2015-01-30Always pass explicit location to fatal_error.Joseph Myers1-13/+20
The patch <https://gcc.gnu.org/ml/gcc-patches/2014-11/msg00698.html> adding an overload for fatal_error that passes an explicit location broke gcc.pot regeneration because xgettext cannot handle function overloads with the diagnostic string argument in different positions. As the desired direction is for all diagnostics to have explicit locations, this patch addresses the regression by removing the version of fatal_error that does not pass a location, passing explicit input_location everywhere (in the hope that those will incrementally be changed to other locations, much as with the addition of a location argument to pedwarn some time ago - a lot of cases aren't meaningfully associated with a source file so UNKNOWN_LOCATION may be better). Note that this patch does not attempt to fix any existing issues with these diagnostics (such as wrongly starting with capital letters or ending with '.' or '\n'); it just adds the input_location argument. Bootstrapped with no regressions for x86_64-unknown-linux-gnu (Go excluded). gcc: * diagnostic.c (fatal_error (const char *, ...)): Remove function. * diagnostic-core.h (fatal_error (const char *, ...)): Remove prototype. * toplev.h (init_asm_output): Update comment on use of UNKNOWN_LOCATION with fatal_error. * cgraph.c, collect-utils.c, collect2.c, config/arc/arc.c, config/arc/arc.md, config/avr/avr.c, config/c6x/c6x.h, config/darwin.c, config/host-darwin.c, config/i386/host-cygwin.c, config/i386/intelmic-mkoffload.c, config/nios2/nios2.c, config/nvptx/mkoffload.c, config/nvptx/nvptx.h, config/rs6000/host-darwin.c, config/rs6000/rs6000.c, config/s390/s390.c, gcc.c, gcov-io.h, gcov-tool.c, ggc-common.c, ggc-page.c, graph.c, ipa-inline-analysis.c, ipa-reference.c, lto-cgraph.c, lto-section-in.c, lto-streamer-in.c, lto-streamer.c, lto-wrapper.c, objc/objc-act.c, opts.c, passes.c, plugin.c, tlink.c, toplev.c, tree-streamer-in.c, varpool.c: All callers of fatal_error changed to pass input_location as first argument. gcc/c-family: * c-opts.c, c-pch.c, cppspec.c: All callers of fatal_error changed to pass input_location as first argument. gcc/cp: * class.c, except.c, parser.c, pt.c: All callers of fatal_error changed to pass input_location as first argument. gcc/fortran: * f95-lang.c, gfortranspec.c, trans-const.c, trans-expr.c: All callers of fatal_error changed to pass input_location as first argument. gcc/java: * class.c, expr.c, jcf-parse.c, jvspec.c: All callers of fatal_error changed to pass input_location as first argument. gcc/lto: * lto-object.c, lto-symtab.c, lto.c: All callers of fatal_error changed to pass input_location as first argument. libcc1: * plugin.cc: All callers of fatal_error changed to pass input_location as first argument.
