Changed
Updated build.sh and kaem.run to the current mescc-tools syntax Reduced get_machine's build dependencies Cleaned up x86 elf headers Removed kaem's dependence on getopt Replaced --Architecture with --architecture changed get_machine's default output to filter machine names into known families Reduced M1 null padding of strings to a single null for all architectures except Knight Updated AMD64 bootstrap kaem.run to include steps from hex0 to M0
Fixed
Fixed broken test9 thanks to janneke Fixed wrong displacement calculations for ARM immediates Fixed typo in license header Fixed kaem.run to actually function and produce identical results Fixed regression caused by linux 4.17 Removed false newline added in numerate_number for zero case Fixed broken bootstrap script
Removed
Removed final dependency on getopt Removed need to know architecture numbers as that was a bad idea
0.5 - 2018-06-15
Added
Added INSTALL notes Added HACKING notes Added examples of minimal Hex1, Hex2 and M1-macro programs that may need to be written to bootstrap a particular architecture. Added useful functions to reduce bootstrap dependencies Added support for binary output in M1-macro
Changed
Changed Knight architecture offset calculation to match new standard Updated test3 lisp.s to include more functionality Updated test3 definitions file to reflect changes in Knight instruction encoding enhanced README to be more useful Pulled numerate_string functionality out of hex2 and M1 into a shared library Eliminated getopt from M1-Macro, hex2-linker and blood-elf; use --Architecture 1 instead of --Architecture=1
Fixed
Corrected M1-macro incorrectly expressing negative numbers Updated test3 checksum to reflect new version of lisp.s fixed check.sh to actually perform all checks. Fixed build.sh to function in a self-hosting fashion
Removed
Removed blood-elf's dependency on getopt Removed C preprocessor macro from blood-elf needed for mescc support Removed hex2's dependency on getopt Removed C preprocessor macro from hex2 needed for mescc support Removed need for octal support in the building of hex2 Removed M1's dependency on getopt Removed C preprocessor macro from M1 needed for mescc support Removed need for sprintf from M1
0.4 - 2018-02-24
Added
Added file checks to reduce the number of error messageless faults Added a current generation M1.M1 file as a test for mescc-tools Added prototype kaem build script M1-macro now catches undefined macros to allow easier troubleshooting Added kaem build tool Added ability to track build progress in kaem Added support for line escapes in kaem Added support for --strict in kaem to halt in the event of errors Added selectable script file support in kaem Added support for PATH search to kaem with fallbacks in the event of NULL environments
Changed
flipped blood-elf from ignoring :: to :_ converted test8 into a full test Added bash style line comments to kaem Added support for raw strings to kaem Stopped showing comment lines in kaem --verbose Removed dependence on getenv to have more control over environmental lookup
Fixed
Fixed stack overflow bug caused by too deeply nested recursion by transforming into iteration Fixed default repo to point to current repo Added missing license header to kaem.c Fixed infinite looping in kaem scripts that hit an error that resets the file descriptor
Removed
Removed need for strtol Removed need for a global variable in M1-Macro Removed legacy functions from kaem
0.3 - 2017-12-01
Added
Incorporated a hex0 test which implements hex1 functionality Added --output and --exec_enable options to hex2 Added --output option to M1
Wrote Hex1 in Hex0 for AMD64/ELF Added the ability to specify an output file Added exec_enable to allow the arbitrary setting of executable bits Added get_machine to enable better scripting Incorporated janneke's build scripts Added a test to test for unusual nybble and byte order/formatting issues Added blood-elf to generate elf footer capable of being used by objdump
Changed
Renamed MESCC_Tools to mescc-tools to harmonize with guix package name
Now all tests will be architecture specific Modified sprintf to behave correctly for negative numbers Converted blood-elf to read M1-macro input and output M1-macro output replaced uint with unsigned to better match the standard Harmonized MAXSTRING to 4096bytess
Fixed
Incorporated janneke's patchs to fix mescc compatibility Fixed test on ARM platforms Fixed range check to behave correctly with unsigned ints
Removed
Removed the need to redirect hex2 output into a file Removed the need for chmod u+x in development paths Removed the need to redirect M1 output into a file Removed the need for chmod entirely from bootstrap path

Changed
Adjusted tags to reflect current CHANGELOG Make test now depends upon test2 completing Changed how M0 processes input to reduce stack usage and improve performance Renamed M0 to M1 to reflect the additional functionality it provides Applied Janneke's patch for accepting hex numerics in M1 Refactored x86/amd64 elf headers to a standard to avoid duplication Standardized C flags for compiling M1 and Hex2 Made eval_immediates iterative instead of recursive Made identify_macros iterative instead of recursive Made process_string iterative instead of recursive Made preserve_other iterative instead of recursive Made print_hex iterative instead of recursive Incremented version numbers for hex2 and M1 Updated guix.scm to match the new version and finish the release Converted guix.scm definition for mescc_tools to use uri method instead of git
Fixed
Removed unrequired temp file in test1 Clarified meaning of Label>base displacement conditional Corrected error in test0 elf32 Test1 and Test2 to reflect the fact that /bin/bash doesn't exist in guix Fixed M0 regression to continue to support original test code Corrected makefile and build scripts to reflect rename Modified test make scripts to reflect new standard elf headers Fixed base address needed by test5 and its associated checksum Harmonized flags for displaying version with standard
Removed
Removed bashisms from Test1 and Test2 to allow proper behavior on debian based systems Removed alerting on missing files in cleanup target Removed massive M0 Definition lists as they don't serve a useful purpose
