Subject: [PATCH 29/30] 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.
