This is due to the use of the "enabled" attribute in:
(define_insn "*float<SWI48:mode><MODEF:mode>2_sse"
[(set (match_operand:MODEF 0 "register_operand" "=f,x,x")
(float:MODEF
(match_operand:SWI48 1 "nonimmediate_operand" "m,r,m")))]
"SSE_FLOAT_MODE_P (<MODEF:MODE>mode) && TARGET_SSE_MATH"
"@
fild%Z1\t%1
%vcvtsi2<MODEF:ssemodesuffix><SWI48:rex64suffix>\t{%1, %d0|%d0, %1}
%vcvtsi2<MODEF:ssemodesuffix><SWI48:rex64suffix>\t{%1, %d0|%d0, %1}"
[(set_attr "type" "fmov,sseicvt,sseicvt")
(set_attr "prefix" "orig,maybe_vex,maybe_vex")
(set_attr "mode" "<MODEF:MODE>")
(set (attr "prefix_rex")
(if_then_else
(and (eq_attr "prefix" "maybe_vex")
(match_test "<SWI48:MODE>mode == DImode"))
(const_string "1")
(const_string "*")))
(set_attr "unit" "i387,*,*")
(set_attr "athlon_decode" "*,double,direct")
(set_attr "amdfam10_decode" "*,vector,double")
(set_attr "bdver1_decode" "*,double,direct")
(set_attr "fp_int_src" "true")
(set (attr "enabled")
(cond [(eq_attr "alternative" "0")
(symbol_ref "TARGET_MIX_SSE_I387
&& X87_ENABLE_FLOAT (<MODEF:MODE>mode,
<SWI48:MODE>mode)")
(eq_attr "alternative" "1")
/* ??? For sched1 we need constrain_operands to be able to
select an alternative. Leave this enabled before RA. */
(symbol_ref "TARGET_INTER_UNIT_CONVERSIONS
|| optimize_function_for_size_p (cfun)
|| !(reload_completed
|| reload_in_progress
|| lra_in_progress)")
]
(symbol_ref "true")))
])
"enabled" was really only supposed to be used to enable or disable
alternatives according to the current subtarget, rather than enable
or disable them based on the current stage in the pass pipeline
or on whether the function is being compiled for size or speed.
I have an idea for handling the size/speed thing, but we need
to fix the ??? as well.
