746
           Summary: Failure to compile #include <x86intrin.h> with -miamcu
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: thiago at kde dot org
  Target Milestone: ---

Source code:
#include <x86intrin.h>

Compiling with:
  gcc -m32 -miamcu -c test.c

Produces a couple thousand errors, starting with:

/home/thiago/obj/gcc/gcc/include/ia32intrin.h:54:28: sorry, unimplemented: SSE
isn’t supported in Intel MCU psABI
 #pragma GCC target("sse4.2")
                            ^
/home/thiago/obj/gcc/gcc/include/ia32intrin.h:61:46: sorry, unimplemented: SSE
isn’t supported in Intel MCU psABI
 __crc32b (unsigned int __C, unsigned char __V)
                                              ^

I don't want to use SSE, but x86intrin.h has useful intrinsics for instructions
from as early as the 8086 (like __ror[bwd]). This header should compile.

Log:
Allow <adxintrin.h> for IA MCU

It is OK to include <adxintrin.h> for IA MCU since GCC can generate ADX
intrinsics with alternative instuctions if ADX isn't enabled.

        * config/i386/x86intrin.h: Include <adxintrin.h> even if
        __iamcu__ is defined.
