msoft-float
Target Report RejectNegative Mask(SOFT_FLOAT)
Use software emulation for floating point (default).
mhard-float
Target Report RejectNegative InverseMask(SOFT_FLOAT, HARD_FLOAT)
Use hardware floating point instructions.
msmall-divides
Target Mask(SMALL_DIVIDES)
Use table lookup optimization for small signed integer divisions.
mcpu=
Target RejectNegative Joined Var(microblaze_select_cpu)
-mcpu=PROCESSOR Use features of and schedule code for given CPU.
mmemcpy
Target Mask(MEMCPY)
Don't optimize block moves, use memcpy.
mbig-endian
Target Report RejectNegative InverseMask(LITTLE_ENDIAN)
Assume target CPU is configured as big endian.
mlittle-endian
Target Report RejectNegative Mask(LITTLE_ENDIAN)
Assume target CPU is configured as little endian.
mxl-soft-mul
Target Mask(SOFT_MUL)
Use the soft multiply emulation (default).
mxl-reorder
Target Var(TARGET_REORDER) Init(2)
Use reorder instructions (swap and byte reversed load/store) (default).
mxl-soft-div
Target Mask(SOFT_DIV)
Use the software emulation for divides (default).
mxl-barrel-shift
Target Mask(BARREL_SHIFT)
Use the hardware barrel shifter instead of emulation.
mxl-pattern-compare
Target Mask(PATTERN_COMPARE)
Use pattern compare instructions.
