    [mips] Fix code generation bug in handling of immediates · abd9610e
    danno authored
    When testing turning --verify-csa off to generate better code for builtins, mips
    started failing mksnapshot due to an assert in instruction-selection-mips.cc's
    VisitBinop routine, which creates a buffer to hold InstructionOperand of size 4
    that would be overflowed. This fix is somewhat speculative, assuming that either
    the LHS or the RHS operand of a mips binary op can be an immediate (as opposed
    to the current code which seems to have a code path where both the left and
    right operands are added, leading to the buffer overflow). With this fix, the
    assert doesn't fire and all of the mips tests run through successfully in debug
    mode.
