Chris Lattner 940cc978ef Remove a bunch more SparcV9 specific stuff 
llvm-svn: 28093
 2006-05-04 01:15:02 +00:00
Chris Lattner 9f6639b64d Remove some more unused stuff from MachineInstr that was leftover from V9.

Owen Anderson 20a631fde7 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.

Nate Begeman 287dc5be0d Hooray, everyone now uses the same printBasicBlockLabel implementation 
llvm-svn: 28056
 2006-05-02 17:34:51 +00:00
Nate Begeman b9d4f8324d Extend printBasicBlockLabel a bit so that it can be used to print all 
basic block labels, consolidating the code to do so in one place for each
target.

Nate Begeman 4ca2ea5b43 JumpTable support! What this represents is working asm and jit support for 
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

Jim Laskey c0d6518f27 Make sure that debug labels are defined within the same section and after the 
entry point of a function.

Chris Lattner 2771e2c960 Codegen things like: 
<int -1, int -1, int -1, int -1>
and
 <int 65537, int 65537, int 65537, int 65537>

Using things like:
  vspltisb v0, -1
and:
  vspltish v0, 1

instead of using constant pool loads.

This implements CodeGen/PowerPC/vec_splat.ll:splat_imm_i{32|16}.

Chris Lattner 77373d1bea Add support for "ri" addressing modes where the immediate is a 14-bit field 
which is shifted left two bits before use.  Instructions like STD use this
addressing mode.

Chris Lattner 139eac5b71 Print absolute memory references like this: 
lwz r2, 8(0)
instead of this:
       lwz r2, 8(r0)

This fixes the llc/llc-beta failures on PPC last night.

inline asms! :)

Chris Lattner 1bad2546d0 Implement the PPC inline asm "L" modifier. This allows us to compile: 
long long test(long long X) {
  __asm__("foo %0 %L0 %1 %L1" : "=r"(X): "r"(X));
  return X;
}

to:
        foo r2 r3 r2 r3

Evan Cheng 73136dfecc - Added option -relocation-model to set relocation model. Valid values include static, pic, 
dynamic-no-pic, and default.
PPC and x86 default is dynamic-no-pic for Darwin, pic for others.
- Removed options -enable-pic and -ppc-static.

Chris Lattner b134520b86 If we have zero initialized data with external linkage, use .zerofill to 
emit it (instead of .space), saving a bit of space in the .o file.

For example:
int foo[100];
int bar[100] = {};

when compiled with C++ or -fno-common results in shrinkage from 1160 to 360
bytes of space.  The X86 backend can also do this on darwin.

Chris Lattner 1b1a8731c0 Use the asmprinter to find out what the preferred alignment of a global is. 
This patch speeds up 172.mgrid from 31.81s to 11.39s on darwin/ppc.
Many many thanks to Nate for tracking down the root cause of the issue.

Jim Laskey 219d559824 Applied some recommend changes from sabre. The dominate one beginning "let the 
pass manager do it's thing."  Fixes crash when compiling -g files and suppresses
dwarf statements if no debug info is present.

 2005-12-22 21:15:17 +00:00
Nate Begeman c126397a69 Fix a couple of the FIXMEs, thanks to suggestion from Chris. This allows 
us to load and store vectors directly at a pointer (offset of zero) by
using r0 as the base register.  This also requires some asm printer work
to satisfy the darwin assembler.

For
void %foo(<4 x float> * %a) {
entry:
  %tmp1 = load <4 x float> * %a;
  %tmp2 = add <4 x float> %tmp1, %tmp1
  store <4 x float> %tmp2, <4 x float> *%a
  ret void
}

We now produce:
_foo:
        lvx v0, 0, r3
        vaddfp v0, v0, v0
        stvx v0, 0, r3
        blr

Instead of:
_foo:
        li r2, 0
        lvx v0, r2, r3
        vaddfp v0, v0, v0
        stvx v0, r2, r3
        blr

Nate Begeman 6f8c1ace6e No longer track value types for asm printer operands, and remove them as
