113 Bug fix: the Makefile wasn't building gcc, and the binutils would not allocate
space for common variables or zero'd (bss) variables properly. Several binutils
bugs were fixed to get variables to be allocated properly. Those are
reflected in this updated patch.		 dgisselq 2941d 06h /zipcpu/trunk/sw/
112 Removed some debugging code from the compiler. dgisselq 2944d 01h /zipcpu/trunk/sw/
111 Bug fix compiler update! This fixes a lot of the bugs associated with the
previous compiler release.		 dgisselq 2944d 02h /zipcpu/trunk/sw/
110 The makefile no longer requires (or supports) building the obsolete machine
code test file optest.		 dgisselq 2944d 02h /zipcpu/trunk/sw/
109 This file is now marked as obsolete. dgisselq 2944d 02h /zipcpu/trunk/sw/
105 Fixed some nasty early branching bugs. Adjusted the Makefile to declare that
cpudefs.h was automatically generated from cpudefs.v, and made sure that
zipbones included the cpudefs.v so it could get the DEBUG_SCOPE define.
In addition, the test.S was updated to test long jumps, the early branching
bug we found, and all three early branching instructions: ADD #x,PC, LOC(PC),PC,
and LDI #x,PC.		 dgisselq 2960d 02h /zipcpu/trunk/sw/
104 An updated build script, actually builds zip-gcc. dgisselq 2961d 02h /zipcpu/trunk/sw/
103 A barely functional, but somewhat working, version of GCC to check in.
If the Lord is willing, it should be accompanied by a newlib port soon.
That port should move the GCC status from barely functional but somewhat
working to functional and working, although not (yet) complete.		 dgisselq 2961d 07h /zipcpu/trunk/sw/
102 Updated bugfix version of the binutils patch, and a first patch of GCC.
The GCC patch is undergoing ongoing and active development. It is also known to
continue to contain active bugs. (It's not done yet.)		 dgisselq 2963d 15h /zipcpu/trunk/sw/
101 Adjusted the "BREAK" instruction so that it will now disassemble properly
with an operand. This was necessary to create a (trap_if ...) instruction
for the GCC compiler.		 dgisselq 2965d 18h /zipcpu/trunk/sw/
