From f87e22c52128d9d9c9a72a81ae3922b46ce52e59 Mon Sep 17 00:00:00 2001 From: David Malcolm Date: Thu, 18 Aug 2016 16:22:10 +0000 Subject: selftest.h: add class line_table_test input.c has a fixture class for running each selftest with a fresh line_table, and logic for looping over various interesting line_table test cases. This patch exposes the above in selftest.h so that such location-handling tests can be written in other files, renaming the class from temp_line_table to line_table_test. Also, the patch moves the stored line table ptr from being a member of the test class to being a global GC-root, to avoid it being collected if the GC runs during such a test. gcc/ChangeLog: * input.c (saved_line_table): New global. (class selftest::temp_line_table): Rename to line_table_test and move declaration to selftest.h, and drop field m_old_line_table. (selftest::temp_line_table::temp_line_table): Rename ctor to... (selftest::line_table_test::line_table_test): ...this. Add a default ctor. Store current value of line_table within saved_line_table. (selftest::temp_line_table::~temp_line_table): Rename dtor to... (selftest::line_table_test::~line_table_test): ...this, and restore line_table from the saved_line_table, rather than m_old_line_table. (selftest::test_accessing_ordinary_linemaps): Update for above renaming. (selftest::test_lexer): Likewise. (struct selftest::lexer_test): Likewise. (selftest::lexer_test::lexer_test): Likewise. (selftest::input_c_tests): Move the looping over test cases from here into... (selftest::for_each_line_table_case): New function. * input.h (saved_line_table): New decl. * selftest.h (struct selftest::line_table_case): New forward decl. (class selftest::line_table_test): New class, moved here from selftest::temp_line_table in input.c, and renamed. (selftest::for_each_line_table_case): New decl.
