Good evening,
This patch removes the following static variables from 'final.cc':
override_filename, override_linenum,
override_columnnum, override_discriminator
You will note by browsing the trunk's code that override_filename is
never set, and therefore the only usage of those variables is never
triggered. They can therefore be safely removed.
For context, they were added in [1,2] to track code location for
some inline functions. It's the same patch which implemented
tree_nonartificial_location. These variables specifically were only
needed for DBX debugging info. Notice that their last (non-null) use
was removed on 7e0db0cdf (2022), when -gstabs and -gxcoff functionality
were removed.
I have successfully bootstrapped the compiler with the changes below.
