load with alignment of 1 crashes from being unaligned
Below is attached a full IR module that can reproduce this issue, but the
part to notice is this:
%Foo96Bits = type <{ i24, i24, i24, i24 }>
define internal fastcc i16 @main.0.1() unnamed_addr #2 !dbg !113 {
Entry:
%value = alloca %Foo96Bits, align 1
%b = alloca i24, align 4
%0 = bitcast %Foo96Bits* %value to i8*, !dbg !129
call void @llvm.memcpy.p0i8.p0i8.i64(i8* %0, i8* bitcast

What does "preds" mean in a .ll file?
Hi,
I see things like this. What does it mean? Is it documented somewhere? Thanks.

Find uses of Metadata / DITypes
I'm looking for a way to efficiently traverse the Metadata structure in
reverse, or otherwise find DITypes that refer to another DIType. As an
example, say I have a DICompositeType describing a struct. Now I want to
find other DITypes containing this type, e.g. a DIDerivedType describing
its pointer type, or another struct containing this struct as one of its
fields. Is this possible in LLVM

Can you please open a bug on bugzilla and attach the ir testcase? Your fix
doesn't look right (just hiding the assertion failure)

[LLVMdev] [patch] Prototype/proof-of-concept for DWARF type units
This isn't a realistic/viable implementation, just a hacked up "can I make
it produce the right output" kind of thing, but while I hammer out a few
more details (like fixing MC to allow multiple sections with the same name
but different comdat groups) I figured I'd throw it out there to have a bit
of a chat about it.
I've tested simple cases of a single type and they seem to

assertion triggered since update to llvm 5
So, 90% of the time I've seen this, it was memory corruption, usually use
after free. I know I fixed one after 5.0 branched.
You should compile with address sanitizer enabled, and I suspect you will
find the issue quicky.
If not, we really need ir that reproduces it.

[LLVMdev] Next round of DWARF issues/questions
After to speaking to Devang and a number of other people at the developer's
conference, I was able to make some forward progress on getting debugging to
work. I'm now able to actually single-step through my program and set
breakpoints, and examine function parameters.
However, I'm also seeing a lot of new problems which weren't exposed before.
