Many AVX512 vector operations can broadcast from a scalar memory source.
This patch enables memory broadcast for FNMSUB operations.  In order to
support AVX512 memory broadcast for FNMSUB, FNMSUB builtin functions are

Fix tests that use allocators with incorrect value types · 78ed0f80

As a GNU extension we allow containers to be instantiated with
allocators that use a different value type from the container, and
automatically rebind the allocator to the correct type. This extension
is disabled in strict modes (when __STRICT_ANSI__ is defined, i.e.
-std=c++NN dialects). These testcases unintentionally rely on the
extension and so fail for strict modes.

Tests which intentionally make use of the extension will still fail in
strict dialects, but will be addressed in a later change.

rs6000: Put CR0 first in REG_ALLOC_ORDER · 273f3d4b

IRA and LRA prefer to use CR7 (which is first in REG_ALLOC_ORDER) over
CR0, although the latter often is cheaper ("x" vs. "y" constraints).
We should figure out why this is and fix it; but until that is done,
this patch makes CR0 the first allocated register: it improves the
current code, and it is required for later patches to be effective.

(It changes two testcases to no longer look at what CR field is
allocated).

lra: fix spill_hard_reg_in_range clobber check · 3664a0f1

FROM..TO range might contain NOTE_INSN_DELETED insns, for which the
corresponding entries in lra_insn_recog_data[] are NULLs.  Example from
the problematic code from PR87596:

    (note 148 154 68 7 NOTE_INSN_DELETED)

lra_insn_recog_data[] is used directly only when the insn in question
is taken from insn_bitmap, which is not the case here.  In other
situations lra_get_insn_recog_data () guarded by INSN_P () or other
stricter predicate are used.  So we need to do this here as well.

A tiny detail worth noting: I put the INSN_P () check before the
insn_bitmap check, because I believe that insn_bitmap can contain only
real insns anyway.

compiler: list indirect imports separately in export data · dbf9376f

    
    Previously when export data referred to a type that was not defined in
    a directly imported package, we would write the package name as
    additional information in the type's export data.  That approach
    required all type information to be read in order.  This patch changes
    the compiler to find all references to indirectly imported packages,
    and write them out as an indirectimport line in the import data.  This
    will permit us to read exported type data out of order.
    
    The type traversal used to find indirect imports is a little more
    complicated than necessary in preparation for later patches in this
    series.
