55343065e3 remove MachineOpCode typedef. 
llvm-svn: 45679
 2008-01-07 02:48:55 +00:00
Chris Lattner
f7f96d818f Rename MachineInstr::getInstrDescriptor -> getDesc(), which reflects 
that it is cheap and efficient to get.

Move a variety of predicates from TargetInstrInfo into 
TargetInstrDescriptor, which makes it much easier to query a predicate
when you don't have TII around.  Now you can use MI->getDesc()->isBranch()
instead of going through TII, and this is much more efficient anyway. Not
all of the predicates have been moved over yet.

Update old code that used MI->getInstrDescriptor()->Flags to use the
new predicates in many places.

8b4b75c771 Change the 'isStore' inferrer to look for 'SDNPMayStore' 
instead of "ISD::STORE".  This allows us to mark target-specific dag
nodes as storing (such as ppc byteswap stores).  This allows us to remove
more explicit isStore flags from the .td files.

Finally, add a warning for when a .td file contains an explicit 
isStore and tblgen is able to infer it.

1285ec2ae7 Fix a problem where lib/Target/TargetInstrInfo.h would include and use 
a header file from libcodegen.  This violates a layering order: codegen
depends on target, not the other way around.  The fix to this is to 
split TII into two classes, TII and TargetInstrInfoImpl, which defines
stuff that depends on libcodegen.  It is defined in libcodegen, where 
the base is not.

96167aa93c Rename SSARegMap -> MachineRegisterInfo in keeping with the idea 
that "machine" classes are used to represent the current state of
the code being compiled.  Given this expanded name, we can start 
moving other stuff into it.  For now, move the UsedPhysRegs and
LiveIn/LoveOuts vectors from MachineFunction into it.

Update all the clients to match.

This also reduces some needless #includes, such as MachineModuleInfo
from MachineFunction.

9e5cc35593 Add new shorter predicates for testing machine operands for various types: 
e.g. MO.isMBB() instead of MO.isMachineBasicBlock().  I don't plan on 
switching everything over, so new clients should just start using the 
shorter names.

Remove old long accessors, switching everything over to use the short
accessor: getMachineBasicBlock() -> getMBB(), 
getConstantPoolIndex() -> getIndex(), setMachineBasicBlock -> setMBB(), etc.

f93ea63eaa Enable EH on PPC Darwin. This basically works; there 
are a couple of issues that show up with the optimizer,
but I don't think they're really EH problems.
(llvm-gcc testsuite users note:  By default the testsuite
uses the unwinding code that's built as part of your local
llvm-gcc, which does not work.  You need to trick it into
using the installed system unwinding code to get useful
results.)

e93a775a4d Fix a significant code quality regression I introduced on PPC64 quite

	ld r2, 16(r1)
	std r2, 0(r3)
	ld r0, 16(r1)
	mtlr r0
	blr 

instead of:

_foo:
	mflr r0
	std r0, 16(r1)
	lis r0, 0
	ori r0, r0, 16
	ldx r2, r1, r0
	std r2, 0(r3)
	ld r0, 16(r1)
	mtlr r0
	blr 

for:

void foo(void **X) {
  *X = __builtin_return_address(0);
}

Bill Wendling
cc75435ebf Unify CALLSEQ_{START,END}. They take 4 parameters: the chain, two stack 
adjustment fields, and an optional flag. If there is a "dynamic_stackalloc" in
the code, make sure that it's bracketed by CALLSEQ_START and CALLSEQ_END. If
not, then there is the potential for the stack to be changed while the stack's
being used by another instruction (like a call).

This can only result in tears...

d1bdbd010b Eliminate the remaining uses of getTypeSize. This 
should only effect x86 when using long double.  Now
12/16 bytes are output for long double globals (the
exact amount depends on the alignment).  This brings
globals in line with the rest of LLVM: the space
reserved for an object is now always the ABI size.
One tricky point is that only 10 bytes should be
output for long double if it is a field in a packed
struct, which is the reason for the additional
argument to EmitGlobalConstant.

5635277c36 Long live the exception handling! 
This patch fills the last necessary bits to enable exceptions
handling in LLVM. Currently only on x86-32/linux.

In fact, this patch adds necessary intrinsics (and their lowering) which
represent really weird target-specific gcc builtins used inside unwinder.

After corresponding llvm-gcc patch will land (easy) exceptions should be
more or less workable. However, exceptions handling support should not be 
thought as 'finished': I expect many small and not so small glitches
everywhere.

dbce9ef4b8 Fix a bug which caused us to never be able to use signed comparisons for 
equality comparisons of a constant.  This allows us to codegen the 'sintzero'
loop in PR1288 as:

LBB1_1: ;cond_next
        li r4, 0
        addi r2, r2, 1
        stw r4, 0(r3)
        addi r3, r3, 4
        cmpwi cr0, r2, -1
        bne cr0, LBB1_1 ;cond_next

instead of:

LBB1_1: ;cond_next
        addi r2, r2, 1
        li r4, 0
        xoris r5, r2, 65535
        stw r4, 0(r3)
        addi r3, r3, 4
        cmplwi cr0, r5, 65535
        bne cr0, LBB1_1 ;cond_next

This implements CodeGen/PowerPC/compare-simm.ll, and also cuts 74

289ab30051 Moved the MachOWriter and ELFWriter out of the Target/* files. Placed the 
definition of it into the CodeGen library. This is so that a backend doesn't
necessarily add in these writers if it doesn't use them (like in the lli
program).

611d5e2eda Propagate changes from my local tree. This patch includes: 
1. New parameter attribute called 'inreg'. It has meaning "place this
parameter in registers, if possible". This is some generalization of
gcc's regparm(n) attribute. It's currently used only in X86-32 backend.
2. Completely rewritten CC handling/lowering code inside X86 backend.
Merged stdcall + c CCs and fastcall + fast CC.
3. Dropped CSRET CC. We cannot add struct return variant for each
target-specific CC (e.g. stdcall + csretcc and so on).
4. Instead of CSRET CC introduced 'sret' parameter attribute. Setting in
on first attribute has meaning 'This is hidden pointer to structure
return. Handle it gently'.
5. Fixed small bug in llvm-extract + add new feature to
FunctionExtraction pass, which relinks all internal-linkaged callees
from deleted function to external linkage. This will allow further
linking everything together.

NOTEs: 1. Documentation will be updated soon.
       2. llvm-upgrade should be improved to translate csret => sret.
          Before this, there will be some unexpected test fails.
