The instantiation in Mips64InstrInfo.td is used for MIPS64 in ILP32 mode, as guarded by the predicate "SYM_32" and also for a submode of -LP64 where symbols are assumed to be 32 bits wide. A similar -multiclass for MIPS64 in LP64 mode is also defined: - - // lib/Target/Mips/Mips64InstrInfo.td - multiclass MipsHighestHigherHiLoRelocs<Instruction Lui, - Instruction Daddiu> { - ... - def : MipsPat<(MipsHighest (i64 tglobaladdr:$in)), - (Lui tglobaladdr:$in)>; - ... - def : MipsPat<(MipsHigher (i64 tglobaladdr:$in)), - (Daddiu ZERO_64, tglobaladdr:$in)>; - ... - def : MipsPat<(add GPR64:$hi, (MipsHigher (i64 tglobaladdr:$lo))), - (Daddiu GPR64:$hi, tglobaladdr:$lo)>; - ... - def : MipsPat<(add GPR64:$hi, (MipsHi (i64 tglobaladdr:$lo))), - (Daddiu GPR64:$hi, tglobaladdr:$lo)>; - ... - def : MipsPat<(add GPR64:$hi, (MipsLo (i64 tglobaladdr:$lo))), - (Daddiu GPR64:$hi, tglobaladdr:$lo)>; - } - -and it is instantiated twice: - - // lib/Target/Mips/Mips64InstrInfo.td - defm : MipsHighestHigherHiLoRelocs<LUi64, DADDiu>, SYM_64; - // lib/Target/Mips/MicroMips64r6InstrInfo.td - defm : MipsHighestHigherHiLoRelocs<LUi64, DADDIU_MM64R6>, SYM_64, - ISA_MICROMIPS64R6; - -These patterns are used during instruction selection to match -MipsISD::{Highest, Higher, Hi, Lo} to a specific machine instruction -and operands. +LP64 where symbols are assumed to be 32 bits wide.
