Complete the integration of tbemd branch into head. TARGET_BIG_ENDIAN is now completely dead, except where it was originally supposed to be used (internally in the toolchain building). TARGET_ARCH has changed in three cases: (1) Little endian mips has changed to mipsel. (2) Big endian mips has changed to mipseb. (3) Big endian arm has changed to armeb. Some additional changes are needed to make 'make universe' work on arm and mips after this change, so those are commented out for now. UPDATING information will be forthcoming. Any remaining rough edges will be hammered out in -current. 2010-11-10 06:39:49 +00:00			`${MACHINE_ARCH} == "arm" \|\| \`
Merging of projects/armv6, part 3 r238211: Support TARGET_ARCH=armv6 and TARGET_ARCH=armv6eb This adds a new TARGET_ARCH for building on ARM processors that support the ARMv6K multiprocessor extensions. In particular, these processors have better support for TLS and mutex operations. This mostly touches a lot of Makefiles to extend existing patterns for inferring CPUARCH from ARCH. It also configures: * GCC to default to arm1176jz-s * GCC to predefine __FreeBSD_ARCH_armv6__ * gas to default to ARM_ARCH_V6K * uname -p to return 'armv6' * make so that MACHINE_ARCH defaults to 'armv6' It also changes a number of headers to use the compiler __ARM_ARCH_XXX__ macros to configure processor-specific support routines.

Retire TARGET_ABI. Implement MACHINE_ARCH=mips64e[lb] to build N64 images. This replaces MACHINE_ARCH=mipse[lb] TARGET_ABI=n64. MACHINE_ARCH=mipsn32e[lb] has been added, but currently requires WITHOUT_CDDL due to atomic issues in libzfs. I've not investigated this much, but implemented this to preserve as much of the TARGET_ABI functionality that I could. Since its presence doesn't affect the working cases, I've kept it in for now. Added mips64e[lb] to make universe, so more kernels build. And I think this (finally) closes the curtain on the tbemd tree. 2011-01-07 20:26:33 +00:00			`${MACHINE_ARCH:Mmips*el} != ""`

Assume a big-endian default on MIPS and drop the "eb" suffix from MACHINE_ARCH. This makes our naming scheme more closely match other systems and the expectations of much third-party software. MIPS builds which are little-endian should require and exhibit no changes. Big-endian TARGET_ARCHes must be changed: From: To: mipseb mips mipsn32eb mipsn32 mips64eb mips64 An entry has been added to UPDATING and some foot-shooting protection (complete with warnings which should become errors in the near future) to the top-level base system Makefile. 2012-03-29 02:54:35 +00:00			`${MACHINE_ARCH:Mmips*} != ""`
