mhard-float
Target RejectNegative Mask(HARD_FLOAT)
Use hardware floating point
 
msoft-float
Target RejectNegative InverseMask(HARD_FLOAT)
Do not use hardware floating point
 
mdouble-float

Allow hardware floating-point instructions to cover both 32-bit and 64-bit operations
 
mhard-div
Target RejectNegative Mask(HARD_DIV)
Use hardware division
 
msoft-div
Target RejectNegative InverseMask(HARD_DIV)
Do not use hardware division
 
mhard-mul
Target RejectNegative Mask(HARD_MUL)
Use hardware multiplication
 
msoft-mul
Target RejectNegative InverseMask(HARD_MUL)
Do not use hardware multiplication
 
msext
Target Mask(MASK_SEXT)
Use sign-extending instructions
 
mcmov
Target Mask(MASK_CMOV)
Use conditional move instructions
 
mlogue
Target Mask(SCHED_LOGUE)
Schedule prologue/epilogue
 
mror
Target Mask(MASK_ROR)
Emit ROR instructions
 
mor32-newlib
Target RejectNegative
Link with the OR32 newlib library
 
mor32-newlib-uart
Target RejectNegative
Link with the OR32 newlib UART library
 
;; provide struct padding as in previous releases.
;; Note that this will only affect STRUCTURE_SIZE_BOUNDARY, in particular
;; make 2 byte structs 4-byte alignned and sized.
;; We still use ROUND_TYPE_ALIGN to increase alignment of larger structs.
mpadstruct
Target Report RejectNegative Mask(PADSTRUCT)
Make structs a multiple of 4 bytes (warning: ABI altered)
