Hi,

this assertion in branch_prob:

  if (bb == ENTRY_BLOCK_PTR_FOR_FN (cfun)->next_bb)
    {
      location_t loc = DECL_SOURCE_LOCATION (current_function_decl);
      gcc_checking_assert (!RESERVED_LOCATION_P (loc));

had been correct until:

2021-08-11  Bernd Edlinger  <bernd.edlinger@hotmail.de>

	PR debug/101598
	* gcc-interface/trans.c (Subprogram_Body_to_gnu): Set the
	DECL_SOURCE_LOCATION of DECL_IGNORED_P gnu_subprog_decl to
	UNKNOWN_LOCATION.

was installed.

Tested on x86-64/Linux, OK for mainline and 12 branch?


2022-10-24  Eric Botcazou  <ebotcazou@adacore.com>

	* profile.cc (branch_prob): Be prepared for ignored functions with
	DECL_SOURCE_LOCATION set to UNKNOWN_LOCATION.
