Reid Spencer a94d394ad2 For PR1043: 
This is the final patch for this PR. It implements some minor cleanup
in the use of IntegerType, to wit:
1. Type::getIntegerTypeMask -> IntegerType::getBitMask
2. Type::Int*Ty changed to IntegerType* from Type*
3. ConstantInt::getType() returns IntegerType* now, not Type*

This also fixes PR1120.

Patch by Sheng Zhou.

Evan Cheng df62250cee Modify emission of jump tables on darwin to emit an extra "l" label that 
delimits the boundaries of jump tables.  This lets the linker's dead code
stripping optimization do a better job.

Evan Cheng 97057f37a5 - Target PIC style is no longer affected by relocation model. 
- In x86-64 mode, symbols with external linkage (not just symbols which are
  defined externally) requires GOT indirect reference.
- Stylistic code clean up.

 2007-01-17 17:42:42 +00:00
Anton Korobeynikov 3f6d52834b * Fix one more bug in PIC codegen: extra load is needed for *all* 
non-statics.
* Introduce new option to output zero-initialized data to .bss section.
This can reduce size of binaries. Enable it by default for ELF &
Cygwin/Mingw targets. Probably, Darwin should be also added.

llvm-svn: 33290
 2007-01-17 03:50:41 +00:00
Bill Wendling f758157385 New "TargetObjInfo" class. This holds information that the object writers will 
use to write things to the file. It's abstract so each target should implement
its own version for each writer type.

Bill Wendling c7b2ab9bdf Instead of yet another enum indicating the "assembly language flavor", 
just use the one that's in the subtarget.

Chris Lattner 5488ade154 Fix PR918 by only using typedefs to name struct types. This makes the later 
type ordering stuff work better.  This fixes PR918 and
CodeGen/CBackend/2007-01-15-NamedArrayType.ll

Bill Wendling 0b3a451e1b Make inline ASM the INTEL one if it's in that emission mode. 
llvm-svn: 33247
 2007-01-16 04:13:03 +00:00
Bill Wendling e21237e59a Fix for PR1095: 
LLVM would miscompile ASM dialects when compiling for PPC. Added dialects for
the X86 and PPC backends. It defaults to "0", the first variant of a compound
inline asm expression.

Chris Lattner e76908ba81 add some notes 
llvm-svn: 33228
 2007-01-15 06:25:39 +00:00
Chris Lattner 03c4953cdd rename Type::isIntegral to Type::isInteger, eliminating the old Type::isInteger. 
rename Type::getIntegralTypeMask to Type::getIntegerTypeMask.

This makes naming much more consistent.  For example, there are now no longer any
instances of IntegerType that are not considered isInteger! :)

llvm-svn: 33225
 2007-01-15 02:27:26 +00:00
Chris Lattner f448a8c8ac Make use of isInteger vs isIntegral more explicit

Chris Lattner 9f6badbc41 add a new HiddenDirective member for handling visibility. 
llvm-svn: 33197
 2007-01-14 06:27:21 +00:00
Chris Lattner ae5db00419 add a missing else. This caused globals to be printed as: 
movq ___dso_handle@GOTPCREL(%rip)(%rip), %rsi

instead of:
        movq ___dso_handle@GOTPCREL(%rip), %rsi

llvm-svn: 33196
