Hi, to fix build error we change inline to always_inline. OK to commit? * malloc/malloc.c (alloc_perturb, free_perturb): use __always inline.

It pretty often refuses to inline functions that after inlining he could say delete half code as dead. Reason why it should be inlined is simple, unlikely branch is much cheaper than function call. I have a benchmark where noninlined version is 90 times slower than inlined one (which is mainly because there is big penalty for two calls in quick succession.) A following benchmark shows that inlining is better even if code is not in cache, it runs in 5 seconds with always inline but gcc default is 6 seconds. It uses standard trick of repeating code pattern many times so it will not be in cache. Also I modified alloc_perturb bit to bump size which causes inlining and memory access so inline version does not get optimized away. Trying to look at code size is bogus measure of cold code performance. Here inlined version is 226199 bytes and gcc default just 149422 bytes. That size also does not mean anything as in inline case only first 118299 bytes are read. That does not make much difference, when you change memset (foo, bar, n % 51515) to memset (foo, bar, n % 115) gcc decides expand memset which bumps code size to 362211 bytes, all read but it does not affect performance. > > * malloc/malloc.c (alloc_perturb, free_perturb): > > use __always inline. > > Capitalize a sentence.

This only tells me that the compiler should become more sophisticated over time, not that we should forver assume it can't do a good job. If we continue to hand inline things, there is zero incentive to make the compiler smarter about it.

And is worse performance in next ten years until that issues are fixed acceptable? To get smarter compiler you need to fill bugs where inliner misbehaves, just promising that we will not inline and asking to improve gcc will not help much. For start you should make gathering profile information in libc possible. Without that no compiler can make good decision as there are workloads where he should inline and in other workload he shouldn't.

And working around the compilers deficiencies nearly guarantees nothing will be done about it.

You have no guarantee that its just moderate amount. From your warnings it looks that compiler decided never inline anything. So how much does malloc_benchtest differ after you build with ./configure --disable-werror? On x86 simulating that with noinline gives 10% performance degradation which as half of total time spend in libc is in malloc+variants.
