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".

The Fortran committee has decided to rename the upcoming Fortran 2015 standard to Fortran 2018. This is not a reflection of a three year delay in the process, but rather they are following other standards in adopting the year of publication for the name. For more details see N2144. This patch renames GFC_STD_F2015 to GFC_STD_F2018, and makes it a separate flag rather than an alias for GFC_STD_GNU. Also, it adds a -std=f2018 argument, and documents it.
