change lab-1i to iterative version |
change qemu script in Makefile... * add while loop to run from 1 to 50 * after 47, it exceeds 32-bit integer's range, overflow * add three more var for calculating the correct answer * use cut to get the program's output and compare with the correct answer * if the ans is wrong, it will output the correct answer
My loop start with 3, so there will be a bug if I didn't add exception.
Move lab-1, lab-1i's Makefile to ../make_fib.mk And include the file
reduce registers and instruction sets
Core registers and AAPCS usage * R0 ~ R3: Arguments * R4 ~ R8, R10, R11: Variable register * R9: Platform register * R12: IP (The Intra-Procedure-call scratch register) * R13: SP (The Stack Pointer) * R14: LR (The Link Register) * R15: PC (The Program Counter)
…alysis.
1. use `make qemu` to analysis, the output is 'analysis.txt'
2. after arrange the analysis file use gnuplot to generate the chart
(the command is in 'gplot_cmd.txt' file)

use recursive to do lab-1 -> fab(x)
another fast version of recursive to do lab-1i -> fab(x,first,second)
