[LLVMdev] Dropping the DW_ prefix from names in dwarfdump
Hear hear. DW_ adds no readability but AT_/TAG_/OP_/etc do.
Dropping the FORM entirely is fine; I view that as a mechanical encoding thing, not relevant to the informational content. If you're debugging the encoding then it would matter, but for a random string-value attribute it really doesn't matter which of the 3 (4?) different forms was used as long as the actual string shows up

[LLVMdev] Dropping the DW_ prefix from names in dwarfdump
Hey guys,
Frederic is introducing the expression dumping support and in the interests
of tersity is skipping the "DW_" in every "DW_OP" (heck, we could even skip
the "OP" given the context - nothing else textual can appear there, right?)
Any thoughts on skipping the "DW_" (maybe even the AT/TAG/FORM too) in the
rest of dwarfdump? (skipping the AT/TAG (FORM

[LLVMdev] DW_AT_location not getting generated for local variables
I figured out my previous problem with DIBuilder. However, now I can't seem
to get the compiler to emit location information for local variables.
Here's how my IR looks:
---
define i32 @"\01_main"() {
init:
%exception1 = alloca i8*
%0 = alloca i32
%"bar:Int32" = alloca i32
%1 = alloca i32
%2 = alloca i32*
br label %code

[LLVMdev] llvm-dwarfdump improvements
Hi,
[ I think I put the most important contributors to the DebugInfo stuff in Cc:. Is there anyone else that I am missing? ]
Just a short notice that I am currently working on making llvm-dwarfdump more developer friendly. There are quite a few features in Darwin’s dwarfdump that we find quite useful and that we would like to contribute to llvm-dwarfdump.
I have started by augmenting the

[LLVMdev] DW_AT_location not getting generated for local variables
I found the problem. The llvm.dbg.declare call must have a !dbg tag,
otherwise the location info is not generated. Changing the invocation
in my original example to "call void @llvm.dbg.declare(metadata !{i32*
%"bar:Int32"}, metadata !13), !dbg !16" causes MC to generate the
local location as expected.

[LLVMdev] [Debug Info PATCH] for support of ref_addr and removal of DIE duplication
The first patch seems fine, though the comment on the modified addDIEEntry
function is a bit confusing:
-/// addDIEEntry - Add a DIE attribute data and value.
+/// addDIEEntry - Add a DIE attribute data and value. The form should be
+/// a reference form: ref1, ref2, ref4, ref8, ref_udata, ref_addr,
+/// or ref_sig8. A form can be chosen inside addDIEEntry.

DWARF: Should type units be referenced by signature or declaration?
Bunch of initially unrelated context:
* type units can be referenced in a variety of ways:
* DW_FORM_ref_sig8 on any attribute needing to reference the type
* DW_AT_signature on a declaration of the type
* extra wrinkle: the declaration can be nested into the appropriate
namespace and given a name, or not
* LLVM always does the "most expressive"/expensive thing: a full
