I built successfully the GCC snapshot of about July 20, 2014 for language=c. Then, I ran the testsuite. It seems 106,573 GCC tests were passed. in gcc/testsuite/gcc/, there's the large file named gcc.sum : $ more gcc.sum | grep PASS|wc 106573 734696 8219369 // 106,573 lines with PASS How do I produce (or find) the model (ideal) test results, as posted by H.J. Lu and others to the testresults mailing list? Thanks, David Bernier
