Commit Message

Siddhesh Poyarekar Jan. 5, 2022, 4:45 a.m. UTC 
  Rename all debug/tst-chk* tests to reflect the fortification level
they're testing and any additional macros so that rules for them can be
autogenerated.  tst-chk0* are without fortification, tst-chk1 for
_FORTIFY_SOURCE=1 and so on.  This allows easier replication of the
tests to check additional macros.

The change also expands the -lfs to include _FORTIFY_SOURCE=3.

Nice, it does simplify the required rules.  Maybe you could also extend it to
LFS as well:

And then remove the '#define _FILE_OFFSET_BITS 64' so the rule is applied
regardless whether the file defines or not.

Since you are touching, put one file per line.

While it works for _FILE_OFFSET_BITS, I doubt if it'll work for 
_GNU_SOURCE since it will get overridden by libc-symbols.h.

At some point I want to do a cleanup where libc-symbols.h undefines 
_GNU_SOURCE for tests and only tests that require it, define it 
explicitly.  Then we can properly auto-generate _FORTIFY_SOURCE tests 
out of tst-chk-0.c just like we do for mcheck and malloc-check tests.

May I keep it like this for now and do this additional cleanup later?
