c-common.c (get_source_date_epoch): Rename to cb_get_source_date_epoch.
gcc/c-family/ChangeLog:
2016-05-13 Eduard Sanou <dhole@openmailbox.org>
* c-common.c (get_source_date_epoch): Rename to
cb_get_source_date_epoch.
* c-common.c (cb_get_source_date_epoch): Use a single generic erorr
message when the parsing fails. Use error_at instead of fatal_error.
* c-common.h (get_source_date_epoch): Rename to
cb_get_source_date_epoch.
* c-common.h (cb_get_source_date_epoch): Prototype.
* c-common.h (MAX_SOURCE_DATE_EPOCH): Define.
* c-common.h (c_omp_region_type): Remove trailing comma.
* c-lex.c (init_c_lex): Set cb->get_source_date_epoch callback.
* c-lex.c (c_lex_with_flags): Remove initialization of
pfile->source_date_epoch.
gcc/ChangeLog:
2016-05-13 Eduard Sanou <dhole@openmailbox.org>
* doc/cppenv.texi: Note that the `%s` in `date` is a non-standard
extension.
* gcc.c (driver_handle_option): Call set_source_date_epoch_envvar.
* gcc.c (set_source_date_epoch_envvar): New function, sets
the SOURCE_DATE_EPOCH environment variable to the current time.
gcc/testsuite/ChangeLog:
2016-05-13 Eduard Sanou <dhole@openmailbox.org>
* gcc.dg/cpp/source_date_epoch-1.c: New file, test the proper
behaviour of the macros __DATE__ and __TIME__ when SOURCE_DATE_EPOCH
env var is set.
* gcc.dg/cpp/source_date_epoch-2.c: New file, test the error output
when parsing the SOURCE_DATE_EPOCH env var, and make sure it is only
shown once.
* lib/gcc-dg.exp (dg-set-compiler-env-var): New function, set env vars
during compilation.
* lib/gcc-dg.exp (restore-compiler-env-var): New function, restore env
vars set by dg-set-compiler-env-var.
libcpp/ChangeLog:
2016-05-13 Eduard Sanou <dhole@openmailbox.org>
* include/cpplib.h (cpp_callbacks): Add get_source_date_epoch
callback.
* include/cpplib.h (cpp_init_source_date_epoch): Remove prototype.
* init.c (cpp_init_source_date_epoch): Remove function.
* init.c (cpp_create_reader): Initialize pfile->source_date_epoch.
* internal.h (cpp_reader): Extend comment about source_date_epoch.
* macro.c (_cpp_builtin_macro_text): Use get_source_date_epoch
callback only once, read pfile->source_date_epoch on future passes.
Check that get_source_date_epoch callback is not NULL.
