# RawAsmParser → StinkyAsmEmitter round-trip for hwreg() operand syntax.
# Verifies that:
# - All three forms (id only / id+offset / id+offset+size) parse cleanly.
# - Defaults (offset=0, size=32) collapse on emit and lock in baseline stability.
# - Symbolic HW_REG_* id resolves via the per-arch DEF_HWREG table.
# - s_setreg* (dest=hwreg) and s_getreg_b32 (src=hwreg) slot directions preserved.

test_start:
    # id only — default offset=0/size=32, both suppressed on emit.
    s_getreg_b32 s0, hwreg(1)

    # id + offset only — default size=32 suppressed on emit.
    s_getreg_b32 s1, hwreg(2,4)

    # full triple, all explicit.

    # SCHED_MODE numeric id.
    s_setreg_IMM32_b32 hwreg(26,0,2), 2

    # Symbolic id resolves through nameToId (HW_REG_WAVE_MODE -> 1 on gfx1250).
