Current
Added
Added support for \f, \v and \e Added refresh to bootstrap.sh to build seed from cc_x86.s Added missing license headers
Changed
Converted M2-Planet to use GNU style error message Seed.M1 when built will now have the same checksum as M2-Planet self-hosted Harmonized license headers
Fixed
Fixed typo in file headers Fixed version number to reflect current version Thanks to akkartik several documentation issues were identified and fixed
Removed
1.0 - 2018-08-26
Added
Added more generic logic to lookup_type Added prim_types to simply the task of reducing search space to primitives
Changed
Reorganized Primitive expression evaluation Reorganized Collect_local to better match implementation Broke out process_break Changed ordering in declare_function to reduce stack operations Converted weird_string collection into a simpler form Inlined 2 small stubs as breaking them out wouldn't help implementation Reordered conditionals for easier implementation and reduced operations Broke out OUT and FUNCTION to silence a single GCC warning Moved required_match and line_error into cc_core.c and removed required_match.c Relocated contents of test/functions to functions Upgrades mescc-tools to 40537c0200ad28cd5090bc0776251d5983ef56e3 commit Tweaked order for for, while and do loops to make them more in commone Tweaked source to better match assembly Simplify implementation order of logic Simplifed the promote_type logic to a much breifer form Broke out generally useful member lookup Upgraded seed.M1 to be generated by cc_x86
Fixed
Fixed detection of locals to screen out all non-primitive name space collisions Checked in updated gcc function definition Changed's numerate_number's behavior related to zeros Improved error message to help debugging Fixed bootstrap.sh to build a working M2-Planet binary
Removed
Removed redundent steps in Recursive statement Removed several redundent steps in Collect_arguments
0.3 - 2018-08-12
Added
Added support for global intializers Introduced base offset local and argument load/store Added function pointer requirement into M2-Planet Added test24 - get_machine Added General_Recursion to reduce complexity Added uniqueID to purge all code segments that recreate it's functionality Added struct Char arrays for structs Added in_set to make complex conditional logic into a simple char search
Changed
Made String naming 100% deterministic Broke up all_expr to simplify any manual implementations Cleaned up function calls Simplify variable looksup Reused a union to reduce globals Brought back common recursion Reorged logic tree to reduce complexity Simplified expression Changed EOF detection logic to deal with unsigned bits Reduced Memory usage down from 50MB to 2MB Simplified Tokenizer logic for easier implementation and understanding Simplified program logic Significantly reduced weird string detection logic Trimmed escape_lookup down to a key core Eliminated Several Minor unneeded steps
Fixed
Correct bug in how \" is treated Clean up of & when && should have been used Made test22 for consistent Fixed !c->a regression Fixed ARM platform build Reduced Memory usage per Token to size of string plus fixed padding
Removed
Removed need for string copying in M2-Planet Wasted steps in stack offsets Need for stack relative offsets Extra stack walks Removed need for current_function Removed unused values Removed legacy x86 << >> hacks at the cost of more instructions
0.2 - 2018-06-21
Added
Added type promotion to allow progress on mes.c Add support for anonymous unions inside of structs Added support for passing of function pointers via FUNCTION Added support for Local functions Added support for EOF Added additional debug information to M2-Planet Added line numbers and files names for errors in parsing to help debug Added support for close and fclose Added prototype support for chmod Added basic support for escape strings Added support for continue Added string_length function to string.c Added function numerate_string for converting string to integer Added supporting hex2char, char2hex, dec2char and char2dec functions Added support bitwise xor Added Blood-elf test Added Hex2_linker test Added M1-macro test Added prototypes to allow functions to be independently built Added support for debug format output to help debugging Added function specific counters to make output even more deterministic Added M1-macro seed to eliminate C compiler dependency for bootstrap
Changed
Improving Documentation to help new programmers get functional Cleaned up numerate_number to make it more general purpose Enabled stand alone builds of calloc Unified bitwise operations Made string.c more independent Created a M1-macro stub file to simplify independent builds Created a hex2_linker stub file to simplify independent builds Created a blood-elf stub file to simplify independent builds
Fixed
Minor cleanup and removal of unneeded whitespace Fixed outstanding bug when struct foo* foo and foo->bar was used Fixed ":foo bug Fixed "\n:foo bug Adjusted all previous references to numerate_number to ensure output is consistent Fixed up reader so that '\'' and "\"" work correctly now fixed "\"" bug in string output generation
Removed
Removed need for memset in numerate_number Removed minimal build target as it no longer serves a purpose Removed independent counters for for, while and if jumps
0.1 - 2018-02-23
Added
Added example programs Added first generation libc Added first generation defs.M1 added FOR Loop support along with example Added support for assembly statements Added CONSTANT to the language Added support for <. >= and > expressions Added struct support Added unary - and ! support Added additional functionality such as mixed structs, do while loops, gotos and tests for the new functionality Incorporate breaks into loops Became Self-Hosting
Changed
Tweaked argument processing to help mescc support Isolated global_token to cc.c Moved strings to the bottom of the output Broke out globals Started to move type information out of hard-coded logic Started adding tests instead of examples Put common x86 platform logic in a shared folder to reduce duplicate code Converted from legacy M2-Planet Input.c Output.c to M2-Planet -f input.c … -f Minor reordering of tests
Fixed
expanded type support to include integer arrays Reduced the memory churn in string creation fixed Capitalization problems
Removed
Removed need for enum in bootstrapping Removed need for global output list Eliminated the global stack Reduced library dependencies
