[LLVMdev] Register Allocation: Interference graph
...VMTargetMachine.cpp. Does your
pass actually do register allocation, or will it? If so, you want
to use the RegisterRegAlloc object. Here is how linear scan uses it:
static RegisterRegAlloc
linearscanRegAlloc("linearscan", "linear scan register allocator",
createLinearScanRegisterAllocator);
Then createRegisterAllocator in CodeGen/Passes.cpp will pick up
your allocator and list it as an option under -regalloc=<allocator>.
If you pass is just doing some analysis and dumps you can either
add a invocation of it to LLVMTargetMachine.cpp or make some
other pass dependent on it...

[LLVMdev] Fast register allocation
...EmitPasses() {
// Set register scheduler & allocation policy.
RegisterScheduler::setDefault(createDefaultScheduler);
- RegisterRegAlloc::setDefault(Fast ? createLocalRegisterAllocator :

// Create the code generator passes.
I have tested clang self hosting on x86-64 and x64 with this patch.
On the nightly test suite, -regalloc=fast performs as well as -regalloc=local. See PR7154.
I expect we may see some problems with the register scavenger on ARM because -regalloc=fas...

[LLVMdev] FP emulation (continued)
Hi,
I still have some questions about FP emulation for my embedded target.
To recap a bit:
My target only has integer registers and no hardware support for FP. FP
is supported only via emulation. Only f64 is supported. All FP
operations should be implemented to use i32 registers.
Based on the fruitful discussions on this list I was already able to
implement mapping of the FP operations to
