So all that generating machine code or byte code is, is really adding items to an array of structs. Of course, if you want to generate Intel machine code its a little more complicated, because instructions can be different size, so you can't use a classic array, but you can write the...
I have to write an assembly function as below: asm volatile void OSPendSVException (void){ add sp, sp, #(9*4) pop {pc} bx lr} __asm void OSPendSVException1(void){ add sp, sp, #(9*4) pop {pc} bx lr} __asm__ void OSPendSVException2(void){ add sp, sp, #(9*4) p...
With Arm Compiler 5:This compiler knows the __svc keyword, which makes it simple to define a SVC function: void__svc(0) EnablePrivilegedMode(void) ; With Arm Compiler 6:With this compiler inline assembler needs to be used to generate something equivalent: ...
(used in some gaming consoles). is it possible to write portable code in assembler? writing portable code in assembler is challenging because it is highly dependent on the specific hardware architecture. however, some cross-platform assemblers and abstractions exist to aid in portability across ...
