332 6885 d 11 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

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.
 
309 6890 d 13 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
294 6891 d 14 h jermar /SPARTAN/trunk/arch/ Add timeout to kmp() so that we don't deadlock while waiting for AP's to come up.

Improve comment in byteorder.h.
 
293 6892 d 0 h palkovsky /SPARTAN/trunk/ Symbol table now contains static functions too.
NOTE: gcc heavily inlines, be aware of optimizations.

Removed excesive item from boot page tables.
 
292 6892 d 0 h jermar /SPARTAN/trunk/ Add byteorder.h to support conversions between different endianesses.
Add native_le2host().

Use native_le2host() in get_symtab_entry().
 
289 6892 d 4 h palkovsky /SPARTAN/trunk/ Added preprocessed linker script to AMD architecture, so that
the constants are all only in the header files.
 
287 6892 d 8 h jermar /SPARTAN/trunk/arch/ppc/ Symtab support for PPC.  
266 6893 d 9 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
254 6893 d 14 h decky /SPARTAN/trunk/arch/ppc/ fix stupid assembler bugs in cpu_priority_* (PPC)  
253 6893 d 15 h jermar /SPARTAN/trunk/arch/ Implement PPC's get_stack_base().

Comment AMD64's get_stack_base().
 
250 6894 d 4 h jermar /SPARTAN/trunk/arch/ppc/src/ Add missing semicolon.  
230 6895 d 8 h cejka /SPARTAN/trunk/arch/ Created fmath as basic tool for IEEE 754 floating point numbers.

This is required by get_stack_base().

Define 'THE' macro.

Implement preemption_disable() and preemption_enable().

Add memory barrier macros.
IA-32 macros need support for older processors.
