Chris Lattner 486a1ec909 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

Chris Lattner adcfc1748b 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)

Chris Lattner a3159af703 Fix a bug where we would not promote calls to invokes if they occured in 
the same block as the setjmp.  Thanks to Greg Pettyjohn for noticing this!

Reid Spencer ce7ce1628f Eliminate calls to system dependent function getuid by using 
the newly implemented sys::Process::GetCurrentUserId function. Replace
similarly for getgid.

Chris Lattner f6302441f0 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. :)

Chris Lattner ab1ed77570 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.

Chris Lattner 374e659466 Instcombine this: 
%shortcirc_val = select bool %tmp.1, bool true, bool %tmp.4             ; <bool> [#uses=1]
        %tmp.6 = cast bool %shortcirc_val to int                ; <int> [#uses=1]

into this:

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

not this:

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

Chris Lattner b38b443b15 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.

Reid Spencer 8424ba373e For Bug 543: 
Standardize the error messages to be in "path: what failed: why" format.
Also attempt to use the correct errno to ThrowErrno in situations where
the errno value is erased by subsequent system calls.

Reid Spencer b02566dc1c For Bug 543:

parameter so that callers can specify the error number to be used.

Chris Lattner 8cb10a1775 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.
