Here is a reduced test case courtesy of C-Reduce: typedef int a; void b() { a __attribute__((__vector_size__(8))) c{1, 1}; } Compile with `mips64el-linux-gnuabi64-g++-10 -march=loongson3a -mmsa -o test test.c` I've also attached a pre-processed copy of the original, non-reduced code. The original is at https://github.com/simd-everywhere/simde/blob/7d0e2aca9458f760d7196b94bfdcf83b2178ea24/simde/arm/neon/cmla_rot90.h#L50-L52 (SIMDE_SHUFFLE_VECTOR_ is defined at https://github.com/simd-everywhere/simde/blob/7d0e2aca9458f760d7196b94bfdcf83b2178ea24/simde/simde-common.h#L278-L281) This is with 10.2.1-6 from Debian: /usr/bin/mips64el-linux-gnuabi64-gcc-10 --version mips64el-linux-gnuabi64-gcc-10 (Debian 10.2.1-6) 10.2.1 20210110 Copyright (C) 2020 Free Software Foundation, Inc.
