[Tinycc-devel] I want to add more info with -v option

[Christian Jullien]

Hi,

 

More and more users complain with 0.9.27 bugs which are solved by mob.

They often tell us they are using ./tcc –v => 0.9.27 which is meaningless as 0.9.27 is anything form last >3y old official 0.9.27 to mob.

 

To improve this, I would like to add the git last date (or anything that can easily identify the source code version used to compile tcc).

 

./tcc –v

jullien@sims4:~/tinycc $ ./tcc -v

tcc version 0.9.27 (ARM eabihf Linux - git version Thu Mar 18 22:54:24 2021)

 

When tcc is compiled from a tarball (w.o. git info) it will tell:

jullien@sims4:~/tinycc $ ./tcc -v

tcc version 0.9.27 (ARM eabihf Linux - unknown git version)

 

Can I push this patch?
