2016-08-31selftest: split out named_temp_file from temp_source_fileDavid Malcolm1-14/+35
Split out a new base class for temp_source_file, named_temp_file, moving the deletion to the base class dtor, so that we can write out temporary files in other ways in selftests. gcc/ChangeLog: * selftest.c (selftest::named_temp_file::named_temp_file): New ctor. (selftest::temp_source_file::~temp_source_file): Move to... (selftest::named_temp_file::~named_temp_file): ...here. (selftest::test_named_temp_file): New function.

2016-08-18Evict selftest tempfiles from the diagnostics file cacheDavid Malcolm1-0/+1
Selftests can use class selftest::temp_source_file to write out files for testing input-handling, and the files are unlinked in the dtor. This leads to stale entries in input.c's cache of file content, which could lead to errors if a temporary filename gets reused during a run of the selftests. We don't normally expect files to be "deleted from under us", so special-case this by adding a special way for temp_source_file's dtor to purge any cache entries referring to it. gcc/ChangeLog: * input.c (diagnostics_file_cache_forcibly_evict_file): New function. * input.h (diagnostics_file_cache_forcibly_evict_file): New declaration. * selftest.c (selftest::temp_source_file::~temp_source_file): Evict m_filename from the diagnostic file cache. From-SVN: r239570

gcc/ChangeLog: * selftest.c (selftest::assert_streq): Handle NULL values of val_actual and val_expected. From-SVN: r238479
2016-06-13selftests: improve reported failure locationsDavid Malcolm1-10/+10
This patch introduce a selftest::location struct to wrap up __FILE__ and __LINE__ information (and __FUNCTION__) throughout the selftests, allowing location information to be passed around. It updates the helper functions in pretty-print.c to pass through the precise location of each test, so that if a failure occurs, the correct line number is printed, rather than a line within a helper function. gcc/ChangeLog: * input.c (test_reading_source_line): Use SELFTEST_LOCATION. * pretty-print.c (assert_pp_format_va): Add location param and use it with ASSERT_STREQ_AT. (assert_pp_format): Add location param and pass it to assert_pp_format_va. (assert_pp_format_colored): Likewise. (ASSERT_PP_FORMAT_1): New. (ASSERT_PP_FORMAT_2): New. (ASSERT_PP_FORMAT_3): New. (test_pp_format): Provide SELFTEST_LOCATION throughout, either explicitly, or implicitly via the above macros. * selftest.c (selftest::pass): Use a selftest::location rather than file and line. (selftest::fail): Likewise. Print the function name. (selftest::fail_formatted): Likewise. (selftest::assert_streq): Use a selftest::location rather than file and line. * selftest.h (selftest::location): New struct. (SELFTEST_LOCATION): New macro. (selftest::pass): Accept a const location & rather than file and line. (selftest::fail): Likewise. (selftest::fail_formatted): Likewise. (selftest::assert_streq): Likewise. (ASSERT_TRUE): Update for above changes, using SELFTEST_LOCATION. (ASSERT_FALSE): Likewise. (ASSERT_EQ): Likewise. (ASSERT_NE): Likewise. (ASSERT_STREQ): Likewise. (ASSERT_PRED1): Likewise. (ASSERT_STREQ_AT): New macro. From-SVN: r237410
2016-06-13selftest: show values when ASSERT_STREQ failsDavid Malcolm1-0/+32
