Help with workflow
Hi Everyone This is my first post here. I need help mapping a enjoyable workflow from GnuCOBOL to GCC. I love COBOL and with GnuCOBOL, I can compile one of my programs to intermediate C and then take the GnuCOBOL source code for the runtime and the C outputted and hop around though it using ctags. It is great to write something in COBOL and then to see how it is actually implemented in the runtime in C. I want to do the same thing with Ada. This was my first attempt: gcc -c -gnatDGL but the output wasn't really that meaningful, it was basically just my program with no ctag links into the runtime. I tried to create a little shell script : gcc -c -fdump-tree-original-raw ada83_syntax.adb gcc -c -fdump-tree-gimple-raw ada83_syntax.adb gcc -c -fdump-tree-cfg-raw ada83_syntax.adb ctags ../*.[ch] ../ada/* *.original *.gimple *.cfg gvim ../*.[ch] ../ada/* *.original *.gimple *.cfg tags I was hoping that I would catch the top level C code and that it would help. It didn't seem to. Could anyone help with what I am trying to do? Thanks for reading-Pat
Re: Help with workflow
Pat, Not sure what you are trying to do . Are you trying to generate C code from Ada? If so, can you clarify why? In other words, what is the high level problem you are trying to solve and that you'd like to achieve? Is it the ability to navigate in Ada code? If you want to generate C from Ada, GCC isn't the right tool, since GCC doesn't generate C code, it generates an intermediate representation which is then translated into assembly code directly, without ever generating C code.

GSoC 2021 project help
Hi everyone I came across the list of project ideas that were selected for GSoC 2020 and I'm interested in contributing to the project regarding the *Implementation of OMPD in GCC, libgomp, and GDB. * I was able to build GCC from source, as specified in the *Before you apply* section. Is this project going to be considered for GSoC 2021 as well? How can I get started with this project? Can I contact the mentor who is mentioned in the above project's description regarding this? Thanks, Adharsh

Hi Arnaud
Thanks for responding to my post. I am not trying to generate C but to
follow the intermediate representation into the Ada runtime.
So let's just say we had this:
*with* Ada.Text_IO;
*use* Ada.Text_IO;
*procedure* Do_Delays*is*
*begin*
Put_Line("Wait 5 seconds.");
*delay* 5.0;
Put_Line("Wait 2 seconds.");
*delay* 2.0;
Put_Line("Wait 7 seconds.");
*delay* 7.0;
Put_Line("That's all folks.");
*end* Do_Delays;
I want to follow "delay" through the intermediate representation into the Ada
runtime to see where the code actually causes a pause state to occur.
I can do this with GnuCOBOL because it compiles to C but that is not the case
here and I can't seem to figure out how to follow the code as it is being
translated through it's various stages and into the runtime.
Thanks again-Pat

Ok so you should indeed use -gnatDL and you will see these runtime calls
materialize. The syntax of the .dg files is documented in gcc/ada/sprint.ads
