2006-02-01 23:01:57 +00:00
Chris Lattner aa23fa9f43 Implement smart printing of inline asm strings, handling variants and
substituted operands.  For this testcase:

int %test(int %A, int %B) {
  %C = call int asm "xyz $0, $1, $2", "=r,r,r"(int %A, int %B)
  ret int %C
}

we now emit:

_test:
        or r2, r3, r3
        or r3, r4, r4
        xyz r2, r2, r3  ;; look here
        or r3, r2, r2
        blr

... note the substituted operands. :)

Chris Lattner 1558fc64f9 Implement simple register assignment for inline asms. This allows us to compile:
int %test(int %A, int %B) {
  %C = call int asm "xyz $0, $1, $2", "=r,r,r"(int %A, int %B)
  ret int %C
}

into:

 (0x8906130, LLVM BB @0x8902220):
        %r2 = OR4 %r3, %r3
        %r3 = OR4 %r4, %r4
        INLINEASM <es:xyz $0, $1, $2>, %r2<def>, %r2, %r3
        %r3 = OR4 %r2, %r2
        BLR

which asmprints as:

_test:
        or r2, r3, r3
        or r3, r4, r4
        xyz $0, $1, $2      ;; need to print the operands now :)
        or r3, r2, r2

Evan Cheng 9e350cd6ad - Use xor to clear integer registers (set R, 0).
- Added a new format for instructions where the source register is implied
  and it is same as the destination register. Used for pseudo instructions
  that clear the destination register.

        %D = alloca int
        %A = call int asm "cpuid", "=eax,==ebx,==ecx,==edx,eax"(int* %B, int* %C, int* %D, int %op)

        add %EAX, %ECX
        mov %EBX, DWORD PTR [%ESP]

uint %test(uint %X) {
        %Y = call uint %llvm.ctpop.i32(uint %X)
        ret uint %Y
}

to:

test:

        sll %i0, 0, %l0
        popc %l0, %i0
        restore %g0, %g0, %g0
        retl
        nop

instead of to 40 logical ops.  Note the shift-by-zero that clears the top
part of the 64-bit V9 register.

2006-01-30 05:48:37 +00:00
Chris Lattner 99dcb95e14 First step towards V9 instructions in the V8 backend, two conditional move
patterns.  This allows emission of this code:

t1:
        save -96, %o6, %o6
        subcc %i0, %i1, %l0
        move %icc, %i0, %i2
        or %g0, %i2, %i0
        restore %g0, %g0, %g0
        retl
        nop

instead of this:

t1:
        save -96, %o6, %o6
        subcc %i0, %i1, %l0
        be .LBBt1_2     !
        nop
.LBBt1_1:       !
        or %g0, %i2, %i0
.LBBt1_2:       !
        restore %g0, %g0, %g0
        retl
        nop

for this:

int %t1(int %a, int %b, int %c) {
        %tmp.2 = seteq int %a, %b
        %tmp3 = select bool %tmp.2, int %a, int %c
        ret int %tmp3
}

Chris Lattner af209b8b13 When lowering SELECT_CC, see if the input is a lowered SETCC. If so, fold
the two operations together.  This allows us to compile this:

void %two(int %a, int* %b) {
        %tmp.2 = seteq int %a, 0
        %tmp.0.0 = select bool %tmp.2, int 10, int 20
        store int %tmp.0.0, int* %b
        ret void
}

into:

two:
        save -96, %o6, %o6
        or %g0, 20, %l0
        or %g0, 10, %l1
        subcc %i0, 0, %l2
        be .LBBtwo_2    ! entry
        nop
.LBBtwo_1:      ! entry
        or %g0, %l0, %l1
.LBBtwo_2:      ! entry
        st %l1, [%i1]
        restore %g0, %g0, %g0
        retl
        nop

instead of:

two:
        save -96, %o6, %o6
        sethi 0, %l0
        or %g0, 1, %l1
        or %g0, 20, %l2
        or %g0, 10, %l3
        subcc %i0, 0, %l4

Chris Lattner d02b05473c Use the new "UpdateNodeOperands" method to simplify LegalizeDAG and make it
faster.  This cuts about 120 lines of code out of the legalizer (mostly code
checking to see if operands have changed).

It also fixes an ugly performance issue, where the legalizer cloned the entire
graph after any change.  Now the "UpdateNodeOperands" method gives it a chance
to reuse nodes if the operands of a node change but not its opcode or valuetypes.

This speeds up instruction selection time on kimwitu++ by about 8.2% with a
release build.

   reducing the size of LegalizeOp.
2. Fix a bug where expand(bswap i64) was wrong when i64 is legal.
3. Changed LegalizeOp/PromoteOp so that the legalizer never needs to be
   iterative.  It now operates in a single pass over the nodes.
4. Simplify a LOT of code, with a net reduction of ~280 lines.

Reid Spencer b4f9a6f110 For PR411:
This patch is an incremental step towards supporting a flat symbol table.
It de-overloads the intrinsic functions by providing type-specific intrinsics
and arranging for automatically upgrading from the old overloaded name to
the new non-overloaded name. Specifically:
  llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64
  llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64
  llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64
  llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64
  llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64
New code should not use the overloaded intrinsic names. Warnings will be
emitted if they are used.

Chris Lattner 257492c0ab Fix a bug I noticed by inspection: if the first instruction in the inlined
function was not an alloca, we wouldn't check the entry block for any allocas,
leading to increased stack space in some cases.  In practice, allocas are almost
always at the top of the block, so this was never noticed.
