A couple of things: (a) Could you please add a test-case for the above symbols ? See testsuite/gcc.dg/missing-header-fixit-4.c for a similar example for printf. (b) The patch is missing changelog. I assume you've tested the patch with bootstrap+regtest ? Thanks, Prathamesh > -- > 2.37.2 ^ permalink raw reply [flat|nested] 4+ messages in thread

Hi Prathmesh Many thanks for your reply. I built gcc by typing "make", I understand that is the bootstrap. I don't know about regtest, could you direct me to a guide please. I didn't add a test; I can do that now. Is there an FAQ you can direct me to to run those tests please. Running ‘make check-c’ now, its taking along time on gcc.c-torture. Is there a way I can quickly run only the gcc.dg missing header tests? BTW, do you know if a change could be made to detect dejagnu being installed? Would be good if "make check" quickly failed if the "runtest" command from dejagnu was not found. I needed to install these two packages. Would be good to get a hint when running ‘make check-c’ autogen dejagnu For the files like missing-header-fixit-4.c is it sufficient to just add a file to that folder?

I don't know about regtest, could you direct me to a guide please. Hi, Sorry for slow response. It depends on how you configured gcc. If bootstrap is enabled (which is by default), then make would bootstrap gcc. Typically for development, we disable bootstrap by passing --disable-bootstrap to configure for faster builds, and then validate the patch with final bootstrap+test. For regression testing, you'd have to (1) Bootstrap the trunk without the patch, (2) Bootstrap the trunk with patch, (3) Compare the two build dirs with $gcc-src/contrib/compare_tests. and address issues for the FAIL'd tests. > > I didn't add a test; I can do that now.

Yes, adding the file in $gcc-src/gcc/testsuite/gcc.dg/ should be sufficient. For eg, to only run missing-header-fixit-4.c this should work: make check-gcc RUNTESTFLAGS="dg.exp=missing-header-fixit-4.c" Thanks, Prathamesh > Cheers > Jonny ^ permalink raw reply [flat|nested] 4+ messages in thread
