Bug ID: 405458 Summary: MIPS mkFormVEC arguments swapped? Product: valgrind Version: unspecified Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: vex Assignee: jsew...@acm.org Reporter: m...@klomp.org CC: mips3...@gmail.com Target Milestone: --- The following function in VEX/priv/host_mips_defs.c static UChar *mkFormVEC(UChar *p, UInt op, UInt ws, UInt wt, UInt wd) { UInt theInstr; vassert(op < 0x20); vassert(wt < 0x20); vassert(ws < 0x20); vassert(wd < 0x20); theInstr = OPC_MSA | (op << 21) | (wt << 16) | (ws << 11) | (wd << 6) | 0x1E; return emit32(p, theInstr); } And the use in: case Msa_VEC: { UInt v_wt = qregEnc(i->Min.MsaVec.wt); UInt v_ws = qregEnc(i->Min.MsaVec.ws); UInt v_wd = qregEnc(i->Min.MsaVec.wd); p = mkFormVEC(p, i->Min.MsaVec.op, v_wt, v_ws, v_wd); goto done; } Looks like they swap the arguments wt and ws. -- You are receiving this mail because: You are watching all bug changes.
