[LLVMdev] Additional Optimization I'm Missing?
Hello, I'm working on using the LLVM JIT for a little project of mine,
amazing work first off! I have a question about optimization passes. I
initially have this function I've created, in python it looks like this:
OS_end = 50OS_start = 0OS_timestep = 1birth_rate = .3population =
30.0for time in range(OS_start, OS_end, OS_timestep):
births = birth_rate * population
deaths = 0.1

is this a bug in an optimization pass?
The frontend code is a pretty simple for loop, that counts from i = 0;
i != 10; i += 1
It gets optimized into and endless loop.
export fn entry() void {
var array: [10]Bar = undefined;
var x = for (array) |elem, i| {
if (i == 1) break elem;
} else bar2();
}
Here's the generated IR:
; ModuleID = 'test'
source_filename = "test"
target datalayout =

[LLVMdev] LICM/store-aliasing of global loads
Our frontend can guarantee that loads from globals are
rematerializable and do not alias with any stores in any function in
the given module. We'd like the optimization passes (and ideally the
register allocator as well) to be able to use this fact. The globals
are not constant "forever" but are constant during the calling of any
given function in the module.

[LLVMdev] [llvm-commits] r192750 - Enable MI Sched for x86.
I should mention a couple of useful self-explanatory LLVM flags for triage:
-enable-misched=false
-verify-misched
