Function Documentation

bt_callback()

int bt_callback ( void * data, uintptr_t pc, const char * filename, int lineno, const char * function )

static

A callback function passed to the backtrace_full function.   

References bt_stop, free(), and i.

Referenced by fancy_abort().

bt_err_callback()

void bt_err_callback ( void * data, const char * msg, int errnum )

static

A callback function passed to the backtrace_full function.  This is
called if backtrace_full has an error.   

References msg.

Referenced by diagnostics::context::action_after_output(), and fancy_abort().

build_message_string()

char * build_message_string	(	const char *	msg,
			... )

Return a malloc'd string containing MSG formatted a la printf.  The
caller is responsible for freeing the memory.   

References ap, and msg.

Referenced by diagnostics::text_sink::build_prefix(), diagnostics::text_sink::file_name_as_prefix(), and diagnostics::column_policy::get_location_text().

diagnostic_set_info()

void diagnostic_set_info	(	diagnostics::diagnostic_info *	diagnostic,
		const char *	gmsgid,
		va_list *	args,
		rich_location *	richloc,
		enum diagnostics::kind	kind )

Initialize DIAGNOSTIC, where the message GMSGID has not yet been
translated.   

References _, diagnostic_set_info_translated(), and gcc_assert.

diagnostic_set_info_translated()

void diagnostic_set_info_translated	(	diagnostics::diagnostic_info *	diagnostic,
		const char *	msg,
		va_list *	args,
		rich_location *	richloc,
		enum diagnostics::kind	kind )

Initialize DIAGNOSTIC, where the message MSG has already been
translated.   

References errno, gcc_assert, diagnostic::m_metadata, and msg.

Referenced by diagnostic_set_info().

fancy_abort()

void fancy_abort	(	const char *	file,
		int	line,
		const char *	function )

Report an internal compiler error in a friendly manner.  This is
the function that gets called upon use of abort() in the source
code generally, thanks to a special macro.   

References bt_callback(), bt_err_callback(), count, fnotice(), fputc(), diagnostics::get_text_for_kind(), global_dc, internal_error(), real_abort(), and trim_filename().

get_terminal_width()

int get_terminal_width

(

void

)

Return the value of the getenv("COLUMNS") as an integer. If the
value is not set to a positive integer, use ioctl to get the
terminal width. If it fails, return INT_MAX.   

References INT_MAX.

Referenced by print_specific_help(), and diagnostics::context::set_caret_max_width().

real_abort()

void real_abort ( void )

static

Disable warnings about quoting issues in the pp_xxx calls below
that (intentionally) don't follow GCC diagnostic conventions.   

Really call the system 'abort'.  This has to go right at the end of
this file, so that there are no functions after it that call abort
and get the system abort instead of our macro.   

References abort.

Referenced by diagnostics::context::action_after_output(), diagnostics::context::error_recursion(), and fancy_abort().

trim_filename()

const char * trim_filename

(

const char *

name

)

Given a partial pathname as input, return another pathname that
shares no directory elements with the pathname of __FILE__.  This
is used by fancy_abort() to print `internal compiler error in expr.cc'
instead of `internal compiler error in ../../GCC/gcc/expr.cc'.   

References this_file.

Referenced by emit_insn_modes_h(), fancy_abort(), fancy_abort(), new_adjust(), and new_mode().

Variable Documentation

bt_stop

const char* const bt_stop[]

static

Initial value:

=
{
  "main",
  "toplev::main",
  "execute_one_pass",
  "compile_file",
}

Functions at which to stop the backtrace print.  It's not
particularly helpful to print the callers of these functions.   

Referenced by bt_callback().

progname

const char* progname

Name of program invoked, sans directories.   

Referenced by diagnostic_finish_va(), diagnostic_finish_via_msg_buf(), display_help(), error(), execute(), fatal(), general_init(), diagnostics::column_policy::get_location_text(), internal_error(), main(), main(), main(), main(), main(), driver::maybe_print_and_exit(), print_usage(), print_version(), print_version(), read_state(), read_state_structures(), read_state_typedefs(), read_state_variables(), driver::set_progname(), usage(), warning(), write_insn_preds_c(), state_writer::write_state, state_writer::write_state_structures(), state_writer::write_state_typedefs(), state_writer::write_state_variables(), write_tm_constrs_h(), write_tm_preds_h(), and diagnostics::text_sink::~text_sink().
