Additional ZipCPU changes associated w 8b upgrade |
dgisselq |
2797d 23h |
/zipcpu/trunk/sw |
| 200 |
Lots of GCC bugs fixed, some new features added, longs should work now. The
build scripts have also been updated and simplified. |
dgisselq |
2897d 06h |
/zipcpu/trunk/sw |
| 192 |
Fixed a bug with constant alignment in the assembler. |
dgisselq |
2924d 00h |
/zipcpu/trunk/sw |
| 191 |
Updated toolchain, more information on the example debugger. |
dgisselq |
2939d 03h |
/zipcpu/trunk/sw |
| 188 |
Adjusted the opcodes to match the binutils port: added RTN instructions, and
allowed BREAK instructions to include an immediate--to be interpreted by the
debugger. |
dgisselq |
2972d 21h |
/zipcpu/trunk/sw |
| 171 |
This fixes the problem whereby the ZipCPU didn't properly access more than
5 word-sized function parameters. |
dgisselq |
2975d 03h |
/zipcpu/trunk/sw |
| 166 |
Bugfix version. This fixes a problem whereby function addresses with offsets
were not properly calculated, together with properly setting up pcrelative
offsets when using the move function together with a label. |
dgisselq |
3034d 02h |
/zipcpu/trunk/sw |
| 165 |
Added a test to make certain that the arithmetic right shift was properly
propagating the high order bit. (The test works under verilator, but didn't
initially work in Xilinx -- thus a difference between the two.) |
dgisselq |
3034d 02h |
/zipcpu/trunk/sw |
| 156 |
Fixed a compiler warning for an unused result. |
dgisselq |
3065d 18h |
/zipcpu/trunk/sw |
| 146 |
Fixes a problem where the assembler complained the compiler was trying to
move .org backwards. This is now fixed. |
dgisselq |
3098d 16h |
/zipcpu/trunk/sw |
| 143 |
This section belatedly adjusts the zasm assembler so that it can handle
the LONG_MPY changes that have taken place. However, the test.S assembler
test script is still not properly testing the multiplies--at least it will
succeed on everything else. |
dgisselq |
3098d 16h |
/zipcpu/trunk/sw |
| 142 |
Bug fix--fixes some problems with conditional execution, as well as removing
an unnecessary peephole optimization. |
dgisselq |
3099d 17h |
/zipcpu/trunk/sw |
| 141 |
Fixes two bugs: one causing merged strings in the read only string section to
be referenced at the wrong address, and the second which caused the assembler
to fail at SYMBOL-OFFSET references. |
dgisselq |
3099d 17h |
/zipcpu/trunk/sw |
| 138 |
This updates the CPU multiply instruction into a set of three instructions.
MPY is a 32x32-bit multiply instruction, returning the low 32-bit result,
MPYUHI returns the upper 32-bits assuming the result was unsigned and MPYSHI
returns the upper 32-bits assuming the result was signed. |
dgisselq |
3105d 03h |
/zipcpu/trunk/sw |
| 137 |
This should (again) fix the bug of trying to build optest.cpp. |
dgisselq |
3118d 20h |
/zipcpu/trunk/sw |
| 136 |
Oops --- missed a couple HOST_WIDE_INT values in a printf. This casts them
to (long), so that we can work on both PC's and ARMs. |
dgisselq |
3118d 21h |
/zipcpu/trunk/sw |
| 135 |
Replaced all occurrences of INTVAL(...) on printf lines with (long)INTVAL(...).
This should fix the problems zip-gcc was having while running on the ARM. |
dgisselq |
3118d 21h |
/zipcpu/trunk/sw |
| 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 |
3119d 18h |
/zipcpu/trunk/sw |
| 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 |
3119d 18h |
/zipcpu/trunk/sw |
| 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. |
