* Add aliases for __aeabi_idivmod and __aeabi_uidivmod calls clang emits.jsg2017-10-261-1/+3
| | | | | Remainder of the division is already stored in r1 in __divsi3/__udivsi3. ok kettenis@
* Add an implementation of __aeabi_ldivmode() and __aeabi_uldivmod(); clangkettenis2016-09-242-0/+183
| | | | | | | | | generates calls to these functions when compiling an armv7 kernel. Code from NetBSD's unified userland+kernel implementation, with lots of irrelevant (for us) #ifdefs removed. ok patrick@, guenther@
* Add aeabi aliases.kettenis2016-09-221-1/+4
| | | | ok guenther@, patrick@
* At some point arm moved to a unified syntax for arm and thumb instructions.jsg2015-06-082-39/+43
| | | | | | | | | While binutils supports both "unified" and "divided" syntax (defaulting to divided) the integrated assembler in clang only supports unified names so switch some files to unified syntax. Similiar changes were made in bitrig and freebsd. No difference in objdump -d output. tested on zaurus by deraadt@, ok miod@
* unifdef __APCS_26__ we don't run on anything with a 26 bit program counter.jsg2014-12-305-61/+5
| | | | | This codepath was removed in the NetBSD code this is derived from back in 2003 and was removed in Bitrig earlier this year. No binary change.
* Make bcopy() involve memmove(), not memcpy().miod2013-06-152-4/+3
| | | | Do not bogusly return NULL if dst == src (spotted by tedu@)
* remove ovbcopy supportderaadt2013-06-111-1/+0

* First pass at removing clauses 3 and 4 from NetBSD licenses.ray2008-06-265-40/+5
| | | | | | | | | 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@
* place a comment as to why these are otherwise emptyderaadt2007-11-281-0/+1

* libkern, begone. Move to a new mechanism where config(8)'s "file"deraadt2007-11-254-34/+6
| | | | | | | | | | | | directive can select between MI and MD versions of these files. 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..
