Subject: [Bug tree-optimization/15579] [3.5 Regression] always_inline ignored at -O0
Date: Sat, 22 May 2004 22:36:00 -0000	[thread overview]
Message-ID: <20040521234444.11952.qmail@sourceware.org> (raw)

Confirmed, the problem is the attribute always_inline is ignored at -O0 causing these regressions.
Another problem is that the constants are not prograted even with -finline.
Here is a small example:
int ghgf(int);

static inline int __attribute__((always_inline)) a(int l)
{
  return ghgf(l);
}
int b()
{
  return a(1);
}
