 2009-03-30 15:28:00 +00:00
Anton Korobeynikov 7c5f3c40ca Do not propagate ELF-specific stuff (data.rel) into other targets. This simplifies code and also ensures correctness.

Anton Korobeynikov f3cf04f900 Testcase for recent ro/relocs stuff 
llvm-svn: 68008
 2009-03-29 17:14:57 +00:00
Anton Korobeynikov bea241a5f5 IA64 is as weird as Alpha wrt r/o relocs :) 
llvm-svn: 68007
 2009-03-29 17:14:35 +00:00
Anton Korobeynikov 014a86f216 Alpha always requires global relocations to be r/w regardless of PIC.

Anton Korobeynikov 088ebede53 Honour relocation behaviour stuff for ro objects 
llvm-svn: 68005
 2009-03-29 17:13:49 +00:00
Anton Korobeynikov 7437b59caf Extend the relocation tracker handler, so we can filter on different 'kinds' of relocations required.

Duncan Sands d21581eaa1 Fix PR3899: add support for extracting floats from vectors

Based on a patch by Jakob Stoklund Olesen.

 2009-03-29 07:03:30 +00:00
Chris Lattner e50f47971b When forming sentinels for empty/tombstone, make sure to respect the 
pointer's expected number of zero low-bits.

This should fix the breakage I introduced recently.

llvm-svn: 67990
 2009-03-29 06:33:22 +00:00
Chris Lattner 3a6dc751ac add helper method. 
llvm-svn: 67989
 2009-03-29 06:32:46 +00:00
Chris Lattner a9c6de15fb Add a simple type-safe bit-mangling pointer union class. This allows 
you to do things like:

  ///    PointerUnion<int*, float*> P;
  ///    P = (int*)0;
  ///    printf("%d %d", P.is<int*>(), P.is<float*>()); // prints "1 0"
  ///    X = P.get<int*>();     // ok.
  ///    Y = P.get<float*>();   // runtime assertion failure.
  ///    Z = P.get<double*>();  // does not compile.
  ///    P = (float*)0;
  ///    Y = P.get<float*>();   // ok.
  ///    X = P.get<int*>();     // runtime assertion failure.

 2009-03-29 06:06:02 +00:00
Chris Lattner 35c0232cb0 Allow a specific PointerIntPair instance to use a specific Pointer trait: 
some pointer instances have properties that not all of a type have.

llvm-svn: 67986
 2009-03-29 06:02:20 +00:00
Chris Lattner d4ff5fce81 Add a PointerLikeTypeTraits specialization for uintptr_t 
llvm-svn: 67985
 2009-03-29 06:00:21 +00:00
Chris Lattner 9bb25a192a Value* only has 2 bits free as well. 
llvm-svn: 67984
 2009-03-29 05:45:43 +00:00
Chris Lattner eb71b17705 Replace the PointerLikeTypeTraits::getNumLowBitsAvailable 
function with a new NumLowBitsAvailable enum, which makes the
value available as an integer constant expression.

Add PointerLikeTypeTraits specializations for Instruction* and
Use** since they are only guaranteed 4-byte aligned.

Enhance PointerIntPair to know about (and enforce) the alignment
specified by PointerLikeTypeTraits.  This should allow things 
like PointerIntPair<PointerIntPair<void*, 1,bool>, 1, bool> 
because the inner one knows that 2 low bits are free.

llvm-svn: 67979
 2009-03-29 04:32:37 +00:00
Chris Lattner a00f0d7e4c rename PointerLikeTypeInto to PointerLikeTypeTraits, add trait for 
# low bits free, and move to its own header.

llvm-svn: 67973
 2009-03-29 00:39:30 +00:00
Chris Lattner 8eda11bd9d now that you can put a PointerIntPair in a SmallPtrSet, remove some 
hackish workarounds from memdep

llvm-svn: 67971
 2009-03-29 00:24:04 +00:00
Chris Lattner dc2999b4df teach SmallPtrSet that PointerIntPair is "basically a pointer". 
llvm-svn: 67970
 2009-03-29 00:18:42 +00:00
Chris Lattner 356d974a93 add a note

Rafael Espindola 1f11c3c36f Use array_lengthof 
llvm-svn: 67950
 2009-03-28 19:02:18 +00:00
Rafael Espindola 6ff3dabbb4 Have only one definition of X86AddrNumOperands. 
llvm-svn: 67949
 2009-03-28 18:55:31 +00:00
Rafael Espindola c2a17d3022 Make code a bit less brittle by no hardcoding the number 
of operands in an address in so many places.

llvm-svn: 67945
 2009-03-28 17:03:24 +00:00
Arnold Schwaighofer e622cbf385 Make check in CheckTailCallReturnConstraints for ignorable instructions between 
a CALL and a RET node more generic. Add a test for tail calls with a void
return.

llvm-svn: 67943
 2009-03-28 12:36:29 +00:00
Bill Wendling c619aaf122 Update the Visual Studio docs. Patch by Stefanus! 
llvm-svn: 67940
 2009-03-28 10:24:15 +00:00
Arnold Schwaighofer 83d5420d02 Enable tail call optimization for functions that return a struct (bug 3664) and for functions that return types that need extending (e.g i1). 
llvm-svn: 67934
 2009-03-28 08:33:27 +00:00
Chris Lattner 0527eda02e declare everything as class to avoid angering the VC++ gods. 
llvm-svn: 67931
 2009-03-28 07:48:03 +00:00
Chris Lattner dec48eab86 add a traits class for SmallPtrSet that allows us to stick things that are 
"basically pointers" into it.

llvm-svn: 67930
 2009-03-28 07:44:53 +00:00
Evan Cheng fd81c73cde Optimize some 64-bit multiplication by constants into two lea's or one lea + shl since imulq is slow (latency 5). e.g. 
x * 40
=>
shlq    $3, %rdi
leaq    (%rdi,%rdi,4), %rax

This has the added benefit of allowing more multiply to be folded into addressing mode. e.g.
a * 24 + b
=>
leaq    (%rdi,%rdi,2), %rax
leaq    (%rsi,%rax,8), %rax

llvm-svn: 67917
 2009-03-28 05:57:29 +00:00
Chris Lattner 7516668998 move a large method out of line.

Dan Gohman 2785e4be37 Fix what surely must be a copy+pasto. 
llvm-svn: 67881
 2009-03-27 23:55:04 +00:00
Dan Gohman 6d75876473 Initialize LiveOutInfo's APInt members to zero, as APInt's 
default constructor produces an uninitialized APInt.
This fixes PR3896.

Julien Lerouge 15833b93cf Fix build on MacOS 10.4 systems (suggested by Mike Smith). 
llvm-svn: 67855
 2009-03-27 18:18:00 +00:00
Dan Gohman 3f50cb6cd4 Fix this test so that it doesn't spuriously fail due to some 
unrelated debugging output happening to contain the string "store".
