[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

DICompileUnit duplication in LLVM 4.0.0?
...eUnits in a pass that worked in 3.8. I
assume I'm doing something wrong. Would someone be willing to point me in
the right direction?

[LLVMdev] question about -coverage
...like GEP around @__llvm_gcov_ctr have special metadata attached:
%2 = getelementptr inbounds [4 x i64]* @__llvm_gcov_ctr, i64 0, i64 %1
%3 = load i64* %2, align 8
%4 = add i64 %3, 1

...
!1 = metadata !{...; [ DW_TAG_compile_unit ] ... /home/kcc/tmp/cond.cc]
[DW_LANG_C_plus_plus]
Can we rely on having this metadata attached to @__llvm_gcov_ctr?
Should we attach some metadata to the actual accesses as well, or simply
find the corresponding GEP?
Finally, does anyone have performance numbers for coverage?
As of today it seems completely thread-hostile since __llvm_gcov_ctr...

Source locations missing when using xray-account
Hi David,
Sorry for taking a few days to reply. It's not easy for you to compile
a Haskell file to see the problem as the debug information is still
WIP. Below I prove the IR for a simple hello world program which you
can feed into llc.
https://gist.github.com/05296933e37e87533a51d493b46aa48d
The `out.ir` file can be passed straight to `llc`.
Can you see anything obviously wrong?
