Target RejectNegative Report InverseMask(M340)
Generate code for the M*Core M210

Target RejectNegative Report Mask(M340)
Generate code for the M*Core M340

Target Report Mask(OVERALIGN_FUNC)
Force functions to be aligned to a 4 byte boundary.

Target RejectNegative Report InverseMask(LITTLE_END)
Generate big-endian code.

Target Report Mask(CG_DATA)
Emit call graph information.

Target Report Mask(DIV)
Use the divide instruction.

Target Report Mask(HARDLIT)
Inline constants if it can be done in 2 insns or less.

Target RejectNegative Report Mask(LITTLE_END)
Generate little-endian code.

; Not used by the compiler proper.
Target RejectNegative
Assume that run-time support has been provided, so omit -lsim from the linker command line.

Target Report Mask(RELAX_IMM)
Use arbitrary sized immediates in bit operations.

Target Report Mask(SLOW_BYTES)
Prefer word accesses over byte accesses.

; Maximum size we are allowed to grow the stack in a single operation.
; If we want more, we must do it in increments of at most this size.
; If this value is 0, we don't check at all.
Target RejectNegative Joined UInteger Var(mcore_stack_increment) Init(STACK_UNITS_MAXSTEP)
Set the maximum amount for a single stack increment operation.

Target Report Mask(W_FIELD)
Always treat bitfields as int-sized.
