<div dir="ltr">Hi Tim, Hi Yoshiki,<div><br></div><div> we made some changes to register allocation in recent weeks and we've broken register saving from machine-code to run-time callouts on ARM. It shows up in the simulator and I'm looking at it now. I suspect VMMaker.oscog-eem.1756. Anyway, apologies, and I'm trying to fix it now. The symptom is that the first assert in the following fails when generating the run-time trampoline calls at start-up:</div><div><br></div><div><div>CogARMCompiler>>genSaveRegs: regMask</div><div><span class="" style="white-space:pre"> </span>"Save the registers in regMask for a call into the C run-time from a trampoline.</div><div><span class="" style="white-space:pre"> </span> Save none, because the ARM ABI only defines callee saved registers, no caller-saved regs.</div><div><span class="" style="white-space:pre"> </span> But for the future..."</div><div><span class="" style="white-space:pre"> </span>self assert: regMask = 0.</div><div><span class="" style="white-space:pre"> </span>self deny: (regMask anyMask: (cogit registerMaskFor: SP and: FPReg and: LR and: PC)).</div><div><span class="" style="white-space:pre"> </span>R12 to: R0 by: -1 do:</div><div><span class="" style="white-space:pre"> </span>[:reg|</div><div><span class="" style="white-space:pre"> </span> (regMask anyMask: (cogit registerMaskFor: reg)) ifTrue:</div><div><span class="" style="white-space:pre"> </span>[cogit PushR: reg]].</div><div><span class="" style="white-space:pre"> </span>^0</div></div><div><br></div><div><br></div><div>I should have it fixed quickly.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, May 9, 2016 at 11:53 AM, tim Rowledge <span dir="ltr"><<a href="mailto:tim@rowledge.org" target="_blank">tim@rowledge.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class=""><br>
