Chris Lattner d861066d15 vector types are simple types. This fixes div/rem of vectors. 
llvm-svn: 47807
 2008-03-02 03:33:31 +00:00
Chris Lattner b104be599a Print vector types appropriately. This gets basic vector code working 
(PR1126)

Nick Lewycky 3cc9be0b59 Add an unwind_to field to basic blocks, making them Users instead of Values. 
This is the first checkin for PR1269, the new EH infrastructure.

llvm-svn: 47796
 2008-03-01 17:20:55 +00:00
Andrew Lenharth 0070dd1de3 Add lock prefix support to x86. Also add the instructions necessary for the atomic ops. They are still marked pseudo, since I cannot figure out what format to use, but they are the correct opcode. 
llvm-svn: 47795
 2008-03-01 13:37:02 +00:00
Chris Lattner ffe0da0eb2 Fix PR2113 by verifying allocations. 
llvm-svn: 47792
 2008-03-01 09:01:57 +00:00
Chris Lattner a683edb2d8 allow specified inline threshold to be negative, as the value is 
itself sometimes negative.

 2008-03-01 08:09:51 +00:00
Dale Johannesen 208cc8f1b9 Add MVT::is128BitVector and is64BitVector. Shrink 
unaligned load/store code using them.  Per review
of unaligned load/store vector patch.

Evan Cheng 73bdf043a1 Refactor / clean up code; remove td list scheduler special tie breaker (no real benefit).

Devang Patel e8ddaba169 Fix cut-n-pasto. 
llvm-svn: 47777
 2008-02-29 23:41:13 +00:00
Devang Patel 4eedfd2421 Add pass to promote sret. 
This pass transforms 

  %struct._Point = type { i32, i32, i32, i32, i32, i32 }
  define internal void @foo(%struct._Point* sret  %agg.result)

into

  %struct._Point = type { i32, i32, i32, i32, i32, i32 }
  define internal %struct._Point @foo()

This pass updates foo() clients appropriately to use
getresult instruction to extract return values.

This pass is not yet ready for prime time.

Bill Wendling 811153a551 If we reload a virtual register that's already been assigned, we want to mark 
that instruction as its "last use". This fixes PR1925.

llvm-svn: 47758
 2008-02-29 18:52:01 +00:00
Evan Cheng 2e26dc8051 Fix PR2112: don't run loop aligner if target doesn't have a TargetLowering object. 
llvm-svn: 47755
 2008-02-29 17:52:15 +00:00
Chris Lattner c966cebe93 fix a bug Anders ran into where scalarrepl would crash when promoting 
a union containing a vector and an array whose elements were smaller than
the vector elements.  this means we need to compile the load of the 
array elements into an extract element plus a truncate.

Chris Lattner 77205def10 Refactor some code out of ConvertUsesToScalar into their own methods, no 
functionality change.

Evan Cheng ca7c61e79a No need for coalescer to update kills. Only copies are coalesced and those instructions will be deleted. Doh. 
llvm-svn: 47749

Dan Gohman bd2fa566e4 More APInt-ification. 
llvm-svn: 47746
 2008-02-29 01:47:35 +00:00
Dan Gohman 837a6dccd7 Use the new convertFromAPInt instead of convertFromZeroExtendedInteger, 
which allows more of the surrounding arithmetic to be done with APInt
instead of uint64_t.

llvm-svn: 47745

Dan Gohman ec6be4a782 Use the new APInt-enabled form of getConstant instead of converting 
an APInt into a uint64_t to call getConstant.

llvm-svn: 47742
 2008-02-29 01:41:59 +00:00
Dan Gohman 105c1d4106 Add support to APInt for shift and rotate operations with APInt 
instead of uint32_t for the shift/rotate count operand type.

by using the new convertFromAPInt directly.

llvm-svn: 47739
 2008-02-29 01:27:13 +00:00
Dan Gohman 35723eb4f6 Add a method to APFloat to convert directly from APInt. 
llvm-svn: 47738
 2008-02-29 01:26:11 +00:00
Evan Cheng 95a7be473c Added option -align-loops=<true/false> to disable loop aligner pass.

Dale Johannesen cbde4c2206 Interface of getByValTypeAlignment differed between 
generic & x86 versions; change generic to follow x86
and improve comments.  Add PPC version (not right
for non-Darwin.)
