The scripts now allow one to pass in CC=foo. If a path is specified
it'll use that path (for instance in case you want a different version
or because in macOS /usr/bin/gcc is actually clang); otherwise the shell
will try working it out. If one does not do CC=foo then it'll default to
'cc'.
Both try.sh and compile.sh allow this and try.sh will pass CC to
compile.sh before running the commands.
The CSILENCE variable in the Makefile has been updated as well. It is
not possible to silence all warnings with clang but most of them are, at
least in macOS clang (not tested linux yet).
The alt code has been changed so that in addition to the main feature
working it will also generate ver0 and ver1 correctly; ver2 and ver3
cannot be compiled still. This is not perfect but it is progress. I will
look at this further later most likely.
Added compile.alt.sh to compile the alt code and generate the alt code
generated code. It generates it in the file name form alt.ver[0-3].c and
the code will be compiled as such.
Added try.sh to demonstrate the main (original) program. This is because
there are a lot of commands to try.
Added try.alt.sh to demonstrate the alt program (not trying the ver2 and
ver3, naturally). The rationale is the same as for try.sh.
The Makefile has been updated for these changes.
Updated .gitignore as a number of new files will be created when running
compile.alt.sh.
The bugs.md has been updated as there has been some progress made. The
hint was removed at this time as it's not applicable now; the problem of
main() args not being allowed is no longer true. However the status line
has not been updated because the root of the problem is this. There are
currently no hints because I do not have any yet.
The thanks file has also been updated for the new scripts as well as the
situation being changed.
Unfortunately the fix to let the main program compile with clang even
breaks some versions generated (see compile.sh) in syntax error so even
gcc cannot compile those. Therefore it's now alt code. The alt version
will compile with clang and the main feature of the program will work
but the program cannot generate every version of the program.
The bugs.md and thanks-for-fixes.md have been updated along with the
README.md.
In the README.md there is a different heading level for the alt code
sections to compare to another as we try and figure out what heading
levels to use.
I changed the delay to 0 in the compile.sh script but one can set it to
another value if they like.
This entry will have to be worked on more at another time.
I have tried to make the README.md file less cluttered wrt the clang
defects and instead just show how to use the entry, referring to the
bugs.md for those who need to know.
Added script compile.sh which generates the files and tries to compile
them. The script sleeps (by default approximately 1 second) in between
commands but this can be changed to another value (including 0). One can
also change the compiler path in case their compiler is clang or in the
case of macOS gcc IS clang. The README.md refers to this and gives
examples.
The bugs.md and the thanks-for-fixes.md files have been updated for
these changes and additions.
For those who do not know of the clang defects it is discussed in the
bugs.md and unfortunately for this entry there might be little that can
be done. I haven't tried to understand the entry deeply and maybe doing
so would give some ideas for fixes (beyond what I already did which lets
the main program compile with clang - or at least versions that allow a
fourth arg to main()) but this seems less important for now.
