* Replace a few more 32-bit instructions with the proper 64-bit equivalent.kettenis2011-11-271-22/+21
| | | | | Also fix the return value of memcpy. With these changes, this seems to work as advertised now.

* In the original sparc V7 book (and in the v8 book), the divrem leaf code usedderaadt2011-03-121-2/+2
| | | | | | | | | | | | | | | | | | | | | | | local registers for a few temporaries. This was changed to use two global registers. Maybe to permit use in-kernel without conflicting with the register V7 register window handlers. (Was this done by Chris Torek? Is this related to Gordon Irlam's work? Or was it in NetBSD? Hard to tell because NetBSD removed their original cvs tree.) In V8 the ABI was tightened; more global registers became offlimits in different ways. We started supporting sun4m, and did not consider this. As a result, the global registers chosen are the wrong choice. In particular, %g7 is a poor choice for upcoming TLS work. It looks like it is safer to use %g5 and %g6 since these functions are "system software". All re-entrant parts of the system save it. On sparc64 these functions are in libc per ABI requirement, but are unused. On sparc, they occur in bootblocks (no reentrancy), kernel (reentrancy saves globals; kernel is not ABI compliant), userland libc (signal handlers save globals), and ld.so (symbol binding is not re-entrant on its own). Discussed rather extensively with guenther, kettenis, miod and drahn.

* <machine/macros.h> would provide inline version of a few of the functionsmiod2009-08-198-5/+459
| | | | | | | | | | | | traditionnaly found in libkern. However, the memcmp() flavour would behave as bcmp() with only two possible return values: zero and positive non-zero. This broke the name cache RB trees which now rely upon proper memcmp() semantics(negative value, zero, or positive value). Just give up on these macros and provide the same code as libc, in libkern. As a side effect, this no longer uses the cmpc3 instruction, which is not implemented and requires (slow) kernel emulation, on the original uVax.

* unbreak ieeefp emulation code wrt converting double to unsignedmartynas2008-10-072-2/+90
| | | | | | | | | | | | | | | | long ints for alpha. we've got only one instruction (cvttq) to convert double-t to quadword, and float64_to_int64 did not take into account the unsigned conversions therefore, overflow always occured, and half of the unsigned range (LONG_MAX .. ULONG_MAX) was broken introduce roundAndPackInt64NoOverflow and float64_to_int64_no_overflow for softfloat, that works with unsigned integers as well. note that this will return zero for nan/inf/oflow/uflow, raising exception flag perl is happy now looked over by miod@ tested by naddy@, and by me on nick@'s alpha
* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-2611-85/+8
| | | | | | | | | Not sure what's more surprising: how long it took for NetBSD to catch up to the rest of the BSDs (including UCB), or the amount of code that NetBSD has claimed for itself without attributing to the actual authors. OK deraadt@

At the same time, adjust the boot programs to pick exactly what they need, instead of the 7 or 8 mechanisms previously used. There will be some fallout from this, but testing it all by myself is a ridiculously slow process; it will be finished in-tree. Various developers were very nice and avoided making fun of me when I was gibbering in the corner..
