-### XER CA bit (carry)
-
-Not sure the way I'm doing this is right. addic/subficx/etc set it to the value
-of the overflow bit from the LLVM *_with_overflow intrinsic.
-
-### Overflow
-
-Overflow bits can be set via the intrinsics:
-`llvm.sadd.with.overflow`/etc
-It'd be nice to avoid doing this unless absolutely required. The SDB could
-walk functions to see if they ever read or branch on the SO bit of things.
-
-### Conditions
-
-Condition bits are, after each function:
-```
-if (target_reg < 0) { CR0 = b100 | XER[SO] }
-if (target_reg > 0) { CR0 = b010 | XER[SO] }
-else                { CR0 = b001 | XER[SO] }
-```
-Most PPC instructions are optimized by the compiler to have Rc=0 and not set the
-bits if possible. There are some instructions, though, that always set them.
-For those, it would be nice to remove redundant sets. Maybe LLVM will do it
-automatically due to the local cr? May need to split that up into a few locals
-(one for each bit?) to ensure deduping.
-
-### Branch Hinting
-
-`@llvm.expect.i32`/`.i64` could be used with the BH bits in branches to
-indicate expected values.
-
-### Data Caching
-
-dcbt and dcbtst could use LLVM intrinsic @llvm.prefetch.
-
-## Codegen
-
-### Calling convention
-
-Experiment with fastcc? May need typedef fn ptrs to call into the JITted code.
-
-### Function calling convention analysis
-
-Track functions to see if they follow the standard calling convention.
-This could use the hints from the EH data in the XEX. Looking specifically for
-stack prolog/epilog and branches to LR.
-
-Benefits:
-- Optimized prolog/epilog generation.
-- Local variables for stack storage (alloca/etc) instead of user memory.
-- Better return detection and fast returns.
-
-### Indirect branches (ctr/lr)
-
-Return path:
-- In SDB see if the function follows the 'return' semantic:
-  - mfspr LR / mtspr LR/CTR / bcctr -- at end?
-- In codegen add a BB that is just return.
-- If a block 'returns', branch to the return BB.
-
-Tail calls:
-- If in a call BB check next BB.
-- If next is a return, optimize to a tail call.
-
-Fast path:
-- Every time LR would be stashed, add the value of LR (some NIA) to a lookup
-  table.
-- When doing an indirect branch first lookup the address in the table.
-- If not found, slow path, else jump.
-
-Slow path:
-- Call out and do an SDB lookup.
-- If found, return, add to lookup table, and jump.
-- If not found, need new function codegen!

-## Linking/multicore processing
-
-Need to split up processing of functions.
-ModuleGenerator::Generate's BuildFunction loop is the real time hog here.
-Spin up N threads. Each as a module and steals functions from the queue to
-generate. After the module hits a certain size it's dumped to disk and another
-is created.
-Afterwards, all modules are loaded lazily and linked together. The final one
-is writen out and loaded again lazily.
-JIT works on that.
