Chris Lattner 66e6a8229a This is the first major step of implementing PR1226. We now successfully 
scalarrepl things down to elements, but mem2reg can't promote elements that
are memset/memcpy'd.  Until then, the code is disabled "0 &&".

Chris Lattner 5fdded1d2f Add some simplifications for demanded bits, this allows instcombine to turn: 
define i64 @test(i64 %A, i32 %B) {
        %tmp12 = zext i32 %B to i64             ; <i64> [#uses=1]
        %tmp3 = shl i64 %tmp12, 32              ; <i64> [#uses=1]
        %tmp5 = add i64 %tmp3, %A               ; <i64> [#uses=1]
        %tmp6 = and i64 %tmp5, 123              ; <i64> [#uses=1]
        ret i64 %tmp6
}

into:

define i64 @test(i64 %A, i32 %B) {
        %tmp6 = and i64 %A, 123         ; <i64> [#uses=1]
        ret i64 %tmp6

This implements Transforms/InstCombine/add2.ll:test1

Chris Lattner e2e13caeb2 canonicalize constants to the RHS of addc/adde. If nothing uses the carry out of 
addc, turn it into add.

This allows us to compile:

long long test(long long A, unsigned B) {
  return (A + ((long long)B << 32)) & 123;
}

into:

_test:
        movl $123, %eax
        andl 4(%esp), %eax
        xorl %edx, %edx
        ret

instead of:

        movl %edx, %eax
        addl 4(%esp), %eax   ;; add of zero

Chris Lattner d7b4c92cd0 make better use of LCSSA information in RewriteLoopExitValues. Before, we 
would scan the entire loop body, then scan all users of instructions in the
loop, looking for users outside the loop.  Now, since we know that the
loop is in LCSSA form, we know that any users outside the loop will be LCSSA
phi nodes.  Just scan them.

This speeds up indvars significantly.

Reid Spencer e586f2e7f7 1. Handle errors around the ModuleProvider. This is necessary since it is 
reading bytecode.
2. The interpreter can delete the ModuleProvider and replace it with
   another so don't depend on it being around after the EE is created.
3. Don't just run llvm_shutdown on exit but actually delete the EE as well.
   This cleans up a vast amount of memory (but not all) that EE retained
   through exit.

 2007-03-03 05:29:51 +00:00
Chris Lattner da1d04a057 my recent change caused a failure in a bswap testcase, because it changed 
the order that instcombine processed instructions in the testcase.  The end
result is that instcombine finished with:

define i16 @test1(i16 %a) {
        %tmp = zext i16 %a to i32               ; <i32> [#uses=2]
        %tmp21 = lshr i32 %tmp, 8               ; <i32> [#uses=1]
        %tmp5 = shl i32 %tmp, 8         ; <i32> [#uses=1]
        %tmp.upgrd.32 = or i32 %tmp21, %tmp5            ; <i32> [#uses=1]
        %tmp.upgrd.3 = trunc i32 %tmp.upgrd.32 to i16           ; <i16> [#uses=1]
        ret i16 %tmp.upgrd.3
}

which can't get matched as a bswap.

This patch makes instcombine more sophisticated about removing truncating
casts, allowing it to turn this into:

define i16 @test2(i16 %a) {
        %tmp211 = lshr i16 %a, 8
        %tmp52 = shl i16 %a, 8
        %tmp.upgrd.323 = or i16 %tmp211, %tmp52
        ret i16 %tmp.upgrd.323
}

which then matches as bswap.  This fixes bswap.ll and implements
InstCombine/cast2.ll:test[12].  This also implements cast elimination of
add/sub.

        %reg1034 = tMOVri8 0
        tCMPi8 %reg1029<kill>, 0
        tBcc mbb<entry,0x8b06a10>, 0
    Successors according to CFG: 0x8b06980 0x8b06a10

entry (0x8b06980, LLVM BB @0x8b01b30, ID#12):

        %reg1036 = tMOVrr %reg1034<kill>
    Successors according to CFG: 0x8b06a10

        %reg1024<dead> = tMOVrr %reg1030<kill>
        ...

reg1030 and r1 have already been joined. When reg1024 and reg1030 are joined,
r1 live range from function entry to the tMOVrr instruction are dead. Eliminate
r1 from the livein set of the entry BB, not the BB where the copy is.

Chris Lattner b15e2b182f Fix a significant algorithm problem with the instcombine worklist. removing 
a value from the worklist required scanning the entire worklist to remove all
entries.  We now use a combination map+vector to prevent duplicates from
happening and prevent the scan.  This speeds up instcombine on a large file
from the llvm-gcc bootstrap from 189.7s to 4.84s in a debug build and from
5.04s to 1.37s in a release build.

this to a NOTE: because pari/gp results start to get rounded incorrectly
after 192 bits of precision. APInt and pari/gp never differ by more than
1, but APInt is more accurate because it does not lose precision after 192
bits as does pari/gp.
