...is program as an example: volatile int x; int __attribute__((noinline)) foo() { return x; } int main() { for (int i = 0; i < 10; ++i) { foo(); } } The resultant output code spills 'i' within the loop (I have to compile with -fno-unroll-loops else the loop and 'i' gets optimized away) while 'i' is assigned to a register that is used nowhere else in the generated program and I would consider 'foo' easy to analyse. At the call site of 'foo' the debugging output reports that the stack pointer and return value registers are "imp-use" and &q...

...run at an acceptable speed with a bit of tuning... did you tell it to write the least significant bits separately (set the parameter base_2_part=true)? Also altering the algorithm so that low_bits is larger will produce a speedup (but impact the compression ratio). And there's a fair scope for optimization. Overall, the speed (after encoding the least significant bits and dividing them out) is going to be of the order of the sum of the integers to be encoded.

I would like to host a phone meeting to discuss the plans for the xen sub-architecture of x86. Hopefully Chris can share his vision and we can agree on some next steps to getting this done and into the mainline kernel. From my understanding, it would be good if the "To" list could make it. If anyone believes others should attend, please let them know. Please let me know if you are
