Chris Lattner 3ffd238f1c reduce nesting by rearranging branches. 
llvm-svn: 75110
 2009-07-09 05:55:04 +00:00
Chris Lattner e0dae0e716 make isel use MO_PIC_BASE_OFFSET when lowering globalvalues on darwin in pic 
mode, instead of having asmprinter just "know" to print them.

llvm-svn: 75109
 2009-07-09 05:47:33 +00:00
Chris Lattner 0667b145c4 various minor cleanups, no functionality change. 
llvm-svn: 75108
 2009-07-09 05:42:07 +00:00
Chris Lattner d047d06358 make isel decide whether to emit $stub's on darwin instead of asmprinter. 
llvm-svn: 75107
 2009-07-09 05:27:35 +00:00
Chris Lattner 3e41fec4df pc-relative references are *always* to functions, never to globals. ISel 
is incapable of lowering direct references to globals like this, zap the code.

 2009-07-09 05:19:23 +00:00
Chris Lattner 82aa63c9b0 make cygwin use its own stubs set, instead of overloading a darwin one. 
llvm-svn: 75105
 2009-07-09 05:09:24 +00:00
Chris Lattner d5d80ab6b6 Make isel determine where to emit PLT-relative calls instead of having 
asmprinter do it.

llvm-svn: 75104
 2009-07-09 05:02:21 +00:00
Chris Lattner 1f981f05af add missing predicate. 
llvm-svn: 75103
 2009-07-09 04:56:23 +00:00
Chris Lattner b4de36ea47 isPICStyleStub() is now never true in -static mode, so simplify code. 
llvm-svn: 75102
 2009-07-09 04:43:12 +00:00
Chris Lattner fef11d6e77 simplify some code based on the fact that picstyles != none are only valid 
in pic or dynamic-no-pic mode. Also, x86-64 never used picstylegot.

llvm-svn: 75101
 2009-07-09 04:39:06 +00:00
Chris Lattner 62f568c037 all this logic always returns true because GOT mode is never active in x86-64 mode. 
Simplify it away, someone should evaluate this.

llvm-svn: 75100
 2009-07-09 04:27:47 +00:00
Chris Lattner 3945dd0c44 isPICStyleRIPRel() and friends are never true in -static mode. 
Simplify code based on this.

Nick Lewycky 4e705e421c Move PR4517 to README.txt. 
llvm-svn: 75098
 2009-07-09 04:03:30 +00:00
Lang Hames dab7b06de9 Improved tracking of value number kills. VN kills are now represented 
as an (index,bool) pair. The bool flag records whether the kill is a
PHI kill or not. This code will be used to enable splitting of live
intervals containing PHI-kills.

A slight change to live interval weights introduced an extra spill
into lsr-code-insertion (outside the critical sections). The test 
condition has been updated to reflect this.

 2009-07-09 03:57:02 +00:00
Chris Lattner 117608b129 .o file writing shouldn't mess around with pic/relo models like the JIT does. 
llvm-svn: 75096
 2009-07-09 03:40:30 +00:00
Chris Lattner 0b0c5cc376 move a hack out of the asm-printer specific path to the main target selection path. 
llvm-svn: 75095
 2009-07-09 03:37:30 +00:00
Chris Lattner 7e3abf1ab0 many more cleanups, for example if in the "none" pic-style, 
make sure we're set to static codegen.  Simplify the decision
tree of target->picstyle/picmode settings.

llvm-svn: 75094
 2009-07-09 03:32:31 +00:00
Chris Lattner 821084a356 Reduce indentation in GVRequiresExtraLoad. Return true for windows 
with DLLImport symbols even when in -static mode.

llvm-svn: 75093
 2009-07-09 03:27:27 +00:00
Chris Lattner 1c5bf9d26d When in -static mode, force the PIC style to none. Doing this requires fixing 
code which conflated RIPRel PIC with x86-64.  Fix these to just check for X86-64
directly.

llvm-svn: 75092
 2009-07-09 03:15:51 +00:00
Chris Lattner 384a738b4a merge two identical functions and simplify things that are GOT specific 
llvm-svn: 75091
 2009-07-09 02:55:47 +00:00
Chris Lattner 4d1e9bf717 hoist check for IsTailCall to callers. Eliminate redundant check for 
x86-64: GOT-style PIC is never used on x86-64.

llvm-svn: 75090
 2009-07-09 02:46:53 +00:00
Chris Lattner 88765d4831 change a few methods to be static functions.

Chris Lattner 47f64ea174 move handling of dllimport linkage in isel, not in asmprinter. 
llvm-svn: 75086
 2009-07-09 00:58:53 +00:00
Chris Lattner 212f44d180 we have no tests for dllimport/export. Add one.

llvm-svn: 75083

Dan Gohman 6b04136756 Make SelectionDAG::getVectorShuffle work properly for VECTOR_SHUFFLE 
nodes with operand types that differ from the result type. (This
doesn't normally happen right now, because
SelectionDAGLowering::visitShuffleVector normalizes vector shuffles.)

Chris Lattner 031c5fec43 remove "asmcall", using print_pcrel_imm instead of printOperand.

Chris Lattner ade55bc8dd * add some assertions for sanity checking. 
* remove some old code that was needed when we'd put ESP in the scale instead of 
  the base of some instructions.
* Fix a bug with the P modifier in inline asm that caused us to drop it.

Anders Carlsson 03f89b1828 Store the isAddressOfOperand in the UnresolvedDeclRefExpr, so that we can pass it when instantiating the expr. Fixes another member pointer bug.

Douglas Gregor b257e4fff8 Implement the simple form of overload resolution used when taking the 
address of an overloaded function (which may involve both functions
and function templates).

Evan Cheng 5edd90cbbc - Add some NEON ld / st instruction static encoding. 
- Make bits 25-27 for ldrh, etc. explicitly zero. Previously only the JIT uses the encoding information and it's assuming anything not specified to be zero. Making them explicit so the disassembler is happy.
Patch by Sean Callanan.

Jeffrey Yasskin 70415d97a8 Add an option to allocate JITed global data separately from code. By 
default, this option is not enabled to support clients who rely on
this behavior.

Fixes http://llvm.org/PR4483

A patch to allocate additional memory for globals after we run out is
forthcoming.
