Hi all, Please review this patch. It's fixing PR3232 comment #8. Function bar from 2008-03-24-BitFiled-And-Alloca.c compiles to: %struct.Key = type { { i32, i32 } } ... define i32 @bar(i64 %key_token2) nounwind { entry: %key_token2_addr = alloca i64 ; <i64*> [#uses=2] %retval = alloca i32 ; <i32*> [#uses=2] %iospec =

Hi all, The patch below is to fix a problem with unaligned memcpys. This program: void Bork() { int Qux[33] = {0}; } will currently produce this LLVM code on PPC64: @C.0.937 = internal constant [33 x i8] zeroinitializer define void @Bork() { entry: %Qux = alloca [33 x i8] %Qux1 = bitcast [33 x i8]* %Qux to i8* call void @llvm.memcpy.i64( i8* %Qux1, i8* getelementptr ([33 x i8]*

Dear Sir There are two packages of regional frequency analysis RFA and nsRFA. Are both give us same results if not then what you will suggest. I am confused about this.

Dear Sir in the following example,is the vector lmom a l-moment ratios vector? What is meant by size = northCascades[,1]? And what are the values in c(0.0104,0.0399,0.0405)? Please help me I am unable to understand these from help manual. Best Regards AMINA data(northCascades) lmom <- c(1, 0.1103, 0.0279, 0.1366) kappaParam <- kappalmom(lmom) heterogeneity(500, 19, size =

Add "cmask" table of constant register masks: if a bit is not writeable and is set in cmask table, this bit is checked on load. An attempt to load an image that would change such a register causes load to fail. Use this table to make sure that load does not modify registers that guest can not change (directly or indirectly). Note: we can't just assume that read-only registers never

This is 32 bit machine. 64 bit will definitely won't work due to bunch of stuff unimplemented: dwarf builtins, stack layout description, etc. -- With best regards, Anton Korobeynikov.

Hi Bill, is this a 64 bit machine? If so, did you make any adjustments based on http://lists.cs.uiuc.edu/pipermail/llvmdev/2007-August/010489.html ? Thanks, Duncan.

I'm getting a crash with some Objective-C code that involves "blocks". Basically, it gets to this "walk_all_functions" call and fails: lower_nested_functions (tree fndecl, bool skip_outermost_fndecl) { ... #ifdef ENABLE_LLVM walk_all_functions (construct_reverse_callgraph, root); propagate_chains (root); #endif ... } The construct_reverse_callgraph calls

Ciao, Duncan.

I did mark it as TREE_CONSTANT. Is that enough? -bw On Jan 5, 2009, at 2:03 AM, Duncan Sands <baldrick at free.fr> wrote: > Hi Chris, > >> I think this change is fine and should go into the normal apple GCC >> as >> well.

No idea - if it works I guess it was enough :) I was actually thinking of TREE_STATIC: /* In a VAR_DECL, nonzero means allocate static storage. In a FUNCTION_DECL, nonzero if function has been defined. In a CONSTRUCTOR, nonzero means allocate static storage. ??? This is also

Is the flag_objc_abi variable available on non-Darwin platforms in llvm-gcc? I want to use it in llvm-backend.cpp to conditionalize a test. But I don't want to break Linux, Ada, Fortran, etc. -bw

The Constants.cpp file returns a ConstantAggregateZero object when you pass it a c"\000" string. Here is the code: Constant *ConstantArray::get(const ArrayType *Ty, const std::vector<Constant*> &V) { // If this is an all-zero array, return a ConstantAggregateZero object if (!V.empty()) { Constant *C = V[0]; if (!C->isNullValue())
