868f3fb2e0 Implement the --enable-targets= feature of the configure script. The make 
variable TARGETS_TO_BUILD is used to determine which targets in lib/Target
are built and which libraries are linked into llc. This effectively
implements the feature. One item remains: disabling targets in the dejagnu
test suite.

c638ca05a0 Malloc/Free have mod/ref effects. Do not allow CSE of function calls that 
call malloc/free.  This fixes PR555.

8d813a7d51 Handle stores of global address as stores of immediates. Instead of: 
test1:
        movl $N, %eax
        movl %eax, G
        ret

emit:

test1:
        movl $N, G
        ret

706775467b Handle (store &GV -> mem) as a store immediate. This often occurs for 
printf format strings and other stuff.  Instead of generating this:

        movl $l1__2E_str_1, %eax
        movl %eax, (%esp)

we now emit:

        movl $l1__2E_str_1, (%esp)

87fbc1c554 Improve and elimination. On PPC, for: 
bool %test(int %X) {
        %Y = and int %X, 8
        %Z = setne int %Y, 0
        ret bool %Z
}

we now generate this:

        rlwinm r2, r3, 0, 28, 28
        srwi r3, r2, 3

instead of this:

        rlwinm r2, r3, 0, 28, 28
        srwi r2, r2, 3
        rlwinm r3, r2, 0, 31, 31

I'll leave it to Nate to get it down to one instruction. :)

d0a2fda2c6 Fold (x & 8) != 0 and (x & 8) == 8 into (x & 8) >> 3. 
This turns this PPC code:

        rlwinm r2, r3, 0, 28, 28
        cmpwi cr7, r2, 8
        mfcr r2
        rlwinm r3, r2, 31, 31, 31

into this:

        rlwinm r2, r3, 0, 28, 28
        srwi r2, r2, 3
        rlwinm r3, r2, 0, 31, 31

Next up, nuking the extra and.

        %tmp.6 = cast bool %shortcirc_val to int                ; <int> [#uses=1]

into this:

        %tmp.6 = cast bool %shortcirc_val to int                ; <int> [#uses=1]

not this:

        %tmp.6 = select bool %tmp.1, int 1, int %tmp.4.cast             ; <int> [#uses=1]

6ce1b109aa Teach simplifycfg that setcc is cheap and non-trapping, so that it can 
convert this:

        %tmp.1 = seteq int %i, 0                ; <bool> [#uses=1]
        br bool %tmp.1, label %shortcirc_done, label %shortcirc_next

shortcirc_next:         ; preds = %entry
        %tmp.4 = seteq int %j, 0                ; <bool> [#uses=1]
        br label %shortcirc_done

shortcirc_done:         ; preds = %shortcirc_next, %entry
        %shortcirc_val = phi bool [ %tmp.4, %shortcirc_next ], [ true, %entry ]         ; <bool> [#uses=1]

to this:
        %tmp.1 = seteq int %i, 0                ; <bool> [#uses=1]
        %tmp.4 = seteq int %j, 0                ; <bool> [#uses=1]
        %shortcirc_val = select bool %tmp.1, bool true, bool %tmp.4             ; <bool> [#uses=1]

... which is later simplified by instcombine into an or.

Also attempt to use the correct errno to ThrowErrno in situations where
the errno value is erased by subsequent system calls.

145f1ec0a4 Wrap some long lines. 
Make IPSCCP strip off dead constant exprs that are using functions, making
them appear as though their address is taken.  This allows us to propagate
some more pool descriptors, lowering the overhead of pool alloc.
