HeaderInclude config/or1k/or1k-opts.h mhard-div Target RejectNegative InverseMask(SOFT_DIV) Enable generation of hardware divide (l.div, l.divu) instructions. This is the default; use -msoft-div to override. msoft-div Target RejectNegative Mask(SOFT_DIV) Enable generation of binaries which use functions from libgcc to perform divide operations. The default is -mhard-div. mhard-mul Target RejectNegative InverseMask(SOFT_MUL). Enable generation of hardware multiply instructions (l.mul, l.muli) instructions. This is the default; use -msoft-mul to override. msoft-mul Target RejectNegative Mask(SOFT_MUL). Enable generation of binaries which use functions from libgcc to perform multiply operations. The default is -mhard-mul. msoft-float Target RejectNegative InverseMask(HARD_FLOAT) Enable generation of binaries which use functions from libgcc to perform floating point operations. This is the default; use -mhard-float to override. mhard-float Target RejectNegative Mask(HARD_FLOAT) Enable generation of hardware floating point instructions. The default is -msoft-float. mdouble-float Target Mask(DOUBLE_FLOAT) When -mhard-float is selected, enables generation of double-precision floating point instructions. By default functions from libgcc are used to perform double-precision floating point operations. munordered-float Target RejectNegative Mask(FP_UNORDERED) When -mhard-float is selected, enables generation of unordered floating point compare and set flag (lf.sfun*) instructions. By default functions from libgcc are used to perform unordered floating point compare and set flag operations. mcmodel= Target RejectNegative Joined Enum(or1k_cmodel_type) Var(or1k_code_model) Init(CMODEL_SMALL) Specify the code model used for accessing memory addresses. Specifying large enables generating binaries with large global offset tables. By default the value is small. Enum Name(or1k_cmodel_type) Type(enum or1k_cmodel_type) Known code model types (for use with the -mcmodel= option): EnumValue Enum(or1k_cmodel_type) String(small) Value(CMODEL_SMALL) EnumValue Enum(or1k_cmodel_type) String(large) Value(CMODEL_LARGE) mcmov Target RejectNegative Mask(CMOV) Enable generation of conditional move (l.cmov) instructions. By default the equivalent will be generated using set and branch. mror Target RejectNegative Mask(ROR) Enable generation of rotate right (l.ror) instructions. By default functions from libgcc are used to perform rotate right operations. mrori Target RejectNegative Mask(RORI) Enable generation of rotate right with immediate (l.rori) instructions. By default functions from libgcc are used to perform rotate right with immediate operations. msext Target RejectNegative Mask(SEXT) Enable generation of sign extension (l.ext*) instructions. By default memory loads are used to perform sign extension. msfimm Target RejectNegative Mask(SFIMM) Enable generation of compare and set flag with immediate (l.sf*i) instructions. By default extra instructions will be generated to store the immediate to a register first. mshftimm Target RejectNegative Mask(SHFTIMM) Enable generation of shift with immediate (l.srai, l.srli, l.slli) instructions. By default extra instructions will be generated to store the immediate to a register first.
