Anton Korobeynikov 69ff51baa0 Drop obsolete hook and change all usage to new interface

Anton Korobeynikov 8ac1127ed6 SPU section handling is really huge mess. Replace remaining TAI calls for sections with explicit names in order not to block existing backends during section handling migration. SPU folks! Please consider using new section handling facility someday.

Evan Cheng e0add20c1b Properly handle 'm' inline asm constraints. If a GV is being selected for the addressing mode, it requires the same logic for PIC relative addressing, etc.

Devang Patel e87abd26ba Move FN_NOTE_AlwaysInline and other out of ParamAttrs namespace.
Do not check isDeclaration() in hasNote(). It is clients' responsibility.

Dan Gohman 918fe08a56 Arrange for FastISel code to have access to the MachineModuleInfo

Dan Gohman 2430073657 Move the code for initializing the global base reg out of
X86ISelDAGToDAG.cpp and into X86InstrInfo.cpp. This will allow
it to be reused by FastISel.

Chris Lattner f1280cf744 Fold immediates into X86 shifts with fast isel. This generates:
sarl    $3, %ecx

instead of:

movl    $3, %ecx
sarl    %cl, %edx

This shrinks fast isel 176.gcc by about 2000 instructions (.3%)

2008-09-19 23:42:04 +00:00
Dan Gohman 9801ba451a Refactor X86SelectConstAddr, folding it into X86SelectAddress. This
results in better code for globals. Also, unbreak the local CSE for
GlobalValue stub loads.

Dan Gohman 6e005fdc8d Address-mode folding for X86FastISel. It's pretty basic, but it
catches a fair number of common cases. Note that this currently
causes Fast-ISel to leave behind lots of dead instructions.
Those will be dealt with in subsequent commits.

Dan Gohman af13bf1ebd FastISel: For calls, prefer using the callee's address as a constant
over having it in a register. And wait until after checking type
legality before requesting that the callee address be placed in a
register. Also, fix support for calls with void return type.

This speeds up fast-isel isel time by about 15% and reduces
instruction counts by about 3% overall on certain testcases. It also
changes many indirect calls to direct calls.

Dan Gohman 173aa8602d Simplify and generalize X86DAGToDAGISel::CanBeFoldedBy, and draw
up some new ascii art to illustrate what it does. This change
currently has no effect on generated code.

Bill Wendling 95e1af217f Add trampoline support to PPC. GCC simply calls the "__trampoline_setup"
function with appropriate parameters. This allows us to support blocks on PPC.

Bill Wendling 8bc392fb1d - Change "ExternalSymbolSDNode" to "SymbolSDNode".
- Add linkage to SymbolSDNode (default to external).
- Change ISD::ExternalSymbol to ISD::Symbol.
- Change ISD::TargetExternalSymbol to ISD::TargetSymbol

These changes pave the way to allowing SymbolSDNodes with non-external linkage.

Bruno Cardoso Lopes 233785daae Fixed Bug 2751
http://llvm.org/bugs/show_bug.cgi?id=2751

Abicall was enabled even when static code model was provided 
in the command line.
The correct behavior is to disable abicall when static is
specified.

Dan Gohman 38453eebdc Remove isImm(), isReg(), and friends, in favor of
isImmediate(), isRegister(), and friends, to avoid confusion
about having two different names with the same meaning. I'm
not attached to the longer names, and would be ok with
changing to the shorter names if others prefer it.

Dan Gohman d3fe174c53 Define CallSDNode, an SDNode subclass for use with ISD::CALL.
Currently it just holds the calling convention and flags
for isVarArgs and isTailCall.

And it has several utility methods, which eliminate magic
5+2*i and similar index computations in several places.

CallSDNodes are not CSE'd. Teach UpdateNodeOperands to handle
nodes that are not CSE'd gracefully.
