Analyzing the code, this function https://github.com/etsiiull/SIMDE/blob/9809355f1c1ad4f07b845d1d5afbcbd66ed24c3e/src/core/VLIW/VLIW.ts#L78 and this other https://github.com/etsiiull/SIMDE/blob/9809355f1c1ad4f07b845d1d5afbcbd66ed24c3e/src/core/VLIW/VLIW.ts#L90 seems that are never called. Also, it seems that SIMDE web never checks dependencies statically and while running we should investigate is the hazard detector is working as intended (see https://github.com/oxcabe/SIMDE/pull/45#discussion_r1186752801)
