Nate Begeman 69df6132d7 First pass at supporting relocations. Relocations are written correctly to 
the file now, however the relocated address is currently wrong.  Fixing
that will require some deep pondering.

Evan Cheng de33f66286 Fixed a FuseTwoAddrInst() bug: consider GlobalAddress and JumpTableIndex 
in addition to immediate operands.

Chris Lattner b2e7316b2d Non-allocatable physregs can be killed and dead, but don't treat them as 
safe for later allocation.  This fixes McCat/18-imp with llc-beta.

 2006-09-08 19:11:11 +00:00
Chris Lattner 9b1a6ebf20 Fix a bunch of llc-beta failures on x86 yesterday. Don't allow selection 
of unallocatable registers, just because an alias is allocatable.  We were
picking registers like SIL just because ESI was being used.

llvm-svn: 30172
 2006-09-08 01:54:32 +00:00
Evan Cheng 89c5d04b9b - Identify a vector_shuffle that can be turned into an undef, e.g. 
shuffle V1, <undef>, <undef, undef, 4, 5>
- Fix some suspicious logic into LowerVectorShuffle that cause less than
  optimal code by failing to identify MOVL (move to lowest element of a
  vector).

Chris Lattner b9e0a9e82f Fix a cross-build issue. The asmsyntax shouldn't be affected by the build 
host, it should be affected by the target.  Allow the command line option to
override in either case.

Devang Patel 5606dd8a45 Using addPassesToEmitWholeFile is not a good idea here. 
Use FunctionPassManager to do the job.

Chris Lattner c465046e65 Throttle back tail duplication to avoid creating really ugly sequences of code. 
For Transforms/TailDup/if-tail-dup.ll, f.e., it produces:

_foo:
        movl 8(%esp), %eax
        movl 4(%esp), %ecx
        testl $1, %ecx
        je LBB1_2       #cond_next
LBB1_1: #cond_true
        movl $1, (%eax)
LBB1_2: #cond_next
        testl $2, %ecx
        je LBB1_4       #cond_next10
LBB1_3: #cond_true6
        movl $1, 4(%eax)
LBB1_4: #cond_next10
        testl $4, %ecx
        je LBB1_6       #cond_next18
LBB1_5: #cond_true14
        movl $1, 8(%eax)
LBB1_6: #cond_next18
        testl $8, %ecx
        je LBB1_8       #return
LBB1_7: #cond_true22
        movl $1, 12(%eax)
        ret
LBB1_8: #return
        ret

instead of:

_foo:
        movl 4(%esp), %eax
        testl $2, %eax
        sete %cl
        movl 8(%esp), %edx
        testl $1, %eax
        je LBB1_2       #cond_next
LBB1_1: #cond_true
        movl $1, (%edx)
        testb %cl, %cl
        jne LBB1_4      #cond_next10
        jmp LBB1_3      #cond_true6
LBB1_2: #cond_next
        testb %cl, %cl
        jne LBB1_4      #cond_next10
LBB1_3: #cond_true6
        movl $1, 4(%edx)
        testl $4, %eax

        je LBB1_6       #cond_next18
LBB1_5: #cond_true14
        movl $1, 8(%edx)
        testl $8, %eax
        je LBB1_8       #return
        jmp LBB1_7      #cond_true22
LBB1_6: #cond_next18
        testl $8, %eax
        je LBB1_8       #return

Chris Lattner dc22b97b9a new testcase 
llvm-svn: 30157
 2006-09-07 21:29:32 +00:00
Chris Lattner dc4ff5311f Eliminate X86ISD::TEST, using X86ISD::CMP instead. Match X86ISD::CMP patterns 
using test, which provides nice simplifications like:

-       movl %edi, %ecx
-       andl $2, %ecx
-       cmpl $0, %ecx
+       testl $2, %edi
        je LBB1_11      #cond_next90

There are a couple of dagiselemitter deficiencies that this exposes, they will
be handled later.
