Cannot optimize complex ge_u 0 out #7556
Description
Given the following code:
(module
(type $0 (func))
(type $1 (func (param i32 i32) (result i32)))
(type $2 (func (result i32)))
(type $3 (func (param i32) (result i32)))
(import "External" "external_function" (func $external_function (type $0)))
(func $_start (type $3) (param $0 i32) (result i32)
(local $1 i32) (local $2 i32)
i32.const 0
i32.load
local.set $2
local.get $1
i32.const 0
call $foo
local.set $1
local.get $1
local.get $2
i32.le_u
if (result i32)
i32.const 0
else
call $external_function
i32.const 1
end)
(func $foo (type $1) (param $0 i32) (param $1 i32) (result i32)
i32.const 0
i32.const 0
i32.store
i32.const 0)
(memory $0 258 258)
(export "_start" (func $_start)))wasm-opt (e6d02fa) -all -O3 cannot optimize the
(i32.ge_u
(i32.load
(i32.const 0)
)
(block (result i32)
(i32.store
(i32.const 0)
(i32.const 0)
)
(i32.const 0)
)
)
to one (while -all -O2 can)
It is already discussed in #7455 (complex lt_u 0). in contrast, this is complex ge_u 0. So fix this the way as before.
