loading constant 0x739290001LL in rv32 can be done with three instructions
output:
li a1, 7
lui a1, 234128
addi a1, a1, 1
Similarly, loading 0x839290001LL in rv32 can be done within three instructions
expected output:
li a1, 8
lui a1, 234128
addi a1, a1, 1
However, riscv_build_integer does not handle this case well and makes a wrong prediction about the number of instructions needed and then the constant is forced to put in the memory via riscv_const_insns and emit_move_insn.
real output:
lui a4,%hi(.LC0)
lw a2,%lo(.LC0)(a4)
lw a3,%lo(.LC0+4)(a4)
.LC0:
