tests/checkasm: add overflow test for hevc_add_res
Add overflow test for hevc_add_res when int16_t coeff = -32768. The result of C is good, while ASM is not. To verify: make fate-checkasm-hevc_add_res ffmpeg/tests/checkasm/checkasm --test=hevc_add_res ./checkasm --test=hevc_add_res checkasm: using random seed 679391863 MMXEXT: hevc_add_res_4x4_8_mmxext (hevc_add_res.c:69) - hevc_add_res.add_residual [FAILED] SSE2: hevc_add_res_8x8_8_sse2 (hevc_add_res.c:69) hevc_add_res_16x16_8_sse2 (hevc_add_res.c:69) hevc_add_res_32x32_8_sse2 (hevc_add_res.c:69) - hevc_add_res.add_residual [FAILED] AVX: hevc_add_res_8x8_8_avx (hevc_add_res.c:69) hevc_add_res_16x16_8_avx (hevc_add_res.c:69) hevc_add_res_32x32_8_avx (hevc_add_res.c:69) - hevc_add_res.add_residual [FAILED] AVX2: hevc_add_res_32x32_8_avx2 (hevc_add_res.c:69) - hevc_add_res.add_residual [FAILED] checkasm: 8 of 14 tests have failed Signed-off-by:Xu Guangxin <guangxin.xu@intel.com> Signed-off-by:
