theraven	4be9799259	Unrolled the SparseArrayLookup loop. This means we only need one jump, instead of 2, which gives the same performance as the old GNU code and about half the memory usage. It's really, really, ugly code though - I need to teach the compiler to do this optimisation so I don't have to.	16 years ago
theraven	0d78186238	Some bug fixes and tidies. I now have an out-of-tree replacement for the dtable stuff, so sarray.{h,c} will be going away soon. The replacement offers similar (slightly worse currently) performance in microbenchmarks, but uses half as much memory (Gorm goes from 95MB to 48MB on my machine). This will be committed once it's been tweaked a little bit.	16 years ago
theraven	2d84b96a72	Tidied up some bits by creating private headers for private data structures. Imported selector table code frm the Étoilé runtime. We can now make dispatch type dependent with a -D switch. Not enabled yet, but it will be enabled in a warning mode soon - I consider preferable to the existing GNU and Apple solution of corrupting the stack.	16 years ago
