Chris Lattner b3305fb203 When on darwin, compiler_flags need to be percolated down to the 'gcc -r' 
command line so that relinked .o files can be built universal.

Evan Cheng cc7abc6c38 More mov{h|l}p{d|s} patterns. 
llvm-svn: 27836
 2006-04-19 18:20:17 +00:00
Evan Cheng aeb09ccdd3 - More mov{h|l}ps patterns. 
- Increase cost (complexity) of patterns which match mov{h|l}ps ops. These
  are preferred over shufps in most cases.

void foo2(vector float *A, vector float *B) {
  vector float C = (vector float)vec_cmpeq(*A, *B);

Chris Lattner 9754d142a4 Implement an important entry from README_ALTIVEC: 
If an altivec predicate compare is used immediately by a branch, don't
use a (serializing) MFCR instruction to read the CR6 register, which requires
a compare to get it back to CR's.  Instead, just branch on CR6 directly. :)

For example, for:
void foo2(vector float *A, vector float *B) {
  if (!vec_any_eq(*A, *B))
    *B = (vector float){0,0,0,0};
}

We now generate:

_foo2:
        mfspr r2, 256
        oris r5, r2, 12288
        mtspr 256, r5
        lvx v2, 0, r4
        lvx v3, 0, r3
        vcmpeqfp. v2, v3, v2
        bne cr6, LBB1_2 ; UnifiedReturnBlock
LBB1_1: ; cond_true
        vxor v2, v2, v2
        stvx v2, 0, r4
        mtspr 256, r2
        blr
LBB1_2: ; UnifiedReturnBlock
        mtspr 256, r2
        blr

instead of:

_foo2:
        mfspr r2, 256
        oris r5, r2, 12288
        mtspr 256, r5
        lvx v2, 0, r4
        lvx v3, 0, r3
        vcmpeqfp. v2, v3, v2
        mfcr r3, 2
        rlwinm r3, r3, 27, 31, 31
        cmpwi cr0, r3, 0
        beq cr0, LBB1_2 ; UnifiedReturnBlock
LBB1_1: ; cond_true
        vxor v2, v2, v2
        stvx v2, 0, r4
        mtspr 256, r2
        blr
LBB1_2: ; UnifiedReturnBlock
        mtspr 256, r2
        blr

This implements CodeGen/PowerPC/vec_br_cmp.ll.

Reid Spencer b687ce80cd Have the AutoRegen.sh script prompt the user for the LLVM src and obj 
directories if it can't find them. Then, replace those values into the
configure.ac script and pass them to the LLVM_CONFIG_PROJECT so that the
values become the default for llvm_src and llvm_obj variables. In this way
the user is required to input this exactly once, and the scripts take it
from there.

 2006-04-18 06:27:47 +00:00
Reid Spencer c81081ab5e Make it possible to default the llvm_src and llvm_obj variables based on 
the arguments to the macro. This better supports the AutoRegen.sh script
in projects/sample/autoconf.

Chris Lattner 96d50487c9 Use vmladduhm to do v8i16 multiplies which is faster and simpler than doing 
even/odd halves.  Thanks to Nate telling me what's what.

Chris Lattner d6d82aa889 Implement v16i8 multiply with this code: 
vmuloub v5, v3, v2
        vmuleub v2, v3, v2
        vperm v2, v2, v5, v4

This implements CodeGen/PowerPC/vec_mul.ll.  With this, v16i8 multiplies are
6.79x faster than before.

Overall, UnitTests/Vector/multiplies.c is now 2.45x faster with LLVM than with
GCC.

Remove the 'integer multiplies' todo from the README file.

Chris Lattner 7e439874cb Lower v8i16 multiply into this code: 
li r5, lo16(LCPI1_0)
        lis r6, ha16(LCPI1_0)
        lvx v4, r6, r5
        vmulouh v5, v3, v2
        vmuleuh v2, v3, v2
        vperm v2, v2, v5, v4

where v4 is:
LCPI1_0:                                        ;  <16 x ubyte>
        .byte   2
        .byte   3
        .byte   18
        .byte   19
        .byte   6
        .byte   7
        .byte   22
        .byte   23
        .byte   10
        .byte   11
        .byte   26
        .byte   27
        .byte   14
        .byte   15
        .byte   30
        .byte   31

This is 5.07x faster on the G5 (measured) than lowering to scalar code +
loads/stores.
