Fix a miscompilation of:
...
long long foo(long long X) {
return (long long)(signed char)(int)X;
}
Instead of:
_foo:
extsb r2, r4
srawi r3, r4, 31
mr r4, r2
blr
we now produce:
_foo:
extsb r4, r4
srawi r3, r4, 31
blr
This fixes a miscompilation in ConstantFolding.cpp.

add a new SimplifyDemandedVectorElts method, which works similarly to
...
SimplifyDemandedBits. The idea is that some operations can be simplified if
not all of the computed elements are needed. Some targets (like x86) have a
large number of intrinsics that operate on a single element, but pass other
elts through unmodified. If those other elements are not needed, the
intrinsics can be simplified to scalar operations, and insertelement ops can
be removed.
This turns (f.e.):
ushort %Convert_sse(float %f) {
%tmp = insertelement <4 x float> undef, float %f, uint 0 ; <<4 x float>> [#uses=1]
%tmp10 = insertelement <4 x float> %tmp, float 0.000000e+00, uint 1 ; <<4 x float>> [#uses=1]
%tmp11 = insertelement <4 x float> %tmp10, float 0.000000e+00, uint 2 ; <<4 x float>> [#uses=1]
%tmp12 = insertelement <4 x float> %tmp11, float 0.000000e+00, uint 3 ; <<4 x float>> [#uses=1]
%tmp28 = tail call <4 x float> %llvm.x86.sse.sub.ss( <4 x float> %tmp12, <4 x float> < float 1.000000e+00, float 0.000000e+00, float 0.000000e+00, float 0.000000e+00 > ) ; <<4 x float>> [#uses=1]
%tmp37 = tail call <4 x float> %llvm.x86.sse.mul.ss( <4 x float> %tmp28, <4 x float> < float 5.000000e-01, float 0.000000e+00, float 0.000000e+00, float 0.000000e+00 > ) ; <<4 x float>> [#uses=1]
%tmp48 = tail call <4 x float> %llvm.x86.sse.min.ss( <4 x float> %tmp37, <4 x float> < float 6.553500e+04, float 0.000000e+00, float 0.000000e+00, float 0.000000e+00 > ) ; <<4 x float>> [#uses=1]
%tmp59 = tail call <4 x float> %llvm.x86.sse.max.ss( <4 x float> %tmp48, <4 x float> zeroinitializer ) ; <<4 x float>> [#uses=1]
%tmp = tail call int %llvm.x86.sse.cvttss2si( <4 x float> %tmp59 ) ; <int> [#uses=1]
%tmp69 = cast int %tmp to ushort ; <ushort> [#uses=1]
ret ushort %tmp69
}
into:
ushort %Convert_sse(float %f) {
entry:
%tmp28 = sub float %f, 1.000000e+00 ; <float> [#uses=1]
%tmp37 = mul float %tmp28, 5.000000e-01 ; <float> [#uses=1]
%tmp375 = insertelement <4 x float> undef, float %tmp37, uint 0 ; <<4 x float>> [#uses=1]
%tmp48 = tail call <4 x float> %llvm.x86.sse.min.ss( <4 x float> %tmp375, <4 x float> < float 6.553500e+04, float undef, float undef, float undef > ) ; <<4 x float>> [#uses=1]
%tmp59 = tail call <4 x float> %llvm.x86.sse.max.ss( <4 x float> %tmp48, <4 x float> < float 0.000000e+00, float undef, float undef, float undef > ) ; <<4 x float>> [#uses=1]
%tmp = tail call int %llvm.x86.sse.cvttss2si( <4 x float> %tmp59 ) ; <int> [#uses=1]
%tmp69 = cast int %tmp to ushort ; <ushort> [#uses=1]
ret ushort %tmp69
}
which improves codegen from:
_Convert_sse:
movss LCPI1_0, %xmm0
movss 4(%esp), %xmm1
subss %xmm0, %xmm1
movss LCPI1_1, %xmm0
mulss %xmm0, %xmm1
movss LCPI1_2, %xmm0
minss %xmm0, %xmm1
xorps %xmm0, %xmm0
maxss %xmm0, %xmm1
cvttss2si %xmm1, %eax
andl $65535, %eax
ret
to:
_Convert_sse:

xorps %xmm1, %xmm1

Fix PR902:
...
Errors are generated with the YYERROR macro which can only be called from
a production (inside yyparse) because of the goto statement in the macro.
This lead to several situations where GEN_ERROR was not called but
GenerateError was used instead (because it doesn't use YYERROR). However,
in such situations, catching the error much later (e.g. at the end of
the production) is not sufficient because LLVM can assert on invalid data
before the end of the production is reached. The solution is to ensure that
the CHECK_FOR_ERROR macro (which invokes YYERROR if there's an error) is
used as soon as possible after a call to GenerateError has been made.

Be far more careful when splitting a loop header, either to form a preheader
...
or when splitting loops with a common header into multiple loops. In particular
the old code would always insert the preheader before the old loop header. This
is disasterous in cases where the loop hasn't been rotated. For example, it can
produce code like:
.. outside the loop...
jmp LBB1_2 #bb13.outer
LBB1_1: #bb1
movsd 8(%esp,%esi,8), %xmm1
mulsd (%edi), %xmm1
addsd %xmm0, %xmm1
addl $24, %edi
incl %esi
jmp LBB1_3 #bb13
LBB1_2: #bb13.outer
leal (%edx,%eax,8), %edi
pxor %xmm1, %xmm1
xorl %esi, %esi
LBB1_3: #bb13
movapd %xmm1, %xmm0
cmpl $4, %esi
jl LBB1_1 #bb1
Note that the loop body is actually LBB1_1 + LBB1_3, which means that the
loop now contains an uncond branch WITHIN it to jump around the inserted
loop header (LBB1_2). Doh.
This patch changes the preheader insertion code to insert it in the right
spot, producing this code:
... outside the loop, fall into the header ...
LBB1_1: #bb13.outer
leal (%edx,%eax,8), %esi
pxor %xmm0, %xmm0
xorl %edi, %edi
jmp LBB1_3 #bb13
LBB1_2: #bb1
movsd 8(%esp,%edi,8), %xmm0
mulsd (%esi), %xmm0
addsd %xmm1, %xmm0
addl $24, %esi
incl %edi
LBB1_3: #bb13
movapd %xmm0, %xmm1
cmpl $4, %edi
jl LBB1_2 #bb1
Totally crazy, no branch in the loop! :)

Two things:
...
1. teach SimplifySetCC that '(srl (ctlz x), 5) == 0' is really x != 0.
2. Teach visitSELECT_CC to use SimplifySetCC instead of calling it and
ignoring the result. This allows us to compile:
bool %test(ulong %x) {
%tmp = setlt ulong %x, 4294967296
ret bool %tmp
}
to:
_test:
cntlzw r2, r3
cmplwi cr0, r3, 1
srwi r2, r2, 5
li r3, 0
beq cr0, LBB1_2 ;
LBB1_1: ;
mr r3, r2
LBB1_2: ;
blr
instead of:
_test:
addi r2, r3, -1
cntlzw r2, r2
cntlzw r3, r3
srwi r2, r2, 5
cmplwi cr0, r2, 0
srwi r2, r3, 5
li r3, 0
bne cr0, LBB1_2 ;
LBB1_1: ;
mr r3, r2
LBB1_2: ;
blr
This isn't wonderful, but it's an improvement.

Legalize is no longer limited to cleverness with just constant shift amounts.

Allow it to be clever when possible and fall back to the gross code when needed.
This allows us to compile:

return X << (C&~32);
}

long long foo2(long long X, int C) {

Fold the PPCISD shifts when presented with 0 inputs. This occurs for code
...
like:
long long test(long long X, int Y) {
return 1ULL << Y;
}
long long test2(long long X, int Y) {
return -1LL << Y;
}
which we used to compile to:
_test:
li r2, 1
subfic r3, r5, 32
li r4, 0
addi r6, r5, -32
srw r3, r2, r3
slw r4, r4, r5
slw r6, r2, r6
or r3, r4, r3
slw r4, r2, r5
or r3, r3, r6

_test2:

srw r3, r2, r3
slw r4, r2, r5
slw r2, r2, r6
or r3, r4, r3

If LSR went through a lot of trouble to put constants (e.g. the addr of a global
...
in a specific BB, don't undo this!). This allows us to compile
CodeGen/X86/loop-hoist.ll into:
_foo:
xorl %eax, %eax
*** movl L_Arr$non_lazy_ptr, %ecx
movl 4(%esp), %edx
LBB1_1: #cond_true
movl %eax, (%ecx,%eax,4)
incl %eax
cmpl %edx, %eax
jne LBB1_1 #cond_true
LBB1_2: #return
ret
instead of:
_foo:
xorl %eax, %eax
movl 4(%esp), %ecx
LBB1_1: #cond_true
*** movl L_Arr$non_lazy_ptr, %edx
movl %eax, (%edx,%eax,4)
incl %eax
cmpl %ecx, %eax
jne LBB1_1 #cond_true
