+Subject: [PATCH] lra: Avoid cycling on certain subreg reloads [PR96796]
+
+This PR is about LRA cycling for a reload of the form:
+
+----------------------------------------------------------------------------
+Changing pseudo 196 in operand 1 of insn 103 on equiv [r105:DI*0x8+r140:DI]
+      Creating newreg=287, assigning class ALL_REGS to slow/invalid mem r287
+      Creating newreg=288, assigning class ALL_REGS to slow/invalid mem r288
+  103: r203:SI=r288:SI<<0x1+r196:DI#0
+      REG_DEAD r196:DI
+    Inserting slow/invalid mem reload before:
+  316: r287:DI=[r105:DI*0x8+r140:DI]
+  317: r288:SI=r287:DI#0
+----------------------------------------------------------------------------
+
+The problem is with r287.  We rightly give it a broad starting class of
+POINTER_AND_FP_REGS (reduced from ALL_REGS by preferred_reload_class).
+However, we never make forward progress towards narrowing it down to
+a specific choice of class (POINTER_REGS or FP_REGS).
+
+I think in practice we rely on two things to narrow a reload pseudo's
+class down to a specific choice:
+
+(1) a restricted class is specified when the pseudo is created
+
+    This happens for input address reloads, where the class is taken
+    from the target's chosen base register class.  It also happens
+    for simple REG reloads, where the class is taken from the chosen
+    alternative's constraints.
+
+(2) uses of the reload pseudo as a direct input operand
+
+    In this case get_reload_reg tries to reuse the existing register
+    and narrow its class, instead of creating a new reload pseudo.
+
+However, neither occurs here.  As described above, r287 rightly
+starts out with a wide choice of class, ultimately derived from
+ALL_REGS, so we don't get (1).  And as the comments in the PR
+explain, r287 is never used as an input reload, only the subreg is,
+so we don't get (2):
+
+----------------------------------------------------------------------------
+         Choosing alt 13 in insn 317:  (0) r  (1) w {*movsi_aarch64}
+      Creating newreg=291, assigning class FP_REGS to r291
+  317: r288:SI=r291:SI
+    Inserting insn reload before:
+  320: r291:SI=r287:DI#0
+----------------------------------------------------------------------------
+
+IMO, in this case we should rely on the reload of r316 to narrow
+down the class of r278.  Currently we do:
+
+----------------------------------------------------------------------------
+         Choosing alt 7 in insn 316:  (0) r  (1) m {*movdi_aarch64}
+      Creating newreg=289 from oldreg=287, assigning class GENERAL_REGS to r289
+  316: r289:DI=[r105:DI*0x8+r140:DI]
+    Inserting insn reload after:
+  318: r287:DI=r289:DI
+---------------------------------------------------
+
+i.e. we create a new pseudo register r289 and give *that* pseudo
+GENERAL_REGS instead.  This is because get_reload_reg only narrows
+down the existing class for OP_IN and OP_INOUT, not OP_OUT.
+
+But if we have a reload pseudo in a reload instruction and have chosen
+a specific class for the reload pseudo, I think we should simply install
+it for OP_OUT reloads too, if the class is a subset of the existing class.
+We will need to pick such a register whatever happens (for r289 in the
+example above).  And as explained in the PR, doing this actually avoids
+an unnecessary move via the FP registers too.
+
+The patch is quite aggressive in that it does this for all reload
+pseudos in all reload instructions.  I wondered about reusing the
+condition for a reload move in in_class_p:
+
+          INSN_UID (curr_insn) >= new_insn_uid_start
+          && curr_insn_set != NULL
+          && ((OBJECT_P (SET_SRC (curr_insn_set))
+               && ! CONSTANT_P (SET_SRC (curr_insn_set)))
+              || (GET_CODE (SET_SRC (curr_insn_set)) == SUBREG
+                  && OBJECT_P (SUBREG_REG (SET_SRC (curr_insn_set)))
+                  && ! CONSTANT_P (SUBREG_REG (SET_SRC (curr_insn_set)))))))
+
+but I can't really justify that on first principles.  I think we
+should apply the rule consistently until we have a specific reason
+for doing otherwise.
