2139 6317 d 13 h decky /trunk/contrib/toolchain/ move to GCC 4.1.2, make scripts really host platform independent
remove orphaned libobjc		  
2138 6317 d 15 h decky /trunk/contrib/toolchain/ revert previous change (libobjc is actually HOST platform dependent)  
2137 6317 d 15 h kebrt /branches/arm/contrib/toolchain/ typo  
2136 6317 d 15 h kebrt /branches/arm/kernel/doc/ new developer  
2135 6317 d 20 h stepan /branches/arm/kernel/doc/ test commit  
2134 6318 d 16 h jermar /trunk/kernel/ Reworked handling of illegal virtual aliases caused by frame reuse.
We moved the incomplete handling from backend's frame method to
backend's page_fault method. The page_fault method is the one that
can create an illegal alias if it writes the userspace frame using
kernel address with a different page color than the page to which is
this frame mapped in userspace. When we detect this, we do D-cache
shootdown on all processors (!!!).

If we add code that accesses userspace memory from kernel address
space, we will have to check for illegal virtual aliases at all such
places.

I tested this on a 4-way simulated E6500 and a real-world Ultra 5,
which has unfortunatelly only one processor.

This solves ticket #26.		  
2133 6318 d 16 h jermar /trunk/kernel/generic/src/mm/ Coding style and indentation fixes.  
2132 6319 d 22 h jermar /trunk/kernel/generic/src/mm/ Fix coding style in the address space area backends.  
2131 6320 d 18 h decky /branches/ add development branches  
2130 6353 d 13 h jermar /tags/0.2.0.4/ Tagging 0.2.0.4 release.  
2129 6353 d 14 h jermar /trunk/ Fix small problem in sparc64 port.

Bump version to 0.2.0.4 (Sunset).		  
2128 6360 d 16 h jermar /trunk/ Add arm32 architecture. The 32 suffix is used to specify that 16-bit Thumb
instructions are not used. The arm32 code is mostly composed of placeholders
that need to be replaced by real implementation. So far, the arm32 tree
only compiles. If run under GXEmul simulator, an infinit loop at the
kernel entry point will be entered.		  
2127 6361 d 1 h decky /trunk/kernel/generic/src/lib/ add forgotten implementation  
2126 6361 d 12 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6361 d 15 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2124 6361 d 17 h decky /trunk/kernel/generic/ implement simple realloc()  
2123 6367 d 19 h decky /trunk/kernel/generic/src/mm/ add forgotten unsigned  
2122 6367 d 19 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2121 6367 d 20 h decky /trunk/kernel/generic/src/mm/ remove anonymous structure, add static qualifier  
2120 6367 d 20 h decky /trunk/kernel/generic/include/syscall/ specify syscall handler arguments
