Reid Spencer aba0cc7173 Make the %"..." syntax legal for local name. This just makes it symmetric

Chris Lattner a655a157a0 Fix Transforms/InstCombine/2007-05-18-CastFoldBug.ll, a bug that devastates 
objc code due to the way the FE lowers objc message sends.

Reid Spencer 80fcb754d9 On Linux platforms and at optimization levels -O1 and above, llvm-gcc can 
turn "putchar" calls into _IO_putc calls which is a lower-level interface.
This patch allows these calls to be executed by lli in interpreter mode.

Chris Lattner e8bd53c36a Handle negative strides much more optimally. This compiles X86/lsr-negative-stride.ll 
into:

_t:
        movl 8(%esp), %ecx
        movl 4(%esp), %eax
        cmpl %ecx, %eax
        je LBB1_3       #bb17
LBB1_1: #bb
        cmpl %ecx, %eax
        jg LBB1_4       #cond_true
LBB1_2: #cond_false
        subl %eax, %ecx
        cmpl %ecx, %eax
        jne LBB1_1      #bb
LBB1_3: #bb17
        ret
LBB1_4: #cond_true
        subl %ecx, %eax
        cmpl %ecx, %eax
        jne LBB1_1      #bb
        jmp LBB1_3      #bb17

instead of:

_t:
        subl $4, %esp
        movl %esi, (%esp)
        movl 12(%esp), %ecx
        movl 8(%esp), %eax
        cmpl %ecx, %eax
        je LBB1_4       #bb17
LBB1_1: #bb.outer
        movl %ecx, %edx
        negl %edx
LBB1_2: #bb
        cmpl %ecx, %eax
        jle LBB1_5      #cond_false
LBB1_3: #cond_true
        addl %edx, %eax
        cmpl %ecx, %eax
        jne LBB1_2      #bb
LBB1_4: #bb17
        movl (%esp), %esi
        addl $4, %esp
        ret
LBB1_5: #cond_false
        movl %ecx, %edx

Chris Lattner b08cbbd737 Disable the (A == (B-A)) -> 2*A == B xform when the sub has multiple uses (in 
this case, the xform introduces an extra operation).  This compiles
PowerPC/compare-duplicate.ll into:

_test:
        subf r2, r3, r4
        cmplw cr0, r2, r3
        bne cr0, LBB1_2 ;F

instead of:

_test:
        slwi r2, r3, 1
        subf r3, r3, r4
        cmplw cr0, r4, r2
        bne cr0, LBB1_2 ;F

This is target independent of course.

Reid Spencer b6af1aae35 Fix an assertion introduced by my last change to the toString method. We 
can't use getZExtValue() to extract the low order bits for each digit.
Instead, we need to access the low order word directly.
