[1/3] targhooks: Extend legitimate_address_p with code_helper [PR110248]
Checks
Commit Message
Hi,
As PR110248 shows, some middle-end passes like IVOPTs can
query the target hook legitimate_address_p with some
artificially constructed rtx to determine whether some
addressing modes are supported by target for some gimple
statement. But for now the existing legitimate_address_p
only checks the given mode, it's unable to distinguish
some special cases unfortunately, for example, for LEN_LOAD
ifn on Power port, we would expand it with lxvl hardware
insn, which only supports one register to hold the address
(the other register is holding the length), that is we
don't support base (reg) + index (reg) addressing mode for
sure. But hook legitimate_address_p only considers the
given mode which would be some vector mode for LEN_LOAD
ifn, and we do support base + index addressing mode for
normal vector load and store insns, so the hook will return
true for the query unexpectedly.
This patch is to introduce one extra argument of type
code_helper for hook legitimate_address_p, it makes targets
able to handle some special case like what's described
above. The subsequent patches will show how to leverage
the new code_helper argument.
I didn't separate those target specific adjustments to
their own patches, since those changes are no function
changes. One typical change is to add one unnamed argument
with default ERROR_MARK, some ports need to include tree.h
in their {port}-protos.h since the hook is used in some
machine description files. I've cross-built a corresponding
cc1 successfully for at least one triple of each affected
target so I believe they are safe. But feel free to correct
me if separating is needed for the review of this patch.
Besides, it's bootstrapped and regtested on
x86_64-redhat-linux and powerpc64{,le}-linux-gnu.
Is it ok for trunk?
BR,
Kewen

Is defaulting the arguments in the targets necessary for
the middle-end or only for direct uses in the targets?
It looks OK in general but please give others some time to
comment.

It's only for the direct uses in target codes, the call
sites in generic code of these hooks would use the given
code_helper type variable or an explicit ERROR_MARK, they
don't require target codes to set that.
