Clang build issues

[ArsMasiuk]

There are following issues reported by clang-msvc under Windows (64 bit):

In file included from C:\Work\Test\End.Expert.V2.LLVM\Code\ExtLibs_Include\simd-4.8.103\Simd/SimdMemory.h:29: In file included from C:\Work\Test\End.Expert.V2.LLVM\Code\ExtLibs_Include\simd-4.8.103\Simd/SimdMath.h:29: C:\Work\Test\End.Expert.V2.LLVM\Code\ExtLibs_Include\simd-4.8.103\Simd/SimdConst.h(94,36): error: excess elements in vector initializer const __m128i K_INV_ZERO = SIMD_MM_SET1_EPI8(0xFF); ^~~~~~~ C:\Work\Test\End.Expert.V2.LLVM\Code\ExtLibs_Include\simd-4.8.103\Simd/SimdInit.h(104,40): note: expanded from macro 'SIMD_MM_SET1_EPI8' {SIMD_AS_CHAR(a), SIMD_AS_CHAR(a), SIMD_AS_CHAR(a), SIMD_AS_CHAR(a), \ ^~~~~~~ C:\Work\Test\End.Expert.V2.LLVM\Code\ExtLibs_Include\simd-4.8.103\Simd/SimdInit.h(38,25): note: expanded from macro 'SIMD_AS_CHAR'

define SIMD_AS_CHAR(a) char(a)

                    ^~~~~~~

and also these:

..\CSimdImageResolutionReductorComp.cpp(141,15): error: always_inline function '_mm_mullo_epi32' requires target feature 'sse4.1', but would be inlined into function 'Calc4PixelValue' that is compiled without support for 'sse4.1' m128i r2 = _mm_mullo_epi32(_mm_and_si128(loaded2, mask), c5); ^ ..\CSimdImageResolutionReductorComp.cpp(142,15): error: always_inline function '_mm_mullo_epi32' requires target feature 'sse4.1', but would be inlined into function 'Calc4PixelValue' that is compiled without support for 'sse4.1' m128i r3 = _mm_mullo_epi32(_mm_and_si128(loaded3, mask), c10); ^ ..\CSimdImageResolutionReductorComp.cpp(143,15): error: always_inline function '_mm_mullo_epi32' requires target feature 'sse4.1', but would be inlined into function 'Calc4PixelValue' that is compiled without support for 'sse4.1' m128i r4 = _mm_mullo_epi32(_mm_and_si128(loaded4, mask), c10); ^ ..\CSimdImageResolutionReductorComp.cpp(144,15): error: always_inline function '_mm_mullo_epi32' requires target feature 'sse4.1', but would be inlined into function 'Calc4PixelValue' that is compiled without support for 'sse4.1' m128i r5 = _mm_mullo_epi32(_mm_and_si128(loaded5, mask), c5); ^

MSVC, Intel, GCC and MinGW are fine with this, although. What could be the reason and it is possible to fix it for Clang?

Hello! As I can see this bug report is linked with previous your report (https://github.com/ermig1979/Simd/issues/166). You were used the same Simd vesion in both cases. I made some fixes and they were included in release: (https://github.com/ermig1979/Simd/releases/tag/v4.9.104). Could you check are my changes fix this bug?

[ArsMasiuk]

Thank you, I'll check ASAP

unfortunately, the bug is yet here:

OK. I will try to fixed it.

I did some fixes: https://github.com/ermig1979/Simd/archive/refs/heads/master.zip Could you check?

It looks like AVX includes are not loaded. Should I maybe disable AVX support in the SimdConfig.h?

[ermig1979]

Why do your file CSimdRgbToGrayProcessorComp.cpp includes SimdMemory.h ? This is internal file of SimdLibrary. You can include in your project only SimdLib.h (or C++ header files like Simd*.hpp).

[ArsMasiuk]

ok, seems I've finally got it... one thing I had to do is to disable SSE3 support in my code. and second, add -msse4.2 instead of -msse4 to the compiler flags. thank you for your help and for the great lib :)

[ArsMasiuk]

Why do your file CSimdRgbToGrayProcessorComp.cpp includes SimdMemory.h ? This is internal file of SimdLibrary. You can include in your project only SimdLib.h (or C++ header files like Simd*.hpp).

Thats because I needed to use some defines like K16_00FF etc which are not visible by default.

[ermig1979]

There is simpler way:

__m128i K16_00FF = _mm_set1_epi16(0x00FF);

[ArsMasiuk]

There is simpler way:

__m128i K16_00FF = _mm_set1_epi16(0x00FF);

I'll try, thanks!
