Chris Lattner 9834ad2fc6 Instead of li/xoris use li/oris. Note that this doesn't work if bit 15 is 
set, so disable the pattern in that case.

Chris Lattner 7e742e46ac Add some 64-bit logical ops. 
Split imm16Shifted into a sext/zext form for 64-bit support.
Add some patterns for immediate formation.  For example, we now compile this:

static unsigned long long Y;
void test3() {
  Y = 0xF0F00F00;
}

into:

_test3:
        li r2, 3840
        lis r3, ha16(_Y)
        xoris r2, r2, 61680
        std r2, lo16(_Y)(r3)
        blr

GCC produces:

_test3:
        li r0,0
        lis r2,ha16(_Y)
        ori r0,r0,61680
        sldi r0,r0,16
        ori r0,r0,3840
        std r0,lo16(_Y)(r2)
        blr

Chris Lattner 2d4e8f7e86 Add some patterns for globals, so we can now compile this: 
static unsigned long long X, Y;
void test1() {
  X = Y;
}

into:

_test1:
        lis r2, ha16(_Y)
        lis r3, ha16(_X)
        ld r2, lo16(_Y)(r2)
        std r2, lo16(_X)(r3)

Chris Lattner a5190ae7a9 fix some assumptions that pointers can only be 32-bits. With this, we can 
now compile:

static unsigned long X;
void test1() {
  X = 0;
}

into:

_test1:
        lis r2, ha16(_X)
        li r3, 0
        stw r3, lo16(_X)(r2)
        blr

Totally amazing :)

Chris Lattner f3b5b92e58 Don't pass target name into TargetData anymore, it is never used or needed. 
Remove explicit casts to std::string now that there is no overload resolution
issues in the TargetData ctors.

Chris Lattner 16682fff2b Document the subtarget features better, make sure that 64-bit mode, 64-bit 
support, and 64-bit register use are all consistent with each other.

Add a new "IsPPC" feature, to distinguish ppc32 vs ppc64 targets, use this
to configure TargetData differently.  This not makes ppc64 blow up on lots
of stuff :)

llvm-svn: 28825
 2006-06-16 17:50:12 +00:00
Chris Lattner a35f306740 Rename some subtarget features. A CPU now can *have* 64-bit instructions, 
can in 32-bit mode we can choose to optionally *use* 64-bit registers.

llvm-svn: 28824
 2006-06-16 17:34:12 +00:00
Chris Lattner 0c4aa14deb First baby step towards ppc64 support. This adds a new -march=ppc64 backend 
that is currently just like ppc32 :)

Chris Lattner c5bb8ab1d5 Port some bugfixes in shift handling from SimplifyDemandedBits over to 
ComputeMaskedBits.  DemandedMasks and KnownZero/One masks should never have
bits set out of the range of the base datatype.

llvm-svn: 28768

Chris Lattner ac59ab515a Gaar! Don't use r11 for CR save/restore, use R0. R11 can be register

 2006-06-10 01:15:02 +00:00
Chris Lattner 006b2c6ab9 Fix a problem exposed by the local allocator. CALL instructions are not marked 
as using incoming argument registers, so the local allocator would clobber them
between their set and use.  To fix this, we give the call instructions a variable
number of uses in the CALL MachineInstr itself, so live variables understands
the live ranges of these register arguments.
