A Propeller link (similar to a Thin Link as used by ThinLTO)?
I met with the Propeller team today (we work for the same company but it
was my first time meeting two members on the team:) ).
One thing I have been reassured:
* There is no general disassembly work. General
disassembly work would assuredly frighten off developers. (Inherently
unreliable, memory usage heavy and difficult to deal with CFI, debug
information, etc)
Minimal amount of plumbing work

Optimization of successive constant stores
Hmm... found an interesting issue:
Given:
%2 = getelementptr inbounds %UodStructType* %0, i32 0, i32 0
store i8 1, i8* %2, align 8
%3 = getelementptr inbounds %UodStructType* %0, i32 0, i32 1
store i8 2, i8* %3, align 1
%4 = getelementptr inbounds %UodStructType* %0, i32 0, i32 2
store i8 3, i8* %4, align 2
%5 = getelementptr inbounds %UodStructType* %0, i32 0, i32 3

Aligned vector spills and variably sized stack frames
I've run into a problem that I'm trying to figure out how to address and
would welcome ideas and feedback.
Today, the vectorizer will nicely vectorize loops using the widest legal
vector type for the target. On a reasonable recent machine, this will
often end up using AVX2 registers which are 32 bytes wide.
If during register allocation, we decide to spill one of these
registers, we

Do I need to modify the AddrLoc of LLD for ARC target?
Hello Leslie,
I think we are going to need to know a bit more about the ELF ABI for
what looks like the ArcCompact before we can help you.
LLD's calculation of P (the place to be relocated) is as it is in the
generic ELF specification. The Rel.Offset corresponds to the ELF
r_offset field. This is covered by: "For a relocatable file, the value
is the byte offset from the beginning of the
