I'm measuring how optimization flag number affects the coverage of GCC when it is compiling some test cases. I know GCC has predefined optimization levels, such as -O1 and -O2. I also know how to obtain the list of concrete flags enabled by a predefined level by this command:
$ gcc -O2 -Q --help=optimizer

I compiled some test cases with -O2, it turns out that 440 files and 167,035 lines of GCC source code were covered.
But when I concatenated every enabled flag into a string S and replace -O2 with S when compiling the same test cases, I found only 390 files and 90,385 lines were covered.
Can someone tell me why? I suspect there is some mechanism in GCC that makes S and -O2 behave very different.

This is the menuconfig:
Can anyone please let me know what this is about and how to resolve it?
Your help will be much appreciated.
I could resolve the issue with properly setting the PATH variable. And also you can make the changes permanent by including them in .bashrc file which will be sourced on each login of the console. For example, in .bashrc include
export PATH="$PATH :path/to/bin"
Just wanted to post a question I am facing issues installing gem install pg -v '0.21.0' for 2 projects in my system which is an M1 Mac, has anyone faced issues like this
This is the error I am getting
checking for pg_config_manual.h... yes
checking for PQconnectdb() in -lpq... no
checking for PQconnectdb() in -llibpq... no
checking for PQconnectdb() in -lms/libpq... no
Can't find the PostgreSQL client library (libpq)
> *** extconf.rb failed ***
Postgres is installed via Homebrew and libpq is also installed, I tried to point to the libpq when gem pg is being installed and try and fix the problem but that is not working too attaching the mkmf log for more details on the error and FYI Postgres is installed and I can also connect to it via terminal and other software. I tried a lot of answers from stack to no avail I am pretty new to Ruby and MAC any help will be great
More info but not sure if relevant had issues installing ruby versions 2.5.0 and 2.3.6 but that is now fixed (was showing as broken earlier so purged it and installed again after manually configuring openssl#1.0 to MAC) but when it was broken both pg and bundle install worked fine for one of my project but the Ruby 2.3.6 version failed to install
EDIT 1

When i run the program i get the following error
fatal error: 'Gl/glx.h' file not found
I am attempting to run a c++ xll graphics program on my mac. I have already downloaded Xquartz and used it to run multiple graphics programs on my computer and now i am trying to figure out what i'm missing in order to get this program to run. if anybody can point me in the right direction it would be wonderful!
Thanks

Updated Make file still getting

picture of updated make file
You need to compile with the option -I/opt/X11/include and link with the options -L/opt/X11/lib -lGL -lX11.
FYI: all work can be seen in the trac repo # http://matthewh.me/scripts/browser/c/shared_library?order=name
The original post was to long. It essentially asked why my Makefiles were not finding any of the source when building from the root directory.
UPDATE:
I did discover that the paths are all relative to the root directory, regardless of where the makefiles are placed.
I have the libs building now, however I am getting an undefined reference to main when compiling the app.
I will not paste the updated makefiles, but the source tree now looks like:

The contents of main.c are:
#include <stdio.h>
#include "c_lib.h"
int main(int argc, char *argv[])
{
if (argc > 1) {
char *arg = argv[1];
printf("%s\n", arg);
}
char str[12] = "hello world\0";
printf("%s\n", str);
char *rev = reverse(str);
printf("%s\n", rev);
return 1;
}
Why can the compiler not find the main function?
UPDATE
Your fix helped get pass the undefined reference to main, however I am now getting another undefined reference:

Should there be a readable string in the .so file that indicates that reverse is in there?

You have an error in the variable setting the output file, and the next argument (main.o) is interpreted as the output instead. main.o is thus not loaded and not linked.

An error occured while installing character-encodings (0.4.1), and Bundler cannot continue.
Make sure that `gem install character-encodings -v '0.4.1'` succeeds before bundling.
Can anyone fix this? thanks!
On Ubuntu 11.10 64bit, try installing
sudo apt-get install libxml-parser-ruby
sudo apt-get install expatxxxx
(where xxxxx is versions like -dev or --dev or 1)
Even if it has not worked try this
gem install rfeedparser -- --with-cflags=\"-O2 -pipe -march=native -Wno-unused-but-set-variable\"
