Checkin Comment was: Optimized support for 32x32 => 64bit multiplications on ARM
This code uses UMULL and SMULL to perform the multiplications, which take two 32bit source registers and two 32bit destination registers. ... umull is not supported by cortex-m0 chips ... system.inc(1770,8) Warning: Implicit string type conversion from "RawByteString" to "UnicodeString" /Users/ring/devel/fpc/rtl/units/arm-embedded/system.s: Assembler messages: /Users/ring/devel/fpc/rtl/units/arm-embedded/system.s:3564: Error: selected processor does not support Thumb mode `umull r0,r1,r0,r1' /Users/ring/devel/fpc/rtl/units/arm-embedded/system.s:3570: Error: selected processor does not support Thumb mode `umull r0,r1,r0,r1' /Users/ring/devel/fpc/rtl/units/arm-embedded/system.s:3576: Error: selected processor does not support Thumb mode `umull r1,r0,r0,r1' /Users/ring/devel/fpc/rtl/units/arm-embedded/system.s:3582: Error: selected processor does not support Thumb mode `umull r0,r1,r0,r1' /Users/ring/devel/fpc/rtl/units/arm-embedded/system.s:44407: Error: selected processor does not support Thumb mode `umull r0,r2,r1,r0' /Users/ring/devel/fpc/rtl/units/arm-embedded/system.s:44417: Error: selected processor does not support Thumb mode `umull r0,r2,r0,r1' /Users/ring/devel/fpc/rtl/units/arm-embedded/system.s:44427: Error: selected processor does not support Thumb mode `umull r1,r0,r0,r1' /Users/ring/devel/fpc/rtl/units/arm-embedded/system.s:44435: Error: selected processor does not support Thumb mode `umull r0,r2,r0,r1' /Users/ring/devel/fpc/rtl/units/arm-embedded/system.s:44582: Error: selected processor does not support Thumb mode `umull r0,r1,r1,r0' system.pp(257) Error: Error while assembling exitcode 1 system.pp(257) Fatal: There were 2 errors compiling module, stopping F
