since we don't want to insist on a version number at the start of the changelog every time. * Makefile.maint: Sync from coreutils a bit better. (sc_trailing_blank): Renamed from sc_trailing_space. All uses changed. (sc_no_if_have_config_h, sc_require_config_h): (sc_prohibit_assert_without_use): New rules. (sc_obsolete_symbols): Don't catch Makefile.maint itself. (sc_dd_max_sym_length): Fix leading spaces in rule. (sc_system_h_headers): Prefix with @. (sc_useless_cpp_parens, m4-check): Output line numbers. (changelog-check): Allow version only in head. * data/c.m4: Use "defined FOO" instead of "defined (FOO)", to satisfy new Makefile.maint rule. * data/glr.c: Likewise. * data/glr.cc: Likewise. * data/lalr1.cc: Likewise. * data/yacc.c: Likewise. * lib/ebitsetv.c: Likewise. * lib/lbitset.c: Likewise. * lib/subpipe.c: Likewise. * lib/timevar.c: Likewise. * src/system.h: Likewise. * data/yacc.c (YYSTYPE): Don't generate trailing spaces in output. * djgpp/Makefile.maint: Add copyright notice. * djgpp/README.in: Likewise. * djgpp/config.bat: Likewise. * djgpp/config.site: Likewise. * djgpp/config_h.sed: Likewise. * djgpp/djunpack.bat: Likewise. * djgpp/config.sed: Fix copyright notice to match standard format. * djgpp/subpipe.h: Likewise. * lib/bitsetv-print.c: Likewise. * lib/bitsetv.c: Likewise. * lib/subpipe.h: Likewise. * lib/timevar.c: Likewise. * lib/timevar.h: Likewise. * djgpp/subpipe.c: Use standard recipe for config.h. * lib/abitset.c: Likewise. * lib/bitset.c: Likewise. * lib/bitset_stats.c: Likewise. * lib/bitsetv-print.c: Likewise. * lib/bitsetv.c: Likewise. * lib/ebitsetv.c: Likewise. * lib/get-errno.c: Likewise. * lib/lbitset.c: Likewise. * lib/subpipe.c: Likewise. * lib/timevar.c: Likewise. * lib/vbitset.c: Likewise. * tests/local.at: Likewise. * src/scan-gram.l: Don't include verify.h, since system.h does that for us. * .x-sc_require_config_h: New file. * .x-sc_unmarked_diagnostics: New file.

/* Timing variables are used to measure elapsed time in various
|
|
portions of the compiler. Each measures elapsed user, system, and
|
|
wall-clock time, as appropriate to and supported by the host
|
|
system.
|
|
|
|
Timing variables are defined using the DEFTIMEVAR macro in
|
|
timevar.def. Each has an enumeral identifier, used when referring
|
|
to the timing variable in code, and a character string name.
|
|
|
|
Timing variables can be used in two ways:
|
|
|
|
- On the timing stack, using timevar_push and timevar_pop.
|
|
Timing variables may be pushed onto the stack; elapsed time is
|
|
attributed to the topmost timing variable on the stack. When
|
|
another variable is pushed on, the previous topmost variable is
|
|
`paused' until the pushed variable is popped back off.
|
|
|
|
- As a standalone timer, using timevar_start and timevar_stop.
|
|
All time elapsed between the two calls is attributed to the
|
|
variable.
