* m88k ELF toolchain, supporting static binaries only so far.miod2013-01-015-72/+502
| | | | | | | | | | | | | | | | | | Assembler supports a register prefix of `#' when configured for SVR4, and `%' when configured for OpenBSD. Pseudo-ops do not need a leading dot, except when configured for OpenBSD, allowing the `set' instruction to be recognized correctly. Based upon various unfinished or unreliable works, including smurph@'s early work in 2003, my own attempts in 2004 and 2005, and Michael Kato's binutils 2.15 diff from 2005. Support for register prefixes, as well as fixing an evil off-by-one in resolving 16-bit pc-relative relocations in ld (which would only affect kernel .S files branching to global symbols), came as part of the 2012 work. Not enabled yet (needs Makefile.bsd-wrapper, bfd/config.bfd and gdb/configure.tgt updates to completely enable) so as not to disturb the existing a.out toolchain builds; will hopefully be enabled very soon.

* Add a new option to the mips64 gas, -mfix-loongson2f-btb. This optionmiod2010-02-032-2/+86
| | | | | | | | | | | | | | | | | | | | | | is intended to be used when compiling kernel code which will run on a Loongson 2E or 2F processor, and inserts an explicit BTB clear operation before every jump through a register (jr or jalr instructions), unless that register is k0 or k1, or we are in .set noat. This is a reliable, although aggressive, workaround for the misbehaviour of the branch prediction engine of many Loongson 2F processors with regard to the Branch Translation Buffer, for which an official errata has yet to be published, and for which the Loongson suggested workaround apparently only works due to pipeline side effects, but requires all the executable kernel code to be located in CKSEG0/CKSEG1. These changes are inspired by a backport of the Loongson binutils 2.19 patch to binutils 2.18; the idea of doing an aggressive BTB clear is mine. This causes no functional change to code compiled without the -mfix-loongson2f-btb option. ``looks reasonable'' kettenis@

| | | | | | | | | | | | | | | | | | | | | - extra $(SHELL) and sugar for make (so that files not mode +x still work) - safer temp file handling - our W^X binary layout changes in ld - OpenBSD policy for library file selection in ld - arm and m88k changes which were not merged in time for official 2.15 - bfd core file handling - a couple typos New for 2.15: - ld(1) and as(1) manpages now generated at build time - binutils/stabs.c reverted to use our in-tree libiberty for now - we still use our VIA C3 crypto code over stock binutils, as it recognizes more instructions - new emulations for OpenBSD on mips64 machines, to help OpenBSD/sgi - relaxed %f# handling in gas on OpenBSD/sparc64 (same as was in 2.14) Tested on all platforms by various people; special thanks to sturm@ and otto@.

* A working gcc 2.95/m88k compiler, for some low standard value of working.miod2003-08-012-0/+2
| | | | | | | | | | | | Configuration settings mostly borrowed from the former gcc 2.8 configuration. A few typos and fixes backported from gcc 3.3, and a hell lot of fixes from my fingertips. This is enough to yield a compiler which will produce correct code at -O0. Optimization is slightly broken for some constructs, and more fixes are in the pipeline. ok deraadt@
