10 years agoRefactor isInTailCallPosition handling
Tim Northover [Tue, 6 Aug 2013 09:12:35 +0000 (09:12 +0000)]
Refactor isInTailCallPosition handling

This change came about primarily because of two issues in the existing code.
Niether of:

define i64 @test1(i64 %val) {
  %in = trunc i64 %val to i32
  tail call i32 @ret32(i32 returned %in)
  ret i64 %val
}

define i64 @test2(i64 %val) {
  tail call i32 @ret32(i32 returned undef)
  ret i32 42
}

should be tail calls, and the function sameNoopInput is responsible. The main
problem is that it is completely symmetric in the "tail call" and "ret" value,
but in reality different things are allowed on each side.

For these cases:
1. Any truncation should lead to a larger value being generated by "tail call"
   than needed by "ret".
2. Undef should only be allowed as a source for ret, not as a result of the
   call.

Along the way I noticed that a mismatch between what this function treats as a
valid truncation and what the backends see can lead to invalid calls as well
(see x86-32 test case).

This patch refactors the code so that instead of being based primarily on
values which it recurses into when necessary, it starts by inspecting the type
and considers each fundamental slot that the backend will see in turn. For
example, given a pathological function that returned {{}, {{}, i32, {}}, i32}
we would consider each "real" i32 in turn, and ask if it passes through
unchanged. This is much closer to what the backend sees as a result of
ComputeValueVTs.

Aside from the bug fixes, this eliminates the recursion that's going on and, I
believe, makes the bulk of the code significantly easier to understand. The
trade-off is the nasty iterators needed to find the real types inside a
returned value.

default 'zero' address space (which is the address space assumed by
TargetLowering::getPointerTy()), having an index that
is a different size than the pointer can lead to inefficient
pointer calculations, (e.g. 64-bit adds for a 32-bit address space).

10 years agoIntroduce an optimisation for special case lists with large numbers of literal entries.
Peter Collingbourne [Mon, 5 Aug 2013 17:48:04 +0000 (17:48 +0000)]
Introduce an optimisation for special case lists with large numbers of literal entries.

Our internal regex implementation does not cope with large numbers
of anchors very efficiently.  Given a ~3600-entry special case list,
regex compilation can take on the order of seconds.  This patch solves
the problem for the special case of patterns matching literal global
names (i.e. patterns with no regex metacharacters).  Rather than
forming regexes from literal global name patterns, add them to
a StringSet which is checked before matching against the regex.
This reduces regex compilation time by an order of roughly thousands
when reading the aforementioned special case list, according to a
completely unscientific study.

No test cases.  I figure that any new tests for this code should
check that regex metacharacters are properly recognised.  However,
I could not find any documentation which documents the fact that the
syntax of global names in special case lists is based on regexes.
The extent to which regex syntax is supported in special case lists
should probably be decided on/documented before writing tests.

Fix invalid function pointers in bugpoint ExtractLoops

The ExtractLoops function tries to reduce the failing test case by extracting
one or more loops from the misoptimized piece of the program. In doing this,
ExtractLoops must keep the MiscompiledFunctions vector up-to-date by ensuring
that the pointers refer to functions in the current failing program.
Unfortunately, this is not trivial because:

 - ExtractLoops is iterative, and there are several early exits (and the
   MiscompiledFunctions vector must be consistent with the current program at
every non-fatal exit point).
 - Several of the utility functions used by ExtractLoops (such as
   TestOptimizer, some of which are called through the TestFn callback
parameter, and Linker::LinkModules) delete their inputs upon success.

This change adds several updates of the MiscompiledFunctions vector at
different points. The first is after the initial call to TestMergedProgram
which checks that the loop-extracted program still works. The second is after

This patch fixes the multiple breakages on ARM test-suite after the SLP
vectorizer was introduced by default on O3. The problem was an illegal
vector type on ARMTTI::getCmpSelInstrCost() <3 x i1> which is not simple.

Fix some issues with Mips16 floating when certain intrinsics are present.
This is actually an LLVM bug in the way it generates signatures for these
when soft float is enabled. For example, floor ends up having the signature
of int64(int64). The signature part is not the same as where the actual
parameter types are recorded, and those ARE of course int64(int64) when
soft float is enabled. (Yes, Mips16 hard float uses soft float but with
different runtime rounes but then has to interoperate with Mips32 using
normal floating point). This logic will eventually be moved to the
Mips16HardFloat pass so it's not worth sorting out these issues in LLVM
since nobody but Mips16 cares about these signatures, as far as I know,
and even I won't eventually either.
