Same patch as the previous on the store side. Before we compiled this:
struct DeclGroup {
unsigned NumDecls;
};
int foo(DeclGroup D) {
return D.NumDecls;
}
to:
%struct.DeclGroup = type { i32 }
define i32 @_Z3foo9DeclGroup(i64) nounwind ssp noredzone {
entry:
%D = alloca %struct.DeclGroup, align 4 ; <%struct.DeclGroup*> [#uses=2]
%tmp = alloca i64 ; <i64*> [#uses=2]
store i64 %0, i64* %tmp
%1 = bitcast i64* %tmp to %struct.DeclGroup* ; <%struct.DeclGroup*> [#uses=1]
%2 = load %struct.DeclGroup* %1, align 1 ; <%struct.DeclGroup> [#uses=1]
store %struct.DeclGroup %2, %struct.DeclGroup* %D
%tmp1 = getelementptr inbounds %struct.DeclGroup* %D, i32 0, i32 0 ; <i32*> [#uses=1]
%tmp2 = load i32* %tmp1 ; <i32> [#uses=1]
ret i32 %tmp2
}
which caused fast isel bailouts due to the FCA load/store of %2. Now
we generate this just blissful code:
%struct.DeclGroup = type { i32 }
define i32 @_Z3foo9DeclGroup(i64) nounwind ssp noredzone {
entry:
%D = alloca %struct.DeclGroup, align 4 ; <%struct.DeclGroup*> [#uses=2]
%tmp = alloca i64 ; <i64*> [#uses=2]
%coerce.dive = getelementptr %struct.DeclGroup* %D, i32 0, i32 0 ; <i32*> [#uses=1]
store i64 %0, i64* %tmp
%1 = bitcast i64* %tmp to i32* ; <i32*> [#uses=1]
%2 = load i32* %1, align 1 ; <i32> [#uses=1]
store i32 %2, i32* %coerce.dive
%tmp1 = getelementptr inbounds %struct.DeclGroup* %D, i32 0, i32 0 ; <i32*> [#uses=1]
%tmp2 = load i32* %tmp1 ; <i32> [#uses=1]
ret i32 %tmp2
}
This avoids fastisel bailing out and is groundwork for future patch.
This reduces bailouts on CGStmt.ll to 911 from 935.

improve CreateCoercedLoad a bit to generate slightly less awful
IR when handling X86-64 by-value struct stuff. For example, we
use to compile this:
struct DeclGroup {
unsigned NumDecls;
};
int foo(DeclGroup D);
void bar(DeclGroup *D) {
foo(*D);
}
into:
define void @_Z3barP9DeclGroup(%struct.DeclGroup* %D) ssp nounwind {

%D.addr = alloca %struct.DeclGroup*, align 8 ; <%struct.DeclGroup**> [#uses=2]

%tmp2 = bitcast %struct.DeclGroup* %tmp to i8* ; <i8*> [#uses=1]
call void @llvm.memcpy.p0i8.p0i8.i64(i8* %tmp1, i8* %tmp2, i64 4, i32 4, i1 false)
%0 = bitcast i64* %tmp3 to %struct.DeclGroup* ; <%struct.DeclGroup*> [#uses=1]

%2 = load i64* %tmp3 ; <i64> [#uses=1]
call void @_Z3foo9DeclGroup(i64 %2)
ret void
}
which would cause fastisel to bail out due to the first class aggregate load %1. With
this patch we now compile it into the (still awful):
define void @_Z3barP9DeclGroup(%struct.DeclGroup* %D) nounwind ssp noredzone {
entry:
%D.addr = alloca %struct.DeclGroup*, align 8 ; <%struct.DeclGroup**> [#uses=2]

%tmp1 = bitcast %struct.DeclGroup* %agg.tmp to i8* ; <i8*> [#uses=1]

call void @llvm.memcpy.p0i8.p0i8.i64(i8* %tmp1, i8* %tmp2, i64 4, i32 4, i1 false)

store i32 %1, i32* %0, align 1
%2 = load i64* %tmp3 ; <i64> [#uses=1]
%call = call i32 @_Z3foo9DeclGroup(i64 %2) noredzone ; <i32> [#uses=0]
ret void
}
which doesn't bail out. On CGStmt.ll, this reduces fastisel bail outs from 958 to 935,
and is the precursor of better things to come.

Change IR generation for return (in the simple case) to avoid doing silly
load/store nonsense in the epilog. For example, for:
int foo(int X) {
int A[100];
return A[X];
}
we used to generate:
%arrayidx = getelementptr inbounds [100 x i32]* %A, i32 0, i64 %idxprom ; <i32*> [#uses=1]
%tmp1 = load i32* %arrayidx ; <i32> [#uses=1]
store i32 %tmp1, i32* %retval
%0 = load i32* %retval ; <i32> [#uses=1]
ret i32 %0
}
which codegen'd to this code:
_foo: ## @foo
## BB#0: ## %entry
subq $408, %rsp ## imm = 0x198
movl %edi, 400(%rsp)
movl 400(%rsp), %edi
movslq %edi, %rax
movl (%rsp,%rax,4), %edi
movl %edi, 404(%rsp)
movl 404(%rsp), %eax
addq $408, %rsp ## imm = 0x198
ret
Now we generate:
%arrayidx = getelementptr inbounds [100 x i32]* %A, i32 0, i64 %idxprom ; <i32*> [#uses=1]
%tmp1 = load i32* %arrayidx ; <i32> [#uses=1]
ret i32 %tmp1
}
and:
_foo: ## @foo
## BB#0: ## %entry
subq $408, %rsp ## imm = 0x198
movl %edi, 404(%rsp)
movl 404(%rsp), %edi
movslq %edi, %rax
movl (%rsp,%rax,4), %eax
addq $408, %rsp ## imm = 0x198
ret
This actually does matter, cutting out 2000 lines of IR from CGStmt.ll
for example.
Another interesting effect is that altivec.h functions which are dead
now get dce'd by the inliner. Hence all the changes to
builtins-ppc-altivec.c to ensure the calls aren't dead.

Add "checker caching" to GRExprEngine::CheckerVisit to progressively build

As the number of checkers grows, this may potentially significantly reduce

for the ~20 registered Checker objects, only ~5 of them respond at any one time
to a give statement. While this isn't a net performance win right now (there

Implement dependent alignment attribute support. This is a bit gross given the
current attribute system, but it is enough to handle class templates which
specify parts of their alignment in terms of their template parameters.
This also replaces the attributes test in SemaTemplate with one that actually
tests working attributes instead of broken ones. I plan to add more tests here
for non-dependent attributes in a subsequent patch.

Fix PR7180.
For
void f( a::b::c );
we would cache the tokens "a::b::" but then we would try to annotate them using the range "a::".
Before annotating them with the (invalid) C++ scope spec, set it to the range of "a::b::".

-Introduce PCHWriter::AddTemplateArgumentLocInfo()
-Modify PCHWriter::AddTemplateArgumentLoc() to also write TemplateArgumentLoc's TemplateArgument
and move the existing calls of AddTemplateArgumentLoc() to AddTemplateArgumentLocInfo().

Make it easier to read/write the template part of FunctionDecl.
Introduce:
-FunctionDecl::getTemplatedKind() which returns an enum signifying what kind of templated
FunctionDecl it is.
-An overload of FunctionDecl::setFunctionTemplateSpecialization() which accepts arrays of
TemplateArguments and TemplateArgumentLocs
-A constructor to TemplateArgumentList which accepts an array of TemplateArguments.
