[PATCH 1/2] debug: Refactor and expand _FORTIFY_SOURCE tests
Siddhesh Poyarekar
siddhesh@sourceware.org
Wed Jan 5 01:39:45 GMT 2022
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 tests to include _FORTIFY_SOURCE=3.
