39112023f1 Move synchronizeICache from TargetJITInfo into a static function in JITEmitter.cpp

beeb4e5c8c - Refactor the code that resolve basic block references to a TargetJITInfo 
method.
- Added synchronizeICache() to TargetJITInfo. It is called after each block
  of code is emitted to flush the icache. This ensures correct execution
  on targets that have separate dcache and icache.
- Added PPC / Mac OS X specific code to do icache flushing.

a6c9288186 Added option -code-model to set code model (only used in 64-bit) mode. Valid 
values include small, kernel, medium, large, and default.

07d8ccec50 Instructions with variable operands (variable_ops) can have a number required 
operands. e.g.
def CALL32r : I<0xFF, MRM2r, (ops GR32:$dst, variable_ops),
                "call {*}$dst", [(X86call GR32:$dst)]>;
TableGen should emit operand informations for the "required" operands.

Added a target instruction info flag M_VARIABLE_OPS to indicate the target
instruction may have more operands in addition to the minimum required
operands.

574d4e6992 For PR786: 
Minor tweaks in public headers and a few .cpp files so that LLVM can build
successfully with -pedantic and projects using LLVM with -pedantic don't
get warnings from LLVM. There's still more -pedantic warnings to fix.

 2006-05-23 18:18:46 +00:00
Evan Cheng
86e56c1066 Added option -enable-finite-only-fp-math. When on, the codegen can assume that 
FP arithmetic arguments and results are never NaNs or +=Infs. This includes
ignoring parity flag (PF) when checking for FP equality.

29e4d70aed Refactor a bunch of includes so that TargetMachine.h doesn't have to include 
TargetData.h.  This should make recompiles a bit faster with my current
TargetData tinkering.

71bc529dfa Refactor TargetMachine, pushing handling of TargetData into the target-specific subclasses. This has one caller-visible change: getTargetData() now returns a pointer instead of a reference. 
This fixes PR 759.

ec4d1668ef Added a virtual method isVectorClearMaskLegal to TLI. It is similar to 
isShuffleMaskLegal, used to determine if it makes sense to turn a
"vector clear" (e.g. pand V, <0, -1, 0, -1> to a shuffle of the vector and
a zero vector.
