similar to: [RFC] Potential extension to asm statement functionality

The team I am working with is using asm statements containing label definitions as a way of instrumentation so that when an application is loaded into their debug and test framework, the labels will cause breakpoints to be set at strategic points where they can query the state of the processor that the application is running on. ~ Todd From: Eli Friedman [mailto:efriedma at quicinc.com] Sent:

Hi Paul, Regarding the "No Touchie!" constraint idea for asm statements: would this be a new qualifier (like volatile) that could be applied to the asm statement? Since the constraint is not necessarily associated with an input or output operand, it seems that introducing the constraint via the qualifier field might work. All, The volatile qualifier on an asm statement already

In R devel rev.66393 (2014-08-15) it was possible to do this: trace(optim, exit = quote(str(returnValue()))) but returnValue() does not seem to be available any more. The above was useful to get the output of a function when it was called deep within another function that I have no control over. Has this been replaced by some other equivalent function? P.S. This demonstrates that it no

Hi All, My codegen is trying to generate some thing like this: entry: .... %34 = icmp ne i32 %33, 15 br i1 %34, label %then, label %else then: ; preds = %entry %returnValue = or i1 true, false .... br label %ifmerge else: ; preds = %entry br label %ifmerge ifmerge:

Drear there: The problem I have is to lower an intrinsic function like this ” float @llvm.write.arg(flaot %src, float* %dst) “ I am lowering it with INTRINSIC_W_CHAIN, so the return value and the value to write to dst are generated with some operations using src: " // it is the frame index node corresponding to input pointer SDvalue frindex = Op.getoperand(3); … SDValue returnValue =

Some formula methods for S3 generic functions use the idiom returnValue$call <- sys.call(sys.parent()) to show how to recreate the returned object or to use as a label on a plot. It is often followed by returnValue$call[[1]] <- quote(myName) E.g., I see it in packages "latticeExtra" and "leaps", and I suspect it used in "lattice" as well. This idiom

Hi Sarath, It would have really helped if you had removed the commented out code and inlined the calls to your homemade helper functions before sending it... You are doing this, in LLVM IR: %0 = getelementptr %Value* %firstArg, i32 0 ; i8** %1 = load i8** %0 ; i8* %2 = bitcast i8* %1 to i64* %3 = getelementptr %Value* %secondArg, i32 0 ; i8** %4 = load i8** %3; i8* %5 = bitcast i8* %4 to i64*

Yeah, that's the fault...got the answer...... Thanks James for the help... Struggling with this for so many days.......

I would like to add a target-dependent attribute to the LLVM IR, and the guidance in http://llvm.org/docs/HowToUseAttributes.html says that target-dependent attributes should not occupy a slot in the Attribute::AttrKind enum, but I have yet to find an attribute that is represented in the IR that does not also have a slot in the AttrKind enum. We are limited to 63 slots in the AttrKind enum

In llvm/lib/CodeGen/AsmPrinter/DwarfUnit.cpp, the compiler can emit a DW_AT_calling_convention attribute with a DW_TAG_class_type (and it looks like a DW_TAG_variant_part, DW_TAG_structure_type or DW_TAG_union_type as well), but the DWARF 4 specification says that DW_AT_calling_convention is not a valid attribute for any of those three DWARF tags. Downstream object consumers that check to verify

I have the same question as James has. It seems to me that you can name any address using an absolute symbol, and that should suffice to handle memory-mapped peripherals and such. If you really need to define data (whether it's in .data or .bss) or a function at a fixed memory address, that's not something you can do with absolute symbols (but you can do with linker scripts), but is this

Thank you guys, now I understand the problem. I am trying to avoid using stack memory (or mutable variable is the term used in the tutorial). I am also trying to optimize the code as much as I can before using optimizer passes such as mem2reg (to reduce the compile time as well).
