11, 68 & 69) writable to allow easier profiling. Allow parameters expecting a float (statTenures, Sista CogCodeThreshold & statAverageLivePagesWhenMapping: 17, 55, 68) to take an int. Slang: Fix a bug in inferTypesForImplicitlyTypedVariablesIn:. We cannot derive types from variables assigned to until all assignments are typed. So exclude variables assigned from as-yet-untyped methods. The old code would simply ignore the types from as-yet-untyped methods, hence leaving the variable with a chosen-at-random, unmerged type. This fixes a number of cases. But there's still the weirdness that the return type of mapEndFor: in cogitX64SysV.c is correct (usqInt) but incorrect (sqInt) in cogitX64WIN64.c. Luckily this is benign, but still should be fixed asap.

Hi Kevin, > On Jun 22, 2017, at 6:12 AM, Kevin Driedger <notifications(a)github.com> wrote: > > Do you, @eliotmiranda , generate most of this code using VMMaker? Seems like the same change many times. > Yes (& not just me). The compilable source of the vm is made up of three components: - the platform source, maintained by hand, written mostly in C, with some Objective-C and C++, provides the platform-specific support to allow the vm to run on real machines. - the interpreter and JIT provide the execution engine, core language primitives and memory manager to execute Smalltalk (& Newspeak) - the plugins (src/plugins) provide a wide variety of extensions to the vm (from FFI to OpenGL to (de)compresssion The plugins, at least their surface primitives, and sometimes their algorithmic innards too, are written in Smalltalk The vm itself is entirely written (& developed) in Smalltalk (actually a subset of Smalltalk called Slang). These last two sets of sources are therefore translated automatically from Smalltalk/Slang to C. Whenever someone makes a change to the VMMaker.oscog package that necessitates new sources because by generated that person generates source and commits to opensmalltalk/vm. Since there are a variety of VMs: (smalltalk vs newspeak) * (interpreter vs cointerpreter+jit) * (32 vs 64 bits) * (V3 vs Spur object representations) * (standard vs Sista vs Lowcode instruction sets) a number of similar files are generated.

I broke the criterion for running global GC when I added the allocation measurement support. The GC is run when the heap is found to have grown by some ration (default 1.5) after each scavenge. When I added the allocation counting support I noticed that there was a bug in the determination of the size of the heap (the old code just looked at the extent of the heap, not the sum of the size of segments) and so I changed it to use the correct size. Evidently I've broken something. I'll fix it asap, but first have some other issues to attend to.
