1968	6581 d 19 h	jermar	/tags/	Canonize pre-0.2.0.3 tags: remove inner branches, tags and trunk directories. The change now should reflect how those releases looked like after checkout.
1962	6581 d 20 h	jermar	/tags/0.1.0/	Tagging release 0.1.0
332	6993 d 4 h	palkovsky	/SPARTAN/trunk/	Updated symtab so that it works correctly with BE architectures. Changed compiler for BE MIPS to be mips-sgi-irix5, because mipsel -EB does not behave correctly. Doc updates to amd64. Added ARC BIOS support to MIPS architecture. Putchar works correctly, kernel passed FPU & some rwlock tests.
326	6994 d 16 h	palkovsky	/SPARTAN/trunk/	Cleanup of makefiles to have common options in one main makefile. Add simple build process for different simulators for MIPS. Added FPU context & lazy FPU context switching to MIPS. Cleanup of MIPS linker script. Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help. There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.
309	6998 d 7 h	palkovsky	/SPARTAN/trunk/	Added architecture independent hooks for fpu lazy context switching. It is enabled by defining FPU_LAZY
296	6999 d 6 h	palkovsky	/SPARTAN/trunk/	More logical fpu_context_engaged setting. The sse1 test now correctly tests for thread migration settings.
282	7000 d 9 h	palkovsky	/SPARTAN/trunk/	Fixed gdtr naming issues after ia32 changes. Fixed stack alignment on new thread to by multiple of 16, we are now ABI-correct and we do not #GP on va_arg to boot. Fixed bad exception register names reporting. Fixed bad _hardcoded_load_addr, which caused allocation of kernel text frames.
