lib6502-jit implements (nearly) the same API as Ian Piumarta's lib6502
|
||
|
|
(http://www.piumarta.com/software/lib6502/) and includes virtually all of
|
||
|
|
lib6502's code and documentation with only minor modifications; the lib6502
|
||
|
|
emulation code is used to implement the interpreted and hybrid emulation modes
|
||
|
|
in lib6502-jit. The contents of the examples and man directories are almost
|
||
|
|
verbatim copies of those in lib6502. Thanks to Ian for making lib6502
|
||
|
|
available. Please do not send bug reports regarding lib6502-jit to Ian!

This distribution itself doesn't contain any LLVM code, but obviously without
|
||
|
|
the LLVM project lib6502-jit could not exist.
|

|
|
|
||
|
|
valgrind.h is taken from Valgrind (http://valgrind.org/).
|
||
|
|
|
||
|
|
build-aux/tap-driver.sh is part of GNU Automake and was taken from
|
||
|
|
https://raw.githubusercontent.com/kergoth/automake/master/lib/tap-driver.sh.
|
||
|
|
|
||
|
|
m4/boost.m4 (used to autoconfigure the build against the Boost libraries) is
|
||
|
|
taken from https://github.com/tsuna/boost.m4.
|
||
|
|
|
||
|
|
While I'd be lying if I said I enjoyed working with Autotools, I am grateful
|
||
|
|
for the work people have put in to make it possible to build packages portably
|
||
|
|
on a range of different platforms.

The technique (but not the code) used to translate a JITted function's machine
|
||
|
|
code into assembly in Function::dump_machine_code() is taken from the libjit
|
||
|
|
(https://www.gnu.org/software/libjit/) dump_object_code() function.
|
||
|
|
|
||
|
|
The algorithm used to implement ADC/SDC in decimal mode is taken from
|
||
|
|
http://www.6502.org/tutorials/decimal_mode.html. The test program on the same
|
||
|
|
page was used to validate the implementation.
|
||
|
|
|
||
|
|
Klaus Dormann's "6502 functional test" and "65C02 extended opcodes test" were
|
||
|
|
used to validate the behaviour of the emulation.
