132 Lots of minor bug fixes. dgisselq 2948d 02h /zipcpu
131 Fixed a variable use before declaration error. dgisselq 2948d 02h /zipcpu
130 Simplified the lock logic, and removed it when pipelining was not defined. This
also means the file is now dependent upon cpudefs.v. In another change, brev
was modified so as not to update the flags. This makes it useable with GCC
as a potential move or load immediate instruction.		 dgisselq 2948d 02h /zipcpu
129 Bug fix. Fixes some ugly race conditions that would cause code from the wrong
address to be executed.		 dgisselq 2948d 02h /zipcpu
128 Cleaned up some comments. dgisselq 2948d 02h /zipcpu
127 Lots of changes and bugfixes. The disassembler produces more readable output.
The assembler and linker will no longer automatically use LDIHI--in preparation
for switching to LONG_MPY. LDIHI/LDILO pairs have been changed to BREV/LDILO
pairs. Within the compiler, conditional moves have been rebuilt. They're not
perfect yet, but they are better. Lots of peephole optimizations, etc.		 dgisselq 2948d 02h /zipcpu
126 Lots of changes preparing the assembly for an instruction set change. While
implemented, they are still commented out via #ifdef LONG_MPY. By defining
LONG_MPY, this new change set will take place.		 dgisselq 2948d 03h /zipcpu
125 This patch contains minor updates. Two are important to mention: 1) It turns
the compare optimizations back on within the zip.md file, and 2) it fixes an
internal compiler fault that was causing the compiler to such up all of my
memory in an infinite recursion.		 dgisselq 2956d 10h /zipcpu
124 Lots of changes, lots of bugfixes--both to the compiler as well as to the
assembler. (Ex: the assembler will now properly execute a LDI _sym+5,R0).
Many compiler optimizations have been turned off, however. They will probably
be turned back on in the near future--once I get this version proven without
them.		 dgisselq 2958d 00h /zipcpu
123 This test now catches and tests some of the pipeline bugs I've been chasing. dgisselq 2958d 00h /zipcpu
