Evan Cheng 4465954638 Enable Chris' value propagation change. It make available known sign, zero, one bits information for values that are live out of basic blocks. The goal is to eliminate unnecessary sext, zext, truncate of values that are live-in to blocks. This does not handle PHI nodes yet.

Evan Cheng ef0b7cc2d5 On x86, if the only use of a i64 load is a i64 store, generate a pair of double load and store instead.

Bill Wendling 207495d8ea Revert r66765 and r66766. These were causing build failures on Darwin.

Nick Lewycky c46949c278 Regenerate.

 2009-03-12 03:34:33 +00:00
Nick Lewycky ca433d8a84 Set ARCH to x86 on mixed 32/64-bit Linux systems. 
Remove the explicit if OS = Darwin test around the setting of -m32/-m64.

Sanjiv Gupta 8bb50e2344 Forgot to check-in this as part of 7761.

Sanjiv Gupta f883419b2f Banksel optimization is now based on the section names of symbols, since the symbols in one section will always be put into one bank.

Dale Johannesen 9cdb9bb3e5 Allow for switch values bigger than 64 bits. 
llvm-svn: 66751
 2009-03-12 01:20:06 +00:00
Daniel Dunbar aa75c9d8d8 Add StringMap::lookup. 
llvm-svn: 66750
 2009-03-12 01:16:06 +00:00
Dale Johannesen 5a41b2def5 Fix some nondeterministic behavior when forwarding 
from a switch table.  Multiple table entries that
branch to the same place were being sorted by the
pointer value of the ConstantInt*; changed to sort
by the actual value of the ConstantInt.

Evan Cheng 690b635aa6 Also pass -gcc-tool-args when building a shared object.

 2009-03-12 00:53:34 +00:00
Dan Gohman 5637df37cd Revert r66024. The JIT encoding for CALLpcrel32 is wrong -- see PR3773, and the 
assembly text output uses an indirect call ("call *") instead of a direct call.

Owen Anderson aabe06d92a Reorganization: Move the Spiller out of VirtRegMap.cpp into its own files. No (intended) functionality change. 
llvm-svn: 66720
 2009-03-11 22:31:21 +00:00
Bill Wendling 42adc73a2b Add a -no-implicit-float flag. This acts like -soft-float, but may generate 
floating point instructions that are explicitly specified by the user.

 2009-03-11 22:30:01 +00:00
Dale Johannesen 08ccba73a7 Skip interleaved debug info when fast-forwarding through 
allocations.  Apparently the assumption is there is an
instruction (terminator?) following the allocation so I
am allowing the same assumption.

 2009-03-11 22:19:43 +00:00
Evan Cheng 6cba561648 My last coalescer fix introduced a subtler one. It's aborting a commuting optimization too late and left the live intervals to be out of sync with instructions. This fixes 8b10b. 
llvm-svn: 66715
 2009-03-11 22:18:44 +00:00
Dale Johannesen f61c8e81bd Debug intriniscs should be skipped when looking 
for a dependency, not terminate the search.

Anton Korobeynikov 7d4d379a00 Another bug :( 
llvm-svn: 66708
 2009-03-11 21:05:21 +00:00
Torok Edwin 5202cc0036 Make Print callable from a pass's print method: add const qualifier. No 
functionality change.

llvm-svn: 66700
 2009-03-11 20:50:17 +00:00
Anton Korobeynikov 38961d5bd6 I should definitely read make docs someday :( 
llvm-svn: 66699
 2009-03-11 20:40:15 +00:00
Gabor Greif 42225e50f3 do not pretend llvm/.../*.h being system headers 
llvm-svn: 66697
 2009-03-11 20:23:40 +00:00
Anton Korobeynikov 3b046d084e Unbreak the build. Dunno, why it did not fail on mingw :( 
llvm-svn: 66692
 2009-03-11 20:16:05 +00:00
Duncan Sands 4581bebf2a It makes no sense to have a ODR version of common 
linkage, so remove it.

llvm-svn: 66690
 2009-03-11 20:14:15 +00:00
Gabor Greif 605c7cab75 fix validator errors

Anton Korobeynikov a09ba46ee3 Disable plugins / shared stuff generation on windows targets. 
This fixes fallout from recent PIC/delibtoolize changes and unbreaks
build on cygming.

llvm-svn: 66686
 2009-03-11 19:49:42 +00:00
Mon P Wang 25c6a46a81 For yonah, fix a vector shuffle case for v16i8 where we didn't properly clear some bits. 
llvm-svn: 66684
 2009-03-11 18:47:57 +00:00
Chris Lattner be0d672ac4 implement support for C-style string literal concatenation in td files. 
llvm-svn: 66663
 2009-03-11 17:08:13 +00:00
Chris Lattner 93e87652f2 fix PR3785, a valgrind error on test/CodeGen/ARM/pr3502.ll 
llvm-svn: 66660

Duncan Sands be69d60d54 Add parentheses to pacify gcc-4.3. 
llvm-svn: 66653
 2009-03-11 09:04:34 +00:00
Duncan Sands e2881053c9 Remove the one-definition-rule version of extern_weak 
linkage: this linkage type only applies to declarations,
but ODR is only relevant to globals with definitions.

llvm-svn: 66650
 2009-03-11 08:08:06 +00:00
Nate Begeman 664cf27602 Allow cross-process JIT to handle MachineRelocations of the ExternalSymbol 
variety.  For example, an i64 div might turn into a call to __divdi3 during
legalization.

llvm-svn: 66646
 2009-03-11 07:03:43 +00:00
Mon P Wang ce6a26cb1a Fixed a v8i16 shuffle case that should generate a pshufb instead of a pshuflw/hw. 
llvm-svn: 66645
 2009-03-11 06:35:11 +00:00
Chris Lattner 248ad00afd formatting change, reduce indentation. No functionality change. 
llvm-svn: 66642
 2009-03-11 05:48:52 +00:00
Chris Lattner 43d6377f89 reapply my previous patch (r66358) with a tweak to set the 
alignment of the generated constant pool entry to the
desired alignment of a type.  If we don't do this, we end up
trying to do movsd from 4-byte alignment memory.  This fixes
450.soplex and 456.hmmer.

llvm-svn: 66641

Bill Wendling 1df2c1b583 Put the assignment back at the top of this method.

 2009-03-11 00:03:50 +00:00
Evan Cheng 64b3f9d7a7 Two coalescer fixes in one. 
1. Use the same value# to represent unknown values being merged into sub-registers.
2. When coalescer commute an instruction and the destination is a physical register, update its sub-registers by merging in the extended ranges.

llvm-svn: 66610
 2009-03-11 00:03:21 +00:00
Bill Wendling 9621b099af Make ivars private. Other cleanup. No functionality change. 
llvm-svn: 66607
 2009-03-10 23:57:09 +00:00
Mon P Wang 1073de0d73 Changed Allocate to use size_t instead of unsigned. 
llvm-svn: 66602
 2009-03-10 23:48:49 +00:00
Dan Gohman dab7b9355f Add an explicit keyword. 
llvm-svn: 66595

Mon P Wang cc51b03a4e Fixed rounding up EltSize 
llvm-svn: 66594
 2009-03-10 23:04:40 +00:00
Gabor Greif 19393b0064 Give Op<N>() AppleScript-like semantics, i.e. for negative N it indexes relative to op_end. 
This is a preliminary to changes to come. No intended functionality change.

llvm-svn: 66593
 2009-03-10 23:02:13 +00:00
Bill Wendling 86c2656416 Just make the Dwarf timer group static inside of the getter function. No need to alloc/dealloc. 
llvm-svn: 66591
 2009-03-10 22:58:53 +00:00
Bill Wendling b74d650727 Don't put static functions in anonymous namespace. 
llvm-svn: 66589
 2009-03-10 22:36:31 +00:00
Dale Johannesen 900aaa3d1e Don't consider debug intrinsics when checking 
whether a callee to be inlined is a leaf.
