[Bug tree-optimization/35618] [4.3 regression] ICE in cgraph_estimate_size_after_inlining, at ipa-inline.c:188

["rguenth at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #8 from rguenth at gcc dot gnu dot org  2008-05-23 14:35 -------
Confirmed.

Testcase, -Os -fno-unit-at-a-time

static void __resched_task(void *p, int tif_bit);
static inline __attribute__((always_inline))
void resched_task(void *p) {  __resched_task(p, 2);  }
static void __resched_task(void *p, int tif_bit) { }
void check_preempt_curr_idle(void *p)
{
  resched_task(p);
}

if you put an inline onto the definition of __resched_task the testcase
also ICEs for -O and -O2, so quite likely we are more agressive with -Os
inlining but decide so after-the-fact which confuses the size estimates.

Honza, can you please have a look here?
