2017-12-19[arm] PR target/82975: Guard against reg_renumber being NULL in arm.hKyrylo Tkachov4-2/+33
In this bug we ICE when checking REGNO_OK_FOR_INDEX_P on arm during pre-IRA scheduling. This is because REGNO_OK_FOR_INDEX_P ends up checking the reg_renumber array. Before IRA reg_renumber is NULL and thus we segfault. The fix is to guard the use of reg_renumber in the logic in TEST_REGNO in arm.h. On aarch64, for example, we also guard against the reg_renumber == NULL case. This fixes the ICE. I also remove the part of the comment that muses on when reg_renumber is available as with this patch it should now be safe to use at any point. Bootstrapped and tested on arm-none-linux-gnueabihf. PR target/82975 * config/arm/arm.h (TEST_REGNO): Check reg_renumber is set before accessing it. Adjust comment. * gcc.dg/pr82975.c: New test. From-SVN: r255830

2017-12-18testsuite: add coverage for diagnostics relating to inlining (PR ↵David Malcolm11-3/+425
tree-optimization/83336) In theory, the diagnostics subsystem can print context information on code inlining when diagnostics are emitted by the middle-end, describing the chain of inlined callsites that led to a particular warning, but PR tree-optimization/83336 describes various issues with this. An underlying issue is that we have very little automated testing for this code: gcc.dg/tm/pr52141.c has a test, but in general, prune.exp filters out the various "inlined from" lines. The following patch adds test coverage for it for C and C++ via a new testsuite plugin, which emits a warning from the middle-end; the test cases use dg-regexp to verify that the "inlined from" lines are emitted correctly, with the correct function names and source locations. Doing so requires a change to prune.exp: the dg-regexp lines have to be handled *before* the "inlined from" lines are stripped. gcc/testsuite/ChangeLog: PR tree-optimization/83336 * g++.dg/cpp0x/missing-initializer_list-include.C: Update for changes to prune.exp's handling of dg-regexp. * g++.dg/plugin/diagnostic-test-inlining-1.C: New test case. * g++.dg/plugin/plugin.exp (plugin_test_list): Add it, via gcc.dg's plugin/diagnostic_plugin_test_inlining.c. * gcc.dg/plugin/diagnostic-test-inlining-1.c: New test case. * gcc.dg/plugin/diagnostic-test-inlining-2.c: Likewise. * gcc.dg/plugin/diagnostic-test-inlining-3.c: Likewise. * gcc.dg/plugin/diagnostic-test-inlining-4.c: Likewise. * gcc.dg/plugin/diagnostic_plugin_test_inlining.c: New test plugin. * gcc.dg/plugin/plugin.exp (plugin_test_list): Add them. * lib/prune.exp (prune_gcc_output): Move call to handle-dg-regexps to before the various text stripping regsup invocations, in particular, to before the stripping of "inlined from".
