Dan Gohman 4d6149f356 Update LoopSimplify and LoopUnswitch to use the new makeLoopInvariant 
function.

Dan Gohman 03d5d0f451 Fix indvars to not assume that a loop with a single unique exit 
block has a single unique exiting block.

Dan Gohman 6f6d864815 Introduce a new LoopInfo utility function makeLoopInvariant, which 
works similar to isLoopInvariant, except that it will do trivial
hoisting to try to make the value loop invariant if it isn't already.
This makes it easier for transformation passes to clear trivial
instructions out of the way (the regular LICM pass doesn't run
until relatively late). This is code factored out of LoopSimplify
and other places.

Evan Cheng 26bed68f5b Fix pr4544. When remating, make sure the destination register fits the instruction definition. It may be mismatched due to sub-register coalescing. 
No test case yet because the code doesn't trigger until 75408 is re-applied.

Dale Johannesen 85ae7480d9 Don't delete asm's just because their inputs are undefined; 
xor R, R is a common and valid idiom for zeroing a register, for example.

Chris Lattner 105efaf3df rename Memo/Count to AnonGlobalIDs/NextAnonGlobalID to be more 
descriptive.  Thange them to keep track of the ID of a global that is
assigned, not the first mangled name returned for it.  Without doing this,
we are required to always use the same suffix for a global that gets 
mangled.  This means that we can mangle the same global once with $stub
and another time with $non_lazy_ptr or whatever.

Chris Lattner 327387156a remove Mangler::getTypeID and related data, it was only used for mangling 
local symbols and we haven't had type planes since llvm 1.9.

 2009-07-13 23:50:53 +00:00
Chris Lattner 15c6d8779b remove mangler support for mangling local names. Mangler should only be 
used with globals.

llvm-svn: 75557

Chris Lattner 874727fb73 fix CBE & MSIL backends to not use the mangler for non-global symbols.

Chris Lattner cf485bd781 the mangler should put suffixes on unnamed global's mangled names as well 
if present.

Chris Lattner ec8efcb44e Two changes: 
1) unique globals with the existing "Count" local in Mangler, not with
atomic nonsense.  Using atomics will give us nondeterminstic output
from the compiler when using multiple threads, which is bad.

2) Do not mangle an unknown global name with a type suffix.  We don't
   need this anymore now that llvm ir doesn't have type planes.

Eli Friedman 7e1716dc9d Canonicalize boolean +/- a constant to a select. 
(I think it's reasonably clear that we want to have a canonical form for 
constructs like this; if anyone thinks that a select is not the best 
canonical form, please tell me.)

Daniel Dunbar 4f57d77e40 NewNightlyTest.pl - Add -noremoveatend option. 
- Like -noremove, except the build directory is still purged prior to building
   but isn't removed at the end of the test run (so the build products can be
   examined if need be).

Dan Gohman 80a9942593 Move isLCSSAForm, isLoopInvariant, getCanonicalInductionVariable, 
and related functions out of LoopBase and into Loop, since they
are specific to BasicBlock-based loops. This also allows the code
to be moved out-of-line.
