DF usage in loop-invariant.c (PR46590) · 6541e97d

- df_live is already present at -O2, so we only need to add it and
  mark all blocks dirty for -O

- df_process_deferred_rescans should be enough to force a rescan of
  blocks affected by moving invariants, but calling it in find_defs
  means that we don't do any rescans for the final loop

2019-04-04  Richard Sandiford  <richard.sandiford@arm.com>

gcc/
	PR rtl-optimization/46590
	* loop-invariant.c (find_defs): Move df_remove_problem and
	df_process_deferred_rescans to move_invariants.
	Move df_live_add_problem and df_live_set_all_dirty calls
	to move_invariants.
	(move_invariants): Likewise.
	(move_loop_invariants): Likewise, making the df_live calls
	conditional on -O.  Remove the problem again if we added it
	locally.

PR c++/81866 - ICE with member template and default targ. · e53ec543

This testcase manages to find a way to look up the partial instantiation of
B for the default argument of C before we've created the partial
instantiation of B as part of the normal instantiation of the members of A.
Which we can deal with, but we were getting confused because the partial
instantiation was stored with a RECORD_TYPE specialization rather than
TEMPLATE_DECL.

[ARC]PR 88409: miscompilation due to missing cc clobber in longlong.h macros · 67a9a711

simple test such as below was failing.

| void main(int argc, char *argv[])

|    size_t total_time = 115424;                       // expected 115.424

|    printf("%s %d %lf\n", "secs", total_time, secs);  // prints 113.504
|    printf("%d\n", (size_t)secs);
| }

The printf eventually called into glibc stdlib/divrem.c:__mpn_divrem()
which uses the __arc__ specific inline asm macros from longlong.h which
were causing miscompilation.

S/390: arch13: Add support for new select instruction · 618eef38

Compared to the load on condition instructions we already have the new
