Lessons learned from compiler error/warnings tests


For compile-time fortify checks (such as the wrappers for type-safe open/openat), we need to add tests in glibc which examine the compiler output for warnings and errors.

I do not want to add Dejagnu as a dependency to the glibc test suite, but I wonder if you could share any lessons learned from the testing support facility in GCC.

Would you suggest to mirror the GCC directives exactly?

I probably have to implement the testing directive parser as a small C program.

Thanks,
Florian
