+Subject: [PATCH] c: Fix bogus vector initialisation error [PR96377]
+
+One of the problems in this PR was that if we had:
+
+ vector_type1 array[] = { vector_value1 };
+
+process_init_element would only treat vector_value1 as initialising
+a vector_type1 if they had the same TYPE_MAIN_VARIANT. This has
+several problems:
+
+(1) It gives confusing error messages if the vector types are
+ incompatible. (Tested by gcc.dg/pr96377-1.c.)
+
+(2) It means that we reject code that should be valid with
+ -flax-vector-conversions. (Tested by gcc.dg/pr96377-2.c.)
+
+(3) On arm and aarch64 targets, it means that we reject some
+ initializers that mix Advanced SIMD and standard GNU vectors.
+ These vectors have traditionally had different TYPE_MAIN_VARIANTs
+ because they have different mangling schemes. (Tested by
+ gcc.dg/pr96377-[3-6].c.)
+
+(4) It means that we reject SVE initializers that should be valid.
+ (Tested by gcc.target/aarch64/sve/gnu_vectors_[34].c.)
+
+(5) After r11-1741-g:31427b974ed7b7dd54e2 we reject:
+
+ arm_neon_type1 array[] = { k ^ arm_neon_value1 };
+
+ because applying the binary operator to arm_neon_value1 strips
+ the "Advanced SIMD type" attributes that were added in that patch.
+ Stripping the attributes is problematic for other reasons though,
+ so that still needs to be fixed separately.
+
+g++.target/aarch64/sve/gnu_vectors_[34].C already pass.
