I like the idea. Here's another iteration of the patch kit, which implements it (mostly). David Malcolm (15): Selftest framework (unittests v4) Add selftests to bitmap.c Add selftests to tree-cfg.c Add selftests to et-forest.c Add selftests to fold-const.c Add function-tests.c Fix warning in function-tests.c Add selftests to gimple.c Add hash-map-tests.c Add hash-set-tests.c Add selftests to input.c Add rtl-tests.c Add selftests to tree.c Add selftests to vec.c RFC: Add ggc-tests.c gcc/Makefile.in | 9 +- gcc/bitmap.c | 92 ++++++++ gcc/common.opt | 4 + gcc/et-forest.c | 99 ++++++++ gcc/fold-const.c | 66 ++++++ gcc/function-tests.c | 632 +++++++++++++++++++++++++++++++++++++++++++++++++++ gcc/ggc-tests.c | 302 ++++++++++++++++++++++++ gcc/gimple.c | 103 +++++++++ gcc/hash-map-tests.c | 81 +++++++ gcc/hash-set-tests.c | 57 +++++ gcc/input.c | 107 +++++++++ gcc/rtl-tests.c | 98 ++++++++ gcc/selftest.c | 152 +++++++++++++ gcc/selftest.h | 270 ++++++++++++++++++++++ gcc/toplev.c | 51 +++++ gcc/toplev.h | 2 + gcc/tree-cfg.c | 264 +++++++++++++++++++++ gcc/tree.c | 47 ++++ gcc/vec.c | 142 ++++++++++++ 19 files changed, 2575 insertions(+), 3 deletions(-) create mode 100644 gcc/function-tests.c create mode 100644 gcc/ggc-tests.c create mode 100644 gcc/hash-map-tests.c create mode 100644 gcc/hash-set-tests.c create mode 100644 gcc/rtl-tests.c create mode 100644 gcc/selftest.c create mode 100644 gcc/selftest.h -- 1.8.5.3
