Dan Gohman 0479aa5c0b Change class' public PassInfo variables to by initialized with the 
address of the PassInfo directly instead of calling getPassInfo.
This eliminates a bunch of dynamic initializations of static data.

Also, fold RegisterPassBase into PassInfo, make a bunch of its
data members const, and rearrange some code to initialize data
members in constructors instead of using setter member functions.

Evan Cheng 3f40c69083 On x86, it's safe to treat i32 load anyext as a normal i32 load. Ditto for i8 anyext load to i16.

Dan Gohman d78c400b5b Clean up the use of static and anonymous namespaces. This turned up 
several things that were neither in an anonymous namespace nor static
but not intended to be global.

Dale Johannesen e6942c31ea New test for tail merging 
llvm-svn: 51007
 2008-05-12 22:59:44 +00:00
Dale Johannesen 9d29283fc7 Be more aggressive about tail-merging small blocks 
if those blocks consist entirely of common instructions;
merging will not add an extra branch in this case.

Steve Naroff a98fe19c7e Fix <rdar://problem/5924576> clang -fsyntax-only generates "redefinition" errors when parsing AppKit that gcc does not.

Dale Johannesen c4c4d8e1f7 Further rework of tail merge algorithm. Not quite 
semantically identical, but little difference in
either results or execution speed; but it's much
easier to read, at least IMO.

 2008-05-12 19:47:18 +00:00
Nate Begeman cfcb56091b Add support for vicmp/vfcmp codegen, more legalize support coming. 
This is necessary to unbreak the build.

 2008-05-12 19:40:03 +00:00
Bill Wendling 70613b84da One real change - don't hoist something that's trivially rematerializable. It's 
possible for it to produce worse code than before.

The rest of this patch is code cleanup.

 2008-05-12 17:40:13 +00:00
Ted Kremenek 92f78f4c04 When reading in the DeclCtx during deserialization, register the DeclCtx of the 
ScopedDecl with the backpatcher, and *not* a local variable on the stack. The
value of DeclCtx gets filled in *later* by the backpatcher.
