compiler: add backend type conversion

    Tweak Interface_field_reference_expression::do_get_backend to apply an
    additional backend type conversion to the returned result.  This is
    needed due to the fact that the top level type of the expression is a
    function descriptor, however the value being manufactured is a pointer
    to <thunk-descriptor, value> struct.

compiler: track placeholder pointer types for conversion

    We recently started walking through the hash table of pointer types to
    finalize them.  Unfortunately it is possible to create a new pointer
    type while finalizing an existing one (test case: test/fixedbugs/issue5291)
    and that breaks the iteration.  So, instead, keep a list of
    placeholder pointer types, and iterate through them while permitting
    the list to be extended as we go.

compiler: use a single temporary for calls with multiple results

    For calls that return multiple results we used to create a temporary
    of struct type to hold the results, and also create a separate
    temporary for each result.  Then the call expression would copy each
    result out of the struct to the temporary, and Call_result_expression
    would refer to the desired temporary.

    Simplify this to just use a single temporary of struct type, and
    change Call_result_expression to fetch a field of the struct.

    This may reduce some incorrect tree sharing in the backend code.

[PATCH][AArch64] Fix missing optimization for CMP+AND

During combine GCC tries to merge CMP (with zero) and AND into a TST. However,
in cases where an ANDS operand is not compatible, this was being missed. Adding
a define_split where this operand was moved to a register seems to help out.

[Patch (preapproved)] Guard Copy Header pass on

While answering a user question on the equivalence of

spotted one case which broke the equivalence. pass_ch::process_loop_p

-ftree-vectorize, but not for -ftree-loop-vectorize/-ftree-slp-vectorize.

[rs6000] Avoid rotates of floating-point modes

The little-endian VSX code uses rotates to swap the two 64-bit halves of
128-bit scalar modes.  This is fine for TImode and V1TImode, but it
isn't really valid to use RTL rotates on floating-point modes like
KFmode and TFmode, and doing that triggered an assert added by the

x86: Properly check saved register CFA offset

X86 prologue saves register at CFA offset.  Since its location on stack
is computed as CFA - its CFA_OFFSET, CFA_OFFSET points the end of the

compiler: clean up unresolved placeholders for pointer types

    Add a new helper routine Type::finish_pointer_types that walks through
    the pointer type cache and looks for placeholder types that may have
    been created at some point before conversion of named types, and
    invokes Type::finish_backend() on said placeholders.  This is needed
    to handle cases where the compiler manufactures a pointer type as part
    of lowering, then a placeholder is created for it due to a call to
    Type::backend_type_size(), but there is no explicit reference to the
    type in user code.
