[LLVMdev] LLVM GHC Backend: Tables Next To Code
Hmm writing a blog post about TNTC is beyond the time I have right now.
Here is some high level documentation of the layout of Heap objects in GHC:
http://hackage.haskell.org/trac/ghc/wiki/Commentary/Rts/Storage/HeapObjects#InfoTables
With TNTC enabled we generate code for closures of this form:
.text
.align 8
.long Main_main1_srt-(Main_main1_info)+0
.long 0
.quad 4294967299
.quad 0

It would be great to have this. However, the design will be tricky. Is there anything that spells out how the TNTC optimization works at the actual machine instruction level? It

[LLVMdev] LLVM GHC Backend: Tables Next To Code
Hello everyone,
On behalf of GHC hackers, I would like to discuss the possibility of
having a proper implementation of the tables-next-to-code optimisation
in LLVM.
Currently, the object code produced by all three GHC backends follows
the convention that the table with the metadata of a closure is
located immediately before the code of the closure. This makes it
possible to get to both the code
