Implies -mgpOPT    -O1	  Same as -O, mips compatibility    -O2   Implies -O -fomit-frame-pointer -fstrength-reduce    -O3   Implies -O2 + -finline-functions    -mG0 -mG1 -mG2          Construct a size to be passed to GCC for Data / Sdata selection.          Value is ( (i=G0 + 2 G1 + 4 G2) , (i < 6) ? ( 1<<i) :(1 <<(i+3)))          Same value should be passed to as + ld using -G.  Use -G instead	  since it is now supported.	  Default = -mG1 -mG0 (Value = 8).    -G32  Implies -G 32 -mG2 -mnG1 -mG0.    -bestGnum          Pass -bestGnum flag to ld. This helps setting best value for          the -G parameter.    -ZSYSV  for RISC-OS: use the System V environment    -ZBSD43 for RISC-OS: use the BSD 4.3  environment----------------------------------------------------------------------*//* Suppression of libg.a when debugging */#define NO_LIBG/* Switch  Recognition by gcc.c   */#ifdef SWITCH_TAKES_ARG#undef SWITCH_TAKES_ARG#endif#define SWITCH_TAKES_ARG(CHAR)      \  ((CHAR) == 'D' || (CHAR) == 'U' || (CHAR) == 'o' \   || (CHAR) == 'e' || (CHAR) == 'T' || (CHAR) == 'u' \   || (CHAR) == 'I' || (CHAR) == 'Y' || (CHAR) == 'm' \   || (CHAR) == 'L' || (CHAR) == 'i' || (CHAR) == 'A' \   || (CHAR) == 'G')/* Process -mGxx switches  */extern void overide_options ();#define OVERRIDE_OPTIONS overide_options ()/* Names to predefine in the preprocessor for this target machine.  */#ifndef CPP_PREDEFINES#define CPP_PREDEFINES "-Dmips -Dunix -Dhost_mips -DMIPSEB -DR3000 -DLANGUAGE_C"#endif/* Extra switches sometimes passed to the assembler.  */#ifndef ASM_SPEC#ifndef OSF_OS			/* normal MIPS system */#ifndef DECSTATION		/* big endian MIPS (MIPS, SGI) */#ifndef SGI_TARGET		/* not Silicon Graphics (ie, MIPSco) */#define ASM_SPEC	"%{!mrnames:-nocpp}				\			 %{!mgas:					\				%{pipe: %e-pipe is not supported.}	\				%{EB} %{!EB:-EB}			\				%{EL: %e-EL not supported}		\				%{O:-O2} %{O1:-O2} %{O2:-O2} %{O3:-O3}	\				%{g} %{g1} %{g2} %{g3} %{g0}}		\			 %{G*}						\			 %{!G:%{!G32:	%{mpic:-G 0} %{pic:-G 0}	\					%{mgas:-G 0}			\					%{!pic:%{!mpic:%{!mgas:-G 8}}}}	\				%{G32: -G 32}}				\			 %{v} %{K}"#else				/* Silicon Graphics */#define ASM_SPEC	"%{!mrnames:-nocpp}				\			 %{!mgas:					\				%{pipe: %e-pipe is not supported.}	\				%{O:-O2} %{O1:-O2} %{O2:-O2} %{O3:-O3}	\				%{g} %{g1} %{g2} %{g3} %{g0}}		\			 %{G*}						\			 %{!G:%{!G32:	%{mpic:-G 0} %{pic:-G 0}	\					%{mgas:-G 0}			\					%{!pic:%{!mpic:%{!mgas:-G 8}}}}	\				%{G32: -G 32}}				\			 %{v} %{K}"#endif				/* Silicon Graphics */#else				/* Ultrix Decstation (little endian) */#define ASM_SPEC	"%{!mrnames:-nocpp}				\			 %{!mgas:					\				%{pipe:%e:-pipe not supported}		\				%{EL} %{!EL:-EL}			\				%{EB: %e-EB not supported}		\				%{O:-O2} %{O1:-O2} %{O2:-O2} %{O3:-O3}	\				%{g} %{g1} %{g2} %{g3} %{g0}}		\			 %{G*}						\			 %{!G:%{!G32:	%{mpic:-G 0} %{pic:-G 0}	\					%{mgas:-G 0}			\					%{!pic:%{!mpic:%{!mgas:-G 8}}}}	\				%{G32: -G 32}}				\			 %{v} %{K}"#endif				/* DECstation running Ultrix */#else				/* OSF/1 of some sort */#ifndef DECSTATION				/* Big endian MIPS running OSF/1 */#define ASM_SPEC	"%{mmips-as:					\				%{pipe:%e:-pipe not supported}		\				%{EB} %{!EB:-EB}			\				%{EL: %e-EL not supported}		\				%{!mrnames:-nocpp}			\				%{O:-O2} %{O1:-O2} %{O2:-O2} %{O3:-O3}	\				%{g} %{g1} %{g2} %{g3} %{g0}		\				%{v} %{K}}				\			 %{G*}						\			 %{!G:%{!G32:	%{mpic:-G 0} %{pic:-G 0}	\					%{!mmips-as:-G 0}		\					%{!pic:%{!mpic:%{mmips-as:-G 8}}}} \				%{G32: -G 32}}"#else				/* Little endian OSF/1 Decstation */#define ASM_SPEC	"%{mmips-as:					\				%{pipe:%e:-pipe not supported}		\				%{EL} %{!EL:-EL}			\				%{EB: %e-EB not supported}		\				%{!mrnames:-nocpp}			\				%{O:-O2} %{O1:-O2} %{O2:-O2} %{O3:-O3}	\				%{g} %{g1} %{g2} %{g3} %{g0}		\				%{v} %{K}}				\			 %{G*}						\			 %{!G:%{!G32:	%{mpic:-G 0} %{pic:-G 0}	\					%{!mmips-as:-G 0}		\					%{!pic:%{!mpic:%{mmips-as:-G 8}}}} \				%{G32: -G 32}}"#endif				/* little endian OSF/1 DECstation */#endif				/* OSF/1 */#endif				/* ASM_SPEC *//* Redefinition of libraries used.
