Variable
enum or1k_delay or1k_delay_selected = OR1K_DELAY_DEFAULT

mdelay
Target RejectNegative Negative(mno-delay) Var(or1k_delay_selected, OR1K_DELAY_ON)
Assume branches and jumps have a delay slot

mno-delay
Target RejectNegative Negative(mcompat-delay) Var(or1k_delay_selected, OR1K_DELAY_OFF)
Assume branches and jumps do not have a delay slot

mcompat-delay
Target RejectNegative Negative(mdelay) Var(or1k_delay_selected, OR1K_DELAY_COMPAT)
Assume branches and jumps have a delay slot, but fill them with nops

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
Target Report RejectNegative Mask(DOUBLE_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

mror
Target Mask(MASK_ROR)
Emit ROR instructions

mboard=
Target RejectNegative Joined
Link with libgloss configuration suitable for this board

mnewlib
Target Report RejectNegative
Compile for the Linux/Gnu/newlib based toolchain

;; 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)

mredzone=
Target RejectNegative Joined UInteger Var(or1k_redzone) Init(128)
Set the size of the stack below sp that is assumed to be safe from interrupts.
