Date:   Wed Feb 9 14:56:58 2022 -0800

    [COMMITTED] Fix PR aarch64/104474: ICE with vector float initializers and non-consts.

    The problem here is that the aarch64 back-end was placing const0_rtx
    into the constant vector RTL even if the mode was a floating point mode.
    The fix is instead to use CONST0_RTX and pass the mode to select the
    correct zero (either const_int or const_double).

    Committed as obvious after a bootstrap/test on aarch64-linux-gnu with
    no regressions.

    	PR target/104474

    gcc/ChangeLog:

    	* config/aarch64/aarch64.cc
    	(aarch64_sve_expand_vector_init_handle_trailing_constants):
    	Use CONST0_RTX instead of const0_rtx for the non-constant elements.

    forwprop: Enhance vec perm fed by CTOR and CTOR/CST [PR99398]

    VEC_PERM_EXPR requires the number of MASK elements must be the
    same with the number of elements in operands V0 and V1.  In
    some cases, like with Power altivec built-in function vec_perm,
    VIEW_CONVERT_EXPR has to be used to guarantee this requirement,
    but it can prevent some simplifications which don't consider
    this well.

    For the cases that the permutated operands of vector
    permutation are from two same type CTOR and CTOR, or one CTOR
    and one VECTOR CST, this patch is to enhance forwprop to look
    through intermediate VIEW_CONVERT_EXPR and further simplify
    them if possible.

    Bootstrapped/regtested on powerpc64le-linux-gnu P9,
    powerpc64-linux-gnu P8, x86_64-redhat-linux and
    aarch64-linux-gnu.

    gcc/ChangeLog:

    	PR tree-optimization/99398
    	* tree-ssa-forwprop.c (simplify_permutation): Optimize some cases
    	where the fed operands are CTOR/CST and propagated through
    	VIEW_CONVERT_EXPR.  Call vec_perm_indices::new_shrunk_vector.
    	* vec-perm-indices.c (vec_perm_indices::new_shrunk_vector): New
    	function.
    	* vec-perm-indices.h (vec_perm_indices::new_shrunk_vector): New
    	declare.

    gcc/testsuite/ChangeLog:

    	PR tree-optimization/99398
    	* gcc.target/powerpc/vec-perm-ctor-run.c: New test.
    	* gcc.target/powerpc/vec-perm-ctor.c: New test.
    	* gcc.target/powerpc/vec-perm-ctor.h: New test.
