Jim Grosbach 5cba8de2c8 vml[as].f32 cause stalls in following advanced SIMD instructions. Avoid using 
them for scalar floating point operations for now.

Dan Gohman 34341e69c4 Make -print-machineinstrs more readable. 
- Be consistent when referring to MachineBasicBlocks: BB#0.
 - Be consistent when referring to virtual registers: %reg1024.
 - Be consistent when referring to unknown physical registers: %physreg10.
 - Be consistent when referring to known physical registers: %RAX
 - Be consistent when referring to register 0: %reg0
 - Be consistent when printing alignments: align=16
 - Print jump table contents.
 - Don't print host addresses, in general.
 - and various other cleanups.

Dan Gohman 18dc1c5c9e Factor out more code into addCommonCodeGenPasses. The JIT wasn't 
previously running CodePlacementOpt. Also print headers before
each dump in -print-machineinstrs mode, so that it's clear which
dump is which.

Mike Stump 0a65b636ce Fix -pthread on dragonfly. Patch by Sascha Wildner. 
llvm-svn: 85679
 2009-10-31 20:11:46 +00:00
Chris Lattner b2c0e243c5 Make blockaddress(@func, null) be valid, and make 'deleting a basic 
block with a blockaddress still referring to it' replace the invalid 
blockaddress with a new blockaddress(@func, null) instead of a 
inttoptr(1).

This changes the bitcode encoding format, and still needs codegen 
support (this should produce a non-zero value, referring to the entry
block of the function would also be quite reasonable).

 2009-10-31 19:54:06 +00:00
Jim Grosbach 5d994048dd Expand 64 bit left shift inline rather than using the libcall. For now, this 
is unconditional. Making it still use the libcall when optimizing for size
would be a good adjustment.

Benjamin Kramer 7e06083a3a Add missing colons for FileCheck.

Jim Grosbach 7a949d8b05 The universal SDKROOT should only be assigned when hosted. Otherwise the 
SDKROOT can refer to the target when we're building for the host.

Chris Lattner a742b8f94f add a comment.

 2009-10-31 17:48:31 +00:00
Dan Gohman 2d02ff8cbb Revert r85667. LoopUnroll currently can't call utility functions which 
auto-update the DominatorTree because it doesn't keep the DominatorTree
current while it works.

Douglas Gregor 954de17977 Implement "incremental" template instantiation for non-type template 
parameters and template type parameters, which occurs when
substituting into the declarations of member templates inside class
templates. This eliminates errors about our inability to "reduce
non-type template parameter depth", fixing PR5311.

Also fixes a bug when instantiating a template type parameter
declaration in a member template, where we weren't properly reducing
the template parameter's depth.

LLVM's StringSwitch header now parses.

Dan Gohman 144694bcb7 Remove redundant code. 
llvm-svn: 85668
 2009-10-31 16:16:41 +00:00
Dan Gohman 041e2dbad1 Merge the enhancements from LoopUnroll's FoldBlockIntoPredecessor into 
MergeBlockIntoPredecessor. This makes SimplifyCFG slightly more aggressive,
and makes it unnecessary for LoopUnroll to have its own copy of this code.

Rajaratnam!

 2009-10-31 15:48:08 +00:00
Dan Gohman 880c92ac1c Rename forgetLoopBackedgeTakenCount to forgetLoop, because it 
clears out more information than just the stored backedge taken count.

llvm-svn: 85664
 2009-10-31 15:04:55 +00:00

Dan Gohman f70e76c435 Rename UnrollLoop.cpp to LoopUnroll.cpp, and LoopUnroll.cpp to 
LoopUnrollPass.cpp, for consistency with other passes which are
similarly split.

llvm-svn: 85659
 2009-10-31 14:37:31 +00:00
Dan Gohman fb7f0e57b6 Remove CodeGenLICM. It's largely obsoleted by MachineLICM's new ability 
to unfold loop-invariant loads.

Dan Gohman ac45c9171d Make ScalarEvolutionAliasAnalysis slightly more aggressive, by making an 
underlying alias call even for non-identified-object values.

 2009-10-31 14:22:52 +00:00
Dan Gohman ba8735d25a When discarding SrcValue information, discard all of it so that code 
that uses this information knows to behave conservatively.
