Andrew Trick [Mon, 6 May 2013 17:58:18 +0000 (17:58 +0000)]
Rotate multi-exit loops even if the latch was simplified.

Test case by Michele Scandale!

Fixes PR10293: Load not hoisted out of loop with multiple exits.

There are few regressions with this patch, now tracked by
rdar:13817079, and a roughly equal number of improvements. The
regressions are almost certainly back luck because LoopRotate has very
little idea of whether rotation is profitable. Doing better requires a
more comprehensive solution.

This checkin is a quick fix that lacks generality (PR10293 has
a counter-example). But it trivially fixes the case in PR10293 without
interfering with other cases, and it does satify the criteria that
LoopRotate is a loop canonicalization pass that should avoid
heuristics and special cases.

I can think of two approaches that would probably be better in
the long run. Ultimately they may both make sense.

(1) LoopRotate should check that the current header would make a good
loop guard, and that the loop does not already has a sufficient
guard. The artifical SimplifiedLoopLatch check would be unnecessary,
and the design would be more general and canonical. Two difficulties:

- We need a strong guarantee that we won't endlessly rotate, so the
  analysis would need to be precise in order to avoid the
  SimplifiedLoopLatch precondition.

- Analysis like this are usually based on SCEV, which we don't want to
  rely on.

(2) Rotate on-demand in late loop passes. This could even be done by
shoving the loop back on the queue after the optimization that needs
it. This could work well when we find LICM opportunities in
multi-branch loops. This requires some work, and it doesn't really
solve the problem of SCEV wanting a loop guard before the analysis.

Simplify JIT unit test #ifdefs

Several platforms need to disable all old-JIT unit tests, since they only
support the new MCJIT.  This currently done via #ifdef'ing out those tests
in the ExecutionEngine/JIT/*.cpp files.  As those #ifdef's have grown
historically, we now have a number of repeated directives which -in total-
cover nearly the whole file, but leave a couple of helper functions out.
When building the tests with clang itself, those helper functions now
cause spurious "unused function" warnings.

To fix those warnings, and also to remove the duplicate #ifdef conditions
and make it easier to disable the tests for a new target, this patch
consolidates the #ifdefs into a single one per file, which covers all
the tests including all helper routines.

Arnold Schwaighofer [Sun, 5 May 2013 01:54:46 +0000 (01:54 +0000)]
PatternMatch: Matcher for (un)ordered floating point min/max

Add support for matching 'ordered' and 'unordered' floating point min/max

In LLVM we can express min/max functions as a combination of compare and select.
We have support for matching such constructs for integers but not for floating
point. In floating point math there is no total order because of the presence of
'NaN'. Therefore, we have to be careful to preserve the original fcmp semantics
when interpreting floating point compare select combinations as a minimum or
maximum function. The resulting 'ordered/unordered' floating point maximum
function has to select the same value as the select/fcmp combination it is based

 ordered_max(x,y)   = max(x,y) iff x and y are not NaN, y otherwise
 unordered_max(x,y) = max(x,y) iff x and y are not NaN, x otherwise
 ordered_min(x,y)   = min(x,y) iff x and y are not NaN, y otherwise
 unordered_min(x,y) = min(x,y) iff x and y are not NaN, x otherwise

This matches the behavior of the underlying select(fcmp(olt/ult/.., L, R), L, R)

Any code using this predicate has to preserve this semantics.

A follow-up patch will use this to implement floating point min/max reductions
in the vectorizer.

As with global accesses, external functions could exist anywhere in

patch implements the fragment as (roughly):
    movz x16, #:abs_g3:somefunc
    movk x16, #:abs_g2_nc:somefunc
    movk x16, #:abs_g1_nc:somefunc

but it is unclear that would be more efficient and can only be tested

pass on AArch64.
