PDP-11 assembler options

This is a proposal. As far as I know, these options should accurately describe the features found in different PDP-11 models and CPUs. Please contact me if you find any errors.

PDP-11-specific options in the GNU assembler.

Machine model options:

(FPP?) -m[[pdp]11/]60 Same as -mkd11k. -m[[pdp]11/]53 -m[[pdp]11/]73 -m[[pdp]11/]83 -m[[pdp]11/]84 -m[[pdp]11/]93 -m[[pdp]11/]94 Same as -mj11.

CPU model options:

-m[k]a[-]11* KA11 CPU. Base line instruction set only. -m[k]b[-]11* KB11 CPU. Enable full EIS and SPL. Same as -meis -mspl. (FPP?) -m[k]d[-]11[-]a KD11-A CPU. Enable limited EIS. Same as -mlimited-eis. (EIS?) -m[k]d[-]11[-]b -m[k]d[-]11[-]d KD11-B or KD11-D CPU. Base line instruction set only. -m[k]d[-]11[-]e KD11-E CPU. Enable full EIS, MTPS, and MFPS. Same as -meis -mmxps. (FPP?) -m[k]d[-]11[-]f -m[k]d[-]11[-]h -m[k]d[-]11[-]q KD11-F, KD11-H, or KD11-Q CPU. Enable limited EIS, MTPS, and MFPS. Same as -mlimited-eis -mmxps. (EIS?) -m[k]d[-]11[-]k KD11-K CPU. Enable full EIS, MTPS, MFPS, LDUB, MED, XFC, and MFPT. Same as -meis -mmxps -mmfpt -mucode. (FPP?) -m[k]d[-]11[-]z KD11-Z CPU. Enable full EIS, MTPS, MFPS, MFPT, SPL, and CSM. Same as -meis -mmxps -mmfpt -mspl -mcsm. (FPP?) -m[kd]f[-]11* F11 CPU. Enable full EIS, MFPS, MTPS, and MFPT. Same as -meis -mmxps -mmfpt. (FPP?) -m[kd]j[-]11* J11 CPU. Enable full EIS, MTPS, MFPS, MFPT, SPL, CSM, TSTSET, and WRTLCK. Same as -meis -mmxps -mmfpt -mspl -mcsm -mmultiproc. (FPP?) -m[kx]t[-]11* T11 CPU. Enable limited EIS, MTPS, and MFPS. Same as -mlimited-eis -mmxps.

Instruction set features:

-m(no-)cis Enable (disable) commersial instruction set. -m(no-)eis Enable (disable) full extended instruction set. -mlimited-eis Enable limited extended instruction set. -m(no-)fis Enable (disable) KEV11 floating-point instruction set. -m(no-)fpp -m(no-)fpu Enable (disable) FP-11 floating-point instructions. -m(no-)spl Enable (disable) SPL instruction. -m(no-)csm Enable (disable) CSM instruction. -m(no-)mxps Enable (disable) MFPS and MTPS instructions. -m(no-)mfpt Enable (disable) MFPT instruction. -m(no-)ucode Enable (disable) LDUB, MED, and XFC instructions. -m(no-)multiproc Enable (disable) TSTSET and WRTLCK instructions. -mall-extensions Enable all instruction set extensions. Same as -mcis -meis -mfis -mfpp -mspl -mcsm -mmxps -mmfpt -mucode -mmultiproc. -mno-extensions Disable all instruction set extensions. Same as -mno-cis -mno-eis -mno-fis -mno-fpp -mno-spl -mno-csm -mno-mxps -mno-mfpt -mno-ucode -mno-multiproc. -pic Indicates PIC.

Unix and 2.11BSD assembler compatibility options:

Not really necessary?

-u Treat all undefined symbols in the assembly as external globals. -V Produce an object suitable for loading into an automatic text overlaid program.
