Early stages of project

 I initially set up and built the current version of GCC on the aarch64-3 server that is provided. I started the build and it took at least an hour to fully compile. I limited the enabled languages to strictly C and C++ as I am most comfortable in these languages and to reduce the complexity of the project. The two files that control compilation passes are passes.cc, and tree-pass.h


/* Description of GIMPLE pass.  */

class gimple_opt_pass : public opt_pass

{

protected:

  gimple_opt_pass (const pass_data& data, gcc::context *ctxt)

    : opt_pass (data, ctxt)

  {

  }

};


/* Description of RTL pass.  */

class rtl_opt_pass : public opt_pass

{

protected:

  rtl_opt_pass (const pass_data& data, gcc::context *ctxt)

    : opt_pass (data, ctxt)

  {

  }

}


I did some reading and research on gimple passes and learned that they help optimize code and makes transformation at a high level before going to lower representations.

Building GCC again on aarch64-002

 Unfortunately the server I used to build gcc originally was aarch64-003 but that was shut down so I have to go through the process again on 002. The build time on the aarch64-002 server took 1 hour and 55 minutes approximately, I initially used time in my build command but I accidentally missed the information so I had to use stat build.log and find the duration of the build time by subtracting the final modification from the birth of the build.log file.

Project Stage 2: Testing

Image
 To test my custom pass I first extracted the spo600-test-clone files into my gcc-test-001 directory and simply compiled and ran the program with -fdump-tree-ctyler. I ran it on the vol1.c file, the contents of vol1.c are as following: [dpark39@aarch64-002 test-clone]$ cat vol1.c // vol1.c - fixed-point volume scaling algorithm // Chris Tyler 2017.11.29-2021.11.16 - Licensed under GPLv3. // For the Seneca College SPO600 Course #include <stdlib.h> #include <stdio.h> #include <stdint.h> #include <stdbool.h> #include "vol.h" int16_t scale_sample(int16_t sample, int volume) {         return ((((int32_t) sample) * ((int32_t) (32767 * volume / 100) <<1) ) >> 16); } int main() {         int             x;         int             ttl=0; // ---- Create in[] and out[] arrays         int16_t*    ...
