You can try running with -verify-machineinstrs to detect

Hi, attached is a second try for the bigstack patch for SPU, with testcase. It is essentially the patch committed as 97091, and reverted as 97099, but with the following additions: -in vararg handling, registers are marked to be live, to not confuse the register scavenger -function prologue and epilogue are not emitted, if the stack size is 16. 16 means it is empty - there is only the

...culateFrameObjectOffsets(Fn); ... if (target needs spill slot) { call setScavengingFrameIndex and reserve spill slot calculateFrameObjectOffsets(Fn); // redo calculation. } This seems to be simpler and more efficient since you don't need to write or run a function like ARM's estimateStackSize to estimate the stack size. Does this sound reasonable or is there something I am missing? -------------- next part -------------- An HTML attachment was scrubbed...
